factors affecting crop production wikipedia
, Livestock production systems can be defined based on feed source, as grassland-based, mixed, and landless. There are numerous factors affecting corn production. , In the Americas, crops domesticated in Mesoamerica (apart from teosinte) include squash, beans, and cocoa. , Agriculture lead to rise in Zoonotic disease like the Coronavirus disease 2019, by degrading natural buffers between humans and animals, reducing biodiversity and creating big groups of genetically similar animals.  After 1492 the Columbian exchange brought New World crops such as maize, potatoes, tomatoes, sweet potatoes and manioc to Europe, and Old World crops such as wheat, barley, rice and turnips, and livestock (including horses, cattle, sheep and goats) to the Americas.  Since the Industrial Revolution, many countries have made the transition to developed economies, and the proportion of people working in agriculture has steadily fallen.  The Push–pull agricultural pest management technique involves intercropping, using plant aromas to repel pests from crops (push) and to lure them to a place from which they can then be removed (pull). Hoffmann, U., Section B: Agriculture – a key driver and a major victim of global warming, in: Lead Article, in: Chapter 1, in. This paper presents an overview of the impacts of various climatic factors on crop production.  The sociologist C. Wright Mills refers to "new entrepreneurs" who work within and between corporate and government bureaucracies in new and different ways. Crop Production", pp. It is practiced mainly in developed countries.  Entrepreneurship is also sometimes considered a factor of production. There is not enough water to continue farming using current practices; therefore how critical water, land, and ecosystem resources are used to boost crop yields must be reconsidered. Kropotkin does not argue that the product of a worker's labor should belong to the worker. Prezi. Because of the low biodiversity, nutrient use is uniform and pests tend to build up, necessitating the greater use of pesticides and fertilizers. Another patch of land is selected and the process is repeated.  Future climate change will probably negatively affect crop production in low latitude countries, while effects in northern latitudes may be positive or negative. It integrates, among other things, the first and second laws of thermodynamics (see: Laws of thermodynamics) to formulate more realistic economic systems that adhere to fundamental physical limitations.  One of the major forces behind this movement has been the European Union, which first certified organic food in 1991 and began reform of its Common Agricultural Policy (CAP) in 2005 to phase out commodity-linked farm subsidies, also known as decoupling.  Others (such as those practicing public choice theory) refer to "political entrepreneurs", i.e., politicians and other actors. The factors are also frequently labeled "producer goods or services" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods". Global cattle, sheep and goat populations are expected to continue to increase sharply through 2050. Differences are most stark when it comes to deciding which factor is the most important. These seeds allow the farmer to grow a crop that can be sprayed with herbicides to control weeds without harming the resistant crop. The reasons are outlined below:PhysicalClimateClimatic factors include...1. Factors That Affect Regular Plant Growth Can Also Be Applied To Crop Growth. C. H. Douglas disagreed with classical economists who recognized only three factors of production. 1.  In Greece and Rome, the major cereals were wheat, emmer, and barley, alongside vegetables including peas, beans, and olives. Fig. Plants were independently cultivated in at least 11 regions of the world. , Water management is needed where rainfall is insufficient or variable, which occurs to some degree in most regions of the world. Recent usage has distinguished human capital (the stock of knowledge in the labor force) from labor. Crop Enemies 5.  Working animals, including horses, mules, oxen, water buffalo, camels, llamas, alpacas, donkeys, and dogs, have for centuries been used to help cultivate fields, harvest crops, wrangle other animals, and transport farm products to buyers.  Economists measure the total factor productivity of agriculture and by this measure agriculture in the United States is roughly 1.7 times more productive than it was in 1948. , Since the 1940s, agricultural productivity has increased dramatically, due largely to the increased use of energy-intensive mechanization, fertilizers and pesticides. The techniques are meant to increase farm production and output for higher returns. Global warming will probably increase the risk of food insecurity for some vulnerable groups, such as the poor . Factors influencing maize crop production at household levels: A case of Rukwa Region in the southern highlands of Tanzania March 2015 African Journal of … Internal factors . , Pesticide use has increased since 1950 to 2.5 million short tons annually worldwide, yet crop loss from pests has remained relatively constant. Factors Affecting Crop Production 126 Limitations of Traditional Plant Breeding 1. Water may be considered as one of the most limiting factors in increasing food production. Efficiency scores obtained from Data Envelop Analysis (DEA) were used as the dependent variable. Factors affecting crop growth. Then, wild stands that had previously been harvested started to be planted, and gradually came to be domesticated. , Animal husbandry is also responsible for greenhouse gas production of CO2 and a percentage of the world's methane, and future land infertility, and the displacement of wildlife. Temperature: Most plants cannot grow if the temperature falls below 6°C or the soil is frozen for five consecutive months. , Classical price theory follows "costs of reproduction" and does not allow for "factor" gains.  Modern agriculture has raised or encountered ecological, political, and economic issues including water pollution, biofuels, genetically modified organisms, tariffs and farm subsidies, leading to alternative approaches such as the organic movement. , Other GMO crops used by growers include insect-resistant crops, which have a gene from the soil bacterium Bacillus thuringiensis (Bt), which produces a toxin specific to insects. "Practical Nutrient Management" pp.  Mixed production systems use grassland, fodder crops and grain feed crops as feed for ruminant and monogastric (one stomach; mainly chickens and pigs) livestock. Because of this, Kropotkin proclaims that every human deserves an essential right to well-being because every human contributes to the collective social product: Kropotkin goes on to say that the central obstacle preventing humanity from claiming this right is the state's violent protection of private property. , In 2010, the International Resource Panel of the United Nations Environment Programme assessed the environmental impacts of consumption and production. 110 years of biological control research and development in the United States Department of Agriculture: 1883–1993. Climate factors : (e) Light : Plant produces carbohydrate using CO 2 and water with the help …  Increasing pressure is being placed on water resources by industry and urban areas, meaning that water scarcity is increasing and agriculture is facing the challenge of producing more food for the world's growing population with reduced water resources. Classification of elements affecting crop production 1. "White Collar: The American Middle Classes," 1956. Scientists estimate that 75% of the growth in livestock production between 2003 and 2030 will be in confined animal feeding operations, sometimes called factory farming. Some of these include: Salinity stress affects crop production in over 30% of irrigated crops and 7% of dry land agriculture worldwide .  Wild grains were collected and eaten from at least 105,000 years ago. , Industrialized agriculture depends on fossil fuels in two fundamental ways: direct consumption on the farm and manufacture of inputs used on the farm. Weather, 2. Previous Crop, 5. Estimates of the amount of land transformed by humans vary from 39 to 50%. Further distinctions from classical and neoclassical microeconomics include the following: Ecological economics is an alternative to neoclassical economics).  240–282 in, "Nutrition from the Soil", pp. Outside nutrient inputs may be used, however manure is returned directly to the grassland as a major nutrient source.  A range of policies can reduce the risk of negative climate change impacts on agriculture, and greenhouse gas emissions from the agriculture sector. Global warming affects agriculture through changes in average temperatures, rainfall, and weather extremes (like storms and heat waves); changes in pests and diseases; changes in atmospheric carbon dioxide and ground-level ozone concentrations; changes in the nutritional quality of some foods; and changes in sea level. , Agriculture imposes multiple external costs upon society through effects such as pesticide damage to nature (especially herbicides and insecticides), nutrient runoff, excessive water usage, and loss of natural environment. Myself Vijay Kumar Shrivastav completed M.Sc. Douglas carefully distinguished between value, costs and prices. Direct consumption includes the use of lubricants and fuels to operate farm vehicles and machinery. , Agricultural policy is the set of government decisions and actions relating to domestic agriculture and imports of foreign agricultural products. When grain prices are very low, farmers with irrigated lands tend to look at the high prices, take out their calculators and do some quick sums: 45 000 cabbages/ha with eight to 10 heads in a bag at R90/ bag adds up to R450 000/ ha. This is related to the greater efficiency of farming, combined with the increased level of value addition (e.g.  Some studies also link widespread glyphosate usage to iron deficiencies in some crops, which is both a crop production and a nutritional quality concern, with potential economic and health implications. 1. The hiring of labor power only results in the production of goods or services ("use-values") when organized and regulated (often by the "management"). These could include credit, Extension Workers (EWs) or Development Agents (DAs) and agricultural cooperatives. The "instruments of labor" are tools, in the broadest sense. WEEK 4.  Demand for non-food biofuel crops, development of former farm lands, rising transportation costs, climate change, growing consumer demand in China and India, and population growth, are threatening food security in many parts of the world. , According to a report by the International Food Policy Research Institute, agricultural technologies will have the greatest impact on food production if adopted in combination with each other; using a model that assessed how eleven technologies could impact agricultural productivity, food security and trade by 2050, the International Food Policy Research Institute found that the number of people at risk from hunger could be reduced by as much as 40% and food prices could be reduced by almost half. Climatic conditions extend beyond just “wet” and “dry”. Food classes include cereals (grains), vegetables, fruits, oils, meat, milk, fungi and eggs. Agriculture is the science and art of cultivating plants and livestock. Top Seven Factors in Crop Production In march the Pioneer Growing Point e-newsletter had an article I was interested in which listed and ranked the top seven factors in crop production. Pesticides kill insects, plants and fungi. During this decision making process, farmers cross check the suitability of proposed crop/cropping systems with their existing resources and other conditions. ", Land transformation, the use of land to yield goods and services, is the most substantial way humans alter the Earth's ecosystems, and is considered the driving force in the loss of biodiversity.  Nutrients 4.  In India, wheat, barley and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Variations in yields are due mainly to variation in climate, genetics, and the level of intensive farming techniques (use of fertilizers, chemical pest control, growth control to avoid lodging). Similarly, worldwide average wheat yields have increased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990. 25–57 in, Brady, N. C.; Weil, R. R. (2002). These crops resist damage by insects. , Subsistence farming is practiced to satisfy family or local needs alone, with little left over for transport elsewhere. Biotic factors are the living components of an ecosystem. ), "Agricultural Production Systems". It is one of the major problems affecting crop production all over the world since around 20% of cultivated land and 33% of irrigated land are salt-affected in the world . Top Seven Factors in Crop Production In march the Pioneer Growing Point e-newsletter had an article I was interested in which listed and ranked the top seven factors in crop production. FACTORS AFFECTING AGRICULTURAL PRODUCTION IN TIGRAY REGION, NORTHERN ETHIOPIA by BIHON KASSA ABRHA Submitted in accordance with the requirement for the degree of DOCTOR OF LITERATURE AND PHILOSOPHY in the subject DEVELOPMENT STUDIES at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: PROF. ESTHER KIBUKA-SEBITOSI July 2015 Student Number: 4551-821-1 . India ranks second worldwide in farm outputs. The factors are also frequently labeled "producer goods or services" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods". This process is called photosynthesis. , Intensive farming is cultivation to maximise productivity, with a low fallow ratio and a high use of inputs (water, fertilizer, pesticide and automation). For example, J. In some cases, wild species are the primary source of resistance traits; some tomato cultivars that have gained resistance to at least 19 diseases did so through crossing with wild populations of tomatoes. Increased durability, nutritional content, insect and virus resistance and herbicide tolerance are a few of the attributes bred into crops through genetic engineering. Consequently, mankind does not have to keep "reinventing the wheel". Integrated pest management attempts to use all of these methods to keep pest populations below the number which would cause economic loss, and recommends pesticides as a last resort.  Together, direct and indirect consumption by US farms accounts for about 2% of the nation's energy use. , In subtropical and arid environments, the timing and extent of agriculture may be limited by rainfall, either not allowing multiple annual crops in a year, or requiring irrigation. UNEP, 2011, Towards a Green Economy: Pathways to Sustainable Development and Poverty Eradication, "Strategies for Pest Control", pp. It is one of the major problems affecting crop production all over the world since around 20% of cultivated land and 33% of irrigated land are salt-affected in the world . Measures might include paying for reforestation upstream of a city, to improve the supply of fresh water. These nutrients are major nonpoint pollutants contributing to eutrophication of aquatic ecosystems and pollution of groundwater, with harmful effects on human populations. Genetic or Internal Factors 2.  As of 2010[update], 30% of Earth's ice- and water-free area was used for producing livestock, with the sector employing approximately 1.3 billion people. Economic Factors Affecting Farming Significant advances in plant breeding ensued after the work of geneticist Gregor Mendel. Paragraph 4, in: Summary and Recommendations, in: Section 4.2: Agriculture's current contribution to greenhouse gas emissions, in: Current climate change policies are described in, Coulson, J. R.; Vail, P. V.; Dix M. E.; Nordlund, D. A.; Kauffman, W. C.; Eds.  As an industry in which families commonly share in work and live on the farm itself, entire families can be at risk for injuries, illness, and death. between the climatic factors like temperature, rainfall, solar radiation, CO 2 concentration, etc and crop yield need to be understood to take necessary adaptation measures to maintain the crop production. The previously mentioned primary factors are land, labour and capital. Crop production is affected by a number of abiotic factors including temperature, salinity, drought, pesticides, pH of the soil, and heavy metals as they affect all metabolic activities of the plant. Land includes not only the site of production but also natural resources above or below the soil. Altering crops through breeding practices changes the genetic make-up of a plant to develop crops with more beneficial characteristics for humans, for example, larger fruits or seeds, drought-tolerance, or resistance to pests. , Tillage is the practice of breaking up the soil with tools such as the plow or harrow to prepare for planting, for nutrient incorporation, or for pest control.  Cattle, sheep and goats were domesticated in Mehrgarh culture by 8,000–6,000 BC.  Adam Smith, David Ricardo, and Karl Marx claimed that labor creates all value. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and environmental damage. Under normal conditions, the higher osmotic pressure … TOPIC: 6 Biotic Factors Affecting Agricultural Production A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes. Over- extraction of water resources from aquifers and rivers has led to much loss of this resource. MEASUREMENT OF FACTORS AFFECTING CROP PRODUCTION T. F. GLOVER Department of Economics Utah State University Logan, Utah 84321 Introduction This … It is intensively practiced in Monsoon Asia and South-East Asia. , Payment for ecosystem services is a method of providing additional incentives to encourage farmers to conserve some aspects of the environment. Salt causes osmotic stress and ionic toxicity in crop plants. There is ongoing discussion regarding the labeling of foods made from GMOs, and while the EU currently requires all GMO foods to be labeled, the US does not. Among the oilseeds, sesame had the greatest amount of taxation, but overall, feed grains and oilseeds had much lower levels of taxation than livestock products.  In North America, the indigenous people of the East domesticated crops such as sunflower, tobacco, squash and Chenopodium. Salinity stress affects crop production in over 30% of irrigated crops and 7% of dry land agriculture worldwide . Tillage Choices, and 7.  Ages 0–6 May be an especially vulnerable population in agriculture; common causes of fatal injuries among young farm workers include drowning, machinery and motor accidents, including with all-terrain vehicles.  Other potential practices include conservation agriculture, agroforestry, improved grazing, avoided grassland conversion, and biochar.  Although the study of agricultural economics is relatively recent, major trends in agriculture have significantly affected national and international economies throughout history, ranging from tenant farmers and sharecropping in the post-American Civil War Southern United States to the European feudal system of manorialism. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. "Factors affecting efficiency of field crop production among resettled farmers in Zimbabwe," 2013 Fourth International Conference, September 22-25, 2013, Hammamet, Tunisia 161443, African Association of Agricultural Economists (AAAE). It is one of the largest sources of greenhouse gases, responsible for 18% of the world's greenhouse gas emissions as measured in CO2 equivalents. These factors also affect the internal and chemical features of plants which, to dig deeper, are responsible for the expression of the diverse external traits. For example, average yields of corn (maize) in the US have increased from around 2.5 tons per hectare (t/ha) (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001. Some of these include:  Current mono-crop farming practices in the United States preclude widespread adoption of sustainable practices, such as 2-3 crop rotations that incorporate grass or hay with annual crops, unless negative emission goals such as soil carbon sequestration become policy.  Agriculture is defined with varying scopes, in its broadest sense using natural resources to "produce commodities which maintain life, including food, fiber, forest products, horticultural crops, and their related services". "History and Development of Biological Control (notes)", "Biological Control of The Gypsy Moth: An Overview", "Agricultural and food policy choices in Australia", "Corporate Lobbying Is Blocking Food Reforms, Senior UN Official Warns: Farming Summit Told of Delaying Tactics by Large Agribusiness and Food Producers on Decisions that Would Improve Human Health and the Environment", "Agriculture collected news and commentary", Agriculture collected news and commentary, List of organic gardening and farming topics, https://en.wikipedia.org/w/index.php?title=Agriculture&oldid=999288293, Wikipedia pages semi-protected against vandalism, All Wikipedia articles written in American English, Short description is different from Wikidata, Articles containing potentially dated statements from 2010, All articles containing potentially dated statements, Wikipedia articles in need of updating from September 2020, All Wikipedia articles in need of updating, Articles containing potentially dated statements from 2009, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 January 2021, at 12:15. Crop breeding includes techniques such as plant selection with desirable traits, self-pollination and cross-pollination, and molecular techniques that genetically modify the organism. Weeds also reduce crop productivity by competing with the main crop for nutrients and light. Weather, 2. Market concentration has increased in the sector as well, and although the total effect of the increased market concentration is likely increased efficiency, the changes redistribute economic surplus from producers (farmers) and consumers, and may have negative implications for rural communities. F actors affecting agricultural production. ii | P … COLLEGES. Matter — the material from which products are produced. In D. R. Harris (ed.  A 2005 analysis of these costs in the US concluded that cropland imposes approximately $5 to $16 billion ($30 to $96 per hectare), while livestock production imposes $714 million. It also provides the scientific principles on which production technology is based.  Wild foods including wild rice and maple sugar were harvested.  Livestock production occupies 70% of all land used for agriculture, or 30% of the land surface of the planet. However, it developed an alternative theory of value and distribution.  The UN-FAO report cites land management as the driving factor behind degradation and reports that 1.5 billion people rely upon the degrading land.  Sometimes the overall state of technology is described as a factor of production. In contrast, many economists today consider "human capital" (skills and education) as the fourth factor of production, with entrepreneurship as a form of human capital. Some of the factors that affect crop production are explained below: 1. Degradation can be deforestation, desertification, soil erosion, mineral depletion, or chemical degradation (acidification and salinization). Management. The effects of these organisms on crop growth and yield are varied. Excessive fertilization and manure application to cropland, as well as high livestock stocking densities cause nutrient (mainly nitrogen and phosphorus) runoff and leaching from agricultural land.  These spread westwards across Eurasia. Crop production is a branch of agriculture that deals with growing crops for use as food and fiber.  Pig production emerged in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago.  Between the 1960s and the 1980s, the Green Revolution transformed agriculture around the globe, with world grain production increasing significantly (between 70% and 390% for wheat and 60% to 150% for rice, depending on geographic area) as world population doubled. 355–383 in. Marx considered the "elementary factors of the labor-process" or "productive forces" to be: The "subject of labor" refers to natural resources and raw materials, including land. Many of its practitioners have added various further factors of production (see below). Factor affecting crop production 1. Factors influencing decisions on the selection of crops & cropping system. We can place different forms of energy on a scale of utility depending on how useful it is for creating a product. , In shifting cultivation, a small area of forest is cleared by cutting and burning the trees.  Multiple cropping, in which several crops are grown sequentially in one year, and intercropping, when several crops are grown at the same time, are other kinds of annual cropping systems known as polycultures. Temperature decreases with increase in altitude, such that for every 300 meters rise in altitude above … This videos is about brief description of factors affecting crop production In other areas such as the Great Plains in the U.S. and Canada, farmers use a fallow year to conserve soil moisture to use for growing a crop in the following year. (2003) "Origin of rice cultivation in the Yangtze River basin". Pigs, sheep and cattle were domesticated over 10,000 years ago. Biotic factors would include the availability of food organisms and the presence of biological specificity, competitors, predators, and parasites These and other measures have cut biodiversity to very low levels on intensively farmed land. This trend has led to a significant decrease in genetic diversity and resources among livestock breeds, leading to a corresponding decrease in disease resistance and local adaptations previously found among traditional breeds. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago. This concerns such issues as the relative importance of market failure and government failure. environmental factors affecting crop production pdf Agricultural production, including food and other crops and livestock husbandry, is determined.ice, Eastem Oregon Agricultural Research Center, Squaw Butte … 1. NUMBER OF PRODUCTION UNITS The most basic factor affecting profit in any business is the number of production units. Crop production is a common agricultural practice followed by worldwide farmers to grow and produce crops to use as food and fibre. Tillage varies in intensity from conventional to no-till. Ans: Biotic factors such as pests, insects and diseases reduce the crop production. His work on dominant and recessive alleles, although initially largely ignored for almost 50 years, gave plant breeders a better understanding of genetics and breeding techniques. , Domestication of plants has, over the centuries increased yield, improved disease resistance and drought tolerance, eased harvest and improved the taste and nutritional value of crop plants. , In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on the Tigris and Euphrates rivers and a canal system for irrigation. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, "field", and cultūra, "cultivation" or "growing". Factors affecting crop production climatic edaphic - biotic- physiographic and socio economic factors. In the first half of the 20th century, some authors added the work of organization or entrepreneurship as a fourth factor of production. Temperature is influenced by altitude and topography. Environmental Factors: What and How Do They Affect Crop Growth and Yield Environmental factors are those non-genetic factors which contribute to the characteristics of a plant.  Cotton was domesticated in Peru by 3,600 BC. Agriculture accounts for less than one-fifth of food system energy use in the US. The techniques are meant to increase farm production and output for higher returns. Hybrid Selection, 4. Overall production varies by country as listed. Factors affecting crop production climatic –– edaphic - biotic- physiographic and socio economic factors .  From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Their knowledge of the season in their own localities is essential for each team to obtain. Nutrient inputs can be chemical inorganic fertilizers, manure, green manure, compost and minerals.  Animals including llamas, alpacas, and guinea pigs were domesticated there. When crops are over-irrigated, water, energy, labour, and fertiliser are wasted and crop production can decrease.  Asian rice was domesticated 8,200–13,500 years ago – depending on the molecular clock estimate that is used – on the Pearl River in southern China with a single genetic origin from the wild rice Oryza rufipogon. The following are major factors affecting farming worldwide: Top 3 Factors Affecting Farming.
