b the yield of some other farm produce. The seed ratio is another way of calculating agricultural productivity. [1] Each technological advance increasing the crop yield also reduces the society's ecological footprint. Measurement. 10 percent from one year to the next. c (1) : to produce as return from an expenditure or investment : furnish as profit or interest a bond that yields 12 percent. Sample sizes of a harvested crop are generally measured to determine the estimated crop yield. Crop production depends on the availability of arable land and is affected in particular by yields, macroeconomic uncertainty, as well as consumption patterns; it also has a great incidence on agricultural commodities' prices. [citation needed] In parts of Europe the seed ratio during the 9th century was merely 1:2.5, in the Low Countries it improved to 1:14 with the introduction of the three-field system of crop rotation around the 14th century. resistance crops like pearl millet, sorghum and minor millets are grown. Moreover, since wheat is 27.215 kg/bu, the yield we estimated would be 40 bu/acre (1097/27.215) or 40 bushels per acre. Crop Production Definition “Crop production is the branch of agriculture that deals with the production of crops for food and fiber.” What Is Crop Production? In agriculture, crop yield refers to the measure of seeds or grains which is generated from a unit of land. For the collection of crop area statistics, both subjective and objective methods are currently used around the world. In agriculture, crop yield potential refers to the output of a crop cultivar when grown with nutrients and water. Sample sizes of a harvested crop are measured to determine the estimated crop yield. Crop yield determination is a crucial function in planning for food security of the population of a district or even of the whole country. Crop yield can also refer to the actual seed generation from the plant. How to use crop in a sentence. In agriculture, the yield (also known as "agricultural productivity" or "agricultural output") is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. to clarify the definition of yield gap and the various methods used to estimate it. For example, a grain of wheat yielding three new grains of wheat would have a crop yield of 1:3. Innovations, such as the use of fertilizer, the creation of better farming tools, new methods of farming and improved crop varieties, have improved yields. Agribusiness is the business sector encompassing farming and farming-related commercial activities. It rates all soils that are used for the production of commodity crops. To solve the problem, we need to forecast the crop yield (average food production within a region, usually measured in bushel/acre) before harvest in a given year. This year, the yield limitation will be an option that must be added or deleted by the Sales Closing deadline on a crop/county basis. b : to produce or furnish as return this soil should yield good crops. The four most important factors that influence crop yield are soil fertility, availability of water, climate, and diseases or pests. Advantages and Disadvantages of Crop Yield. In certain cases, APH yields can be adjusted using Yield Adjustment (YA), Yield Endorsement (YE), and Trend Adjustment Endorsement (TA). Simply put, crop yield is the There are a variety of factors associated with crop yield and the risks involved with farming. yield meaning: 1. to supply or produce something positive such as a profit, an amount of food or information: 2…. The subjective methods, often used in developing countries, include the field reporting system, eye estimation, farmer interview and expert assessment. Crop yield is a measurement of the amount of agricultural production harvested—yield of a crop—per unit of land area. Yield potential is defined as the yield of a cultivar when grown in environments to which it is adapted, with nutrients and water non‐limiting and with pests, diseases, weeds, lodging, and other stresses effectively controlled. meThods for meAsurIng CroP ProduCTIon or YIeld under ConTInuouslY hArvesTed rooT CroPs 81 7.1. Here, we define yield potential as the yield of an adapted crop variety or hybrid when grown under favorable conditions This, in turn, led to the formation and growth of cities, which then translated into an increased demand for foodstuffs or other agricultural products. When more than four years of yields exist, yields used in determining guarantees and premiums for crop insurance typically are based on the insurable unit’s actual yields. In agriculture, the yield (also known as "agricultural productivity" or "agricultural output") is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. Crop Acreage and Yield Crop Acreage and Yields USDA produces charts and maps displaying crop yields, crop weather, micromaps, and crop acreage animations. • In desert areas grasses and shrubs are common where hot desert climate exists • Though the rainfall has major influence on yield of crops, yields are not always directly proportional to the amount of Precipitation as excess above optimum reduces the yields This was particularly important in the 1960s during the height of the Cold War, when the U.S. was using such methods to assess the agricultural health of China and the Soviet Union. 2. a the amount of such produce in any particular season. Today, foreign countries frequently publish similar crop yield statistics on their government websites, similar to what the USDA does in the U.S. 1 a : to bear or bring forth as a natural product especially as a result of cultivation the tree always yields good fruit. In most of the cases yield data are not recorded but obtained by dividing the production data by the data on area harvested. Crop, the term common in agricultural and commercial use, denotes the amount produced at one cutting or for one particular season: the potato crop. The unit by which the yield of a crop is measured is tonnes per hectare.. History. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. Historically speaking, a major increase in crop yield took place in the early eighteenth century with the end of the ancient, wasteful cycle of the three-course system of crop rotation whereby a third of the land lay fallow every year and hence taken out of human food, and animal feed, production. The U.S. Department of Agriculture (USDA) produces charts and maps displaying crop yields, crop weather, and crop acreage animations to help U.S. farmers maximize agricultural product output. Part of this information is the absolute high and low yield for the entire history of the data series, some of which extend back over 150 years. Advancements in farming techniques, utilization of fertilizers, and a robust economy are contributing factors to record crop production in recent years. The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. YA allows 60% of the T-yield to replace the actual yield, where the T-yield – or transitional yield – is specified by the R… In a global economy, crop yield data is vital to measure if American crops adequately provide enough food for our internal food supply, livestock, and energy sources. The U.S. Department of Agriculture provides monthly crop yield reports of 23 products ranging from rice to tobacco. Prior to 2018, the YC was automatic. The seed ratio is the ratio between the investment in seed versus the yield. [3], The amount of farm product produced per unit area for a given time. a crop of new publications. Economics is a branch of social science focused on the production, distribution, and consumption of goods and services. Choosing the right time to plant is often the most important part of … Definition of Crop production. For example, if a wheat producer counted 30 heads per foot squared, and each head contained 24 seeds, and assuming a 1,000-kernel weight of 35 grams, the crop yield estimate using the standard formula would be 30 x 24 x 35 x 0.04356 = 1,097 kg/acre. SCR is the abbreviation for the Seychellois rupee, the currency of the island nation of Seychelles in the Indian Ocean off East Africa. The more grain or fodder a farmer can produce, the more draft animals such as horses and oxen could be supported and harnessed for labour and production of manure. The yield gap (Yg) is the difference between Yp (irrigated crops), Yw (rainfed crops) or Ypi (partially- irrigated crops) and actual yield (Ya). For example, they publish a monthly report of field crop yields for 23 different products ranging from barley to rice to tobacco and wheat. Crop yield potential is mainly regulated by genetic characteristics, atmospheric CO2 concentration, temperature and solar radiation. This measure is more commonly used for legumes, grains or cereal. Crop yield is the measure most often used for cereal, grain, or legumes and typically is measured in bushels or pounds per acre in the U.S. As the human population soars well beyond 7 billion people, so does the demand for food. One of the metrics used to determine the efficiency of food production is crop yield. yield data alone are used to rate soils. Increased crop yields also means fewer hands are needed on farm, freeing them for industry and commerce.
