SCR is the abbreviation for the Seychellois rupee, the currency of the island nation of Seychelles in the Indian Ocean off East Africa. The National Commodity Crop Productivity Index (NCCPI) model is a national soil interpretation that is not intended to replace other crop production models developed by individual states. 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. It is concluded that even though the principal cereal crops appear to be approaching the upper limit of harvest index, and future yield gains will have to be sought by increased biomass production, there will still be a need for the concept of harvest index as a tool in interpreting crop response to different environments and climatic change. By Yared Ashenafi Bayissa. The timeliness in producing these estimates is a vast improvement over the present assessment capability at the county level. The crop production index (PIN) is the sum of crop commodities produced (after deductions of quantities used as seed and feed). 4 [3], The amount of farm product produced per unit area for a given time. Agricultural credit is special credit advanced to farmers, agricultural producers, and others to finance agricultural transactions. In irrigated systems, yield potential or potential yield (Yp) is the yield of a crop cultivar when grown with water and nutrients non-limiting and biotic stress effectively controlled … Crop Acreage and Yield Crop Acreage and Yields USDA produces charts and maps displaying crop yields, crop weather, micromaps, and crop acreage animations.

Simply put, crop yield is the Each crop has a potential yield value that a farmer can compare his output to. Crop index definition is - the number that expresses the relative yield of the crops on a particular area with the average yield over an entire region being taken as 100. Surplus crops beyond the needs of subsistence agriculture can be sold or bartered. This, in turn, led to the formation and growth of cities, which then translated into an increased demand for foodstuffs or other agricultural products. Advancements in farming techniques, utilization of fertilizers, and a robust economy are contributing factors to record crop production in recent years. Sample sizes of a harvested crop are measured to determine the estimated crop yield. The unit by which the yield of a crop is measured is tonnes per hectare.. History.

When weeds were controlled with herbicide, no effects of crop density or spatial uniformity on crop biomass or yield were observed. In other words, net harvested production computed as harvested acres times net harvested yield. ABSTRACT- Harvest index (HI), ratio of seed yield to aboveground dry matter, is a very important parameter for estimating seed yield in several crop models. Thus, yield is a major decision-making tool used both by companies and investors. NASS publications cover a wide range of subjects, from traditional crops, such as corn and wheat, to specialties, such as mushrooms and flowers; from calves born to hogs slaughtered; from agricultural prices to land in farms.

The idea for this chart is taken from Ausubel, Wernick, and Waggoner (2013). Production: The total quantity of an agricultural commodity recovered or removed from the field. The ultimate goal of the thesis is to examine whether the NDVI model can produce accurate and timely yield forecasts. Book Developing an Impact-Based Combined Drought Index for Monitoring Crop Yield Anomalies in the Upper Blue Nile Basin, Ethiopia. Sometimes crop yield is referred to as "agricultural output.". The traditional calculation of yield is often employed on the final inspection step of a process to measure the effectiveness of the overall process. Plant Early, Plant Effectively. Incorporating MODIS derived phenology metrics improved model performance. For example, if three grains are harvested for each grain seeded, the resulting seed ratio is 1:3,[citation needed] which is considered by some agronomists as the minimum required to sustain human life. Agribusiness is the business sector encompassing farming and farming-related commercial activities.
