What is the yield per hectare?
Crop yield is a measurement of the amount of agricultural production harvested per unit of land area. Crop yield is the measure most often used for cereal, grain or legumes and is normally measured in bushels or pounds per acre in the U.S. (metric ton or kilogram per hectare outside the U.S.).
How do you calculate average yield per hectare?
To calculate the indicator’s value, sum up the entire weight of the harvest and divide it by the total size of land. For example, 4,500 tons of rice divided by 1,500 hectares = yield of 3 tons per hectare.
What is the method and formula used to calculate portion yields?
The formula is EP weight ÷ AP weight × 100 = yield %. Yield percentage is important because it tells you several things: how much usable product you will have after processing; how much raw product to actually order; and the actual cost of the product per dollar spent.
How do you calculate vegetable yield?
To estimate yield in a consistent manner, one can harvest 10′ of row at several locations in the field. Multiply the average yield (lb) per 10′ of row times the following row spacing factors to convert the sample yields to lb/A.
What is production yield calculation formula?
Yield = the number of non-defective items / the number of manufactured items. In addition, thinking of yield in terms of materials, it refers to the raw material productivity, which is expressed by the formula: Raw material productivity = production quantity / raw material’s amount used.
How yield is measured for a piece of land?
During a single season, the yield is measured as a crop produced on a given piece of land. Kilogram per hectare or bushels per acre are the units by which the yield of a crop is usually measured now – a – days. The surplus crops which are beyond the needs of the subsistence agriculture can be sold or bartered.

How has crop yield increased over the past decades?
Crop yields and farm efficiency have increased dramatically over the past decades as technology has advanced in farm automation, crop genetics, fertilizers, and pesticides.
Why is crop yield important?
In a global economy, crop yield data is vital to measure if crops that are produced can adequately provide enough food for a nation’s food supply, livestock feed, and energy sources.
When was the absolute low crop yield?
Interestingly, for many products, the absolute low crop yield occurred in the 1930s during the time of the Great Depression and Dust Bowl years, while the absolute high crop yield occurred in the most recent years recorded. 2.
How accurate is yield estimate?
Accuracy of yield estimates depends upon an adequate number of counts being taken so as to get a representative average of the paddock. The yield estimate determined will only be a guide and assumptions made from the estimates contain a degree of uncertainty.
Why is it important to estimate grain yield?
Accurate, early estimation of grain yield is an important skill. Farmers require accurate yield estimates for a number of reasons: Extensive personal experience is essential for estimating yield at early stages of growth. As crops near maturity, it becomes easier to estimate yield with greater accuracy.
When are yield calculators appropriate?
As for the timing, Park said, “yield calculators are appropriate at any point when you’re forced to ask that hard question ‘do I spend more money?’ You don’t want a visual guesstimate at that point in time. You need hard numbers.

Park said all the formulas have been ground truthed repeatedly and fine-tuned according to combine results. If the growing season continues without disaster, the yield calculator is close to the harvest reality.
What is crop yield?
The definition for ‘ crop yield ‘ given by the FAO is ‘Harvested production per unit of harvested area for crop products. In most of the cases yield data are not recorded but obtained by dividing the production data by the data on area harvested. Data on yields of permanent crops are not as reliable as those for temporary crops either because most of the area information may correspond to planted area, as for grapes, or because of the scarcity and unreliability of the area figures reported by the countries, as for example for cocoa and coffee.’ 4
What is yield gap?
Yield gaps are defined as the different between the actual crop yield and the attainable yield.
What is the main driver of cereal production?
Although there are a few exceptions–notably across Sub-Saharan Africa, the continued increase in cereal yields across the world has been the major driver of total cereal production. This has inevitably allowed us to ‘spare’ land we would have otherwise had to convert for cereal production.
How much land was used for cereal production in 2014?
However, if global average cereal yields were to have remained at their 1961 levels, we see the amount of additional land (in blue) which we would have had to convert to arable land if we were to achieve the same levels of cereal production. This ‘spared’ land amounts to 1.26 billion hectares in 2014– roughly equal to the area of Mexico and Europe combined.
How much has the average cereal yield increased since 1961?
Most of our improvements in cereal production have arisen from improvements in yield. The average cereal yield has increased by 175 percent since 1961.
What is the trade-off between land use for agriculture and yields?
This trade-off between land use for agriculture and yields is very clearly exemplified in a comparison between cereal production in Asia and Sub-Saharan Africa. Expansion of cereal production has followed very different paths in Sub-Saharan Africa and Asia.#N#Land use for cereal production in South Asia has increased by less than 20 percent since 1961, meanwhile cereal yields have more than tripled – which meant that much more food could be produced in South Asia without an equivalent extension of the agricultural land. This is in strong contrast to Sub-Saharan Africa where the area of land used for cereal production has more than doubled since 1961 and yields have only increased by 80 percent.#N#Click to open interactive version
Which countries have seen a much larger increase in cereal yields relative to area used for production?
Most European, American (both North and Latin American), Asian and Pacific countries have seen a much larger increase in cereal yields relative to area used for production. For many, changes in the arable land have been minimal (or have declined). This is an important contrast to Africa where results are more mixed.
What Is Crop Yield?
How Crop Yield Works
To estimate crop yield, producers usually count the amount of a given crop harvested in a sample area. Then the harvested crop is weighed, and the crop yield of the entire field is extrapolated from the sample. For example, if a wheat producer counted 30 heads per foot squared, and each head contained 24 seeds, assuming a 1,000-kernel weight of 35 …
