What are the 3 major factors affecting yield of agricultural crops?

These factors are grouped in three basic categories known as technological (agricultural practices, managerial decision, etc.), biological (diseases, insects, pests, weeds) and environmental (climatic condition, soil fertility, topography, water quality, etc.).

How much food will we have to produce by 2050?

According to estimates compiled by the Food and Agriculture Organization (FAO), by 2050 we will need to produce 60 per cent more food to feed a world population of 9.3 billion.

What are some factors that affect the yield in agriculture?

Yield is influenced by climate and temperature, plant and water management, and soil nutrient management factors. Good genetics plus the ability to manipulate and optimize the plant’s environment generally result in the highest yields. Climate and temperature factors are critical to achieving high yields.

What is yield per acre?

Crop yield is the term for the amount of harvested production per unit of land. In the U.S., crop yield for grain and oilseed crops is typically measured in bushels per acre. Acre– unit of land used to measure cropland in the U.S. An acre is 4,840 square yards, and there are 640 acres in one square mile.

What factors affect yield?

The yield and rate of a chemical reaction depend on conditions such as temperature and pressure. In industry, chemical engineers design processes that maximise the yield and the rate at which the product is produced. They also aim to reduce waste and energy costs at all stages of the process.

What are yields in agriculture?

Crop yield is a standard measurement of the amount of agricultural production harvested—yield of a crop—per unit of land area. Crop yield is the measure most often used for cereal, grain, or legumes; and typically is measured in bushels, tons, or pounds per acre in the U.S.

What is the estimated population of the world by 2050?

9.9 billion
The 2020 World Population Data Sheet indicates that world population is projected to increase from 7.8 billion in 2020 to 9.9 billion by 2050. This level represents an increase of more than 25\% from 2020.

How is farm yield measured?

Measurement. The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Agricultural productivity is measured in money produced per unit of land, but yields are measured in the weight of the crop produced per unit of land.

How does increasing cereal yield affect agricultural land area?

Increasing yields reduces the pressure of expanding agricultural land. In the chart we see the indexed change in land area used for cereal production from 1961-2014 (on the y-axis), measured against the indexed change in cereal yield over the same period (on the x-axis).

What is the definition of crop yield in agriculture?

Definitions 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.

What is the second most important cereal crop after maize?

Sorghum is the second most important cereal after maize with 22\% of total cereal area. Pearl millet is a climate hardy crop which is grown in harsh conditions, but as a subsistence crop. Harvested from an area of 20 m ha in the semi-arid regions of Africa pearl millet contributes 19\% area to cereal production.

How much arable land is needed to produce the same crop?

For example, globally in 2014, the index value was 0.3; this means only 30\% of the arable land area was needed to produce the same quantity of crops relative to 1961. 70\% less land was needed. This data can be viewed for other countries and regions by selecting ‘ Add country ’ on the chart.
