The highest yielding crops are sugar cane, sugar beet, and tomatoes. Sugar cane accounts for about 80% of the world’s sugar production, while sugar beet the remaining 20%.


How is agricultural yield calculated?

The total yield is calculated from the weight multiplied by the total acreage in production. Farmer estimation: Farmers are asked for their estimation of the total crop harvested. This value is divided by how much land they planted in order to estimate yield.


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 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.


Why are permanent crops not as reliable as temporary crops?

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.

How do agrarians increase crop yields?

Agrarians aiming to increase crop yields must take care of their plants throughout their development and up the end of the growing season. Depending on the problem that may arise, farmers use different substances to diminish the impact of weeds, pests or diseases on crop yield.


How does soil affect crop yield?

The quality of soil, i.e. its fertility, is one of the main factors that affect crop yields. Apart from agricultural productivity, the soil quality also influences the cost for a farmer to grow one or another plant, as some of them require certain ratios of specific elements in the soil, like mineral particles, organic matter, water, air, etc. To attain increased crop yields, farmers need to closely monitor soil conditions on their land plots. One of the best ways to maintain the soil in good health is to practice crop rotation, among others. Alternating plants on a given field plot prevents soil exhaustion and breaks pest cycles, which will result in better agricultural output and, therefore, will increase the average crop yield per acre.


Why do agrarians need to sow seeds?

Agricultural productivity depends on the quality of seeds with which farmers sow their fields. Therefore, in order to increase crop yield on their farmlands , agrarians are recommended to sow only certified seeds that have passed all the necessary quality controls.


Why is it important to monitor crop growth?

From the early stage of development through budding and up to harvesting, it is very important to monitor plant health in order to timely detect any problem that can arise on a given farmland (be it related to pest infestations, plant diseases, weeds, etc.) and that can affect the crop yield .


How to maintain soil health?

It is considered to be probably the most important measure of each farmer’s performance, as it embodies the result of all the efforts and resources invested by agrarians in the development of plants on their fields.


What are the challenges farmers face?

Weed control and pest management are the biggest challenges for farmers during the growing season. A single weed, for example, can generate over 10 million weed seeds, and if they are not managed in time, it can substantially decrease the yields on a given field and create problems for years to come.
