How has the agricultural yield increased in our country


Crop yields, farm efficiency, and agricultural product output in the U.S. have increased dramatically over the past decades as technology has advanced in farm automation, crop genetics, fertilizers, and pesticides. Crop yield data is important not only in the U.S. but abroad as well.

There are a number of factors which are likely to have contributed to sustained yield gains: fertilizer application, irrigation, increased soil tillage, and improved farming practices.


How can we increase agricultural yield at a sustainable level?

Maintaining agricultural yield at a sustainable level requires that the regenerative capacity of driving subsystems is sufficiently strong despite fragmentation. Practices adopted for increasing agricultural yield have turned out to be neither economically nor environmentally sustainable.

Why has agricultural production increased in the United States?

The value of agricultural production in the United States rose over most of the last decade due to increases in production as well as higher prices. Yield gains for crops were particularly important, although acreage also rose in response to elevated prices from 2008 to 2012.

What factors affect the average crop yield per acre?

The average crop yield per acre on a given field is very much conditioned by weather factors. With the same quality of soil and the same species of seeds planted, the climate conditions have a predominant influence on the development of plants and, consequently, on yields.

Which countries have increased the yield of cereal crops?

Some countries, including Ethiopia, Nigeria and Algeria have followed the rest of the world in yield increases. However, a failure to increase agricultural productivity in many Sub-Saharan countries has led to large increases in land used for cereal production.

What are the development of agriculture in the Philippines?

Through commercial agriculture and improved infrastructure, small-holder farmers can increase their incomes and slowly become more self-reliant. Developing irrigation systems in rural farming lands which is an important aspect of the project, makes farming more efficient for the people of the Philippines.

What is increased yield?

Increased crop yields also means fewer hands are needed on farm, freeing them for industry and commerce. This, in turn, led to the formation and growth of cities, which then translated into an increased demand for foodstuffs or other agricultural products.

What does yield mean 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.

How much did aggregate input use increase in the 1980s?

Although the use of labor and land in agriculture declined between 1948 and 1980, aggregate input use increased at an average rate of 0.7 percent per year due to dramatic increases in intermediate goods and capital use.

What was the average real interest rate in 1981?

The average real interest rate rose to nearly 16 percent in 1981-83 and remained high until the 2000s. This mix of fiscal stimulus and monetary restraint slowed the growth in U.S. agricultural exports and discouraged capital investment during this period.

Why do farmers use machinery?

Farmers now use machinery and agricultural chemicals more intensively than in the past, largely in response to rising costs for labor and land. Increases in these other inputs are also part of the reason that land productivity and labor productivity have grown dramatically over the last six decades. Embed this chart.

What contributed to the lower opportunity cost of invested capital?

In addition, declining interest rates and rising inflation contributed to a lower opportunity cost of invested capital. However, in the early 1980s, restrictive monetary policy by the Federal Reserve pushed up interest rates and the dollar appreciated on foreign exchange markets.

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?

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 is the agrarian performance important?

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.

Reductions in the canopy and litter layer also increase the energy associated with raindrops as they hit the soil surface, or as water moves across soil, increasing the potential for soil crusting and erosion ( Chapin et al., 2011 ).

How can anaerobic microbes cope with changing soil moisture conditions?

For example, over short time scales, facultative anaerobic microbes can cope with changing soil moisture conditions by switching from aerobic respiration when oxygen is available to anaerobic metabolisms such as denitrification when oxygen becomes limiting ( Zumft, 1997).

In the 50 years since, he has taken on considerably more responsibility and now feeds 155. 50 years of change mean farmers can produce more food and fiber on fewer acres and with fewer nutrient inputs.

Why is the advancement from one farmer feeding 25 people to 155 in 50 years a significant achievement?

“And we are doing it with far fewer farmers. The reason we have food on our table is because of the exponential growth from increased productivity.”

The Future of TFP Growth: Public R&D Scenarios and TFP Projections

  • The major driver of longrun TFP growth is R&D. If public R&D has slowed, then why has there been no slowdown in U.S. agricultural productivity? One possible explanation is that there is often a long lag between when a research investment is made and when the product of that research is applied to farm production and starts to boost productivity. Many studies show that it is the acc…
