Crop produce can be increased by increasing the land under cultivation, by improvement in the methods of agriculture, and by developing better varieties of crops by plant breeding. Hybridization is a technique used for plant breeding in which new varieties with desired characteristics of high yield and resistance to disease, are developed. Soil organic matter and clay particles hold large stores of plant nutrients. These reservoirs, however, are not all available to the crop. In an organic crop rotation, the grower manages soil organic matter and nutrient availability by incorporating different crop residues, cycling among crops with different nutrient needs, using cover crops, and adding organic soil amendments.
Recently, Italian researchers published a review of studies concluding planting genetically modified (GM) maize (corn) over the past 20 years has increased the agricultural yield of this popular and important staple food. In this context, it is important to remember one of the most popular myths perpetuated about GM crops: that they aren’t boosting yields. Here, we undertake a review of factors that limit yield in rainfed environments and discuss genetic opportunities and genetic progress in overcoming them. The examples given are for wheat (Triticum aestivum L.), but the principles apply to all cereal crops grown in dry environments.
The required increase in agricultural productivity required by may be in the range of 60–% as compared with the levels of (Ort et al., ). A rapid increase in crop yield, especially for cereals, was obtained in the second half of the 20 th century during the so-called ‘Green Revolution’.

Furthermore, approximately 14 million people are engaged in the production of oilseed crops and another 1 million in the processing of these crops. Despite the fact that India holds the premier position in the world in respect of gross cropped area, its productivity is the lowest. Yields can also increase, as the anaerobic digestion process increases the plant availability of N in digestate used as fertiliser.
In the future, there will be new opportunities for increasing yields through more intensive machine use without increasing GHG emissions, by a transition to electric machinery in combination with renewable by: Lastly, a sharp downturn in the global economy could restrict demand for both meat and fuel in ways that reduce the economic incentive to increase crop yields.
The combination of marker-assisted breeding, biotechnology traits, and continued advances in agronomic practices has the potential to double corn yields in the United States over the next two decades (Fig. 7).Cited by: Republic of Kosovo New Opportunities in Agriculture. Overview: New Opportunities in Agriculture (NOA), a five-year program funded by USAID under the RAISE PLUS IQC, boosted production by capitalizing on the strengths of traditional crops, introducing new high-value crops into the market; involving women, youth, and minorities in the production process; and advancing and expanding.
Increased yields in organic crop production also mean an increased amount of crop residues and thus increased carbon sequestration in the soil – positive for both soil fertility and climate. More effective weed control increases the yield, but can affect biodiversity in fields negatively – a decrease in flowering herbs may adversely affect.
About this book This is an invaluable reference book on the opportunities for crop yield increase to feed the world to Written by three world-renowned agricultural scientists, it is aimed at agricultural scientists and economists, decision-makers in the food production industry, concerned citizens and tertiary students.
Crop Production and Management Class 8 Science Chapter 1. Crop Production and Management Class 8 Science Chapter 1 as per NCERT Book used in CBSE and other Schools. The lesson covers the complete explanation of class 8 Chapter 1 Crop production and covered are crops, types of crops, agricultural practices and implements used for farming.
Findings from the book indicate: No-till farming alone could increase maize yields by 20 percent, but also irrigating the same no-till fields could increase maize yields by 67 percent in Nitrogen-use efficiency could increase rice crop yields by 22 percent, but irrigation increased the yields by another 21 percent.
Increasing the production of crops per area of land is of key importance for food security, living standards, and decreasing humanity’s impact on the environment. Several studies have shown that global crop production needs to double by to meet the projected demands from rising population, diet shifts, and increasing biofuels consumption.
Boosting crop yields to meet these rising demands, rather than clearing more land for agriculture has been highlighted as a preferred solution to meet this goal. However, we first need to understand how crop Cited by: Crop production is a branch of agriculture that deals with growing crops for use as food and fiber.
Degree programs in crop production are available at undergraduate and graduate levels. This is an invaluable reference book on the opportunities for crop yield increase to feed the world to Written by three world-renowned agricultural scientists, it is aimed at agricultural scientists and economists, decision-makers in the food production industry, concerned citizens and tertiary students.
Global yields of major crops are analysed using climate, irrigation and new nutrient data to show that large production increases are possible from closing yield gaps to % of attainable yields Cited by: The goal of the global agribusiness value chain, which spans input companies through to the final consumer1 and has a total value of around US$5 trillion, is to provide sustainable access to affordable food, feed, fibre and, more recently, fuel.
However, this goal is getting harder to achieve every year due toFile Size: 2MB.

The researchers studied yields of four key staple crops – maize, rice, wheat and soybeans – and found they were increasing by only about % to % a year.
Other factors such as weather, fertility status, and the ability of a hybrid to handle stress may be limiting factors in low-yield environments. Crop-production factors interact with each other. A high-yield environment may experience greater opportunities for disease, but yield increases are observed in the absence of disease also.
: Gene Johnston. Cover Crops and Crop Rotation. Cover crops, when used with a simple crop rotation strategy, have been reported to increase overall yields and, in particular, to increase the crop yields of c orn and soybeans while boosting field health over time.
There are a variety of cover crops available to suit the needs of any situation.
