Crop yield

In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer, the creation of better farming tools, and new methods of farming and improved crop varieties have improved yields. The higher the yield and more intensive use of the farmland, the higher the productivity and profitability of a farm; this increases the well-being of farming families. Surplus crops beyond the needs of subsistence agriculture can be sold or bartered. The more grain or fodder a farmer can produce, the more draft animals such as horses and oxen could be supported and harnessed for labour and production of manure. 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.

• Crop Yield - an overview | ScienceDirect Topics

  Crop yield potential is defined as the crop yield obtained when a crop is grown without limits on water or nutrients and in the absence of any pests, diseases, and weeds. Therefore, a crop’s yield potential is a function of solar radiation, air temperature, and crop genetics at a specific location (van Ittersum et al., 2003). In rain-fed environments (agricultural environments that must rely on rainfall for water), the potential yield concept is adjusted to a water-limited yield potential [...] The crop yield is an important determinant of how efficiently water is used. We had an objective to develop efficient and high-yielding varieties of crops: An enormous effort has been expended on this objective. Impressive results have been achieved in a few crops only. For major crops high-yielding varieties are yet to come which should have a high response to applied fertilizers and should efficiently use the other inputs including water. The quantum jump with respect to all these is yet to [...] sensing-based crop yield models need to have certain crop yield statistics (e.g., 1.10 t/ha for corn) for model calibration. Such crop yield statistics are not always available to the general public, especially at field-level scales. One exception is Lobell et al. (2015), who predicted yields for more than 17,000 corn and 11,000 soybean fields in the Midwestern United States, using multitemporal (2008–13) Landsat data from all Landsat 5 and Landsat 7 imagery for primary inputs for their crop

• Key Farming Problems Affecting Crop Yield and Ways to Improve

  Improving crop yield is a multifaceted challenge that requires integrating traditional knowledge with modern technological advancements to address the global environmental challenges facing the industry. By addressing the key factors affecting crop production and implementing agricultural improvements, it is possible to achieve higher yields, better quality crops, and more sustainable farming practices without compromise. [...] Crop production is a complex process influenced by numerous environmental, biological, and human-related factors. Understanding the factors affecting plant growth is essential for farmers, agronomists, and policymakers to make informed decisions that lead to sustainable and efficient agricultural practices. This article aims to shed light on the current farming issues affecting low crop yield, as well as a variety of strategies and crop development in agricultural practices aimed at mitigating [...] ## 4 Ways to Improve Crop Yields For improvement in crop yields, it’s important to understand a blend of innovative and traditional methods. These ways lead to more sustainable agricultural practices and crop production. ### 1. Sustainable Farming Practices

• Crop yields have increased dramatically in recent decades, but ...

  The chart below shows the actual change in crop yields globally over this period. Wheat yields have grown by 225%, maize by 196%, soybean by 153%, and rice by 146%. This growth has been driven by improvements in seed varieties, fertilizers, pesticides, irrigation, and better farming practices. [...] In 2010, average maize yields were 5.2 tonnes per hectare — 47% higher than the 3.5 tonnes you’d get in 1981. If there had been no climate change, we might have achieved 5.4 tonnes instead. A gain of 0.2 tonnes per hectare. Soybean increased from 1.75 to 2.6 tonnes per hectare. Without climate change, that might have been 2.7 tonnes. The net impacts on rice and wheat have been marginal because reductions due to warming have been offset by CO 2 fertilization. [...] The study found that rice and wheat did not show a significant decline (and in some cases saw a small positive impact), but maize yields were 2.4% to 4.1%, and soybeans were 4.5% lower. 14

• Improving crop yield potential: Underlying biological processes and ...

  The future requirements for our crops are undeniably diverse and highly demanding. In the coming decades, one of humanity's greatest challenges will be to sustainably improve crop nutritional quality (Scharff et al.,2021) and yield. Here, yield refers to the total amount of crop biomass produced per unit area per year (Zhu et al.,2010). Increasing yield will depend on selecting the best traits, technologies and crops for breeding and crop management of plants, targeting sustainable increases in [...] plant organ growth and development. To go further, crop yield _potential_ is defined here as yield in the absence of limitations by input, disease or suboptimal growing conditions. The conversion of radiation to dry matter (radiation use efficiency or RUE) and the partitioning of acquired resources can be closely related to yield potential in these conditions. Hence our selection of sub‐traits is based on this principle. Future perspectives are presented for each of these areas. [...] Options to improve crop productivity by improving crop yield potential. Crop yield potential can be improved via single process (green) optimisation, macro‐process (blue) optimisation or a whole plant improvement (e.g. by integrating the optimisation of multiple processes in parallel, such as photosynthesis and leaf longevity). N = nitrogen, C = carbon. The mapping of the options to improve crop yield potential was performed within the CropBooster‐P project ( (Baekelandt et al.,2022; Harbinson

• Factors Affecting Yield of Crops - IntechOpen

  A good understanding of dynamics involved in food production is critical for the improvement of food security. It has been demonstrated that an increase in crop yields significantly reduces poverty. Yield, the mass of harvest crop product in a specific area, is influenced by several factors. These factors are grouped in three basic categories known as technological (agricultural practices, managerial decision, etc.), biological (diseases, insects, pests, weeds) and environmental (climatic
