Factors Affecting Yield of Crops

Abstract

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 condition, soil fertility, topography, water quality, etc.). These factors account for yield differences from one region to another worldwide. The current chapter will discuss each of these three basic factors as well as providing some recommendations for overcoming them. In addition, it will provide the importance of climate-smart agriculture in the increase of crop yields while facilitating the achievement of crop production in safe environment. This goes in line with the second goal of 2030 Agenda for Sustainable Development of United Nations in transforming our world formulated as end hunger, achieve food security, improve nutrition and promote sustainable agriculture.

A Biostimulant Based on Seaweed (Ascophyllum nodosum and Laminaria digitata) and Yeast Extracts Mitigates Water Stress Effects on Tomato (Solanum lycopersicum L.)

“…In the past, in order to limit the negative effects of abiotic stresses, chemical fertilizers and other polluting formulations have been widely used as agriculture practices [7]. Despite their use positively affecting the growth and agricultural yields of plants grown under adverse environmental conditions, this approach has resulted in other problems, including the massive contamination of the soil and atmosphere [8]. Consequently, finding new eco-sustainable approaches aimed to help plants to counteract the negative effects deriving from the lack of water, without generating further environmental pollution, is one of the most important challenges for agricultural research [9].…”

Optimization of Newly Opened Rice Fields on Tidal Swamp Through Superior Rice Varieties in Bulungan District

“…Rice productivity was influenced by the interaction between genetics and environmental factors. Environmental factors that affect the productivity of newly opened rice fields were poor land management, inefficient water system, and low soil fertility rate (Liliane and Charles, 2020). Most of the rice superior varieties for swamp (Inpara) produced by the Agricultural Research and Development Agency from the Ministry of Agriculture are tolerant of ferro toxicity.…”

A Decision Support Framework for National Crop Production Planning

“…In this section, we explore different techniques for optimized crop production, challenges of crop production in Pakistan, and methodologies for sustainable agriculture. We have already summarized the climatic and non-climatic factors affecting crop from [13] in Fig. 1.…”

“…A detailed analysis for the gap between crop need and production is presented in [12]. The production of every crop varies area-wise due to the deviation in climatic and non-climatic factors in different regions [13]. These factors are financially constrained and variance in the financial condition affects the overall productivity.…”
