Crop production and yield limiting factors

Abstract

Global warming has seriously affected human survival and the sustainable development of agriculture. Due to the rapid global climate change, the situation has further deteriorated. In crop production, drought is undoubtedly the most important stress, which has a great impact on crop growth and productivity. Understanding the physiological, biochemical and ecological interventions associated with these stresses is important for better management. Abiotic stress is one of the main factors restricting crop production and food security in the world. This paper discusses the scientific basis of greenhouse gas emission and carbon absorption in farmland describes the response of plants to drought stress and the negative effects of crop growth and yield formation and evaluates the gap between actual yield and crop potential yield and the influence of limiting factors, which has not been reasonably eliminated. This phenomenon is common in the agricultural production of all countries in the world.
