Crop yield research focuses on understanding and improving the quantity of crops produced per unit of land area over a specified period of time. This research area encompasses various factors such as genetics, soil quality, climate conditions, pest and disease management, irrigation, and agricultural practices that can influence crop productivity. The goal of crop yield research is to develop strategies and technologies that can increase agricultural productivity and ensure food security for growing populations. Researchers in this field may use a combination of field trials, modeling, genetic engineering, and data analysis to study and optimize crop yield.
