Crop-weather relationship of soybean in Marathwada region of Maharashtra

Soil moisture levels also significantly impact soybean growth and yield, affecting nutrient uptake, root development, and overall plant health. [...]an attempt has been made to understand the intricate relationship between weather parameters during different phases of the soybean crop and its yield using long-term experiments conducted as Parbhani, Maharashtra. Influence of weather parameters on soybean yield The correlation analysis worked out between grain yield and weather parameters during different phases of soybean using 8 years data (2013-2020) shows the differential effect of various weather parameters during different growth stages on soybean yield (Table 2). Development of prediction equation Multiple linear regression models were developed to predict the grain yield of soybean at different stages of crop growth, with grain yield as the dependent variable and weather parameters occurring at various growth phases as independent variables (Table 3). Elevated temperatures above a threshold value during the flowering to pod formation period can significantly reduce yield by adversely affecting subsequent reproductive processes (Wheeler et al., 1996).
