tailieunhanh - Growth and yield responses of soybean under rainfed condition in selected districts of Madhya Pradesh, India

This study is aimed at assessing the impact of rainfall distribution pattern on the growth and yield of soybean crop in selected districts of Madhya Pradesh. The crop growth is found to be more sensitive to rainfall pattern at critical stages. Prolonged dry spells at critical life stages of the soybean crop are found to adversely affect crop development and growth and hence the yields at selected sites. Rainfall and yield data of selected districts of Madhya Pradesh were collected and analysed for the period of 11 years (2004-2014). Stage wise yield reduction of soybean due to less amount of rainfall at critical stages was determined. Crop water requirement of soybean was determined through CROPWAT software for selected districts. Our findings show that, repeatedly low rainfall at vegetative stage resulting yield reduction in almost all selected districts of MP. Deficient rainfall during the growing season at critical stages could be a crucial factor for the soybean productivity. | Growth and yield responses of soybean under rainfed condition in selected districts of Madhya Pradesh, India
