To investigate the impact of in-situ moisture conservation practices and nitrogen fertilization practices on growth analysis and productivity of pigeonpea, a field investigation was carried out at Gunegal Research Farm, Central Research Institute for Dryland Agriculture, Hyderabad, during kharif 2022–23 and 2023–24.
During kharif seasons of 2022–23 and 2023–24, field experiments were carried out for two consecutive years at ICAR-Central Research Institute for Dryland Agriculture to evaluate the impact of in-situ moisture conservation practices and different levels of nitrogen on growth and productivity of pigeonpea under rainfed Alfisols of semi-arid tropics. The study was conducted in split-plot design with four different in situ moisture conservation practices as in main plots and four nitrogen levels as in subplots.
The pooled data of the study showed that in-situ moisture conservation practices recorded higher yield due to improve growth and physiological indices of the crop because of better moisture availability to the plant. The increase in nitrogen application increased in yield. This increase in yield with nitrogen levels is attributed to higher nitrogen availability which helped in improvement in growth, physiological growth and crop productivity.
