Abstract

Field experimetns were conducted during summer (February-May) and kharif (June-September) seasons of 1996 and 1997 at Agricultural Research Station, Aliyarnagar, Tamil Nadu Agricultural University, India to study the influence of integrated management of irrigation, composted coirpith and nutrient on the physiological parameters and yield of soybean. Results revealed that frequent irrigation (0.90 IW/ CPE) with composted coirpith and split application of N,P and K with nutrient mixture spray maintained higher relative leaf water content and transpiration rate. This treatment has also significantly increased the seed yield of soybean.
