Abstract:
A field experiment was carried out at Department of Agronomy, Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri (Maharashtra) during Rabi seasons of 2004 on lateritic soil, comprising thirteen treatment combinations where four sources of manures i.e. FYM, poultry manure, vermicompost and goat manure and three levels of manures i.e. @ 2.5, 5.0, 7.5 t ha^-1 were applied, with one absolute control. The data revealed that application of manures through appropriate source and adequate levels to cowpea (Var. Konkan Sadabahar) is essential for enhancing grain yield, nutrient uptake, physico-chemical properties of soil as well as availability of macro-nutrients over absolute control. For this purpose, application of poultry manure was observed to be superior source as compared to FYM, vermicompost and goat manure; whereas in case of levels, application of manures @7.5 t ha^-1 to cowpea was found to be more effective than their lower levels and rest of the treatment combinations.
