A field experiment was conducted at Cooch Behar, West Bengal during the Pre-Kharif seasons of 2008 and 2009 in a randomized complete block with twelve treatments to study the effect of organic sources of nutrients on physiological characters, yield attributes and pod yield of groundnut (Arachis hypogaea L.). The results showed that groundnut can be organically produced, provided adequate phosphorus is applied as phosphocompost. The highest yield of groundnut obtained with combination of phosphocompost, poultry manure, neem cake and vermicompost. FYM, vermicompost, neem cake and poultry manure applied alone was not able to adequately supply plant nutrients specially phosphorus and gave low yield of groundnut. Net photosynthesis rate recorded the highest correlation coefficient (0.948) with pod yield of groundnut.References
