ABSTRACT

A field experiment was conducted at the dryland farm of S.V. Agricultural College, Tirupati during kharif, 2015 to study the effect of various organic sources viz., farm yard manure, poultry manure, sheep manure and neem cake along with recommended NPK through fertilizers on growth, yield attributes and yield of groundnut. Application of recommended dose of nutrients through fertilizers (20-40-50 kg N, P2 O5, and K2O ha-1) resulted in improved growth parameters, yield attributes and yield of groundnut. Among the various organic sources tested, supply of 100% N through FYM recorded significantly higher growth, yield attributes and yield, which was in parity with 50% N through FYM + 50% N through sheep manure. Application 50% N through poultry manure or sheep manure or neem cake in combination with 50% N through FYM recorded significantly higher pod yield compared to sole application of these manures.
