Evaluation of Integrated Nutrient Management Practices on Growth, Yield and Economics of Green Chilli cv Pusa Jwala (Capsicum annuumL.)

Abstract

The present study was carried out during 2007 and 2008 rabi season at Agricultural Research Institute, Rajendranagar, Hyderabad, Telangana state, India. with 9 treatment combinations (Recommended dose of inorganic fertilizer (200-60-80 kg NPK ha−1), 150% of RDNF, 200% of RDNF, 250% of RDNF, Complete organic N through FYM (25%) and neem cake (25%) as basal and vermicompost as top dressing (50%), 50% organic+50% RDNF, 75% organic+75% RDNF, 100% organic+100% RDNF, 125% organic+125% RDNF) in randomize block design with 3 replications. Combined application of 150 kg N ha−1 along with 10 t FYM and 0.5 t neem cake ha−1 showed significant increase in plant height (59, 58 cm), canopy spread (40.7, 42.1 cm), number of branches plant−1 (23, 23), number of fruits plant−1 (194, 164), yield plant−1 (410, 315 g) and total green chilli yield of 13306 and 10550 kg ha−1 respectively. But number of fruits plant−1, yield plant−1 and total yield ha−1 were on par with combined application of 100 and 125% organic manures and inorganic fertilizers each, respectively. However in terms of benefit cost ratio combined application of 150 kg N ha−1 along with 10 t FYM and 0.5 t neem cake was economical with highest net returns ( 79923 and 52369 ha−1) and B: C (2.5 and 1.99). Significantly the lowest growth, yield attributes and fruit yield (1924 and 3577 kg ha−1) of green chilli with negative net returns ( 45063 and 28537 ha−1) and lower B C (0.3 and 0.56) was noticed in complete organic manure application.
