IRRIGATION AND INTEGRATED NUTRIENT MANAGEMENT IN CASTOR (RICINUS COMMUNIS L.)
Keywords:
Seed, yield , plant , castor, irrigationAbstract
         The results of a two year's field experiment conducted at Junagadh (Gujarat) on clayey soils to evaluate the effect of irrigation (0.4 and 0.8 IW:CPE), biofertilizer (control and seed treatment with Pseudomonas striata), nitrogen (50, 75 and 100 kg N/ha) and phosphorus (0, 25 and 50 kg P2O5/ha) revealed that irrigation scheduled at 0.8 IW:CPE, seed inoculation with phosphate solubilizing bacteria, application of 100 kg N/ha and 50 kg P2O5/ha significantly increased growth and yield attributes, and yield of castor as well as also proved economical in terms of net realization..
