Response of Sunnhemp (Crotalaria juncea L.) to Spacing and Nutrient Management Under South Gujarat Condition

A field experiment was conducted during rabi season of the year 2010–2011 at College Farm, Navsari Agricultural University, Navsari (Gujarat) to study “Response of sunnhemp (Crotalaria juncea L.) to spacing and nutrient management under South Gujarat condition”. Sixteen treatment combinations consisting of two levels of spacing, 45 cm x 10 cm and 60 cm x 10 cm, two levels of inorganic fertilizers; 75 per cent RDFand 100 per cent RDF, and four levels of biofertilizer, no biofertilizer, Rhizobium (Azorhizobium caulinodans), Phosphate solubilizing bacteria (Bacillus coagulans) and combination of Rhizobium (Azorhizobium caulinodans) + Phosphate solubilizing bacteria (Bacillus coagulans) were evaluated in split-split plot design with three replications. The results revealed that rabi sunnhemp grown for seed production at 60 cm × 10 cm spacing and fertilized with 100 per cent RDF (25: 50: 00 NPK/ha) along with seed inoculation with Rhizobium (Azorhizobium caulinodans) @ 10 ml/kg seed + phosphate solubilizing bacteria (Bacillus coagulanns) @ 10 ml/kg under South Gujarat condition gave higher yield and monetary returns.
