Abstract

Field experiments were conducted on niger cv.GA.10 (Deomali) in red sandy to clay loam soils of RRTTS, Semiliguda, Koraput (Odisha) during kharif seasons of 2008, 2009 & 2010 to find out suitable combination of soil and foliar application of nutrients (urea and di-ammonium phosphate) for maximizing growth and seed yield. Nine treatments consisting with different nutrient management were tested in randomized block design with three replications. The results revealed that, foliar applications of Urea and DAP gave better performance regarding growth and yield attributes. Highest seed yield (417.2 kg/ha), net monetary return (Rs. 4247.00/ha) and benefit-cost ratio (1.51), recorded with application of 100% RDF + foliar application of 2% Urea twice at flowering and capitula formation stage (T₄) followed by T₅ (RDF + foliar spraying of 2% DAP twice at flowering and capitula formation stage) i.e. seed yield 387.7 kg/ha, net monetary return Rs. 3277.00/ha and benefit-cost ratio 1.39.
