Agronomic Investigations in Transplanted Pigeonpea cajanus cajan l Millsp Under Irrigation

Abstract

newlinePigeonpea being an important pulse crop of nutritional and economic significance, newlinefield experiments on Agronomic investigations in transplanted pigeonpea [Cajanus newlinecajan (L.) Millsp.] under irrigation comprising of spacing, foliar nutrition, levels and time newlineof application of nutrients were carried out at KVK Raddewadagi, Kalaburgi district, newlineUniversity of Agricultural Sciences, Raichur, Karnataka during kharif 2013-14 and 2014-15 newlineusing split plot design with three replications on Vertisols under semi arid environment. With newlinethe hypothesis that transplanting requires different spacing and foliar fortification for greater newlinecrop potential, three spacings 1.8 m x 0.6 m, 1.8 m x 0.9 m and 1.8 m x 1.2 m as main plot newlinetreatments and three foliar application of macronutrients viz., control (no foliar spray), foliar newlinespray of 19:19:19 and 13:0:45 of NPK each at 0.4 % at flowering and pod development as newlinesubplot treatments were evaluated. Planting geometry of 1.8 m x 0.6 m along with foliar newlinespray of 19:19:19 NPK at 0.4 % at flowering and pod development stages recorded newlinesignificantly higher seed yield (2764 kg ha-1), Gross and net returns followed similar trend. newlineSimilarly, study comprising five levels of fertilizer RDF (25:50:0 N:P2O5:K2O kg ha-1), 125, newline150, 175 and 200 % RDF as main plot treatments and three time of application of fertilizers, newlineall as basal dose, 25% of RDF as basal dose; 50% of RDF at 30 DAT and 25 % of RDF at 60 newlineDAT, and 25% of RDF as basal dose; 25% of RDF each at 30, 60 and 90 DAT as sub plot newlinetreatments revealed that application of 150 % RDF along with 25% of RDF as basal dose; newline25% of RDF each at 30, 60 and 90 DAT recorded significantly higher seed yield (3038 kg ha- newline1), Gross and net returns and benefit:cost followed similar trend.
