Abstract:
An experiment was organized at Oilseed Research Farm in C.S.A. University of agriculture and Technology, Kanpur (Uttar Pradesh) during karif season in 2017-18 to study the Effect of nutrient and pest management practices on growth and yield attributes; and yield of long duration pigeonpea (Cajanus cajan (L.) Mill Sp.). The experiment was laid out in Randomized Block Design in three replications. In the all treatments, recommended dose of fertilizer (N:P:K:S:Zn::20:50:20:20:20 kg ha^-1) was applied commonly. Experimental results were revealed that the application of T6 (RDF + 2% urea + 0.5% B + 0.5% Zn spray at 50% flowering) + Indoxacarb at flowering + one systemic insecticide 15 days after first spray was produced (2820 kg ha^-1) grain yield and Gross income (1,26,900 Rs.ha^-1); and B:C cost ratio (3.08), grain yield and B:C ratio was recorded 29.65% and 26.74% higher than the application of RDF. Therefore, on the basis of experimental data we may conclude that the application of RDF + 2% urea + 0.5% B + 0.5% Zn spray at 50% flowering + Indoxacarb 14.5% SC at flowering + one systemic insecticide 15 days after first spray was found appropriate to achieve the higher grain yield and economic return.
