Abstract:
A field experiment was conducted during kharif season of 2017-18 and 2018-19 at Agriculture farm of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.) to study the nutrient and pest management on growth and biomass productivity of pigeonpea. Growth parameters viz. plant height was recorded numerically higher under RDF + 1% Urea + 0.25% ZnSO4 + 0.25% Borax spray at 50% flowering while, trifoliate leaves per plant was noted markedly more under RDF + 0.5% Borax spray at 50% flowering. Biomass productivity in term of biological yield and stover yield was recorded significant superior and numerically higher primary and secondary branches per plant noted under RDF + 2% Urea spray at 50% flowering. Application of RDF + 2% Urea spray at 50% flowering gave 636 kg/ha (9.8%) more biological yield over control. Significantly maximum seed yield (1071.17 kg/ha) and conspicuous more plant dry weight was recorded under T8: RDF + Multimicronutrient spray @ 2 ml/lit at 50% flowering + Indoxacarb at flowering + one systemic insecticide 15 days after first spray.
