Abstract
Background: Agronomic practices like supplemental irrigation, nipping, foliar nutrition of macro and micro nutrients and growth regulators are important for realizing the maximum yield potential in transplanted Pigeonpea. Hence the present study was carried out in combination with agronomic production management practices via supplemental irrigation, nipping, and foliar nutrition of macro and micronutrients, growth regulators on transplanted pigeonpea.
Methods: The experiment was carried out using a split plot design with sixteen treatment combinations with three replications during Kharif 2016-17 and 2017-18. The experiment included two degrees of irrigation as the primary factor, eight management techniques, fertilizer nipping and foliar spray, as well as a growth regulator as sub factor.
Results: The findings showed that among the different irrigation levels, irrigation each at pre-flowering and pod filling stage recorded significantly higher seed yield and yield parameter viz., number of pods and seed yield per plant at harvest. Among the management practices, nipping +1% pulse magic +1 % 19:19:19 NPK Spray at flowering and 15 days after first flowering recorded significantly higher yield and yield parameter and also higher returns.
