ABSTRACT
A field experiment on verification of yield targetting equations with and without organic matter for optimization of yield of pigeonpea was conducted during kharif at the Pulses Improvement Project, M.P.KV., Rahuri. The soil of the experimental site was low in available nitrogen (182 kg ha-1), available phosphorus (8.9 kg ha-1) and high in potassium (602 kg ha-1). The field experiment was laid out in Randomized Block Design with three replications, consisting of twelve treatments viz., control, recommended dose, as per soil test, 15,20 and 25 q ha-1 yield target STCR equation, FYM@ 5 t ha-1, recommended dose + FYM @ 5 t ha-1, as per soil test + FYM @ 5 t ha-1 15,20 and 25 q ha-1 yield target STCR equation + FYM @ 5 t ha-1 . Pigeonpea yield was increased by application of increasing levels of chemical fertilizers as per the targeted yield approach with FYM. The treatments of conjoint application of NPK fertilizers and FYM recorded higher yield over the treatments where, only NPK fertilizers were applied as per yield targeting equations. The conjoint use of chemical fertilizers along with organic manure was beneficial for higher economic yield of pigeonpea.
