ABSTRACT
A field investigation entitled "Response of pigeonpea to different drip fertigation levels” was carried out at Department of Agronomy Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the kharif season of 2016-17. The experiment was laid out in Randomised Block Design with four replications and eight different irrigation and fertigation treatments imposed for pigeonpea crop with an objective to study the efficacy of split application of N,P and K on growth, yield and economics of Pigeonpea. The experimental site was established with inline drip irrigation system (16 mm) lateral laid out at 90 cm with 30 cm dripper spacing. Irrigation water was applied through drip irrigation system on every alternate day at the rate of 100 per cent crop evapotranspiration level. Experiment results revealed that, in pigeonpea all the growth parameters viz. plant height, number of branches plant-1, root nodules plant-1, dry matter accumulation plant-1, yield attributes viz. Pod plant-1 and seed yield were substantially enhanced by drip fertigation levels at 125:100:100 per cent recommended NPK than lower fertigation levels (75 and 100 %), drip irrigation with 100 per cent recommended NPK and over conventional soil application in furrow with 100 per cent RDNPK kg ha-1. As a consequence of better growth and yield attributes, drip fertigation at 125:100:100 per cent recommended dose of NPK ha-1 had recorded higher pigeon-pea seed yield of 3866 kg ha-1.The GMR, NMR and B:C ratio was found maximum with 125:100:100 per cent RDNPK treatment. Drip fertigation as well as soil application of fertilizer had no significant impact on seed index, protein content and all the quality parameters of pigeonpea. It could be concluded that application of 125:100:100 per cent recommended dose of N,P and K in five splits found to be best for maximizing the yield and beneficial in increasing the productivity and economic returns of pigeonpea.
