Abstract:
A field experiment was conducted at college farm, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad during 2016-17 and 2017-18 on applied as well as residual phosphorus and defoliant on pigeonpea under pigeonpea-maize cropping system. The results of the present investigation reflected that the pigeonpea plant exhibited maximum values of yield and uptakes of NPK by applying of T₂ (20: 50: 0 N: P₂O₅: K₂O kg ha^-1) during both years of study. During the both years of study highest seed yield (1567 kg ha^-1and 1605 kg ha^-1) respectively and grain, straw and total NPK uptakes (136.36, 14.78 and 46.27 kg ha^-1 during 2016) and (148.87, 16.19 and 50.86 kg ha^-1 during 2017) respectively was obtained by applying T₂ (20: 50: 0 N: P₂O₅: K₂O kg ha^-1) followed by T₄(20: 75: 0 N: P₂O₅: K₂O kg ha^-1) (129.86, 13.66 and 43.06 kg ha^-1 during 2016) and (143.46, 15.07 and 49.52 kg ha^-1) of pigeonpeacrop in pigeonpea-maize cropping system.
