Abstract:

A field experiment was conducted to study the impact of sowing time and supplemental irrigation on growth and yield of rabi pigeonpea at Regional Agricultural Research Station, Lam, Guntur. The results revealed that the maximum grain yields were recorded when the crop sown from 1st September to 1st October. A significant reduction in yield was observed when the crop sown beyond 15th October. Response to three supplemental irrigation was more when compared to that of less number of irrigations (either two or one) given at critical growth stages of pigeonpea with respect to growth and grain yield. Application of three irrigations at 50 days after sowing, flowering initiation and pod development recorded significantly higher grain yields (1701 kg ha-1 and 1595 kg ha-1), net returns (Rs. 55,773/- and Rs. 61,023/-) and BCR (0.97 and 1.12), respectively, during both the years of study.
