Abstract:
A field experiment was conducted during kharif season 2020 and 2021 at research farm of Department of Agricultural Meteorology, Chaudhary Charan Singh Haryana Agricultural University, Hisar to evaluate the agromet indices on pigeonpea varieties under various crop geometry. The results revealed that highest GDD, HTU and PTU were recorded in 60 × 10 cm crop geometry and Pusa 992 from seedling emergence to physiological maturity in both the crop seasons. The GDD (2552.6 and 2611.1 °C day) was recorded highest in wider crop geometry (60 × 10 cm) followed by 40 × 10 cm and 30 × 10 cm at physiological maturity in both the crop seasons. The HTU (17628.3 and 15893.6 °C day hour) was recorded highest in wider crop geometry (60 × 10 cm) followed by 40 × 10 cm and 30 × 10 cm at physiological maturity in both the crop seasons. The PTU (31469.3 and 32155.8 °C day hour) was recorded highest in wider crop geometry (60 × 10 cm) followed by 40 × 10 cm and 30 × 10 cm at physiological maturity in both the crop seasons. Among the pigeonpea varieties Pusa 992 recorded highest GDD, HTU and PTU at physiological maturity followed by Manak, Paras and PAU 881 in both the crop seasons.
