The crop sown on 2nd fortnight of July accumulated maximum growing degree days, photo thermal units, heat use efficiency, helio thermal use efficiency and photo thermal use efficiency whereas the highest helio thermal units were recorded under 2nd fortnight of August sowing to attain different phenological stages till maturity. Among different spacings, 45 × 15 cm treatment accumulated highest growing degree days, helio thermal units and photo thermal units, heat use efficiency, helio thermal use efficiency and photo thermal use efficiency as compared to other. | Response of pearl millet to weather health indices under different spacings and sowing windows in coastal agro- ecosystem of Andhra Pradesh India
