Abstract:

A field experiments was conducted during Kharif season of 2015 at Chaudhary Charan Singh Haryana Agricultural University, Rice Research Station, Kaul, India to study the phenology, and various agrometeorological indices viz., accumulated growing degree days (GDD), helio thermal units (HTU), photo thermal units (PTU), radiation use efficiency (RUE) and heat use efficiency (HUE) of basmati rice cultivars grown under different dates of transplanting. The rice varieties CSR 30, HB 2, PB 1121 and PB 1509 were transplanted on three dates viz., 25th June, 10th July and 25th July. Heat units required to attain different phenological stages decreased in all the varieties with every delay in transplanting date. The crop transplanted on 25th June took maximum calendar days, growing degree days, helio thermal units and photo thermal units, to attain different phenological stages till physiological maturity which reduced significantly with subsequent delay in transplanting date. Also, Radiation and heat use efficiency was found to be highest in crop transplanted on 25th June followed by 10th July and 25th July. Among varieties, CSR 30 consumed highest GDD, HTU and PTU as compared to other varieties. The RUE and HUE for grain production was highest in HB 2 at the time of harvest.
