Abstract:

A field experiment was conducted at the Agronomy Department farm, Dr. PDKV, Akola during summer season 2011 to study the phenology and heat unit requirement of summer green gram varieties grown under different sowing dates. As early sowing faces low temperature while late sowing faces high temperature during initial stage in Akola. The crop sown early (1st march) took 73 days from sowing to maturity. While late sown green gram (30th March) took 67 days for physiological maturity. Sowing on 30th March accumulated significantly higher GDD, HTU and PTU at harvest (1549.61 OC day, 12109.40 OC day hour and 20609.8 OC day hour, respectively) as compared to rest of sowing dates from anthesis to physiological maturity. In case of varieties, PKV-Green gold accumulated significantly higher GDD, HTU and PTU at harvest (1593.91OC day, 12457.62 OC day hour and 20960.9 OC day hour, respectively) followed by variety PKV-AKM-04, whereas Pusa Vaishakhi recorded lowest values at all growth stages of crop. Sowing on 20th March recorded significantly higher HUE and PUE for grain and biomass due to optimum temperature throughout the growth period. In respect of varieties HUE and PUE were higher in Pusa Vaishakhi viz; 0.738 kg ha-1 OC day-1 and 0.056 kg ha-1 OC day-1 for grain and 2.15 kg ha-1 OC day-1 and 0.164 kg ha-1 OC day-1 for biomass.
