Abstract:
The studies were conducted in Department of Agrometeorology on MTU-1010, Rajeshwari and CG Sugandhit Bhog varieties of rice with 3 dates of sowing (1st June, 15th June and 30th June). For these studies, used long term (1989-2019) daily weather data for 3 districts (Raipur, Ambikapur and Jagdalpur). The result revealed that the duration from anthesis and maturity periods varied considerably in all the varieties under different sowing dates. Duration from sowing to maturity was more in 1^st date of sowing as compared to delayed sowing. Highest yield 4877 kg /ha was recorded in Rajeswari at Ambikapur district under D2 (15^th June) and lowest 2409 kg/ha was observed in CG Sugandhit Bhog under third date of sowing in Jagdalpur district. This shorting of duration was due to thermal stress at later sowing dates.
