A Field experiment was carried out during rabi 2018-2020 at the Regional Research and Technology Transfer Station, Kirei, Sundargarh district of Odisha to assess “Effect of Agrometeorological Parameters at different Phenological Stages Of Blackgram(Vigna mungo)Under Different Sowing Dates during rabi in Sundargarh”.Three varieties(PU31, IPU 0243 and OBG41) were sown at spacing of 30 x 10 cm2under 5 sowing dates viz., 8th November’19, 23rd November’19, 8th December’19, 23rd December’19 and 7thJanuary’20. Among all the dates and varieties, the mean highest Growing Degree Days was accumulated on D1 (8th November) and by variety (IPU0243), whereas themean maximum Helio Thermal Units and Photo Thermal Units was attained by crop when sown onD5 (7th January) andby IPU 0243. In the case of weather parameters, temperature requirement and relative humiditywere highest when sown on 8th November by IPU 0243whereas the lowest temperature and relative humidity was recorded on 7th January. When the crop was sown on all five dates,the maximum temperature was received by variety IPU 0243)followed byOBG 41 which was par withPU 31.
