Abstract

A Field experiment was carried out during rabi 2018-2020 at RRTTSS, Kirei, Sundargarh district of Odisha to assess “Impact of different sowing dates and cultivars on Yield and Economics of blackgram during rabi in North Western Plateau zone of Odisha”. Three varieties (PU 31, IPU 0243 and OBG 41) were sown at spacing of 30 × 10 cm2 under five sowing dates viz., 8th November’19, 23rd November’19, 8th December’19, 23rd December’19 and 7th January’20. The experiment was laid out in FRBD with fifteen treatments and three replications. The treatment D1 V1 (8th November and variety PU-31) was found significantly superior with respect to yield over all other treatments. Among all varieties, PU-31 and among the sowing dates, 8th November’19 performed better followed by sowing date D2 (23rd November) and variety V3 (OBG-41). The variety IPU-0243 and sowing date D4 (23rd December) recorded with least yield and yield attributes. It was observed that when all the 3 varieties were sown on first date (8th November), highest yield (677 kg/hectare) was obtained whereas when all varieties were sown on fourth date (23rd December), the least yield (487 kg/hectare) was attained by the crop. The maximum gross returns (Rs. 34426.33/ha), net returns (Rs. 19408.56/ha), Return per Rupee invested (2.28) was recorded in sowing date D1 (8th November) and among all varieties, highest gross returns (Rs. 30612.84/ha), net returns (Rs. 15595.07/ha), Return per Rupee invested (2.03) was recorded in V1(PU 31). The fundamental hypothesis underpinning this experiment aimed to ascertain the optimal sowing date and the optimal choice of varieties for cultivation in the specified area. The proposed hypothesis holds the potential to offer valuable insights to farmers within the Sundargarh district, fostering enhanced crop productivity and facilitating high revenue generation.

Conclusion

On the basis of the field experimentation on Weather effects on yield of blackgram cultivars under different growing environment during rabi in North Western Plateau zone of Odisha, it could be concluded that the black gram variety PU 31 recorded with the highest yield over other two varieties, i.e., OBG 41 and IPU 0243 during the investigation under Treatment D1 8th November.
