SUMMARY

A field experiment was planned to evaluate the performance of cowpea [Vigna unguiculata L.Walp] released cultivars under different dates of sowing during 2020-23 at the Research Farm of Vegetable Science, CCS HAU, Hisar. In the present study, three verities viz., V1-P-263, V2-Kashi Kanchan and V3-Pusa Sukomal were sown at five different dates at 15 days interval i.e. D1-15 June, D2-1 July, D3- 15 July, D4-1 August and D5-14 August in Factorial RBD with three replications having plot size of 2.7 m x 2.0 m with spacing 45 cm x 20 cm. During 2020-21, the treatment combination D3V2 performed the maximum the production i.e. 99.30 q/ha followed by D3V1 (94.60 q/ha), D3V3 (93.80 q/ha), and D2V2 (93.80 q/ha). Likewise, during 2021-22, the treatment combination D3V2 performed the maximum the production i.e. 95.60 q/ha followed by D2V2 (93.10), D3V1 (91.70), and D3V1 (90.40). Opposite to earlier years results, during 2022-23, the treatment combination D2V2 performed the maximum the production i.e. 99.20 q/ha followed by D2V1 (95.30), D3V2 (94.50) and D2V2 (93.80). Therefore, sowing of cowpea variety, Kashi Kanchan may be recommended from 30th June to 15th July for commercial cultivation under Haryana conditions.
