Abstract:
The production potential of black gram under irrigated dryland conditions can significantly be improved by selecting suitable variety and matching the crop water requirement at suitable intervals. Therefore, a field trial was conducted during summer season of 2021 at Department of Agronomy, Agricultural College and Research Institute, Madurai, Tamil Nadu to examine the potential yield of blackgram varieties influenced by various irrigation regimes. The experiment was carried out in strip plot design with three irrigation regimes 100% ETc, 75% ETc, 50% ETc and five black gram varieties ADT 3, ADT 6, VBN 8, VBN 11, TBG 104 and each treatment was replicated thrice. Blackgram variety VBN 11 irrigated under 75% ETc resulted higher in plant height (40.45cm), number of branches/plant (19.68), haulm yield (1786 kg/ha). Irrigation scheduling under 75% Etc for blackgram var. ADT 3 recorded lower yield gap of 35.03%. From the study, it could be concluded that, application of irrigation based on the ETc requirement (75%) can significantly increase the yield and performance of black gram var. VBN 11.
