abstract
The present investigation entitled ‘Effect of humic acid and zinc sulphate on growth and yield of French bean’ was carried out at Horticulture Farm of Palli-Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan, West Bengal during Rabi season of 2021-22. The experiment was laid out in a factorial randomized block design consisting of nine treatments with three replications. Treatments comprised of soil application of humic acid (0, 10 and 15 kg per hectare) and foliar application of zinc sulphate (0, 0.75% and 1%). The characters studied in this experiment are plant height, number of branch per plant, number of days to first flowering, fifty percent flowering, 100% flowering, average pod yield per plant, pod yield per plot, pod yield per ha-1. The statistical analysis indicated that humic acid and zinc sulphate failed to show any remarkable influence on growth and yield of French bean. The growth and flowering parameters like plant height, number of branch per plant, number of days to first flowering, 50 percent flowering, and 100% flowering were not positively affected by combined application of humic acid and zinc sulphate. However, number of days to 50 % flowering significantly influenced with zinc sulphate. On the other hand, yield attributes like pod length, pod diameter, number of pod per plant, average pod weight, pod weight per plant, pod weight per plot, total pod yield per hectare showed non- significant effect towards application of humic acid and zinc sulphate, though, mere numerical variation was observed. However, pod weight per plant influenced significantly with various level of zinc sulphate.
