INFLUENCE OF MULCH AND MANURE ON THE GROWTH AND YIELD OF FRENCH BEAN (Phaseolus vulgaris L.)

Abstract

An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during November 2020 to March 2021 to study the influence of mulch and manure on the growth and yield of french bean. French bean variety BARI Jharsheem 2 was used as planting material in this study. The experiment consisted of two factors: Factor-A: mulch materials (4 types): M 0 = No mulches, M 1 = Black polythene, M 2 = Rice straw and M 3 = Water hyacinth; Factor-B: T 0 = No manure, T 1 = Kitchen compost (5 t ha -1 ), T 2 = Vermicompost (7 t ha -1 ) and T 3 = Kitchen compost + Vermicompost (2.5 t ha -1 +3.5 t ha ). The experiment was laid out in a randomized complete block design (factorial) with three (3) replications. Data on different growth, yield contributing and yield parameter of French bean were recorded and significant variation was observed from different treatments. In case of mulch materials the tallest plant (56.04 cm), maximum number leaves plant -1 (18.54), leaf length (10.90 cm), leaf breadth (8.76), number of branch plant -1 (14.80), flower plant -1 (25.12), pod plant (20.74), seeds pod -1 (7.89), yield plot -1 (4.41 kg) and yield ha -1 (14.70 t) was observed from M 1 treatment. In case of manure the tallest plant (57.17 cm), maximum number leaves plant -1 (19.98), leaf length (10.98 cm), leaf breadth (9.42), number of branch plant -1 (8.94), yield plot (15.81), flower plant -1 -1 (26.82), pod plant (4.73 kg) and yield ha -1 -1 -1 -1 (21.72), seeds pod (15.77 t) was observed from T 3

treatment. The highest BCR (2.13) was obtained from the M 1 treatment combination where as the lowest BCR (1.17) was from M 0 treatment combination. It may be concluded that, sowing of French bean providing black polythene with 2.5 t ha -1 Kitchen compost +3.5 t ha -1 Vermicompost was recorded to be more suitable practice for getting higher yield of French bean.
