Influence of Mulching and Organic Manure on the Growth and Pod Yield of French Bean (Phaseolus vulgaris L.)

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 mulching and organic manure on the growth and pod yield of French bean (Phaseolus vulgaris L.). 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 levels): M0 = No mulches, M1 = Black polythene, M2 = Rice straw and M3 = Water hyacinth; Factor-B: T0 = No organic manure, T1 = Kitchen compost (5 t ha-1), T2 = Vermicompost (7 t ha-1) and T3 = Kitchen compost + Vermicompost (2.5 t ha-1 +3.5 t ha-1). In the trial, the M1 (Black Polythene Mulch) treatment outperformed the M0 (No Mulch) treatment in terms of plant morphology and yield and yield attributes. Higher pod yields per hectare were produced by the organic manure T3 (Kitchen compost + Vermicompost) than by the control T0 (no organic manure). The investigation's top treatment combination was identified as M1T3 (black polythene mulch and kitchen compost + vermicompost), which had a 17.55 tha-1 yield potential. At the interaction level between mulching and organic manure, a significant correlation between the yield and yield components was found.
