Response of BARI Bush Bean-2 at Different Levels of Nitrogen Fertilization

A field experiment was carried out at Sher-e-Bangla Agricultural University Research Farm during the Rabi season of 2008 to investigate the response of BARI Bush Bean-2 at different levels of nitrogen fertilization in respect of various yield components. The soil of the experimental area belongs to the ModhupurTract (AEZ No. 28) which had shallow red brown terrace soil. The selected plot was medium highland and the soil series was Tejgaon. The experiment was laid out in a RCBD design with three replications. The experiment comprises 4 levels of nitrogen in the form urea (0, 40, 80 and 120 kg ha-1 N). The results obtained revealed that different levels of nitrogen showed significant variations on the different parameters studied. Among the different treatments of the study the treatment N80 (80 kg N) gave the highest pod length (11.15 cm), pod diameter (2.93 cm), average single pod weight (5.42 g), total pod weight plant-1 (25.63 g), pod yield plot-1 (1789.58 g) and pod yield hectare-1 (4.37 ton). Thus the findings of the experiment revealed that the use of 80 kg N maximally influence the yield and yield contributing characters of BARI Bush Bean-2 in the selected red brown terrace soil of the Tejgaon series.
