A field experiment was carried out at Sher-e-Bangla Agricultural University Farm during the Rabi season of November 2008 to March 2009 to investigate effect of different levels of potassium fertilizer on the yield components of BARI Bush Bean-2. The red brown terrace soil of Tejgaon was silty clay loam having pH 5.6. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment comprises 4 levels of potassium in the form of MoP (0, 20, 40 and 60 kg potassium/ha). The results revealed that different levels of potassium showed significant variations on the yield and yield components of BARI Bush Bean-2. The treatment K40 (40 kg potassium) gave the maximum pod length (10.90 cm), pod diameter (2.95 cm), average single pod weight (5.49 g), total pod weight per plant (25.37 g), pod yield per plot (1795.83 g) and pod yield per hectare (4.38 ton). Thus the results of the experiment suggested that the use of 40 kg potassium produced highest yield of BARI Bush Bean-2 in red brown terrace soil of the Tejgaon series.
