EFFECT OF NITROGEN AND POTASSIUM ON THE GROWTH AND YIELD OF BARI BUSH BEAN-2(Phaseolus vu/garth)

Abstract

A field experiment was earned out at Sher-e-I3angla Agricultural University Farm during the Rahi season ol' 2008 to investigate the efThet of nitrogen and potassium on the growth and yield of F3ARI [lush Bean-2. The red brown Larrece soil of lejgaon was silty clay loam in fCXtUrc having pH 5.6. The experiment was conducted in a RCBD with three replications. The experiment comprises 4 levels olnitrogen from urea (0 kg. 40 kg. 80 k g- and 120 kg nitrogen/ha) and 4 levels of potassium from MOP (0 kg. 20 kg. 40 kg and 60 kg potassium .ha). There was combination of' sixteen treatments including control (no fertilizer). The results obtained revealed that dilIercnt levels of nitrogen and potassium showed significant variations on the parameters studied. The treatment N QKjl (80 kg nitrogen 1 40 kg potassium) gave the highest pod length (11.67 cm), pod diameter (3.13 cm), average single pod weight (5.99 gm). tolal pod weight per plant (29.07 gm pod yield per plot (2033.33 gm) and pod yield per hectare (4.96 ton). The highest N. P. K and S content in harvested plant sample (2.92 %. 0.20 %. 2.85 % and 1.04 % respectively) were also obtained with treatment N 89 K. (80 kg ). nitrogen 1 40 kg potassium). Thus the findings of the experiment suggested that combined use of 80 kg nitrogen + 40 kg potassium produced maximum growth and yield of BARI Bush Bean-2 in red brown terrace soil of the lejgaon series.
