GROWTH AND YIELD OF FRENCH BEAN AS INFLUENCED BY NITROGEN AND POTASSIUM

Abstract

This field experiment was conducted at the Horticulture farm of Sher-e- Bangla Agricultural University, Dhaka during the period of november 2015 to February 2016 to investigate the effect of different levels of nitrogen and potassium on the growth and yield of French bean. The experiment consisted of four levels of nitrogen viz.N 0 : control N 1 : 50 kg/ha, N : 90 kg/ha, N 3 :130 Kg/ha and three levels of potassium, viz. K 0 : Control; K : 90Kg/ha and BARIZhar sheem-1 was used as french bean variety. The experiment was laid out in Randomized Complete Block Design with three replications. Nitrogen had significant effect on the plant height, number of branch, leaf size, number of flower, number of pod per plant and pod yield per hectare. However, incase of nitrogen the highest yield(13.28 t/ha) was obtained from N 2 and lowest yield (10.41t/ha) was obtained from N .For potassium the highest yield (14.91 t/ha) was obtained from K 2 0 and lowest yield (10.78 t/ha) from K .Among all treatment combinations highest yield (18.04 t/ha) was obtained from N and lowest yield (9.61 t/ha) was obtained from N 0 K . So, 90kg N/ha and 90 kg K/ha may be used for french bean cultivation.
