EFFECT OF NITROGEN AND PHOSPHORUS APPLICATION ON THE GROWTH AND YIELD OF SARI BUSH BEAN-2

Abstract

A field experiment was carried out at the research field of Sher-e-Bangla Agricultural University. Dhaka ( Modhupur Frau, AEZ 28). during the rabi season from November 2007 to February 2008 to study the effect olnitrogen and phosphorus application on the growth and yield of bush bean (Phaseolus vz.ilgares L.) cv. I3ARI bush bean-Il. The treatments consisted of three levels of N i.e 0 kg ha1 (N0). 60 kg ha1(N i ). 120 kg ha1 (N2 ) and four levels of P i.e 0kg/ha (P t)) 30 kg ha'(Pi ) 60 kg hi' (P2) 90 kg hi' (P3) with 12 treatment combinations. Urea and iriple super phosphate (TSP) were used as the sources of nitrogen and phosphorus. respectively the maximum pod yield (16.63). seed yield (2.85) and stover yield (3.72 t ha") was obtained from the application of 120 kg N hi'. The results further demonstrated that parameters were significantly increased by different levels of phosphorus except plant height and plant population m 2 . The maximum pod yield (14.89), seed yield (2.79) and stover yield (3.92 t hi') were obtained from 60 kg P205 hi'. The combined effects of nitrogen and phosphorus was insignificantly influenced all the growth and yield contributing characteristic of bush bean except seed yield hi'. The highest pod yield (18.90), seed yield (3.09) and Stover yield (4.10 t ha1) were obtained form the treatment combination N2P2 (120 kg N with 60 kg P205 hi').
