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').
