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.
