Abstract:
The experiment was conducted at the Research Farm of Sher-e-l3angla
Agricultural University, Dhaka-1207. during November 2008 to March 2009 to
evaluate the effect of nitrogen (N) and phosphorous (P) on the growth and yield
component of BAR! tomato-2 (Ratan), is one of the high yielding varieties of
indeterminate type. The experiment was laid out in a Randomized Complete Block
Design (RCBD) with three replications of each fertilizers treatment combination.
The treatments used were: four levels of nitrogen as No: 0 kg N/ha, N
100: 100 kg
t
N/ha. N150
: 150 kg N/ha and N
200
: 200 kg N/ha and four levels of phosphorous as
P0: 0 kg P
205/ha, P50: 50 kg P
205Tha, P
100: lOU kg P
205!ha and p150: 150 kg P

/ha with 16 treatment combinations. Yield and yield contributing characters, N and
P concentration in plant and post harvest soil were recorded. Plant height at 60
days after transplanting, number of branches per plant, number of flowers per
plant, number of fruits of plant and fruit weight per plant increased significantly
with increasing N level up to 150 kg N/ha, whereas fruit yield increased
significantly up to 200 kg N/ha. All these parameters also increased significantly
with increasing the level of P up to 150 kg P/ha. However, the treatment
showed the maximum plant height at harvest (93.62 cm). On
the other hand, the treatment combination N20oPI00 produced the maximum
combination N
200?
ISO
number of flowers per plant (49.86), number of fruits per cluster (3.99), number of
fruits per plant (38.30) fruit weight (2.5
kg/plant) and fruit yield (89.93 tlha). N
and P concentrations in shoot and fruit were the highest in N
200P150 treatment. The
treatment had no significant effect on pH of post harvest soil. However increasing
the application of nitrogen increased soil total N and P content up to N
150
treatment. Application of P had not significant effect on total nitrogen but P
150
produced the highest P content in soil. N
200?150
combination had the highest N
(0.119%) and P (44.77 ppm) concentration in plant.
