Abstract:
A field experiment was carried out to study effect of nitrogen fertilizer on
morphology, growth and yield of tomato at the farm of Sher-e-Bangla Agricultural
University , Dhaka during October 2008 to March 2009 with four varieties, viz.,
BARI Tomato4, BARI Tomato-5. BARI Tomato-7, BARI Tomato-9 of tomato
and four levels of nitrogen viz., 0. 100, 150 and 200 kg N/ha using Randomized
Complete Block Design (RCBD) with three replications. The total yield of tomato
diflëred significantly due to the different varieties imposing different doses of
nitrogen. The maximum yield of fruits per hectare (95.75 t/ha) was obtained from
BARI Tomato-7 but the minimum yield of fruits per hectare (19.58 t/ha) was
obtained from BARI Tomato-5. Different nitrogen had also significant influence on
yield of tomato imposing 150 kg N/ha (N2) resulted in the highest yield (61 .421./ha)
over control (41.00 t/ha). In respect of combined effect. BARI Tomato-7 with 150
kg N/ha produced the highest yield per hectare (106.3 t/ha). On the other hand the
lowest yield (14.33 t/ha) obtained from the BARI Tomato-5 without nitrogen
application. Considering the above findings, BARI Tomato-7 with 150 kg N/ha
seems to be recommendable for tomato production.
