Abstract:
A field experiment was carried out to study the effect of mulching and nitrogenous
fertilizer on the growth and yield of tomato at the Horticulture Farm. Sher-c-langla
Agricultural University. Dhaka during October 2007 to March 2008. The
experiment consisted of three different types of mulches (Mo=No mulch.
M1
Blaek polythene and M
2
=White polythene) and four levels of nitrogen (viz.
No=0, N=230. N
2=240 and N
3
=250 kg N/ha) with their combinations were used as
treatments in the study. The experiment was conducted in a Randomized Complete
Block Design (RCBD) with three replications. In ease of nitrogen, N
2
resulted the
highest yield per hectare (59.73 tlha) and control produced the lowest (28.13 tlha).
Different mulching had also significant influence on yield of tomato. The yield per
hectare was the highest (59.83 t/ha) against black polythene mulch (M
i
) while the
control (no mulching) produced the lowest yield (35.75 1./ha). In respect of
combined elThet. application
of N2M1
produced the highest yield per hectare (82.25
kg/ha) and the lowest yield (24.10 1/ha) was obtained from the control treatment.
Considering the above findings, application of 240 kg N/ha with black polythene
mulch seems to be recommendable for tomato cultivation.
