Abstract:
An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University. Dhaka during the period from October 2004 to February 2005 to study the
, .
effect of different levels of fertilizer and manure viz. control. organic manure (23.11-
t/ha), inorganic fertilizer (Urea 3~2 k&/lta, MP 180 kglba, TSP 158 kgIha) and mixture
of organic and inorganic fertilizer (Cowdung 11.5 tJha, Urea 177 kg/ha, TSP 62 kg/ha
and MP 63 kglha) and different mulching materials viz. no mulch ~), rice straw
(MI). water hyacinth (M2) and black polythene (M3) on the growth and yield of
lettuce. The experiment was conducted in the"'Rand()mizedComplete Block Design
~ ...
(RCBD) with three replications. "APpliCation of different levels 'of fertilizer and
manure significantly influence the growth and yield of lettuce. Organic plus
inorganic fertilizer treatment resulted in the highest gross (46.01 tJha) and marketable
yield (45.46 t/ha). The highest yield (45.7t1ha) was recorded from black polythene
mulch, while the lowest (38.71t/ha) was recorded from unmulch treatment. The
combined effect of various levels of fertilizer and manure as well as mulches were
..... also found significant incase of lettuce production. The use of organic plus inorganic
fertilizer with black polythene mulch produced the highest gross (50.27 t/ha) and
marketable yield (49.62 tlha). The lowest gross (35.44 tJha) and marketable yield
(34.9 t/ha ) were recorded from the control treatment where no manure and fertilizer
as well as no mulch were used. The benefit cost ratio (BCR) was the maximum (3.23)
in the treatment combination of cowdung with water hyacinth mulch whereas, the
minimum (2.09) was recorded from the water hyacinth with no fertilizer treatment
