Abstract:
The experiment was conducted at the research field of Sher-e-Bangla Agricultural
tiniversity, Dhaka during the period of December, 2007 to May, 2008 to study the
influence of sowing pattern and nitrogen levels on the productivity under maizechickpea
intercropping system in a Randomized Complete Block I)esign (RCBD) with
3
replications. The experiment comprised seven treatments viz, T
1
= Sole maize normal
row
(MNR) with 120 kg N ha". 12 = Sole maize
paired
row (MPR) with 120 kg N ha4,
13 = MNR + 2 chickpea rows with 120 kg N ha", T.1
= MNR + 2 chickpea rows with
90 kg N ha
',
15
= MPR
+ 5 chickpea rows with 120 kg N ha", T
6
= MPR
± 5 chickpea
rows
with 90 kg N ha" and T7
= Sole chickpea with 20 kg N ha". The results revealed
that
15
showed better performance than the other intercropped treatments and sole
crops
in respect of total grain yield and economic benefit. From the economic point of
view,
the sole crops showed the lowest performance. Maximum grain yield of maize
(4506
kg ha") and chickpea (1623 kg ha") were obtained in I and 1
7
.
respectively.
The
highest maize equivalent yield (7664 kg ha") was found in Ts and the lowest in
12
(4192 kg ha"). The highest LER (1.70) was observed in T
5, which also gave maximum
net return (91419 1k ha") with the maximum BCR (2.96) whereas; the lowest LER
(1.37) was recorded in 1
4 in intercropping situation.
