Abstract:
An experiment was conducted at the Agronomy field at Sher-e-Ban€zla
Agricultural University. Dhaka during the period from March to June 2006 to
study the effect of row arrangement and nitrogen on the yield of maize
intereropped with mungbean. The experiment was conducted in a Randomized
Complete Block Design (RCBI)) with 3 replications. The treatments were T
1 =Solc
maize nonnal row (MNR) with 120 kg N.fha.T
2
Sole maize paired row
(MPR)
with 120 kg N/ha, T MNR + 2 mungbean rows with 120 kg N/ha. T
4 = MNR ±
2 mungbean rows with 60 kg N/ha, T
5
= MPR - 5 mungbean rows with 120 kg
N/ha. T
(, = MPR 1
5 mungbean rows with 60 kg N/ha, T
7 =
Sole inungbean with
30 kg N/ha. In all the treatments, the reeommcnded plant population of maize
(55,555
plants/ha) was maintained. Recommend plant population of mungbean
(3.33,333 plants/ha) in sole situation and (2,22.222 plants/ha) in intercropped
treatments were maintained. Maximum grain yield of maize (4283.00 kg/ha) and
mungbean (1.087.00 kg/ha) were obtained in T
1 and 17. respectively. 1-lighest
maize equivalent yield (6002.00 kg/ha) was found in T
5 and the lowest (3623.30
kg/ha) in 17
. Land equivalent ratio (LER) vaied from 22 to 53% in the different
treatments. Highest LER (1.53) was found in Ic which also gave maximum net
return (T139000.00/1ta)
with benefit cost ratio (BCR) (2.60). Lower LER (1.22)
was
recorded T.1.
