EFFECT OF ROW ARRANGEMENT AND NITROGEN ON THE YIELD OF MAIZE INTERCROPPED WITU MUNGBEAN

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.
