The experiment was conducted at Central Research Farm, Bangladesh Agricultural Research Institute, Joydebpur and Regional Agricultural Research Station, Jessore during the rabi season of 1997-98 and 1998-99 but at Regional Agricultural Research Station, Hathazari in 1998-99 in Bangladesh. Eight treatment combinations were evaluated such as:
T1 = Maize normal row + 2 rows soybean with 300-150- 150-60-6 of N-P2O5-K2O-S-Zn Kg ha-1
T2 = Maize normal row + 2 rows soybean with 260-120- 120-40-6 of N-P2O5-K2O-S-Zn Kg ha-1
T3 = Maize normal row + 2 rows soybean with 200-80- 80-20-6 of N7,P5-K2O-S-Zn Kg ha-1
T4 = Maize normal row + 2 rows soybean with 160-60- 60-10-6 of N-P2O5-K,O-S-Zn Kg ha-1
T5 = Maize paired row + 4 rows soybean with 300-160- 160-60-6 of N-P2O5-K,O-S-Zn Kg ha-1
T6 = Maize paired row + 4 rows soybean with 260-120- 120-40-6 of N-P2O5-K,O-S-Zn Kg ha-1
T7 = Maize paired row + 4 rows soybean with 200-80- 80-20-6 of N-P2O5-K,O-S-Zn Kg ha-1
T8 = Maize paired row + 4 rows soybean with 160-60- 60-10-6 of N-P2O5-K,O-S-Zn Kg ha-1
The hybrid maize (var. Pacific 11) and soybean (var. Sohag) were used in this experiment. The unit plot size was 4.6 x 6 m2. Seeds were sown on 9th December, 1997 and 9th December, 1998 at BARI, Joydebpur, 1st December, 1997 and 8th December, 1998 at RARS, Jessore and 20th December, 1998 at RARS, Hathazari. Maize in normal row was planted at 76 x 25 cm2 spacing and paired row system was 37.5/150/37.5 cm and soybean was planted 2 or 4 rows between maze rows at 30 cm row spacing. The whole amount of P2O5K2O, S, Zn and 1/3 N were applied as basal in the form of triple super phosphate, muriate of potash, gypsum, zinc sulphate and urea, respectively. The rest of N was top- dressed in two equal splits at 35 and 65 DAE (days after emergence) as side dressed to maize rows. The irrigations were applied at 30, 50 and 70 DAE. Soybean was sprayed four times with Dimecron 100 WSC to control leaf roller. Soybean was harvested at 100 DAE and maize was harvested at 140 DAE. Data on yield and yield components were recorded, The recorded data were analyzed statistically by Randomized Complet e Block Design (RCBD) and means were compared by Least Significant Difference . Total rainfall recorded during crop growing season were 126.4 mm in 1997-98 and 4.8 mm in 1998-99 at Joydebpur.
