Abstract
Two field experiments were carried out at a private field in ElMehala ElKobra Center, Gharbia Governorate, Egypt during the two summer seasons of 2000 and 2001. This investigation was aimed to study the effect of different plant distributions and microelements foliar application treatments on growth, yield, yield component and seed oil content of soybean (Glycine max, L. Merrill) cv. Giza 35. The experiments were included six plant distributions and seven treatments of microelements foliar application. A strip plot design with four replicates was used. The horizontal plots allocated with the following six treatments of plant distributions: 1.?Planting on one side of the ridge, 5 cm between hills, one plant per hill (D1). 2.?Planting on one side of the ridge, 10 cm between hills, two plants per hill (D2). 3.?Planting on one side of the ridge, 15 cm between hills, three plants per hill (D3). 4.?Planting on the two sides of the ridge, 10 cm between hills, one plant per hill (D4). 5.?Planting on the two sides of the ridge, 20 cm between hills, two plants per hill (D5). 6.?Planting on the two sides of the ridge, 30 cm between hills, three plants per hill (D6). On the other hand, the seven treatments of microelements foliar application and their concentration were devoted to the vertical plots as follows: 1.?Foliar spraying of Mn at concentration of 100 ppm (F1). 2.?Foliar spraying of Zn at concentration of 100 ppm (F2). 3.?Foliar spraying of Mo at concentration of 50 ppm (F3). 4.?Foliar spraying of Mn + Zn at concentrations of 100 ppm for each one (F4). 5.?Foliar spraying of Mn + Mo at concentrations of 100 and 50 ppm, respectively (F5). 6.?Foliar spraying of Zn + Mo at concentrations of 100 and 50 ppm, respectively (F6). 7.?Foliar spraying of Mn + Zn + Mo at concentrations of 100, 100 and 50 ppm, respectively (F7). It can be concluded that for maximizing seed and oil yields of soybean per unit area could be achieved by distribution soybean plants in arrangements that approach uniformity by planting on the two sides of the ridge, 10 cm between hills and leaving one plant per hill and/or planting on the two sides of the ridge, 20 cm between hills and leaving two plants per hill with foliar application the combination of Mn + Mo and/or the combination of Zn + Mo at concentrations of 100 and 50 ppm, respectively.
