Soybean's importance comes first and foremost from the chemical composition of its grain, which is about 40% protein and around 20% oil.Because soybeans can be used whole or can be processed to obtain oil or protein, the plant is used widely and extensively not only in the food sector but in various other industries as well.According to many studies, the applied crop density is the prerequisite for expressing the maximum genetic potential for the yield of these varieties (Bullock et al., 1998; Bowers et al., 2000; Holshouser and Whittaker; 2002; Heatherly et al., 2002; Nenadić et al., 2003; Vignjevic, 2006; Popović, 2016a).[...]this parameter was called pure or Net Photosynthesis Productivity (Popović, 1976; Haloi and Balden, 1986; Kojić, 1987; Kastori, 1989).Bosa and Balkan, and at the fifth measurement, R4, at variety Dragana when the seed formation phase (R5) was established. * In the conditions of the arid and semi-arid climates, to whom northern parts of our country mostly belong, the advantage in the planting structure of the areas under the soybean should be given to medium-early varieties, with respect to the optimal sowing period (until April 10), and by this to try to avoid the adverse environmental conditions that were frequent in the summer months (June and July), especially in the last decade. * Significantly higher productivity of soybean photosynthesis can be achieved at smaller intervening distances (20 cm).
