The Effect of Nitrogen and Sulphur Application on Soybean Productivity Traits in Temperate Climates Conditions

Both nitrogen and sulphur are important macronutrients necessary for the proper development yield of soybean. Moreover, plays a special role in metabolism plant, deficiency leads to reduction utilization from fertilizer. The objective this study was assess effect application on quality traits soybean seeds. following factors were analyzed experiment: I. Nitrogen rate: 0, 30 60 kg ha?1 applied at different times (before sowing and/or start seed filling stage); II. Sulphur 0 40 two portions: half during lateral shoots flowering. Thus 14 fertilizer combinations obtained. Result show that highest seeds obtained with N ½ before + after emergence (BBCH 73-75) ¾ +¼ emergence. In these combinations, did not significantly affect yield. remaining application, increased Taking into account chemical composition seeds, fertilization portions can be recommended—½ or remainder pods seeds—in combination application.
