By following characteristics of soybeans and advantages of stubble sowing, as well as characteristics of the sowing machine Väderstad Rapid and its contribution to double cropping, a survey that includes differences resulting from the sowing Vaderstad Rapid direct or disc system in double cropping soybeans was conducted. The study was performed on the field Dragalić T4 in Okucani, after the harvest of barley. The study observed the soybean population and was recorded on three occasions. During the first measurement, it was noted that the Rapid disc system recorded better results because the soybean population was bigger, but the regrowing barley population was also bigger. By the second measurement is recorded that Rapid direct gave better results because the soybean population was bigger, and there was even four times less barley per square meter. By the last measurement Rapid disc system recorded better results again because soybean population was overall bigger and regrowing barley population was smaller. Based on the results under certain circumstances Väderstad Rapid disc system has yielded better results in the observed survey.
