Plant and Soil Science

Soybean yields can vary depending on the sowing density, geometric placement of plants, and environmental factors. The purpose of our research is to determine the effect of row spacing and plant density on the yield of different soybean varieties. The experiment was conducted during 2016-2017 in the Uman region of Cherkasy region, on the demonstration field of Sedna-Agro Ltd. The objects of the experiment were the soybean varieties of the company Euralis, namely Alligator, Senator and Mentor. Output data was analyzed using statistical analysis. The results of the study showed that there is a positive correlation coefficient between crop yield and density, and a negative correlation coefficient is established between the width of row spacing and the yield. This means that when increasing the density, as well as decreasing the row spacing, we observe an increase in productivity. Experiments involving factors such as sowing density and row spacing were carried out in the past in the world, and are being carried out to date. Many scientists in the world agree that with increasing seed rates, the yield of soybeans increases, but the question of optimal intermediate rows, and the individual reaction of the variety to change the row spacing and seeding density, remains open today. The generally accepted view is individual for each of the largest soybean countries, as well as scientists' conclusions, on the question of the influence of row spacing on yield, in many cases, are controversial and remain open to discussion.
