The cold spring and low temperatures at the beginning of sowing had a negative impact on the development of soybeans in Ukraine. Due to the delayed emergence of shoots in some sowings, a low formation of lower pods may occur, leading to harvest losses during harvesting. This was reported by the agrotechnology development manager in the Central region of LNZ Group, Serhiy Ivanyuk, as written by SuperAgronom.com.

According to him, soybean sowing started in the second decade of April this year. Early sowings due to significant cooling only sprouted after 11-18 days, while for later sowings, they appeared after 9-12 days.

Ivanyuk mentioned that the cold ground and low air temperatures delayed the emergence of soybean shoots, negatively affecting the initial plant development. In particular, they formed a lower central stem, and in varieties with genetically determined branching, lateral shoots were more actively formed.

At the same time, in varieties without a tendency to branch, the low placement of the subfamily node can lead to the formation of lower pods too close to the ground, which will increase harvest losses during harvesting. According to the expert’s assessment, each pod left on the plant after the combine passes reduces the yield by approximately 1 ton/ha.

In traditional “soybean” regions, the situation remains uneven, Ivanyuk says. The best growth and development of plants are currently observed in the south of Cherkasy and Vinnytsia regions, as well as in the northern part of Kirovohrad region.
