Abstract
The aim of the research was to study technological methods that determine symbiotic and photosynthetic activity of soybean plants, peculiarities of symbiotic apparatus and leaf surface area formation, accumulation of organic matter during the growing period and its distribution in the organs of plants. In the article there are results of researches on studying of influence of different variants of primary tillage and herbicides in soybean cultivation technology on the performance of symbiotic and photosynthetic activity and seed yield. It is established that early moldboard plowing is the most preferred for the cultivation of soybeans in the conditions of Ulyanovsk region, especially with lack of moisture. The application of herbicides improves symbiosis and photosynthesis parametres, especially in the variant with zero tillage.
