The article presents the results of research to assess the impact of technological methods on the productivity of single and compatible crops of sugar sorghum with soybeans, and in particular the methods of sowing and fertilizing. The main organ of the plant that absorbs the most solar energy and has the highest intensity of photosynthesis is the leaf. The use of mineral fertilizers had a positive effect on the total leaf surface. During  years  of  the  research  with  the study methods of sowing and the timing for determination of total leaf surface in areas under mineral fertilizers were applied, it was greater than in areas without fertilizers. Thus, on average for 2018-2019 in the phase of ejection of panicles in areas where sugar sorghum was sown together with soybeans according to the scheme one row of sorghum + one row of soybeans under applying N120P90K120 leaf surface was 30.1 thousand m2/ha, and in areas without fertilizers - 21.0 thousand m2/ha. It was found that the largest area of assimilation surface of leaves on average for two years (41.3 thousand m2 / ha) was in the phase of milk ripeness of grain under sowing two rows of sorghum + one row of soybeans and N120P90K120  consumption. For the efficient use of solar energy is important not only the size of the leaf surface area but also the duration of its active work. Photosynthetic potential is used as an indicator for characterizing of the photosynthetic work of crops during the growing season.  The maximum value of the photosynthetic potential of sorghum plants on average for two years of research (2018-2019) was obtained at the end of the growing season (2.81 million m2 days/ha) in areas where it was sown together with soybeans in the method of sowing two rows of sorghum + one-row soybeans and under application of N120P90K120 doses.

 

Keywords: Leaf surface area, photosynthetic potential, sugar sorghum, method of sowing, fertilizer.
