Abstract
The inoculation of crops of bioenergetic crops even within one soil-climatic zone has its own specifics. These features are primarily related to the conditions prevailing in crops of different crops, the beginning and duration of their vegetation, specific allelopathic relationships, requirements for soil cultivation and peculiarities of care for plants. The purpose of research. Determine the photosynthetic potential of weeds in cereal grains according to its density. Research. Objectives: to establish the photosynthetic parameters of weeds in the crops of millet species, depending on its density. Research methods. Common and special methods are used: Field - study of conditions of cultivation and agro measures on productivity of millet; laboratory - definition of quantitative and qualitative characteristics; statistical - the establishment of mathematical models and statistical dependencies between the investigated factors and processes. Results. It was established that the photosynthetic potential of plants increased by -100 ppm for the densely-sliced crop of 100-ppm / m2, and the total photosynthetic potential of weeds at this density was 3.1 million m2 / g. Subsequently, for increasing the density of cultivated plants up to 150 pcs. / m2, their photosynthetic potential increased to 1.46 and in weeds it decreased to 2.5 million m2/ g. The maximum photosynthetic potential of the 200-ppm square-straw plants in the experiment was maximum in the experiment - 1.88, but the total photosynthetic potential of weeds at this density was 2.1 million m2 db / ha, to some extent responding parameters of cultivated plants. However, further growth of the density of crops of millet is not feasible due to the sharp sharpening of the competitive struggle between cultivated plants
