ASSESSMENT OF THE NEW SOURSE MATERIAL FOR BREEDING EARLY AND AVERAGE MAIZE HIBRIDS
06.00.00 Agricultural sciences
Description
The article presents the result of correlation analysis of harvest structural elements. They have been analyzed for their effect on the biological yield inbred lines. The distribution of inbred lines in terms of manifestation of each trait separately was made. The final step was the evaluation of hybrids and calculation of economic efficiency of their implementation. As a result of the work, three hybrid combinations of corn were selected, and studying in further strain testing was suggested

PLANT RESIDUES AND SOIL FERTILITY
06.00.00 Agricultural sciences
Description
In the article, the review of results of studying of an annual cycle of decomposition of the vegetative remains of crops, which decompose under favorable conditions of moistening and temperatures during an annual cycle decays, on 80 to 100 % is given, and their complete decomposition is observed in 2 years. Their positive impact on soil fertility – increase in fermentation activity, humification increase, lack of toxicity is thus noted
