Abstract

The article presents results of the study of maize (Zea mays L.) varieties from collection of National Genbank at the Institute of Genetic Resources, in optimum conditions of cultivation (supply rainfed) of maize in Azerbaijan, Zakataly Regional Experimental Station of the Research Institute of Crop Husbandry, obtained on study of yield structural elements and productivity depending on the use of pre-sowing seed treatment with ozone-air mixture. In check variant, the seeds of the varieties were treated with Vitavax. It was found that in check variant, the studied varieties of maize are characterized by vegetation period on average 96-120 days, and in the experimental variant - 94-117 days. Results of the study indicate that, despite the short cob length in most varieties, the number of seeds in a row, the output of seeds from the cob, 1000 kernel weigh and, accordingly, productivity was higher in the experimental variant. According to the study it was found that in check variant at the studied varieties, the length of the cob is longer, but due to the incompleteness of top of the rachis, the number of seeds on the cob is not the maximum possible, which is due to the high temperature and lack of moisture accompanying the flowering and fertilization period. But in the experimental variant, a completely different view was observed, because under the same growing conditions the cob almost all of the studied varieties were nearly completely filled, which is explained by the increased adaptability of plants due to the stimulating effect of ozone on the development already from the early stages. Differences in the dynamics of ripening of maize varieties caused by pre-sowing seed treatment with ozone-air mixture affected productivity. As a result, the effectiveness of pre-sowing treatment of seeds of maize varieties with ozone-air mixture in a 5000 ppm x min regime was revealed.
