EVALUATION OF THE EFFICIENCY OF CROPING HIGH-YIELD AND PERSPECTIVE CORN HYBRIDES IN ADYGEA

Abstract

The article presents the results of the research, according to a comparative assessment of the most promising maize hybrids of the Federal State Budget Scientific Institution «NGC named after P.P. Lukyanenko» breeding, proposed for cultivation in the foothill zone of the Republic of Adygea. When observing the vegetative period of corn plants, its length was noted to be about 116-124 days, depending on the hybrid. The Krasnodar 395СВ VL hybrid stood out for a longer vegetation period, and the Krasnodar 377AMV hybrid turned out to be the most precocious. According to the parameters of plant growth and the height of attachment of the cob to the stem, the Krasnodar 395СВ ВЛ (132 cm) hybrid stood out, the lowest indicators were noted for the Krasnodar 377AMV hybrid (118 cm).The formation of a high leafy mass along with a high yield of full-fledged corn grain is very important for livestock. In this case, an advantage in productivity indicators was noted for the Krasnodar 395СВ VL hybrids with a grain yield of 48,3 t/ha and Krasnodar 385MV – 45,3 t/ha. Higher grain yields were obtained from the Krasnodar 395СВ VL hybrid – 6,48 t/ha of grain, which exceeded other samples by an average of 0,20-0,44 t/ha of grain, and it turned out to be the most profitable among the studied hybrids (85,1 %).According to the results of the study, agricultural producers of the Republic of Adygea will benefit from the cultivation of domestic maize hybrids such as Krasnodar 395СВ ВЛ and Krasnodar 370МВ, which are able to ensure high profitability of manufactured products within 85,1 %, 80,9 %, respectively.
