The use of herbicides in the cultivation of corn

Abstract

Abstract The article discusses the results of studying the effectiveness of the use of new generation herbicides, both soil, applied before the emergence of maize seedlings – Merlin (150 g/ha); Cassius (50 g/ha), and for seedlings – Elumis (1.0-2.0 l/ha), on crops of three maize hybrids. The studies were carried out in the conditions of the foothill zone of the Republic of North Ossetia-Alania, on leached chernozems. The objects of research were different corn hybrids in terms of precocity (the originator of the KBNIISKH).) – Kabardinskaya 3812 (late-repining), Camilla SV (mid-late), a variety of white-grain food corn Bella 451, which is cultivated not only to obtain varietal seeds, forage, but also to meet the food needs of the indigenous population. The national cuisines of most of the peoples of the North Caucasus use flour and cereals made from white-grain corn. In this regard, it is very important to introduce into production, along with yellow-grain forms used for fodder, highly productive varieties and hybrids of white-grain corn for food purposes. Middle-late variety, food grade. As a result of the conducted studies, it was found that the treatment of the soil with the herbicide Elumis was more effective than the check. We had the following grain yield: Kabardinskaya 3812 hybrid – 8.7 t/ha, on the nonfertilized ground, 12 t/ha – on the fertilized ground, Camilla SV hybrid – 8.5 t/ha – on the nonfertilized ground, 11.7 t/ha – on the fertilized ground, and Bell 451 hybrid – the yield on the nonfertilized was 7.0 t/ha, on the fertilized ground – 9.9 t/ha. The response in yield of Kabardinskaya 3812 hybrid to the application of herbicides was more effective than other hybrids studied.
