Potential of corn hybrids of universal use

Abstract

This article presents the results of studies of corn hybrids of a universal direction. Their responsiveness to the application of mineral fertilizers, incrustation of seeds with biological preparations, and foliar fertilizing with zinc-containing preparations is shown. NK background at 60 t/ha + foliar application of Zn ensures maximum grain yield and better disclosure of the grain potential of hybrids of universal use (61.3 c/ha for the Nur hybrid, 67.41 c/ha for the Bilyar-160, 77, 39 c/ha for the Voronezhsky-279 hybrid). Early ripe hybrids in the conditions of the Fore- Kama region of the Republic of Tatarstan form stable grain yields due to lower pre-harvest moisture. Mid-early hybrids of universal use respond well to the application of mineral fertilizers and foliar feeding with zinc-containing preparations, providing high grain yields.
