Foliar nitrogen feeding and growth regulating fertilizers as factors of photosynthetic potential formation in winter rape

Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 101, Issue

Abstract

The article presents the results of five-year-long field research, conducted under the conditions of the Yelanets district of the Mykolaiv region on ordinary low-humus black soils. The research is directed towards the improvement of the mineral feeding system for winter rape. The studies have proved that the interaction of feeding with nitrogen fertilizers in combination with foliar treatments of vegetative plants with Helafit Combi® produces a synergetic effect, which results in an increase in the the leaf surface area by 18%, and an increase in the content of chlorophyll in leaves by 33–35%. The studies have demonstrated that the yield of winter rape reaches the maximum values after the early spring treatment with the nitrogen fertilizer (rate N90) in combination with two applications of foliar feeding with growth regulating fertilizer Helafit Combi®. Yield increase for the cultivar is 0.79 t/ha, and 1.11 t/ha for the hybrid.
