Effect of fertilizer on wintering of winter rape

Abstract

The results of studies aimed at studying the effect of the use of fertilizing rapeseed sown winter crops with the complexes of microfertilizers Reak Chelat Bora and Quantum in the phase of four or six real leaves against the background of the main fertilizer on the growth and development of plants, their wintering. Studies were conducted during 2015-2017 in the Forest-Steppe of Ukraine on chernozem typical low-humus. As a result of the conducted studies it was found that the application of foliar fertilizing on the background of the main fertilizer ensures satisfactory growth and development of winter rapeseed plants during the autumn vegetation period and allows obtaining high plant safety parameters during the spring vegetation renewal period. High levels of preservation of plant cultures were obtained using variants using N₈₀P₆₀K₈₀ + Quantum in the phase of four to six true leaves.
