INFLUENCE OF WINTER WHEAT PLANTS’ FOLIAR ERTILIZATION ON CROP’S YIELD AND QUALITY

Abstract

The article presents the results of experimental studies on the effect of foliar fertilization of winter wheat plants of sort Amandus with complex water-soluble fertilizers NAIS grain and Accelerator Micro on the background of N100Р58К100 on grain yield and quality. The research was conducted at Normagro LLC, Berdychiv district, Zhitomir region. The experiment included fertilizing winter wheat plants at the IV-V stages of crop organogenesis. The research was conducted on gray forest loamy soils. The use of these fertilizers proved to be quite effective. Compared with the background, the addition of conventional fertilizer with the studied fertilizers contributed to the increase in ear length and increase in the number of ears in the ear. The effect of using Акселератор Мікро was especially noticeable. The addition of background doses of fertilizers to the studied foliar fertilizers in our experiment affected the mass fraction of the crop, as evidenced by the data. At fertilizer N100P58K100 – received a crop – 6,08 t/ha, at N100P58K100 + «NAIS grain», 1,5 l/ha – productivity was 6,56 t/ha, at N100P58K100 + «Accelerator Micro» 1,5 kg/ha – 6,78 t/ha. In addition, the effect of combining the usual doses of fertilizers with foliar fertilization on the formation of the structure of the ear of wheat was studied. Among the studied parameters were the weight of one ear, the weight of 1000 grains, the nature of the grain. The weight of the ear with fertilizer N100R58K100 was –1,12 g, with N100R58K100 + «NAIS grain» (1,5 l/ha) – 1,17 g, and with N100P58K100 + «Accelerator Micro» (1,5 kg/ha) – 1,21 g, weight of 1000 grains – 42,3 g, 45,6 g, 48,9 g and nature of grain – 735 g/l, 745 g/l, 751 g/l respectively. The effect of the use of these fertilizers on the quality of the grain seed, in particular on the content of protein, gluten, ash and glassiness of the grain, was positive. A significant increase was obtained with the use of «Accelerator Micro», compared with «NAIS grain».
