Yield capacity of mixes of oats with cabbage culture depending on fertilization in the conditions of the Polissya
Journal Title: Наукові горизонти. Scientific Horizons - Year 2018, Vol 64, Issue 1
Abstract
The article presents the results of research on the influence of mineral fertilizers, species composition of cabbage crops, and the terms of harvesting on the yield of green mass and grain of annual crops of oats with cruciferous crops in the conditions of Zhytomyr Polissya. During the years of research (2011–2013) it was found that when making mineral fertilizers in the norm, N60P60K60 + LCF (Rost-concentrate), mixtures of oat variety of Zhitomirsky with spring rape variety of Oksamyt and white mustard of Oslava provide during the flowering period of 30,3–39,2 t/ha of green mass, which is 16,7–26,7 t/ha more in comparison with the control. The growth of the green mass of mixtures was noted until the phase of grainy gravity. The height of the grass during the budding period irrespective of the type of cabbage crops was in the range from 29,5 to 80,3 cm; in the flowering phase – from 48,5 to 96,4 cm; in the period of fruit production – from 53,4 to 101,1 cm. The highest index of photosynthetic potential was observed for the introduction of mineral fertilizers along with non-root nutrition of plants. Compared to the non- fertilized version, the indicators were higher by 6,3– 9,5%, respectively. The yield of grain mixtures fluctuated within the range of 3,7–4,4 t / ha. A mixture of oats with rape crops on fertilized variants using nitrogen fertilizers provided the best crop of grain compared to a mixture of oats and mustard white. The efficiency of introducing phosphorus-potash fertilizers on grain yield was also found, which increased by an average of 14,6%. The introduction of nitrogen fertilizers in the normal range of 30 and 60 kg/ha in the background of P60K60 increased grain yield by 100,0 and 110,0% for rape, respectively, and 54,0 and 63,0% for white mustard compared to the variant without fertilizer. Additional addition of LCF to mineral nutrition increased the yield of grain in blends by 2,7-10,0% compared with the fertilizer variant N60P60K60.
