CROP CAPACITY OF WINTER WHEAT DEPENDING ON THE SYSTEM OF SOILCULTIVATION AND FERTILIZATION
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 4, Issue 4
Abstract
The results of the three-year research aimed at studying the effect of the system of soil cultivation and fertilization levels on winter wheat crop capacity in the zone of the Right-bank Forest steppe of Ukraine were covered. It has been found out that different systems of the soil cultivation produce a certain effect on crop capacity of winter wheat. A considerable decrease of crop capacity of winter wheat grain is observed under regular mould boardless cultivation. On the average, in the years of this research this indicator was: under continuous mould board cultivation – 3.40 t/ha, under regular subsurface cultivation – 2.99, under differentiated cultivation – 3.49 and under continued shallow cultivation – 3.43 t/ha. It has been established that when mineral fertilizer dose is increased, their agro-technical efficiency decreases under subsurface cultivation, and it increases when share scuffler is used. The highest correlation between a marketable part of the yield and a non-marketable one was recorded when soil cultivation under winter wheat was done with help of a subsurface tiller, the lowest correlation was recorded when a plow was used. The substitution of plowing for the cultivation with a subsurface tiller decreased the output of low-valuable part of the yield. The results of the made analysis show that a fertilization system makes the major contribution to the productivity formation of the studied crops (68 %), and variants of the soil cultivation have a smaller effect on this indicator – only 17 %, whereas year conditions define a productivity level by 7 %.
