INFLUENCE OF MOISTENING CONDITIONS AND METHODS OF BASIC TILLAGE ON MAIZE PRODUCTIVITY IN THE SOUTHERN STEPPE OF UKRAINE
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 3, Issue 3
Abstract
The article presents the results of research on the study of the productivity of corn, depending on the impact of irrigation regimes and different methods of basic tillage. Corn on irrigated lands combined with the influence of sufficient amount of heat energy resources has the highest grain yield compared to all other crops, but it is necessary to improve agrotechnics of its cultivation in the south of Ukraine, in particular to optimize the irrigation regime and basic tillage. The purpose of the research was to determine the effect of moisture conditions and methods of basic soil cultivation on the formation of corn yields grown in southern Ukraine. The objective of the study was to determine the influence of the investigated factors on grain yield, the proportion of the influence of factors on plant productivity, the establishment of the specific gravity of the effects of moisture and basic tillage on the formation of yields, as well as the detection of the tightness of correlation-regression relations. It has been established that plowing at a depth of 28-30 cm in conjunction with the generally accepted irrigation regime with maintaining the moisture content of the calculated soil layer of not less than 70% of LMC (the lowest moisture content) has a positive effect on the yield of corn and contributes, on average over the years of research, to obtaining the highest grain yield in the experiment at 13.79 t/ha. The variance analysis showed that the maximum effect on yield is made by factor B (soil cultivation), whose fraction of influence is equal to 45%. Correlation-regression analysis has proved that the coefficient of determination of the relationship of yield is high at R² = 0.775, that is, the effect of irrigation and soil cultivation has a significant effect on plant productivity.
