Influence of Mineral Fertilizers and Methods of Basic Tillage on the Yield and Oil Content of Sunflower

The purpose of the study was to evaluate influence mineral fertilizers and methods basic tillage on yield oil content sunflowers in north Kazakhstan. experiment conducted agricultural experimental Station Zarechnoye limited liability partnership with southern thin chernozem soils. Records observations growth development were carried out using modern methodological recommendations. used technique sunflower cultivation experiments one recommended for area. authors studied new hybrids different variants use tillage. paper concludes that it is important Sumatra, Suzuka Sumiko which achieve yields at level 1.34-1.46 c/ha an 48.52-48.88%, scientific novelty study. combined according scheme N40P40 autumn + N20P20 spring when sowing N10P10 fertilizing conditions zone increased harvest 1.34 0.65 t/ha. no-till improved biometric productive indicators. In this variant, a high obtained (1.31 t/ha) (48.49%) higher 0.63 t/ha provided. These improvements quality productivity as main oilseed crop are significant importance food security sustainable agriculture Northern
