Productivity and economic efficiency of sunflower growing in different crop rotations depending on fertilization systems
Mashchenko Yu. V., Sokolovska I. M., Tkalich Yu. I.
The article presents the results of a study on the elements of sunflower cultivation technology as an important oilseed crop, proposing ways to optimize production in short-rotation crop rotations with varying sunflower saturation, balanced use of mineral fertilizers, organic residues, and biopreparation. The highest productivity and economic efficiency indicators for sunflower cultivation were obtained in a grain-fallow-row crop rotation (sunflower share 20 %) under an organo-mineral biologized fertilization system: seed yield – 3.42 t/ha, oil yield 67 t/ha, conditional net profit – 57,138 UAH/ha with a profitability level of 174.2%. The economic efficiency of sunflower cultivation primarily depended on the crop rotation factor – a decrease in sunflower concentration contributed to an increase in the value of produced products and conditional net profit. Fertilization systems enhanced the impact of crop rotation, with the greatest effect provided by the combined action of nutrient elements – a combination of mineral fertilizers, organic matter from predecessor by-products, and biopreparations.
