Ruso. В статье приведены данные по влиянию стандартных и комплексных удобрений на урожайность зеленой массы (листья, стебли, корзинки), сухого вещества, структуру урожая зеленой массы подсолнечника (высота растений, количество листьев на растении, диаметр корзинки) на дерново-подзолистой легкосуглинистой (Минский район Минская область) и связносупесчаной (Мозырский район Гомельская область) почвах.

In course of the research there were studied the influence of standard and complex fertilizers on productivity of green weight (leaves, stalks, baskets), dry substance and yield structure of sunflower (Helianthus annuus) (height of plants, quantity of leaves on a plant, diameter of a basket) on sod-podzolic light loamy (Minsk district, Belarus) and coherent sandy loam soil (Mozyr district of the Gomel region). As a result of realized research there was revealed that the level of increases of green mass of standard forms in doses of fertilizers in doses NPK 190- 300 kg/ha of a.i. on sod-podzolic light loamy soil was 18-45%, for coherent sandy loam soil - 13-43% compared with the control. Productivity of green mass of sunflower on light-loamy soil in variants with fertilizers ranged from 495 to 609 kg/ha, with a payback period of 1 kg NPK - from 7.6 to 18.4 kg, and coherent sandy loam soil - 471-598 kg/ha, with a payback period of 1 kg NPK – 6.5-15.8 kg.
