FORMATION OF CROP ROTATION PRODUCTIVITY DEPENDING ON FARMING SYSTEMS AND FERTILIZERS

Studies have shown that winter wheat is the most favorable predecessor for growing oats, providing the highest growth and yield. The best results were obtained with an integrated approach to nutrition, including basic fertilization with N50P50K50, nitrogen fertilization with N30 and treatment with Reakom Plus SCU. The maximum parameters, in particular panicle length (22.3 cm), grain weight (1.23 g) and weight of 1000 grains (26.1 g), were observed after winter wheat. Sunflower was the least favorable predecessor due to poor soil conditions, even with optimal nutrition. The use of integrated systems that combine mineral fertilizers and biostimulants allowed to achieve the highest oat yields (3.43-3.60 t/ha) after winter wheat and corn. This emphasizes the importance of the correct choice of predecessors and an integrated approach to nutrition to increase the productivity of oats in modern agriculture.
