| Summary: | The results of determining more optimal and economically efficient system of mineral nutrition and the best predecessor for oats grown in the North Steppe of Ukraine have been considered in the paper. It’s been established that optimization of oats mineral nutrition helped to increase stem density on 0,7-6,5% in average. The plants grown after winter wheat possessed the highest quantity of seeds per panicle (31,8-43,0 p.). The grain variant N40P40K40 + N30 (top-dressing) + Reacom-SR-Grain (plant perfusion) possessed the largest grain weight after winter wheat, but the grain weight reduced after maize and sunflower. The best conditions for obtaining better yields occurred after winter wheat, when the plants showed better response to fertilizing. Due to introduction of N40P40K40 + N30 + Reacom-SR-Grain we received productivity increase on 13,9%. After sunflower the productivity increased on 9,0%, after maize on 8,9%. It has been also determined that the variant N40P40K40 + N30 + Reacom-SR-Grain gives the best profitability 128,7%. After maize and sunflower the plants need more doses of fertilizing and shows its profitability on 73,3% and 32,0% respectively. |
