Formation of oats productivity under the influence of mineral nutrition background and foliar dressing with preparation Izabion

Тhe investigations were conducted in the Tver region, on the sod medium sandy loam well cultivated soil, there were studied the features of formation of oats productivity under the influence of mineral nutrition background and foliar dressing with preparation Izabion (1 - effective fertility, 2 and 3 and NPK on 3.5 and 4.5 tons of grain per 1 ha). It was revealed that the greatest influence on the production process of oat plants was characterized the crops processing with working solution Izabion of 1.5% concentration in all mineral nutrition backgrounds (dose rate was 3.75 liter of the preparation in 250 l of water per 1 ha), held in the phase of tillering (23 microphase of BBCH code). This dressing provides a yield increase of grain of higher quality from 0.61 to 0.69 t / ha (from 17.5 to 34.1%) with a significant economic effect (from 1.56 to 2.04 rubles / ha). Raising of oat crop productivity is achieved by improving the photosynthetic activity of plants, strengthens the progress of the production process, improves the efficiency of PAR crops, optimizing the structure of the crop. It was also found that foliar dressing applications with the calculated doses of fertilizers (NPK) on the programmable productivity can increase the percentage of implementation of the program to 105.7 and 102.7% (at 86.5 and 87.3% without them).
