Abstract

The results of the effectiveness of the preparation "OrganitN" containing live bacteria of the genus Azospirillum zeae on yield and starch index are presented. The experiments were laid on sod-podzolic medium loamy soil, agrochemical indicators: humus content – 4.2%, pHKCl = 6.6; P2O5 – 1028 mg/kg; K2O-377 mg/kg. The scheme of the experiment included the following options: 1) control; 2) "OrganitN" consumption rate of 5L /ha, pre-sowing treatment by soaking tubers; 3) "OrganitN consumption rate of 5L/ha without pre-soaking tubers, irrigation method. Pre-sowing treatment of potato tubers of the "Reggie" variety with the drug has a positive effect on potato growth. The greatest effect of the preparation "OrganitN" according to the results of harvesting potatoes of the variety "Reggi", a reliable increase in yield (16.4%) was obtained in option 2 with a consumption rate of 5 liters / ha, by soaking tubers, the yield was 21.7 t / ha, the method of watering without soaking was less effective. Soaking tubers gives a more stable connection between bacteria and the rhizosphere of the plant. The presence of a more extensive number of nitrogen-fixing bacteria led to a high content of alkaline hydrolyzed nitrogen in the soil (190 mg/kg) compared to the control (136 mg/kg) and improved the nutritional regime of the soil. The activity of nitrogen fixers prolongs the growing season and affects the growth and formation of tubers. The use of the drug by soaking the seed material increased the yield of potatoes, also contributed to an increase in the number of tubers from one bush. Starch indicators are not increased. The use of bacteria in the agricultural sector will contribute to the improvement of the soil, increase the soil biota, achieve and create a quorum between them for joint action and the accumulation of soil organic matter
