Study of the effect of foliar top dressing with liquid polymer fertilizer Zelenit nitrogen micro on the growth and development of potato plants in vivo

Abstract

This article contains the results of a study on the study of foliar feeding of potatoes with liquid polymer fertilizer Zelenit nitrogen micro at concentrations of 25, 30 and 35 mg/l. The provision of the plant with the main elements of nutrition contributes to good growth, accelerating its development, and also has a positive effect on the resistance of plants to negative influences. In the course of our research, it was found that it is effective to use foliar top dressing with Zelenit at a concentration of 30 to 35 mg / l, here the plants were better leafy and had the largest number of stems, which had a positive effect on the formation of the crop. The most productive of the studied varieties was the Belarusian variety Manifest, which ultimately had the maximum yield of seed material of the first field generation, which plays a paramount role for seed production. When studying the average coefficient of adaptability (Ka) in the conditions of the Pskov region, it was found that the most productive and promising varieties for growing in this region are Manifest and Lileya Belorusskaya with the highest coefficients of adaptability from 1.25-0.02 and with the use of liquid polymer fertilizer at a concentration of 25-30 mg / l.
