Effect of superabsorbing polymers on potato yield

Climate change is leading to an increase in drought, which is the largest abiotic stress factor leading to a decrease in crop yields. One of the methods in solving this problem is the use of superabsorbing polymers (SAPs) (China, USA, Canada, India, Italy, Iran, Poland, Turkey, and others). The aim...

Description
Summary:Climate change is leading to an increase in drought, which is the largest abiotic stress factor leading to a decrease in crop yields. One of the methods in solving this problem is the use of superabsorbing polymers (SAPs) (China, USA, Canada, India, Italy, Iran, Poland, Turkey, and others). The aim of the research is to study the effect of using the superabsorbing polymers (cross-linked copolymer of potassium and ammonium salts of acrylic acid in the form of loose white granules) on the background of fractional-local application of mineral fertilizer to the crop formation. Field experience, accounting and observations were carried out in accordance with general requirements were used in our research. The studies were carried out in 2015-2017 on sod-podzolic sandy soil in the Lyubertsy district (Moscow region, Russia). When using superabsorbing polymers in an average of three years, the yield increased by 1.6...3.4 t/ha (5.5...Of 10.0%) for the studied cultivars; especially helpful was an early sort Meteor and a medium early variety Irbitskiy. It is possible to recommend the use of superabsorbing polymers at a dose of 200 kg/ha when growing potatoes in conditions of moisture deficiency.
