INFLUENCE OF BALANCED DRUG MIXTURES ON YIELD CAPACITY AND QUALITY OF POTATOES TUBERS
The effect of plant growth biostimulant (rut Most), a balanced mixture (Leyli 2000) and insectofungicide (Emesto Quantum) on the yield and quality of variety “Udacha” potato in the peasant farm of Vasilyeva Venera Andreevna in the Krasnoarmeysky district of the Chuvash Republic was studied. Studies have shown that the highest potato crop was formed during digging on August 21 in the experiment using Rut Most + Leyli 2000 + Emesto Quantum preparations. The yield in the variant using these preparations was 40.6 t /ha, which is 16.0 t /ha higher compared to the control variant. The results of the studies conclusively prove that the processing of potato tubers before planting with RootMost + Leyli 2000 + Emesto Quantum helps increase the starch content from 18.7 to 19.5%, which is 0.8% higher compared to the control version. During the research it was found that in the period from 01.08 to 03.09. In 2018, the rate of accumulation of dry matter in potato tubers increased with the use of drugs. Its highest content (23.8%) was recorded during their use, which turned out to be 0.7% more compared to the control variant. An equally important indicator on which the consumer value of potatoes depends is the amount of nitrates contained in it. It turned out that when processing tubers before planting with RutMost + Leyli 2000 + Emesto Quantum preparations, its amount increases to 50 mg / kg. It is important to note that, as the tubers ripen, the quantitative content of nitrates markedly decreased and, depending on the experimental options, was 80.0-197.3 mg/kg.
