Effect of the Biostimulator Composition with Trace Elements to Accelerate the Growth and Increase the Productivity of Pumpkin

The use of environmentally friendly growth regulators and micro fertilizers makes it possible to use energy-saving technologies and maximize the physiological capabilities of plants. At the Institute of Plant Chemistry named after Academician S.Yu. Yunusov, a biostimulator Uchkun was created, which has a low consumption rate and low toxicity. The drug increases the yield of many crops (cotton, wheat, etc.) and protects them from adverse conditions, increases the content of photosynthetic pigments in the leaves. The purpose of this work is to study the effect of pre-sowing treatment of pumpkin seeds of the Spanish-73 and Palov-Kadu-268 varieties with the Uchkun biological preparation and its composition with trace elements (Uchkun plus preparation) on the productivity and quality of seeds. It is shown that this composition contributed to an increase in crop productivity. When treated with the composition, the average weight of one fetus was 3.4 kg and exceeded the option without treatment (control) (2.8 kg) by 21.4%, when treated with a biostimulator Uchkun – 3.3 kg, which was 17.8% more than the control. The average increase in pumpkin yield during pre–sowing seed treatment with Uchkun plus was 10.1 t/ha compared to the control, whereas when exposed to Uchkun – 7.8 t/ha. In addition, it was shown that when exposed to a complex preparation, the quality of pumpkin seeds improved, the oil content and the total protein content increased, and the amount of unsaturated fatty acids increased.
