Application of Siliplant in the technology of growing potato minitubers in protected soil conditions

Under greenhouse conditions the effect of silicon-containing preparation with complex action, capable of simultaneously stimulating plant ontogenesis, photosynthetic processes and increasing the productivity and quality of plants was studied. The purpose of this study was to study the effect of the silicon-containing preparation Siliplant on the productivity and quality of minitubers of early maturity potato varieties Vineta in the system of virus-free (original) potato seed production. Results demonstrated that Siliplant causes an increase in biometric and physiological parameters such as plant height (by 5.7%), the number of stems in the bush (by 30%), weight of roots (by 16.7%), leaf area (by 23.7%), net photosynthetic productivity (by 37%) compared with the control variant.Root treatments with the preparation increased the yield by 19.3 % and the multiplication factor by 20.0 % compared to the control. Also, the use of Siliplant contributed to a slight increase in quality indicators (17.7 - 2.5 %), respectively, compared to the control. Thus, the use of Siliplant in the double root treatment of potato microplants in protected soil conditions is a promising agricultural technique in the conditions of Nizhny Novgorod region, allowing to increase the productivity of photosynthesis, yields and its quality
