“…Physiological and biochemical processes occurring in plants are of great importance for the formation of the highest and highest quality potato crop. According to some researchers [10], 90-98% of the yield is created by photosynthesis, the main working body of which is the leaf surface, which was clearly demonstrated in our experience. Siliplant application increased the assimilative surface of potato leaves (Table 2).…”

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.

Abstract. The purpose of the work is to study the effect of the growth stimulant “Epin-Extra” on the photosynthetic activity of potato crops of the Nevskiy variety according to the results of field experiments. Methods. The studies of the tasks were carried out on the experimental section of the North Caucasus Research Institute of Mountain and Piedmont Agriculture – branch of the VSC of RAS in the conditions of the foothill zone of the Republic of North Ossetia-Alania according to generally accepted methods during 2019–2021. The soil of the experimental site is medium-powerful heavy loamy leached black earth, underlain by pebbles. Results. The results of the study indicate a positive effect of the use of the growth stimulant “Epin-Extra” in the cultivation of potatoes of the Nevskiy variety in the conditions of the foothill zone of the Republic of North Ossetia-Alania. The drug of the growth stimulant “Epin-Extra” contributes to an increase in the biometric indicators of potatoes: the height of plants by 1.4–3.3 cm, the number of main stems is 0.3–0.7 pcs. per bush compared to the control. It is established, that growth factor “Epin-Extra” strengthens process of formation of the area of leaves and keeps them during vegetation. On all skilled versions the area of leaves above a control version on 8.01; 4.54; 10.7 %, accordingly. The greatest sheet surface is noted at complex use of a growth factor in comparison with other skilled versions, the increase has made 8.2 and 6.0 %. The photosynthetic potential on skilled versions on the average varied from 1.32 up to 1.45 mln m2/ha days, which is 0.11; 0.19; 0.24 mln m2/ha days is more than the control option. The biological preparation “Epin-Extra” has a polyfunctional effect on potato plants. Scientific novelty. For the first time in the foothill zone of the Republic of North Ossetia-Alania it was the effect of the growth stimulator “Epin-Extra” on potato plantings was studied Nevskiy variety. Practical significance. The studies carried out make it possible to recommend the use of an effective growth stimulant “Epin-Extra” in the production of potatoes in the foothill zone in the pre-planting treatment of potatoes at a dose of 10 ml/t and when spraying plant leaves at a dose of 60 ml/ha in the budding phase, as an environmentally safe and low-cost agricultural technique that provides an increase in yield, the quality of potato tubers and resistance to late blight.

Abstract. The purpose of the work is to study the effect of the biological preparation “Bigus, VR” on potato crops, in order to increase the yield and quality of the resulting products in the foothill zone of the Republic of North Ossetia – Alania. Methods. Field trials in during 2020–2022 were carried out at the experimental plot of the North Caucasus Scientific Research Institute of Mountain and Foothill Agriculture – a branch of the Federal Center “Vladikavkaz Scientific Center of the Russian Academy of Sciences”, the soil of which is leached medium-power chernozem, according to generally accepted methods. Results. It has been found out that biopreparation “Bigus, VR” promotes the increase of biometric parameters of potatoes of varieties Farn, Nevskiy and Barna on all experimental variants in comparison with the control on the average: stem height – by 2–3 cm, haulm weight – by 65 g/bush, or 13,7 %. The highest coefficient of economic efficiency and yield of dry matter were observed in the variety Farn with preplanting treatment + spraying in the phase of budding – 0,75 and 9,7 t/ha with accumulation of 1,64 % of photosynthetic active radiation in the yield. The increase of the potato yield capacity on the average on the variants of experience is marked on the variety Farn – by 3,6 t/ha, or by 13,5 %; on the variety Barna – by 0,93 t/ha, or by 3,3 %, on the variety Nevskiy – by 1,9 t/ha, or by 7,3 %; starch – by 0,72; 0,25 and 0,55 %; dry matter – by 0,62; 0,42 and 0,43 %, respectively. Costs are recouped in all variants of the experiment compared to the control. Scientific novelty. For the first time in the forest-steppe zone of Republic of North Ossetia – Alania we studied the possibility of using a new generation biopreparation “Bigus, VR” on the potato varieties Farn, Barna and Nevskiy. Practical significance. On the basis of the results of the research in the production of potatoes in the piedmont zone of RNO-Alania can be recommended the use of the biological preparation “Bigus, VR” on potato plantings as a rational and highly effective agrotechnological method.
