On July 20, a seminar was held at the farm of Valery Cherenkov in the Pervomaisky district, where the farmer demonstrated to his colleagues the production of virus-free planting stock for potatoes of higher reproductions, the Svetich news agency reported with reference to the regional ministry of agriculture.
Valery Cherenkov's farm is one of the largest in the region, engaged in seed production of domestic selection potatoes based on biotechnological approaches - a virus-free planting material.
The technology for seed production here has a full cycle. The first step is the greenhouse cultivation of minitubers from special test tubes. In the greenhouse, the farmer places 400 test plants, of which five years later he grows 400 tons of seed potatoes. (In the near future, Valery Cherenkov, along with tube technology, intends to replicate the cassette, which gives 100% survival of plants). After receiving the minitubers for the next season, they plant in the field to obtain super-super-elite seeds, which are subsequently propagated into super-elite and elite.
Using this technology, the farmer produces seeds of four varieties of potato of Siberian selection.
Seed is grown on 30 hectares, where elite, superelite and super-super elite planting material is obtained. The farmer does not use mineral fertilizers, but practices a system of green manure. “Usually in the autumn we sow winter wheat, in June of the following year after the green mass is formed, we mow it and plow it into the soil, produce another sowing of pea-oat mix, which we also mow and plant in the soil in autumn. Along with the rejection of mineral fertilizers, we do not use herbicides. Weeds are controlled by a crop rotation system and mechanically. We carry out at least four such treatments before planting potatoes, ”said the farmer.
Received elite potato seeds on the farm are stored in a potato storage capacity of 400 tons, equipped with modern ventilation and cooling systems. A line was also installed for washing, drying and packing seeds and marketable potatoes and carrots, which the farmer cultivates in small areas with the aim of replenishing working capital during the harvesting season.
According to the agrarian, the topic of varietal change and varietal renewal in potato growing in recent years is gaining momentum. “Potato growers have now begun to pay great attention to the quality of seed material and are aware that the final crop depends on it. The topic of elite seeds is interesting for us, seed growers, and farms that buy seeds, as state support is provided for these purposes, ”says Valery Cherenkov.
Every year, the farmer is ready to sell at least 300 tons of planting material of higher reproductions.
Note that as part of hectare subsidies this year, increased rates have been introduced for seed potato farms. In the production of elite potato seeds, a rate of 27800 rubles / ha is provided. Also, agricultural producers buying elite seeds (zoned in the Siberian Federal District) per hectare of occupied space can receive compensation of 16000 rubles.
