Аgronomical assessment of efficiency of introducing various fertilizer doses for the crop rotation cultures

On the sod-podzolic medium-loamy soil of the Vologda region, the calculated fertilizer systems have increased productivity by 30-94% on average for 3 years of the research compared to the no-fertilizer option, by 33 - 49% compared to the sowing fertilizer (for cereals and annual crops and applying fertilizer when planting for potatoes). The use of fertilizers provided a high cost of 1kg of active material by productivity gains of all studied crops, and for the research years there has been the highest cost - 23 kg of fodder units. The calculated doses of fertilizers have differed in cost.

The influence of fertilizers on the removal of nutrients by crop rotation in the Vologda region

The productivity of crop rotation on soddy podzolic loam soil in the stationary experience during 2015-2017 was high in the conditions of the Vologda region, especially among annual crops. Winter rye and potatoes also differed by consistently high yield and productivity during the years of research. All the studied cultures showed good responsiveness to fertilizers, especially the calculated doses of their application. The average productivity of crop rotation was 3.30-6.34 tonne cu / ha.

The efficiency of foliar dressings with nano-preparations in increasing the productivity and stability of potatoes to diseases and weeds

As a result of complex investigations conducted in the Tver region in 2013-2015 on well-cultivated soddy medium podzolic sandy loam soil the peculiarities of forming bio-resistance and productivity in three potato varieties (Lyubava, Krasavchik, Nikulinskiy) under the influence of foliar dressings with AgBion-2 and NanoGro preparations having different working liquid concentrations have been studied.

Prospects for integration development in potato as the northwestern federal district of the russian federation (on the example of Leningrad region)

Trends of potato production in the Russian northwestern federal region over the past ten years have been studied. A comparative analysis with national figures has been also conducted in the work. The hypothesis is that the growth of income and the labor intensity of potato production in the private sector cause the potato production decline in the region and in the country. In this regard, it has been proposed for farms with dairy specialization to produce potato as the main activity in the conditions of the Russian north-west federal region.

Yield, quality and profitability of potato tubers production in the application of fertilizers and chemical means of protection on sod-podzolic medium loamy soil

In the conditions of a field experiment on soddy-weakly podzolic medium loamy soil of the Vologda District, Vologda Region, the effect of applying fertilizer, ‘Lazurit, SP’ herbicide and ‘Albit’ complex preparation on yield and tuber quality of ‘Scarb’ table potato variety has been studied. Their combined application improved the marketability of the tubers, increased the starch content, and reduced nitrates. The profitability of potatoes production has been calculated in current prices of 2017.
