The problem of conservation and reproduction of soil fertility by using unconventional organic fertilizers, particularly the replacement of the mineral nitrogen fertilizer to its organic form is discussed. The growth of the livestock industry lays the groundwork for the recovery of meat processing industry waste of horned ungulate crumbs (HAC) as fertilizer for inter-tilled crops. HAC contains about 14% nitrogen. Experiments on the application of HAC as a nitrogen fertilizer and sorption-type ameliorant – zeolite-containing tripoli were organized in 2012-2016 in the crop rotation link on the light gray forest soil of the experimental field of the FSBEI HE Chuvash State Agricultural Academy, Chuvash Republic. In this paper, the effect of the HAC-form on the optimization of nitrogen nutrition of the studied crops both separately and for tripoli having phosphorus-potassium mineral fertilizers is studied. The positive effect of HAC and tripoli on the growth and development of potato and fodder beet plants, soil biological activity, leaf surface area, yield and quality indicators of potato tubers and fodder beet root crops both in the first year when fertilizers are applied and in their aftereffect in the second year for barley yield was revealed. The study materials contribute to the practical solution of the problem of the recovery of meat processing industry waste and rational use of resources in the fertilizer system, being a guide to energy and resource conservation in agriculture.
The article presents three-year data on the productivity of spring durum wheat varieties in the European continental climate, in order to select the most promising of them and determine the possibilities of breeding and technological adaptation in the region. The experiment involved five varieties of spring durum wheat as B 200, B 205, B 209, B Niva, and Luch 25 taken from Russian Middle Volga regions. Indicators of the best productive bushiness were noted in varieties B Niva and B 209. It was found that the number and weight of seeds in the ear, depending on the variety, varied proportionally to the length of the ear. The best indicators of the structure of the crop were established in varieties B 209 and B Niva. The weight of 1000 seeds was 42.32 to 53.3 g for different varieties of durum wheat. Taking into account the biological yield, the advantage of the variety B Niva over the control variant was revealed. The best formation of grain gluten was observed in agroclimatic conditions in 2015 and 2016: for three years the best indicators of gluten was on average 30.4 %and 29.95%, respectively, for varieties B Niva and B 200.

The article deals with the formation of the area of leaves of spring wheat depending on the treatment of seeds and varieties in the conditions of the Chuvash Republic. Three varieties of Margarita, Simbircite, and Prokhorovka were studied. The second factor is seed treatment in three gradations: 1. Without processing (control). 2. Seed treatment with the drug Benlate. 3. Seed treatment with Nano-Gro. The results of the analysis of leaves area formation are presented. Determining the optimal leaves area is a very complex problem. Solar radiation at an insufficient leaves area of field plants is absorbed not completely; at the greatest developed leaf surface the same phenomenon occurs. In combination with the seed protectant of spring grain crops – Benlate, the authors also studied the effect of Nano-Gro. The presowing treatment of seeds with the Nano-Gro solution significantly affects the increase in the formation of the leaves area of spring wheat.
The article presents data on the study of the effect of varietal characteristics of potatoes on the formation of yield and quality of tubers. The aim of the work was to identify the best varieties of potatoes for cultivation in Nizhny Novgorod region. For conducting research, the following methods were used: experiments at cultivation, storage, use of potatoes, laboratory studies, tasting evaluation, and ranking. The effect of tuber damage by common scab and rhizoctoniosis on the safety of potato tubers was revealed. It had been established that all varieties of potatoes in conditions of highly cultivated sod-podzolic soils form a high yield of tubers. The maximum yield provides cultivation varieties Crystel and Sandrine. Crystel and Sandrine Varieties were characterized by a maximum yield of marketable tubers and weight per tuber. They also had the high starch content in tubers, the maximum tasting and overall assessment of tubers. It was noted that tubers of all varieties were slightly affected by common scab and rhizoctoniosis, which had a positive effect on their ability to work. To a lesser extent, these diseases affected the tubers of the varieties Crystel, Sandrine, and Serafina. The quality of these varieties was at the level of the standard.
