Abstract. In the Central region of the Non-Black soil area on soddy podzolic loamy sand soil in biologized crop rotation, a research
was carried out (2018-2019). The main objective was to estimate the efficiency of one-year lupine and white mustard as post-cut green
manure during winter wheat cultivation. On average for 2 years for winter wheat sowing with green basis and from roots remained peaces
20-28 dt/hectare of dry basis were implemented to soil. It contained 99-155 kg/hectare of plant food elements including 55-85 kg of nitrogen, 21-23 kg of phosphorus, and 23-47 kg of potassium. Low content of plant food elements was improved by applying mineral fertilizers to receive the planned grain yield of winter wheat (35 dt/hectare). Implementation of organic matter increased the activity of cellulosefermenting bacteria. The relative degree of cotton fabric mineralization boosted by 86 % to non-fertilized option and by 63 % to mineralized. In options with post-cut green manure together with mineral fertilizers was gathered the planned crop of winter wheat, an increase of crop was 17,7-18,4 (101-105 %) dt/hectare in comparison to standard and to fertilized soil 1,9-2,1 dt/hectare (6-8 %). Yield growth in options with postcut green manure together with mineral fertilizers was thanks to greater efficiency of an ear. It contained by 9-13 % more grains, its length increased by 8-10 % and grain mass from one ear by 19-25 % in comparison with mineral fertilized soil. Use of between-crop green manure as a post-cut one in biologized crop rotation reduced mineral fertilizers apply by 23-29 % .

FODDER QUALITY DEPENDING ON A COMBINATION OF FORAGE CROPS IN A CROP ROTATIONL.D. Frolova All-Russian Research Institute of Organic Fertilizers and Peat – a branch of the Federal State Budget Scientific Institution “Upper Volga Federal Agrarian Research Center,” ul.

Abstract. To assess fodder quality in crop rotations contained corn was conducted a field test on soddy-podzolic loamy sand soil in 2014 .
The test was conducted within 3 crop rotations: 1 – maize single-crop (control); 2 – annual grasses (oat + lupine) with complementary seeding of melilot – melilot – maize; 3 – white lupine – maize. Apply of mineral NPK fertilizers (30, 60, 90, 120) to maize single-crop (compared to options without fertilizers) increased fodder output by 29 dt/hectare (50 %), raw protein by 3,3 dt/hectare (78 %). Melilot and lupine as predecessors contributed to boosting of maize herbage and its better quality. When a dose of mineral fertilizers was increased, a yield of maize herbage, fodder units and assimilable protein increased as well. Compared to single-crop, an outcome of forage units and raw protein became larger when melilot was cultivated as a preceding crop by 17 and 21 %, lupine – 14 and 18 % respectively. Herbage yield grew by 18 and 27 % respectively. Mineral fertilizers and preceding crops had a positive impact on herbage quality. Its quality was in direct relation to yield and set of crops in the crop rotation. The greatest outcome of fodder units and raw protein on average provided a 2-field crop rotation – 7,0 and 8,7 dt/hectare, respectively. 1 fodder unit in a crop rotation based on maize single-crop contained at the average 58 gr, in 3-field crop rotation – 99 gr, 2-field – 98 gr .
