The results of immunological assessment of winter wheat varieties included in the State register of breeding achievements of the Russian Federation and the variety of different types of resistance to yellow leaf spot pathogen are presented in this article
In the article, the data of researches of studying of elements of technology of cultivation of winter wheat, taking into account its high-quality features, types of fertilizers and application, joint crops with winter vick provided in the Rostov region, and also the economic assessment is given
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches of agriculture, economics of agricultural enterprises in whole as well. In article the method of calculation of sufficient balance soil is considered.
The positive effect of soybean oil meal in combination with biologically active substances on productivity and meat quality was determined in the experiments with young pigs
In the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
The article contains data of the phyto-sanitary status of vineyards in Russia. The dominant pests and trends in species composition of entomofauna patosystems of ampelocenosis are represented
The introgression of race-specific blast resistance genes Pi-ta, Pi-b, Pi-z into genotype of Russian rice variety has been performed by backcross method with marker control of donor alleles. Plants that demonstrated maximal similarity with recurrent parental form, the short vegetation period and abundant panicle fertility have been picked up from BC3-population.
Marker analysis of developed population revealed the samples carrying introduced target genes in homozygote state
In the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids
The article presents a comparative analysis of the results on available phosphorus measurements in common black soils using the Machigin and Olsen methods. The relationships between maize productivity and soil available phosphorus and also between
phosphorus concentrations in the above-ground plant parts and soil available phosphorus were identified at various stages of crop development
Value of new linear sorts allocated by the method of analytical selection from sort Stepnaya 7 in increase of adaptability of winter soft wheat is discussed. The new linear sorts: Line 15, AMMA, Line 21, Line 11, Line 26, Line 29, Line 36, Line 37 revealed combination of stability to brown and yellow rusts. Productive varieties with high quality of grain: Magnificent, Line 12, Line 38 have shown stability to a brown rust and poorly affected by other mushroom diseases
