Leaf pigment content and accumulation of dry matter by potato plant as affected by sulfate fertilizer in green house experiment

Nagornyy V.D., Nourouson Arimalala R -.


From the time mineral fertilizers were used single superphosphate have been the main source of phosphate in plant nutrition. This fertilizer contains nor only 19-21% of P2O5 but also sulfate in form of gypsum and small amount of sulfuric acid. As a result, application of one kg of superphosphate enriched the soil with 80-100 g of sulfates. During last 40-50 years single superphosphate was replaced by concentrated mineral fertilizers which contain up to 42-52% of P2O5. And now on some soils the main source of sulfurbecome precipitations which bring sulfur oxides produced by chemical enterprises and exhaust fumes of machinery. As a consequence of this there are not rear cases when growing plants, and more often legumes, oil and root corps, show signs of sulfur deficit. Optimal levels of sulfur content in plant leaves well established. But there is obvious interest to get more objective data on physiological processes which are more sensitive to deficit of this plant nutrient and on preferable time of sulfur application. Influence of sulfate and other anions of potassium fertilizers on leaf pigment content and accumulation of dry matter by potato plants are presented and discussed in the article.

The efficacy of insecticides against Psylla Pyri L. in the conditions of the 2013-2015 ccr

Skryljov A.A., Kashirskaja N.J.


One of the major pests of pear is a pear psylla (Psylla pyri L.), which in large amount, can cause the death of pear plantations. Currently assortment of preparation approved for application in pear plantations, does not provide effective protection against the pear psylla. In the conditions of growing seasons 2013-2015, the preparations Actara WG (250 g/kg), Dimilin, WP (250 g/kg), Vertimek, EC (18 g/l), Decis Profi, WG (250 g/kg), Bi-58 New EC (400 g/l), Calypso, SC (480 g/l) were tested on pear plants varieties Osennaya Yakovleva to protect against the massive spread of pear psylla. Preparations were applied as well univariate as in tank mixtures. Monitoring weather conditions and analysis of pear psylla’s development during the growing season let to reduce the pesticide load in the plantations of fertile pear and increase profitability pear fruit production. Depending on weather conditions and the degree of development of the pest, used insecticides showed different efficiency. The highest expansion and development of pear psylla were occurred by the weather conditions in 2014 and 2015 (the optimum temperature and humidity, low rainfall); unfavorable for pest development was 2013 (frequent and abundant precipitation). The Most long-term biological effectiveness to control pear psylla, regardless of weather conditions, achieved through the application of a tank mixture Dimilin, WP + Actara, WG (biological efficiency = 85-98%). High biological efficiency of Dimilin, WP, Actara, WG and Vertimek, EC univariate (BE = 78-95%) was achieved by applying them at a low number of pear psylla.

Savich V.I., Belopukhov S.L., Kotenko M.E., Gukalov V.V., Ilicheva P.I., Fedorova T.A.


It is shown that the mineralogical composition of the soil is a factor when considering the lithology of soil at a lower hierarchical level. The mineralogical composition and determines the content ratio in the soil of nutrients and toxicants, ion exchange processes, soil resistance to degradation of soil fertility. It is the matrix of the formation of soil and regulates the transformation, migration and accumulation in soil of substances, energy and information of environmental and human impact.

Soil-ecological characteristic of the Forest experimental station of Russian State Agrarian University of Moscow Agricultural Academy by K.A. Timiryazev under plantings in the conditions of various anthropogenous loading

Dovletyarova E.A., Mosina L.V., Petrovskaya P.A.


The heavy metals circulating in the biosphere have a huge negative impact on ecosystem components. At the same time however, the real danger from the environmental pollution by the heavy metals (HM) is constituted not by gross volume of metals, but by their mobile forms as the last practically define the accumulation of elements in biomass and influence the biological activity of soils. Meanwhile, the level study of this question is very weak. The influence of soil consolidation on HM mobility is almost not unknown. In this regard at wood sites with unequal anthropogenic loading we have conducted researches which have demonstrated the dependence of toxic heavy metals forms, diverse by durability of communication, on the consolidation of soil. In many respects the density of soil profile defines the formation of the soil modes - water-air, temperature, oxidation-reduction, biochemical, and often makes decisive impact on demonstration of the soil main ecological functions, conditions of growth, development and efficiency of plants, microorganisms activity and soil fauna.

Sisyagin P.N., Redzhepova G.R., Sisyagina E.P., Leonteva I.L.


The possibility of use of phytomedicine in conjunction with hyperimmune serum of animal donors to enhance the preventive effectiveness at mixed respiratory infections in calves was studied. In a farm in Nizhny Novgorod region with unfavorable in terms of mixed respiratory infections of viral and bacterial etiology a high level of morbidity (80%) and mortality (26%) was revealed. Before use of medicines in clinically healthy calves aged 20-30 days mild immunodeficiency was found characterizing by decrease in relative T-cell content by 20.0%, functional activity of blood neutrophils in spontaneous and induced tests by 19.0%, lysozyme activity by 29.0% when compared with minimum value of the physiological norm for this age period. On the background of the immunological imbalance drastically decreases the effectiveness of traditional therapies. Use of Maxophyt in conjunction with hyperimmune serum of donor animals promoted statistically significant rise in initially reduced immunological parameters and intense specific immunity in clinically healthy calves: absolute and relative T- and B-cell content increased by 36.0%, 38.0% and 50.0%, 67.0% respectively, functional activity of blood neutrophils in spontaneous and induced tests by 18.0% and 32.0%, IgG and IgM levels by 46.0% and 53.0% respectively, lysozyme activity of blood serum by 60.0%. Subcutenous injection of hyperimmune serum of donor animals in conjunction with aerosol treatment with phytomedicine Maxophyt enhanced the preventive effectiveness at mixed respiratory infections of viral and bacterial etiology to 96.2% which was 21.2% higher when compared with the control and average daily body weight gain to 890.0 ± 22.8 g which was 26.0% higher when compared with the control. Combination of medicines provided the 100% safety of calves in experimental groups which was 8.3% higher when compared with the control. The course of disease in experimental calves was mild.
