EFFICIENCY OF CHEMICAL FUNGICIDES AGAINST LEAF TAN SPOT OF WHEAT

abstract 1121508011 issue 112 pp. 153 – 162 30.10.2015 ru 1536
In recent years leaf tan spot had dominated into pathogenic complex of wheat in southern Russia. The causative agent of this disease is hemibiotrophic ascomycete Pyrenophora tritici-repentis (Died.) Drechsler; imperfect state of Drechslera triticirepentis (Died) Shoem. It causes two different symptoms in susceptible wheat varieties: chlorosis and necrosis. Under epiphytotic disease progression crop losses can achieve 65%. One of the most important elements of phytosanitary control of wheat cenosis is scientifically relevant chemical fungicides application. Biological efficiency of some fungicides against Pyrenophora tritici-repentis has been estimated. Research was conducted on the experimental ground of FSBSI ARRIBPP on the variety susceptible to the pathogen – Krasnodarskaya 99. Preparations were tested one time at leaf-tube formation (Z37) phase or two times: at leaf-tube formation (Z37) and start of heading (Z51) stages. Double treatment was more effective than a single one. Fungicides “Amistar extra” and “Prozaro” have got the high biological efficiency – 80,7 and 83,7%, consequently, and longer protective period (up to 40 days) in comparison to every tested fungicides

EFFICIENCY OF CULTIVATION OF DIFFERENT WINTER WHEAT CULTIVARS IN THE CONDITIONS OF THE WEST CAUCASUS

abstract 1231609081 issue 123 pp. 1152 – 1181 30.11.2016 ru 677
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of two winter wheat cultivars (Lira and Krasnodar 99) was investigated. The investigations were carried out in the North-Kuban Agricultural Experiment Station in two five-crops: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content, depending on the power of nutrition backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. Grain quality was generally determined by the dose of fertilizer. High and higher doses of fertilizers contributed to the protein content from 11.7 to 12.3% and fibrin content - 23,5-24,0%. A strong correlation between yield and agronomic methods was determined

EFFICIENCY OF CULTIVATION OF DIFFERENT WINTER WHEAT CULTIVARS IN THE CONDITIONS OF INSUFFICIENT HUMIDIFYING IN THE KRASNODAR REGION

abstract 1201606088 issue 120 pp. 1322 – 1336 30.06.2016 ru 688
The influence on the predecessor, on the time of sowing and various mineral nutrition levels, on the productivity of seven cultivars of winter soft wheat of Krasnodar Agricultural Research Institute selection was investigated. On the basis of the obtained experimental data and production audit it was found that all studied cultivars under the total complex of cultivation technological methods are able to form the yield of 6-7 t / ha with the payment of one kg of active ingredient of fertilizer by the grain within 6.50-9.86, and 8.56- 10.71 kg. Soil was ordinary chernozem with a low humus content powerful humus content, depending on the power of backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, mobile phosphorus is 22,4 - 26,6 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. Predecessors are winter wheat, sunflower, white mustard cultivated on seeds. The main tillage is resource-saving with the mulching of 0-10 cm layer. Studied sowing terms are the 20th of September, the 1st and 10th of October. The backgrounds of mineral nutrition: 1-without fertilizer N0P0К0; 2-minimum dose of complete mineral fertilizer N60P30К30; 3-average dose N90P60К60; 4-high dose N120- 160P90К60. Seeding rate is 5 million germinating seeds per hectare. The objects of the research were seven winter soft wheat cultivars of Krasnodar Agricultural Research Institute selection. We studied winter wheat cultivars with different combination of biological characteristics and predecessors. This combination is contributed to the yield growing from 4,26-5,82 t / ha up to 6,97-7,2 4,26-5,82 t / ha with the payment of one kilogram of active fertilizer substance with the output of grain within 8,52-12,0kg

EFFICIENCY OF DIFFERENT METHODS OF USING THE NON TRANSDUCING E. COLI BACTERIOPHAGES FOR PROPHYLAXIS OF POST-WEANING DIARRHEA OF PIGS

abstract 0781204060 issue 78 pp. 763 – 774 30.04.2012 ru 1975
The influence of four experimental phage preparations, designed based on non-transducing E. coli bacteriophages on pigs with post-weaning diarrhea studied. The influence of these phages in depending by methods of its applying (per os and intra cutis) on coli-titer and coli-phages titer studied. It is established, that the best survival rate and the clinical condition showed animals treated with the E. coli phage T4-type with lab. number «8» (till 5,52 lg CFU/g at 37-days age) in parallel with an increase in titer of phages (till 5,73 lg CFU/g at 40-days age). Intradermal (intra cutis) method of applying of experimental phage preparations (constructed on basis of phage “6” and phage “8”) showed the some positive effects on correction of negative dynamics of coli-phages titer in control group

EFFICIENCY OF FERROURTIKAVIT BIOLOGICALLY ACTIVE ADDITIVE APPLICATION IN THE DIET OF BLACKMOTLEY BREED LACTATING COWS

abstract 1271703050 issue 127 pp. 733 – 744 31.03.2017 ru 546
Ferrourtikavit is a biologically active additive (BAA) derived from common nettle supplemented with micro nutrient elements (titanium, vanadium, molybdenum, zinc, copper, iron, tin, chromium, manganese, barium). Ferrourtikavit is manufactured from local vegetable raw materials, however its application in feeding dairy cows is not sufficiently studied. Therefore, the application of the BAA ferrourtikavit in animal feeding with a view to increase milk production is relevant. The aim of the research conducted is to investigate the impact of the BAA ferrourtikavit on the overall nutritional value of animal diet and reduction of food consumption. The experiment was conducted on four groups of black-motley breed dairy cows. Formation of the experimental groups (15 animals per each group) was performed on the third lactation, taking into account age, productivity during the previous lactation, breed characteristics, live weight. The main diet consisted of hay, haylage, succulent fodder, concentrates. Additionally to basic diet the 2nd , 3 rd and 4th experimental groups obtained the BAA ferrourtikavit at the doses of 0,25, 0,50 and 0,75 mg/kg of live weight, respectively. It has been established that the animals from the experimental groups (2nd, 3rd and 4th) consumed 43,9-51,3 energetic feed units less, 439,4-513,5 MJ metabolic energy less, 56,4 – 62,0 kg dry matter less, 1,1 – 1,6 kg digestible protein less. The lowest feed consumption was noted among the animals from the 3rd experimental group, in the basic diet of which the BAA ferrourtikavit in an amount of 0,50 mg/kg of live weight was introduced. The research conducted established, that application of the biologically active additive ferrourtikavit in the diet of lactating cows at the dose of 0,5 mg/kg of live weight led to the highest milk yields 4678±45,17 kg. In the experienced groups, increase in milk yields, decrease in concentrates' utilization as well as costs of 1 kg milk as compared to the control group were registered

EFFICIENCY OF SELECTION ON HIGH TILLERING AT VARIOUS DENSITY OF PLANTING OF RICE PLANTS

abstract 0641010018 issue 64 pp. 225 – 234 22.12.2010 ru 1825
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
