DescriptionThe influence of the predecessor and different doses of mineral fertilizers on the yield and the quality of the winter wheat cultivar ‘Krasnodar 99’ were investigated. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten- course crop-rotations: grain plowing and grain - grass plowing (stationary experience). The soil is the black soil, low in humus, powerful, with humus content 3,95-4,00%, depending on the nutrition in the arable soil layer (0-30sm), mineral nitrogen is 5,9-8,3 mg / kg of soil, 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. The protein content was mainly determined by the fertilizer dose. Enhanced and high doses of fertilizers contributed to an increase in the protein content to 12%.A strong correlation between protein content, agronomic methods and precipitation was determined

DescriptionThe article is devoted to the various elements of the cultivation technology of winter wheat called Antonina with the application of different soil fertility backgrounds, fertilizer norms, and plant protection systems against weeds, pests and diseases. Investigations are carried out in a multivariate stationary experiment: factor ‘A’- soil fertility; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - medium (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil tillage: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. Based on examined researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased, by that, the high quality of the grain is provided

DescriptionThe reaction of winter wheat of Krasnodar Agricultural Research Institute selection that is included in the State Register of selection achievements in the Russian Federation, on the predecessor, the sowing time and the level of mineral nutrition in 2008 - 2010 was studied in "Severokubanskaya agricultural experimental station" P.P. Lukyanenko Krasnodar Agricultural Research Institute, located in the northern area of the region. The objects of research were cultivars ‘Bezostaya 1’, taken as a standard, ‘Tanya’, ‘Grom’, ‘Sila’, ‘Ligue 1’, ‘Irishka’ and ‘Yumpa’, with a specific weight of strong wheat (excluding the cultivar ‘Bezostaya 1’) - 57.1%, essential - 28.6%, weak - 14 3%. The predecessors are winter wheat, sunflower, white mustard. Seed dates: the 20th of September (optimal for determining the originator of the cultivar) the 1st and 10th of October. The background of mineral nutrition is N0P0K0, N60P30K30 and N120-160P90K60. The soil is an ordinary powerful heavy-loam chernozem with humus content in the soil layer 0 - 30 cm 3.95 - 4.00%, of mineral nitrogen - 8.3 - 10.7 mg / kg of soil, of mobile phosphates - 22.4 - 26 6 mg / kg of soil, of exchangeable potassium - 330 - 360 mg / kg of soil. Weather conditions during the research were extremely contrasting, both by the precipitation and by the temperature conditions. Based on these studies, it was found that five or six cultivars of this crop that differ in biological and economic features, the reaction on the predecessor, soil fertility and sowing terms as well as adapted to the specific soil and climatic conditions should be used to obtain consistently high yields of winter wheat. Well-chosen cultivars, predecessors and sowing terms predecessors allow without additional cost on the unfertilized background to increase the yield on 0.20 - 0.79 t / ha. Together with the growth of yield, the technological quality of grain is improved: protein content by 0.5 - 2.4%, fibrin content - 1.7 - 7.6%. The principle of mosaic use of cultivars with specific predominance of strong wheat is 57.1%, essential - 28.6%, weak - 14.3%, it allows to produce the grain when you apply the minimum dose of 12.5% protein content, 20.9% of fibrin content. When using N90P60K60 respectively 13.3 and 23.6% at a dose N120-150P90K60 - 14.4 and 26.8% with an average of 13.5 - 24.0%

DescriptionThe influence of different agricultural technologies on the yield of winter barley variety ‘Gordei’ was studied. Economic evaluation was given to the researched factors. The studies were carried out at the experimental station of Kuban State Agrarian University in the conditions of polyfactorial long-term soil monitoring. The soil is represented by strongly leached, light-clay black humus with an average thickness of the humus horizon - 150 cm. It was found that with the change of technology (fertilizer, tillage, sowing method, means of protection) winter barley yields increases to 50% in comparison with the control. According to the analysis of bioenergetic and economic evaluation it makes sense to use the variants 022, 111 and 222 at plowing, where the maximum net efficiency ratio and net income are noticed

DescriptionThe stage of introduction of plantlets to in vitro culture is an important stage of technology of clonal micropropagation of plants. For the purpose of decrease in a share of the plantlets that were lost from an infection and increase of their regeneration ability, sterilizers and antibiotics, effective and safe for apple rootstocks’ plantlets wee allocated, and also favorable terms of introduction to in vitro culture were allocated. As a result of the conducted researches, we have established that on influence on an nutrient medium and plantlets infection and on growth and development of plants, beneficial effect on apple rootstocks’ plantlets has an antibiotic nystatin of 200 mg/l: the reproduction coefficient on the medium with this antibiotic is equal 4,3, in the same concentration nystatin has the sanifying effect of 60-75% for stocks of SK 2 and MM 106. During researches of sterilizers for apple rootstocks’ plantlets SK 2, SK 3, SK 4, SK 7, MM 106 as an alternative to widely applied highly toxic sterilizer corrosive sublimate (the first class of danger) were picked up effective and safe preparations for sanitation of plantlets from an infection, such as the household preparation "Whiteness" (sodium hypochlorite) in cultivation 1:2, low-dangerous substance of the fourth class of danger (a share of viable plantlets of 75,5% from initially introduced), and also fosfopag, a preparation of the fourth class of danger (a share of viable plantlets of 65% from initially introduced). The favorable term for a meristem of apple rootstocks’ plantlets’ introduction to in vitro culture are phases of buds’ burgeoning (March) and the intensive growth of shoots (May – June)

SUCCESSFUL APPLICATION OF SIGNS OF HEAT INDEX IN MAKING PROGNOSIS FOR EMBRYO DONOR COW PRODUCTIVITY
06.00.00 Agricultural sciences
DescriptionThe researches of the quality of 34 donor cows estrus detection during superovulation induction period, after Pg F2α injections were carried out. The clinical heat index was set up and applied. The clinical heat index is clinical prognostic criterion of successfulness of superovulation induction and embryo productivity. It was shown that donor cows showing signs of oestrus during 48-72 hours after Pg F2α injections had the best embryo collection qualities while certain increase of degenerated or aborted embryos and unfertilized oocytes is determined in embryo collections from cows showing signs of oestrus before or after that period
