The behavior, interior and milk yield of the mature Black-and-White cows with various productivity levels, as well as etology of the replacement heifers are researched. The superiority of the high milk yielding cows for the lying duration and eating feed and water is revealed. Reduced variability of vital behavioral actions of animals is found. In addition, high yielding cows has been lower variability in all feeding acts. It was noted that high yielding animals exceeded equal age cows by the level of most interior factors. The differences were significant on the content of hemoglobin, vitamin E, and especially on the content of iron. Positive correlations between some interior design indicators is found. The analysis of lifetime productivity during our research found that high milk yielding cows had highest yields on the first lactation and kept the same level in the next lactations with insignificant variations. The lower productivity animals reached maximal yields on the third lactation with the followed downward trend. Differences between groups in lifetime productivity during research amounted to 16 992 kg. The significant superiority of the heifers with high grown intensity above equal age animals for the duration of feed and water eating, physiological functions and lying. The analysis of variation coefficient is confirmed the observed regularities.
In the article, we have revealed the efficiency of foliar sulfur (potassium sulfate 250, 500, 1000 and 2000 g/ha), molybdenum (celik molybdenum 125, 250, 500 and 1000 ml/ha) and boron (solubor DF 0,5, 1,0, 2,0 and 4,0 kg/ha) fertilizers in various doses of soybean growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Krasnodar region in 2012-2014. The Vilan is a soybean variety most common in the Krasnodar region; therefore it was taken as the research object. It was established that 250 g/ha is the most effective dose of sulphur fertilizer. It’s provided a yield increase by 0,13 t/ha and increase collection of protein and oil (52,9 and 21.1 kg/ha, respectively). Soybean yields were increased by the application of molybdenum fertilizer in a dose of 250 ml/ha by 0,10 t/ha with increasing collection of protein 45,8 kg/ha. Boron fertilizer increased sum of beans and seeds. Variant of 0.5 kg/ha provided yield increase of 0.08 t/ha, but it was 0.26 t/ha in dry 2014
The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands
The study was conducted in a stationary multivariate experiment at the experimental station of Kuban State Agrarian University during eighteen years. The technology of growing winter wheat was improved by the optimization of norms of fertilizers and plant protection systems for different levels of soil fertility. Totally there were 48 technologies for growing winter wheat after and grain: corn, sunflower, sugar beet, where studied in the experiment. The best combination of high yield (77.2 t / ha) with high quality grain (nature - 789 g / l, the total vitreousness - 60%, -14.2% protein content, gluten content - 29.0%) was found under intense technology. The grain quality meets the requirements for the 2nd class. Similar productivity (yield - 76.4 t / ha, the total vitreousness - 55% protein content - 13.4% gluten content - 27.2%) was obtained in and when grown for its resource-saving technology also. All kinds of technologies for growing winter wheat studied in the experiment were profitable, but resource-saving technology was the most efficient. Net income per hectare under this technology was 31,745 rubles, and a cost of 1 quintal of grain - 284 rubles
The organic agriculture is an important issue for sustainable development and food quality production. For this reason we analyzed the data on land use in organic production and the volume of the market for organic products in Europe and Russia. The motivation of farmers and the driving factors for the transition to organic farming methods in developed countries and the role of subsidies have been shown. The analysis of the state of organic production in Germany has been carried out. In 2013, Germany reported 23484 organic farms, which represent 8.2% of agricultural production and the total cultivated area 1,045 Mio. ha. In organic production are involved 9 national associations with their own logos, integrated by 12250 farms (52.2%), and the remaining 11 234 biofarms (47.8%) use the EU-bio logo. Over the past years there has been observed a significant increase in organic livestock production; e.g. during 2007-2012 milk, poultry meat and eggs production were increased by 58.3, 60,6 and 108.7% respectively. Price of bio eggs in November 2014 was 55.6% higher than in free-range system and 100% higher than in floor housing system. Obviously, organic production is an efficient production system capable of ensuring the economic well-being of rural areas. For further expansion of this sector in Russia is necessary to develop the economic incentives, which encourage conversion from conventional, farming to organic production. Also, it is necessary to raise awareness of producers and consumers about the quality of organic products
The article shows prospects of the use of growth regulators on the nature of humic culture of rice in the first place due to the low field germination of seeds, rice crops lodging. Effect of humate on the growth, development and photosynthetic activity of plants, as well as the consumption of nitrogen, phosphorus and potassium results in increased grain yield of rice. Depending on the type of humate yield increased by 5,0-6,4 с/ha. Seed treatment caused a change humates biochemical and technological indicators of the quality of grain. Beans with these options contain more than in the control of protein per 0,13-0,44 % starch - 0,36-1,2 %, decreased membranous grain by 0,2 % and 1 % fracture, raised on vitreousness 1,46-2,0% and the yield of cereals on 1,06-2,0 %
The article presents the author’s insight into the theoretical foundations of plant breeding for self-pollinators and cross-pollinators. From the author’s point of view, plant breeding techniques depend on a type of pollination, population propagation and isolation from other variety pollen. Adaptive properties of crops are described as ones depending on a genetic type (genetically pure lines, populations, hybrids, pure varieties and clones). The key role of seeds in preserving a plant variety, or a cultivar, is emphasized. In the article, cultivar and yield qualities of seeds are characterized. The reasons for seed deterioration and yield decrease have been looked into. Improvement of main crops such as wheat, barley, rye, rice, soybeans, maize, triticale, sunflowers, potatoes, sugar beets is characterized in detail. The author shares the traditional point of view on the seed breeding program. It includes following steps: development phase (breeder’s seed), maintenance phase (in which a quantity of seed is maintained under high standards) and the distribution phase (production of commercial seed for distribution to the public). The difference between primary and secondary seed selection is explained. The best periods for crop rotation and crop renovation are also described. The legally enforceable standards of quality and genetic purity for different crops are presented in the article. It is pointed out that it is vital to maintain high cultivar qualities after multiplication and distribution of the new variety. Only large-scale pedigree system for seed production promotes it
The article presents an analysis of the statistical data on use of barley in the world agriculture. The dynamics of changes in acreage under crop has been studied over the past decade in the global community. The structure of indicators in barley’s area was reduced and the main regions of production have been described. As the world as some countries barley productivity was studied. The article presents the data on world production of barley for lust four years. The structure of production of the main producing counties for 2014 is presented graphically. On the basis of the material revealed, more than half of the total harvest of barley in the world has been produced by three regions: The European Union, the Russian Federation and Canada. The article presents a comparative analysis in the above productivity of barley by the world leaders in the production of this crop. A direct influence of environmental factors on final grain yield has noted. Also the issue of national economic importance of culture has been revealed. We have noted the areas of the culture use such as food, brewing industry, as well as livestock (as it is known, barley is one of the most valuable forage crops)
The article presents an overview and in-depth analysis in the area of barley grain production. The statistical data and comparative analysis of total yield of barley in the Russian Federation with respect to other cultures, widely cultivated in our country, such as sunflowers, oats and wheat has been presented. The structure of sown areas occupied by the culture of barley in the Russian Federation for the period from 1990 to 2013 has been presented graphically; we have analyzed the trend of their increases and decreases over the years. The article presents and visually shows a comparative analysis of crops like winter and spring barley. At the same time, due to a significant warming, distinct advantages of winter crops to spring crops in the cultivation of them in the southern regions of the country have been noted. The recommendations on the feasibility of increasing the cultivated area were made. Indicated by the national economic significance of culture, we show the examples of its use in industrial processing. In addition, long-term analysis of statistical data on the yield of major crops grown in the Russian Federation, such as wheat, barley, maize, millet, oats, rice, legumes, sunflower, soybean has been performed
The article reveals issues concerning the experiments on application of complex water-soluble fertilizer and straw mulching of row-spacing in sweet corn hybrid named Krasnodarskiy 280 CV growing management and the yield of milky ripeness. We have discovered that straw mulching in combination with complex water-soluble fertilizer named Vermisol used in 5-6 leaves, reduced evaporation and tended to moisture accumulation in soil what increased yield of ears for 0,6-1,7 t/ha. The lowest water-absorbing capacity in root-inhabited layer of soil (0-0,6 m) were 28,5 % from dry weight of soil in years of experiment. Registration of sum of precipitations in critical for corn period (in third decade of June and first decade of July) was in tolerable level. The best conditions of precipitation were in 2013, when in June and July the sum was 143 mm, and humidity of the air was in optimum level – 70 %. The temperature of the soil in 0-0,1 m layer in the day of mulching was the same as in the layer 0-0,05 m, tin increase for 5 0C in variants without mulching. The lower amplitude of temperature of the soil in vegetation period since the phase of 10-11 leaves had good influence for yield of milk maturity ears
