INFLUENCE OF ENRICHMENT SEEDS WITH COPPER ON RICE YIELD

abstract 1321708023 issue 132 pp. 288 – 305 31.10.2017 ru 434
We have studied the effect of presowing enrichment with copper on the seed yield of rice. We have found optimum concentration of water solution of copper, which provides higher yields of seeds and evaluated the impact of the enrichment with copper on the growth processes in the plants of rice. The studies were conducted in elite seed-growing enterprise "Krasnoe" of All-Russian Research Institute of rice. It was found that for rice-growing farms of the Kuban region with the aim of increasing the quantity and quality of grain yield it is necessary to make sowing of rice seeds enriched with copper. This application should be carried out by wetting the rice seeds with 0,5 % water solution of the microelement with a semi-dry method, i.e. the rate of 10 liter working solution of copper in 1 ton of seed. The article proves the economic feasibility of enrichment of rice seeds with copper

INFLUENCE OF FEEDING AND LIVESTOCK MANAGEMENT ON DEVELOPMENT OF HOLSTEIN CATTLE GENETIC POTENTIAL

abstract 1051501017 issue 105 pp. 325 – 338 30.01.2015 ru 941
This research reviews an analysis of several problems of milk production process as well as fast methods of dairy cows' health control widely used in the countries of high-level dairy breeding. The results of milk analysis via test stripes reveal that about 30% of cows during transition period - phases transit 2 and 1st phase of lactation - have clinical and subclinical ketosis marks what comes as one of the reasons of cow's low productivity. Evaluation of cows' fatness evidence that only 46,4% of tested animals have normal fatness according to the appropriate lactation period, whereas other animals have too high fatness index and only very small part - 1% have extremely low fatness index. Cows' obesity leads in future to ketosis and disturbance in metabolism. The research also revealed nonconformities in boxes size, they do not satisfy requirements of comfortable Holstein cows handling. The article provides recommendations on implementation of tested methods based on survey in order to suggest the ways of milk production efficiency increase

INFLUENCE OF FERTIGATION, DRIP IRRIGATION AND FOLIAR NUTRITION ON PRODUCTIVITY OF APPLE TREES, FRUIT QUALITY AND SOIL PROPERTIES IN INTENSIVE ORCHARD OF THE CENTRAL CHERNOZEM REGION

abstract 1301706070 issue 130 pp. 958 – 974 30.06.2017 ru 271
The trials were conducted in 2013-2015. Research objects: apple trees cv. Zhigulevskoye/62-396, year of planting – 2007, at 4,5x1m. Place of research – experimental orchard of ”I.V. Michurin Federal scientific centre " in Tambov region. The goal of research: to study the effect of fertigation and foliar nutrition in an intensive apple orchard. During the research there were done yield records, was determined the content of nutrients in leaves and soil. In the soil there was also determined humus content and acidity, fruits were analyzed on vitamin C, saccharides and organic acids contents. Nitrogen in leaves and soil was determined by Kjeldahl method, phosphorus by photocalorimeter KFK-3, potassium and calcium by flame photometer Jenway PFP-7. We have established the optimal average application rate for fertigation in conditions of the Central Chernozem zone of Russia, which could be used to calculate specific application rates with data of soil-leaf diagnostics. In our research, it is shown that the use of this application rate had no significant negative impact on the studied parameters of soil. It is shown that the biochemical composition of fruits is largely determined by weather conditions of the year of vegetation and foliar nutrition. Maximum efficiency of measures for mineral supply optimizing is achieved only with the good combination of fertigation and foliar nutrition

INFLUENCE OF FOLIAR NUTRITION ON CROP AND QUALITY OF APPLES

abstract 0460902001 issue 46 pp. 1 – 7 27.02.2009 ru 3673
The article shows the results of the impact of foliar nutrition on crop and product quality of the Grenny Smith apples. Also the impact of the agricultural practices to fruits saving ability is discussed, as well as their quality in terms of sugars, acids and vitamin C. It was found that the use of 3-fold foliar nutrition feeding with nitroammofoska impacts positively on the results of storage.

INFLUENCE OF FRUITLESS SHOOTS ON QUANTATIVE TRAITS OF GRAPES AND WINE OF SAPERAVI VARIETY

abstract 1081504038 issue 108 pp. 512 – 532 30.04.2015 ru 1333
In this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same

INFLUENCE OF GREEN MANURE AND INTERCROPPING CULTURES IN THE CHAIN OF IRRIGATED CROP ROTATION ON PRODUCTIVITY AND QUALITY OF VEGETABLE CROPS

abstract 1111507082 issue 111 pp. 1289 – 1298 30.09.2015 ru 865
The article presents the results for the study of productivity and quality of vegetable crops in irrigated chains of crop rotation by using intermediate and green manure crops. The greatest number of units of grain produced in the first variant of the experiment, where in a part of crop rotation cultivated sweet corn, mustard as a green manure for potato and onion planting summer planting seeds in the ground and reached 37.4 tons of grain units. The infection of potato tubers with complex disease was lowest at the control variant and compose 11 %. The highest infection with diseases of potatoes fixed at the intermediate and without the use of Side-General culture and was 18 %, which is 63.6 % more than the control options. When we are using intermediate crops diseases of onion increased by 7,7–15,4 % in case of green manure using. When you include treatment of the soil under the previous culture it was the largest infest with diseases and was 16–17 %, which is by 23.1 and 30.8 % higher than in the control variant. Based on these results, we can conclude that the use of green manure crops and intermediates more favorable effect both on the productivity of the subsequent crops or the quality and marketability

INFLUENCE OF IMMUNIZATION ON THE DEVELOPMENT OF INTERNAL ORGANS OF YOUNG EGG HENS

abstract 1051501066 issue 105 pp. 1098 – 1121 30.01.2015 ru 1095
Assessment of the nature of the impact of preventive immunization of growing chickens on the results of cultivation and state agencies involved in immune reactivity is the first step in finding ways to eliminate the negative effects of immunization. The results show that the healthy birds posses two sharp peaks of exceeding norms by weight of the liver – aged 50 days and 84 days - more than 20%. Spleen weight at the age of 40 days exceeds 20%, and 50 days shows the greatest deviation from the norm. In the future, the relative weight of the spleen de-creased, and 84 days of age comes into compliance with the norm. The most significant change in the relative weight of the spleen and liver of poultry is set at the age of 50 days. The authors attribute this fact with a forced need to implement an immune response in a specified bodies accumulating overload antigenic incentives
