EFFICIENCY OF SELECTION ON HIGH TILLERING AT VARIOUS DENSITY OF PLANTING OF RICE PLANTS
06.00.00 Agricultural sciences
DescriptionIn 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

DescriptionThe article reveals issues concerning three years research about the rate of influence complex water soluble fertilizers in seed treatment and treatment vegetative plant in phase 3-5 and 7-8 leaves for grain yield increase. In the process of research were determined summarized water consumption and coefficient of water consumption, measuring of morphological signs, were given economical estimation of using complex water soluble fertilizers in corn grain yield increase. The research shows the efficiency of seed treatment of average corn hybrid Krasnodarskiy 377 AMV by complex water soluble fertilizer Lignohumate potassium at dose 0,5 l/t. Grain yield increase in mentioned variant was 4,4 c/ha in comparison with variant of distilled water treatment. The same grain yield increase was got by using in seed treatment the mixture of Albit, 0,05 l/t with Lignohumate potassium, 0,5 l/t. the treatment of vegetative plants in phase 3-5 leaves when were sowed non treated seed were less efficient than in phase 7-8 leaves, where grain yield increase was 4,5 c/ha. Seed treatment of Lignohumate potassium in combination with vegetative plants treatment in phase 7-8 leaves by using Megamix, Bionekskemi and Lignohumate potassium allowed to get grain yield level 80,3-80,8 c/ha

DescriptionThe article presents the results of studying the peculiarities of growth and fruiting of trees of sweet cherry with varying density. It is established that the average yield for the years of fruiting does not depend on tree planting schemes, and higher profitability of production is marked with the scheme of 5,0×3,0 5,0×2,5 m

DescriptionThis article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group

DescriptionThis article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles

DescriptionThis article presents the results of the use of feed concentrate from vegetable raw materials called "Sarepta" in the amount of 5, 7.5% and 10% by weight of the feed, instead of sunflower meal in the feeding of Russian sturgeons. Studies have been conducted among 3 year old Russian sturgeons in the conditions of PRIBOY company in the Bykovsky district of the Volgograd region. The experiment lasted 24 weeks. Replacing sunflower meal with a product of processing of oilseeds - feed concentrate Sarepta, made from vegetable raw materials, in the composition of feed for sturgeons had a positive effect on live weight, absolute, average daily and relative gains and costs of feed. The use of "Sarepta" feed concentrate, made from vegetable raw materials in the feeding of Russian sturgeon contributes to the increase of live weight of 3.1-6.0 per cent, an absolute increase of live weight by 5.07-9.82 percent, and average daily and relative body weight increase. It was also found, that we had a decrease in feed consumption during the period of experience in the experimental groups. Morphological and biochemical parameters in experimental fish in all groups were within the physiological norm, which indicates a normally occurring redox processes in the body
