ON CRITERIA OF BREEDING OF NEW VARIETIES OF BASSIA PROSTRATA

Posted in 2018, AGRICULTURE, Issue №10(76) October 2018 | 0 comments

The selection of arid fodder plants based on ecological, evolutionary and adaptive principles is one of the topical problems of feed production in the state. The lack of the sufficient range of breeding varieties of arid fodder plants reduces the effectiveness of work aimed at increasing the productivity of natural fodder land and makes it difficult to create a seed-growing system. The purpose of the research was to study the structure of the prostrate summer cypress variety of the prostrate summer cypress Jangar by studying some economic and biological properties of its constituent biotypes. Based on the tests carried out, it is concluded that the Jangar variety is a mixture of biotypes that it is not appropriate to divide them since each of the biotypes is a natural complement to each other showing its properties under certain climatic conditions of the year. Thus, at the present stage, one of the main criteria in the selection of prostrate summer cypress for different soils and climatic zones of Kalmykia should be the selection of varieties with a narrower reaction rate adapted to specific ecological niches.

COLD PASTEURIZATION OF FISH PRESERVES USING ELECTRONIC RADIATION

Posted in 2018, AGRICULTURE, Issue №10(76) October 2018 | 0 comments

Radiation technologies for ensuring microbiological safety and increasing the longevity of food products have become widespread worldwide. Various gamma-systems and electronic accelerators complying with the international standards and safety requirements have been created and are being used. In the Russian Federation, the Radiation Processing Centers are developing energetically by electronic accelerators providing the irradiation parameters acceptable for food products. Work is underway to determine the best mode for radiation treatment of various types of products. The use of electronic accelerators for cold pasteurization of fish products (fish preserves) is very promising – it is distinguished by a high level of microbiological contamination which predetermines the danger to human health and short terms of safe storage. There is a need to evaluate the applicability of various electronic accelerators and possible modes of radiation treatment to achieve the necessary antibacterial effect and preserve sensitive sensory characteristics of irradiated products. To solve this problem, the antimicrobial efficacy of radiation treatment on various electronic accelerators was evaluated (Y003 “Electronics,” ILU-10, UELR-10-10-40, and UELR-10-15-C-60-1) with electron energy of 5 up to 10 MeV of fish preserves samples immediately after the exposure and during storage at low positive temperatures (5±3 °C). As a result of the studies carried out for cold pasteurization of fish preserves, it is recommended to use electronic accelerators of all types considered and irradiation doses from 3 to 6 kGy. There is a need to limit the electron flux density for 10 MeV installations, which requires further study.

FIELD (HORIZONTAL) RESISTANCE OF POTATO VARIETIES TO BUCK EYE ROT IN CONDITIONS OF SAKHALIN

Posted in 2018, AGRICULTURE, Issue №9(75) September 2018 | 0 comments

The results of potato varieties evaluation of different maturing groups according to the field (horizontal) resistance to buck eye rot are presented in the article. It was found that most of the potato varieties studied have a low level of field resistance to the Sakhalin population of the Ph. infestans fungus. The degree of resistance of the vegetative mass to the disease had a significant effect on tuber damage. The greatest yield losses (more than 50%) were recorded under the conditions of severe disease development in unstable high and low-early varieties. The obtained results show that cultivation of unstable varieties in the conditions of the region requires mandatory protective measures. Based on the results of the integrated evaluation, varieties with an average (Gloria, Ketsky) and high (Aurora, Ocharovaniye) level of resistance to the disease were identified.

MATHEMATICAL MODELING AND ASSESSMENT OF CHEMICAL STATE OF SOIL MEDIUM BASED ON DATA OF EARTH REMOTE SENSING

Posted in 2018, AGRICULTURE, Issue №9(75) September 2018 | 0 comments

The paper presents a new approach to the problem of assessing the parameters of the chemical state of soils based on remote sensing data (Earth remote sensing) and ground measurements. This problem remains unsolved, despite high demand for such information in precision agriculture systems (PAS) and modern monitoring systems of the state of agricultural lands used by agrochemical services and agribusiness management bodies. The purpose of this work is the creation of scientific and methodological foundations, software and hardware tools for assessing the parameters of the chemical state of the soil implying the content of basic nutrients in the soil and its moisture reserves. A new approach to assessment was proposed to achieve this goal; it is based on the integration of information from ground-based measurements and remote sensing data. An important feature of the proposed approach runs as follows: a “seed-soil” system is considered as an object of study influenced by the climatic factors. A new simulation complex was created for such an object including multidimensional dynamic models of the parameters of the state of sowing and the soil environment supplemented by models of optical measurements of remote sensing. The complex of such models is the main base for constructing an algorithm of the chemical parameters of the soil state assessment. Such an algorithm is a sequence of stages where the parameters of the mass and chemical state of the sowing are first assessed; the parameters of the chemical state of the soil are later assessed on their basis. In this case, a linearized Kalman filter is used as an algorithm for assessing parameters of the mass and chemical state of the crop. Information is aggregated from terrestrial measurements and data (PAS) in this filter. Due to the inaccessibility of the chemical state of the soil for PA systems, the proposed assessment procedure is closed through the parameters of the reflection of the chemical state of the crop. The criterion for the standard deviation of estimates of these parameters from real PAS data was introduced into the algorithm. General convergence of the algorithm according to this criterion is provided by the adaptation of all mathematical models to real data, formed due to a periodic sampling of the biomass of sowing and soil from the test sites allocated on the main field, the number of which is 12-15, and the area of each comprises 25-50 m2. The availability of information on the parameters of the soil chemical state throughout the growing season will allow making management decisions on the nutrition and irrigation of crops.

HERD REPRODUCTION IS THE MOST IMPORTANT FACTOR FOR IMPROVING THE PRODUCTIVITY AND COMPETITIVENESS OF MILK PRODUCTION IN SAKHALIN REGION

Posted in 2018, AGRICULTURE, Issue №9(75) September 2018 | 0 comments

Providing the population of the Sakhalin region with quality dairy products in affordable quantities is the main task of dairy cattle breeding. To increase the productivity of cows, it is necessary to increase their fertility and the duration of productive use. To a large extent, gynecological diseases of cows hinder the growth of herd reproduction and profitability of cattle breeding in General. The most common infertility occurs in highly productive cows. Breeding work with breeding animals of the region allowed to obtain high milk productivity of cows and stable growth of live weight of young animals from year to year. Animals characterized by high productivity, adapted to the natural and climatic conditions of the Sakhalin region are created. As a result of application of the new principle of selection the genealogical structure of herd in breeding reproducers is formed.

VARIABILITY OF LAMINA MORPHOLOGY IN SEEDS REPRODUCTION OF ALMOND-LEAVED WILLOW

Posted in 2018, AGRICULTURE, Issue №9(75) September 2018 | 0 comments

The article outlines the history of the development of views on the possibility of apomixis in species with different levels of ploidy and the current state of the problem. The problems of cytogenetics of almond-leaved willow (Salix triandra L.) are analyzed. The aim of the research is formulated: To justify the possibility of reduced gametophytic apomixis in seed reproduction of an almond-leaved willow and to reveal the patterns of morphological splitting in lamina during apomictic reproduction of this species. The main methods of plant morphology were used to obtain and process the material: Experimental, descriptive and comparative. We identified a splitting by the morphology of lamina in the seed progeny of a short-leaved form of an almond-leaved willow obtained under the conditions of pollen absence. Along with the typical form (f. typica), we identified seedlings with a unique morphology of leaves: Narrow-leaved (f. angustifolia) and short-leaved (f. brevifolia). The hypothesis about the possibility of gametophytic apomixis of an almond-leaved willow in the form of reduced parthenogenesis with preservation of haploid embryos and spontaneous somatic diploidization in postembryonic stages of ontogenesis is substantiated. The hypothesis of the polyploid origin of an almond-leaved willow was confirmed. Obtained results are recommended to be used when describing the form diversity of an almond-leaved willow in natural populations, as well as when planning the selection process and evaluating the material obtained.
