Published: December 2019

Natural Rubber (Hevea brasiliensis Muell Arg.) is one of the important plantation commodities in Indonesia. As source of employment, this commodity provides a significant contribution as one of non-oil and gas foreign exchange sources, supplies for rubber raw material and plays a vital role in encouraging the growth of new economic centers in the rubber plantation areas. Indonesia has the largest rubber plantation area in the world but its productivity is still lower than Thailand. The productivity of rubber in Indonesia has not been maximized due to most of rubber plants (85%) are managed by smallholder plantations with low of productivity. The efforts to increase the productivity of rubber plants in Indonesia are the right steps to take. To increase rubber production, proper management and cultivation are needed. The use of stimulants is an alternative way to increase the production of rubber and it benefits in reducing lead costs caused by higher labor costs. Research on the Application of Concentration and Technique of Giving Polyetilene Glycol Stimulants to Rubber Crop Production PB 260 clones shows that the application technique and the concentration of PEG stimulant significantly affected the latex volume, latex weight and Pre-processed Rubber (bokar) weight, but did not significantly affected on dry rubber. The application technique and 2% of PEG stimulant with the bark application (BA) technique on PB 260 clones gave the best results on the parameters of latek volume (61.28 ml), latek weight (57.60 gr), and Pre-processed Rubber (bokar) weight (57.90 gr). It is considered as the best treatment. It is recommended to apply topical system tapping technique (Bark Application) with concentration of 2.5% PEG stimulant in rubber plants PB 260 clone.

Published: December 2019

The presence of carbohydrates, especially glucomannan, causes porang tuber to be important in some industries including food, cosmetics, medicines, and other industries. Porang has four growing periods (GP) in its life cycle. The GP1 until GP3 is the vegetative phase and GP4 is the generative phase. The tubers used as industrial materials generally were derived from GP2 and GP3 plants. The study aimed to analyse carbohydrate components in porang tubers from GP2 and GP3 plants using Liquid Chromatography Mass Spectrometry (LC-MS) method. The tubers produced from plants at GP2 and GP3 were extracted by maceration method using methanol solvent (pa) for 1 h. Liquid extracts obtained was further identified for the levels of carbohydrate components using LC-MS technique. The carbohydrate components identified with LC-MS were selected for quantifications. LC-MS analysis showed that both GP2 and GP3 tubers contained 67 types of chemical compounds. In the GP2 tubers 8 types of carbohydrate components were detected. Whereas in the GP3 tuber in addition to the 8 types of carbohydrate components that are the same as ini the GP2 tuber there is also 1 other type of component, namely trehalose. Glucomannan is the highest levels of the carbohydrate component in GP2 and GP3. However, glucomannan levels in GP2 tuber (58, 845.54µg/g) were lower than those in GP3 tuber (99, 436.85µg/g). Therefore, GP3 tubers are better than GP2 to be used as industrial materials.

The use of resistant varieties is the most economical and safest method of disease control. Knowledge of the resistance genes of the host plant greatly facilitates their effective use in breeding. The gene postulation method helps to quickly identify probable rust resistance genes (Lr genes) presented in a large number of wheat varieties at the same time. The aim of this work is to test the genes of juvenile resistance to brown rust, potentially present in 11 varieties of winter soft wheat sown in southern Russia, using ten isolates P. triticina. To identify resistance genes, types of damage (TD) by 10 fungus isolates on 11 varieties were compared with TD on a standard set of almost isogenic lines of Tatcher. If the stable reaction on the line and variety coincides with the majority of fungal isolates with different virulence, the corresponding gene of resistance of the line and variety is also matched. The resistance of varieties and lines to the pathogen in the phase of adult plants was evaluated in the experimental fields of the All-Russian Scientific Research Institute of Biological Plant Protection in 2017. Lr genes were postulated in ten varieties in juvenile stage: 2a, 3bg, B, 18, 20, 21, 25, 28, 29, 30, 32, 43, 45, 47. In the adult state of plants, Lr29, Lr32, Lr43, Lr45, Lr47 genes are effective to the North Caucasian population P. triticina. Varieties in which effective genes of resistance to brown rust have been postulated are recommended for further use in breeding and territorial distribution in southern Russia.

Assessment of the effectiveness of treatment and recovery of reproductive functions of cows with fatty liver decease using a drug based on a healthy liver hydrolysate (the enzyme structures of the protein after acid treatment and centrifugation remain in the sediment of the tissue substrate, and their released amino acids become constituent components of the over-sediment solution of the hydrolysate). Two groups of animals of 15 heads each were formed: first-calf heifers entered the first group on the first day after calving, liver pathology was indicated by an increase in its borders during percussion, and animals with clinical signs of deep fatty liver disease were included in the second group a month after calving. The dose was 40 ml daily (20 ml intramuscularly and 20 ml subcutaneously), the course of treatment was 5 days. After the 1st stage, the remaining 25 cows of both groups were considered as one experimental group of the 2nd stage, which was periodically monitored until the next calving and insemination; the control was 25 animals not subjected to hepatoprotective therapy. Cows that underwent even one treatment procedure were better adapted to the newborn period and subsequent insemination. They have faster involution of the uterus and the resumption of the sexual cycle (P <0.001), higher fertility, and a greater number of healthy calves.

The paper contains a description of the method, which allows assessing soil suitability for growing improved seed potatoes by the totality of microbiological characteristics of the soil. An indicator of the level of suppression of the soil microbial community is proposed as the main indicator of soil suitability, which is based on the species diversity of the soil microorganisms and its total suppressive activity against potato pathogens, in particular Fusarium solani. Among the six soil sites tested by this method at one of potato farms in Tomsk Region, virgin land sites, a site that had been in a fallow state for a long time, and an arable site that had been fertilized for several years were recognized as the most suitable for growing improved seed potatoes.

This paper presents the results of experimental studies of the effect of feeding different doses of thyme extract on the morphological and immunological blood parameters of broiler-chicks. The medicinal plant extract of thyme (Thymusserpyllum L.) was obtained in the research laboratory “Agroecology” of Kemerovo State Agricultural Institute by water-ethanol extraction with subsequent low-temperature vacuum drying. The research works were executed in conditions of industrial poultry farm for broiler-chicks of HubbardISAF 15 cross, experiment duration - 40 days. According to the principle of similar groups, 1 control and 5 test groups of one day old chicks were formed, 37 in each group. Birds of all groups received full all-in-one feed, and test groups received additional thyme extract in doses of 2, 4, 6, 8, and 10 mg/kg of body weight. For laboratory studies, blood tests were taken from 6 chicks (3 cockerels and 3 hens) from each group on the 1st-day of life by decapitation method, and then on the 21st and 40th-day of research - from the wing vein. It was determined that the introduction of thyme extract into the diet of broiler chicks in the above doses led by the end of the experiment, with varying degree of accuracy, to an increase in the number of erythrocytes and hemoglobin in the blood, which indicates stimulation processes of erythro-and hematopoiesis. Decrease in the phagocytic number, phagocytic index and lysozyme activity of blood serum, by the end of the experiment, indicate a decline in the antigenic impact on the immune system of the tested birds.

The paper discusses the formation of national competitiveness, including its determinants. The role of an integrated business risk insurance system for a competitive national economy, as well as public-private partnerships for the harmonious development of venture financing, is substantiated. A hedging financial instrument is seen as a means of mitigating the risks of venture capitalists and project developers. An analysis of the degree of risk is proposed as a necessary step prior to the decision to hedge. The stage of fixing the market follows the adoption of such a decision. Correlation-regression analysis allows establishing how indicators of price dynamics for the spot instrument and the corresponding futures are interrelated. The probabilistic nature of the variant development of investment and innovation projects in the course of economic activity of market entities should be taken into account when assessing the risk caused by material, labor, financial and other losses. Financial guarantees are subject to compulsory insurance in case of risks associated with transactions with financial assets.

The aim of the research was to study the correction of ossification processes and the mechanisms of humoral regulation of this process in the pathology of vitamin-mineral metabolism against the background of an immunosuppressive state in piglets. As a result of the experiment, it was found that proposed pharmacological correction scheme contributes to an increase in the level of total calcium (3.48 ± 0.29 mmol/l), ionized calcium (1.65 ± 0.07 mmol/l), ion-exchange calcium (2.52 ± 0.05 mmol/l), and protein-bound calcium (0.54 ± 0.06 mmol/l), 2, 3-diphosphoglycerate (1.43 ± 0.02 mmol/l), vitamin A (2.63 ± 0.09 μg/l), citric acid (2.90 ± 0.16 μg/l), a significant decrease in alkaline phosphatase activity (2.02 ± 0.04 mmol/l). Optimization of the structural and functional organization of the thyroid and parathyroid glands was noted, activation of hematopoiesis and bone tissue remodeling was observed in bone tissue, which suggests a pronounced reparative and osteoprotective effect of the proposed pharmacocorrection scheme.

Published: December 2019

A decrease in the technical potential of the agro-industrial complex of the regions and Russia due to a decrease in the availability of equipment and significant aging is shown, which imposes special requirements for ensuring its performance due to a well-organized technical service. It is possible to maintain high availability of machinery through the regional system for ensuring the operability of agricultural machinery. The aim of the study is to develop a method for ensuring the operability and availability of equipment for its effective use based on the use of service technical clusters. The system for ensuring the operability of agricultural machinery provides various options for servicing consumers from the following levels: economy, district and region. A normative and calculation method is proposed for determining the parameters of the regional system for ensuring the operability of agricultural machinery in order to reduce labor intensity, according to which its parameters are calculated for model technical service clusters: economy and district. The obtained parameters for model levels of the economy and the district are adjusted taking into account the main actual indicators for the zone served by this level of the system. The proposed regulatory calculation method for determining the parameters of the system for ensuring the operability of agricultural machinery was implemented for the Novosibirsk region. Based on a certain laboriousness of the equipment being serviced, a regional model service cluster and a model service cluster of a farm (a farm with average indicators for the region) are substantiated. The conversion factors from model service clusters to actual enterprises at the district and farm levels are given.

Published: December 2019

The paper is devoted to studying the motion dynamics of stem and ear, as well as particular wheat grains. The purpose of this consideration is to establish parameters of the effect on the plant as a whole, and in particular on the ear, for the efficient extraction of grains from the ear. For this, a mathematical model of the interaction between the elements of the stem-ear-grain system and the conditions for the separation of grain from the ear is built. In a first approximation, a simple stem model consisting of absolutely rigid bodies interconnected by elastic bonds is taken as such a model. Stems with a given moment of inertia act as such bodies, and spiral springs act as elastic bonds.
