The article analyzes the peculiarities of different transport modes indicating the advantages of cargo transportation by motor vehicles. It is shown that the transportation of both dangerous and oversized heavy cargo, especially in mountainous areas, requires strict observance of safety rules, especially when about 20 % of the total cargo transportation includes hazardous cargo. It was also noted that there are tools and equipment (cargos) that requires professional rolling stock for transportation, while for some cases special means should be created for transporting the given cargo, including platform, trailer, trolley, etc.

In the result of field experiments on the soil-tiller with self-vibrating (mobile) and fixed blades, the regression equations y=f(X1,X2) of the torque moment dependence (Mt, y) in the soil-tiller’s drum on the drum’s rotation numbers (nd, X1) and soil loosening depth h (X2) have been derived and the set of curves describing the aforementioned dependences have been designed. The results of research experiments have stated that the torque moment is reduced parallel to the increase of rotation numbers in the drums with selfvibrating (mobile) and fixed blades, while it grows up together with the increase of soil loosening depth.

The first article of the series considers the results of theoretical research on the plants stems cutting in dense environment (water, soil). It has been proved that in case of necessary technological speeds in the blades of the rotary cutting apparatus the resistance forces of the environment are much more extensive than the force of the very stem cutting. The double increase in the rotation numbers of the rotor in the cutting apparatus brings about the increase in the resistance forces of the environment in about five times, which makes the use of the cutting apparatus of the mentioned series quite irrelevant from the technical and technological perspective.

Laboratory experiments on the self-driving rotary clod-crusher in the potato digger has been implemented which is aimed at the specification of kinematic and dynamic parameters resulted from the theoretical researches. During the experiments a torque measuring resistance strain gage of TRA-50K series, Zet-210 analog-to-digital converter, appropriate booster (Zet-410) and recording equipment have been used. Three finger types of the recommended clod-crusher have been experimented: cylindrical, cylindrical with hemispheric facade and conical. The experiments indicate that the theoretical research results accurately address the principle of the problem and they can serve as a background for the design and preparation of the clod-crusher.

The aim of this paper is to estimate the main factors affecting per capita pork consumption in Armenia. For this analysis, the log linear model of per capita pork consumption was estimated.

West-Palaearctic wood mice species of the genus Apodemus sensu lato is widespread in Armenia. The current work considers the areal distribution of the wood mice species throughout all regions of the country. These rodents are actively involved in the circulation of zooanthroposes and can be pests for agricultural crops and forest plants. The results are validated upon the applied methods of genetic analyses.

Investigations carried out in 2017-2019 under dry agricultural conditions at the Hrazdan province of the Kotayk region have disclosed that out of the two tested soil cultivation variants (deep ploughing, single disk harrowing), soil loosening with the single disk harrowing is the most efficient variant for the winter wheat cultivated in the black soils, while out of the applied technologies (organomineral fertilizers and zeolite), that of the zeolite, manure and N30 applied on the background of P90K90 is the best variant. When applying this variant the soil agro-meliorative properties improve and 55.0 c/ha grain yield is harvested. Thus the mentioned variant is recommended for the introduction in the agricultural production.

The current studies are related to the efficiency of the seeding rate variants determined for the fine seed lentil variety “Armyanskaya 88”. The experiments were carried out in 2017-2018, in conditions of Tsovak community of the Gegharkunik region. In the dry soils of Vardenis province in the Gegharkunik region, the lentil plant ripens in 88-92 days (the first ten days of August) and can be proper precursor for the winter wheat. Based on the mathematical processing data of the seed yield capacity and the received profit it is recommended to sow the small-seeded lentil with the rate of 2.7 mln viable-seed/ha in the land areas of Vardenis province in the Gegharkunik region and in other zones with similar climatic conditions.

The effect of nitrogen nutrition with different doses and application methods on the quantity and quality of potato yield in the irrigated conditions of the Askeran region of NKR was studied throughout 2018-2019. Four fertilization variants have been studied: manure 25 t/ha+P90 – background (control), background+ N30+(35+35) - pre-sowing and split nutrition, background+N100 - single nutrition, background+N120 - single nutrition. As a result of conducted studies and estimations of economic efficiency, it has been disclosed that among the tested variants the highest gross and commercial yield was provided by the variant of background+ N30+(35+35), which amounted to 321.5 c/ha and 250.5 c/ha respectively. Meanwhile, 2.6 mln AMD profit has been resulted from the sale of marketable product.

Artificial Intelligence (AI) technologies are used in various sectors of the national economy, particularly in agriculture. These technologies are used in various fields of agriculture: detection of plant diseases, classification and identification of weeds, crops identification and computation, water and soil management, weather (climate) forecasting, determination of animal behavior, etc. This paper reviews advanced Artificial Neural Network (ANN) techniques available to hyperspectral data processing, with a special emphasis on plant disease detection. It is proposed to apply the developed ANN model to the agriculture of the Republic of Armenia to make it more modern and efficient.

The aim of the current article is to study the impact of the measures taken via replanting of the radish seedlings and via leaving them in the sown areas (without replanting) on the morphological changes and seed productivity of the radish seed plants. The research results have evidenced that the replanting of the plant seedlings is the best option for the radish seed production. In case of replanting 5.5 % more seedpods with large and uniform seeds have been developed on the floriferous shoots of the seedlings and the seed productivity per plant has exceeded the rivaling variant by 66 %; besides, the average weight of 1000 seeds exeeded the competing variant by 2.5 g.

The garlic varieties “Javakhk” and “Parvana-3” have been bred through the method of clonal selection upon the development of variety populations imported from Javakhk. Their yield capacity has made 114.0 c/ha and 120.0 c/ha, exceeding the control variety “Dzyunik” by 23.9 % and 30.4 % respectively. The produced varieties surpass the control variant also in the bulb preservability, biochemical indices and disease resistance rate, which serves as a background for submitting them to the state variety trial. It is recommended to cultivate the new varieties in the Ararat valley and its submountain areas for getting marketable yield, while it is relevant to grow them in mountainous areas for getting seed grains.

The antibody titer of the blood serum in the experimental animals treated with galarmin d-15 derivative of proline-rich polypeptide combined with inactivated streptococci has been evaluated according to the serological (precipitation) reaction. The investigated blood sera have been diluted in the physiological solution with the ratio of 1:5-1:20. It is worth mentioning that as a result of interaction with the antigen, blood sera, treated with galarmin derivative and inactivated streptococci, have generated precipitate in case of 1:5-1:20 dilution ratio, while in the control variant it has been marked in case of 1:5-1:10 dilution ratio. As a result of numerous experiments it has been found out that the galarmin derivatives are modulators for the activation of humoral and cellular immunities.

This study aims to assess the dietary exposure of trans-fatty (TFA) acids through the consumption of ice-cream in Yerevan. To this end, 24-hour dietary recall method is used to investigate the ice-cream consumption. TFA contents in icecream samples are determined using gas chromatography-mass spectrometry. On the average, people consume 0.018 g/day TFA through ice-cream for the whole year, while 0.111 g/day in summer. TFA intake through ice-cream consumption accounts for 0.007 % and 0.041 % of the total energy intake for a year and for summer season, respectively. Comparing with the WHO’s threshold (less than 1 % of total energy), the daily intake of TFAs via ice-cream consumption during summer warrants some concerns.
