Investigations have been conductd to determine the detoxification rate of Confidor and Pegas in the tomato fruits grown in greenhouse conditions.

The total residual amount of Confidor in tomato fruits was lower than the maximum allowable level 3 days after experimental treatment (0.5 mg/kg). Detoxification of Pegas was rather long-lasting. Thus, to ensure safety, it is required to set up more than 7 days of “waiting period”.

According to investigations application of stimulants after vine cutting preplant treatment through trench ploughing (traditional) method exerts a favorable effect on the growth and development of the rootstocks and aboveground mass of plants. Not only does it intensify the rooting process but also increases the survival rate of the rootstocks.

During the experiments when treating Sev Areni grape variety with zircon, it provided a high survival rate (84 %) compared to control variant, while the application of heteroauxin provided a high survival rate (80 %) in the rootstocks of Voskehat variety. Thus, it is recommended to treat the rootstocks with the mentioned stimulants before planting them in the soil.

The studies have indicated that under the influence of technogenically polluted waters of the river Debed, the humus content in the soils decreased, the mechanical composition turned from heavy loamy into medium loamy and the reaction – from slightly alkaline to neutral and subacidic. The content of gross nutrients and the amount of absorbed cations decreased. The content of gross and mobile forms of heavy metals (HM) increased. The accumulation of HM (Cu, Pb, Mo) in vegetable crops exceeded the maximum allowable limits in many times and posed danger to human and animal health.

Investigations have been conducted to determine the heavy metal pollution rate of the crops grown in the nearby areas of Martuni-Vardenis highway and to identify their distribution in the plant organs. According to the obtained data, in the grains of winter and spring wheat and in the potato tubers cultivated in the adjacent areas of the mentioned highway the copper content exceeded the control sample in 1.13-1.30, 1.06-1.18, 1.07-1.28 times, while the lead content – in 2.20-3.05, 2.94-4.71, 1.51-1.82 times. The maximum heavy metal accumulation has been recorded in the roots

Experimental studies were carried out using in vitro methods to isolate the apical meristems of the Latona and Nevsky potato varieties regionalized in Armenia and to regenerate healthy plants therefrom. Modified methods of growing virus-free plants and producing minitubers in greenhouse conditions and then those of producing healthy potato seed material therefrom have been developed and optimized. It has been justified that the yield and profitability of the in vitro healthy minitubers of the studied potato varieties are much higher than the uncured potato planting material used in Armenia.

An orchard of different bog bilberry varieties has been established for the first time at the Bavra community of Shirak region situated in the horticultural piedmont zone of Armenia. To ensure efficient growth, the planting was carried out through the method of mounding planting of the potted plant root by applying specially prepared organic soil mix. The planting technology has been developed in line with the world research and practice.
The establishment of an orchard with Duke, Legacy winter-hardy varieties is a novelty and can promote the expansion of bog bilberry nurseries, as well as ensure early profitability due to the yield-producing capacity in the second year.

The results of the current study showed that unlike traditionally produced strawberry planting materials, application of those treated per in vitro method has promoted reduction of plants infection level with various diseases (fungi, etc.). Meanwhile, the number of vegetative and generative organs of plants increased, which entailed to the considerable yield capacity increase. At the same time, the fruits’ qualitative indices remained unchanged.

A number of investigations in different regions of Armenia have been conducted to study prevalence and seasonality of leishmaniasis in dogs. The diagnosis was made on the basis of clinical signs observed in dogs, as well as immunochromatographic examination of blood samples taken from animals suspected of being infected with leishmaniasis. The disease was detected in dogs of all age groups.
It is recommended to implement measures to eliminate the sources of leishmaniasis infection and prevent the spread of the disease.

The conducted investigations testify that due to the genotypes and their occurrence frequency in mother turkeys, the numerical sex ratio undergoes certain changes in the generation. Males emerged from the mothers with TfAA CpCD HbAB and TfBD CpCD HbAA genotypes make up about 78 and 69 %, whereas females produced from the mothers with TfAA CpCD HbAB and TfBD CpCD HbAA genotypes are 65 %. The number of males and females produced from the mothers with TfAB CpBD HbCC, TfBC CpAB HbBD and TfCD CpCC HbCD genotypes is equal (P>0,999). The obtained outcomes can be applied in the turkey breeding activities as genetic markers.

The dynamics of the bovine babesiosis prevalence has been studied in conditions of various ecosystems. In spring, summer and autumn animals of different age groups over 6 months old have been investigated. It has turned out that the spread of the disease is particularly promoted by the ticks of Rhipicephalus genus propagated in favorable climatic conditions, which produce up to 4 generations in individual geographic zones of the Tavush region and cause huge economic damages. Thus, the development of scientifically justified complex therapeutic and preventive measures against the disease pathogens and pasture ticks is a priority issue.

Currently, the atrophic rhinitis of pigs is registered in some pig breeding farms of the Armavir and Kotayk regions. According to investigations swines of all breed and sex-age groups are susceptible to the disease but the inherent symptoms are manifested in the 3-5-month-old fattened gilts.
In Armenia the spread of the mentioned disease is promoted by the disposing factors and economic relationships between pig breeding farms. Rehabilitation of insecure pig breeding farms, as well as measures to prevent the further spread of the pathogen, were carried out in accordance with the directive on measures for the prevention and control of diseases. Sulfaprim 48-BT preparation was used for treatment.

The research has been conducted with the aim of developing efficient way for nephritis treatment in dogs. After making diagnosis based on the results of clinical, hematological and blood biochemical indices, as well as those of urine research, the treatment was organized per appropriate patterns. The combined application of cyprinol-500, furosemide, galavit and tavegil with antibacterial, diuretic, immuno-stimulating, antihistamine effect, has ensured high therapeutic efficiency in the treatment of dogs’ nephritis.

The investigations have been conducted in four regions of Armenia to detect the cows diseased with latent mastitis in different livestock farms and to treat them through the new recommended method by using blue iodine. The latent mastitis has been diagnosed by means of Californian test. Out of 127 heads of researched animal latent mastitis was detected in 48 stocks (37.7 %). The animals of control group were treated with Eficur drug and those of experimental group – with blue iodine. Due to the active agents, blue iodine has provided high efficiency speeding up the treatment by 2-3 days.

Development of the technologies for manufacturing new product ranges in chocolate production industry is related to the market demand. An objective has been set to produce dark chocolate rich in food fibers. Wheat bran has been used as a functional ingredient, which contains large amount of valuable substances and dietary fibers. The latter are highly significant for the regular functioning of a human organism.

The purpose of the study is to assess the content of toxic elements (Pb, As, Cd, Hg) in potatoes produced in Armenia, the peculiarities of uptake from the soil, as well as possible health risks associated with the consumption of potatoes by the adult population.
When calculating the transfer factor of toxic elements from soil to potato, rather low values have been recorded (TF<1), which testifies that the potato crops cultivated in different regions aren’t bioaccumulators of researched toxic elements. Besides, the daily intake of the mentioned elements has been estimated and it has been pointed out that the potential risk associated with potato consumption is within the acceptable level.

Development of new food production technologies using high nutrient value raw material is an important prerequisite for the food industry improvement.
The world practice has shown that the best option for balancing food components is the combination of plant- and animal-based food components which enables to stabilize the functional and technological properties of a raw material, increase its biological value and improve the organoleptic properties of the finished product. Thus, it is recommended to apply the new semi-finished production technology in the meat industry upon the supplementation of pearl barley flour.

The chemical composition of wild buckthorn berries (fruit pulp, seed, shell) grown at the Sevan basin has been investigated. Fruit and berry alcoholic beverage has been produced from the buckthorn berries. The physicochemical and organoleptic indices of the produced wine material and fruit and berry alcoholic beverage has been determined.
The beverage produced from the wild buckthorn contains natural bioactive substances, and hence, due to the developed technology the production of high-value fruit and berry alcoholic drinks can be ensured.
