Apple scab is a widespread disease in the Republic of Artsakh. In order to efficiently struggle against this disease it is necessary to study the virus development related to the climatic conditions. Upon the studies carried out in 2011-2014 it has been disclosed that in conditions of pre-mountainous zone of the Artsakh Republic the critical period for the apple scab development is May-June, that is the end of the apple tree blossoming and the start of fructification period and it is necessary to suppress the virus development through the fungicidal preparations to be applied for that period.

The dynamics of detoxification of a number of pesticides in cucumber and tomato was studied. The preparations were mixed in the water solution of biohumus. In the control variant ordinary water served as the experimental fluid. Studies have shown that when the water solution of biohumus serves as a working fluid, the process of detoxification of cypermethrin and topaz is accelerated in tomato, and that of actellic in cucumber.

In the current work the existence of chloral-organic pesticides - heptachlor and DDTin waters of the rivers Vorotan and Voghji was disclosed through Gas Chromatographic method. It was identified that their concentration was higher than the accepted standards. Prohibited and obsolete pesticides remain beyond control in "burials" that is common in many regions of Armenia. Surveys show that some of these pesticides are also common among population. It is recommended to collect these quantities and keep them under control until the storage facility is completed.

The results of chemical analysis of the seven foreign varieties of Malus domestica against those of two standard ones have indicated that Idared and then Melrose, Goldspur, Maxspur and Starkrimson varieties are relevant for regionalization in the Republic ofArmenia. The data of palynological investigations of Malus domestica varieties will serve as a good basis for further research, in particular, for determination of the origin of domestic apple and the participation of various wild varieties of the genus Malus Mill. in the establishment of this genesis.

The forest brown soils of the Artsakh Republic are often distinguished by the less favorable agro-physical and agro-chemical properties, including low fertility. It is possible to reclaim these soils by means of appropriate fertilizers. According to our observations the processed dacite tuff (PDT) is among these fertilizers, which is fabricated out of the potassium-rich dacite tuffs through thermochemical method. According to the experimental data, in case of applying PDTor“MM”bio-fertilizer in N P K fertilization system the soil water absorption capacity has increased by 5.7%- 15.5 %, water permeability by 16.2%-20.6%and the absorption capacity forNH ion by 14.9%-16.3 % as compared to the same properties of N P K (KCI) variant. The content of mobile nitrogen, phosphorus and potassium has also increased in the soil which is not observed in case of gypsum application.

The results of the field experiments concerning the impact of organomix organic fertilizer and bio-liquid growth stimulator on the growth, development, intensity of tuber accumulation, yield capacity and marketability of the potato cultivated in the irrigated brown semi-desert soils of the Masis province at Ararat region, RA, are introduced in the article. Upon the two-year (2017-2018) investigations it has been disclosed that the fractional application (with sowing and through nutrition) of the same organomix dosage (10 t/ha) has had a more favorable effect on the yield amount (12.9%) of potato and its structural elements than the simultaneous (with sowing) application or through the combination of mineral fertilizers (N P K +N ). Meanwhile, by applying the growth stimulating bio-liquid with the dosage of 14 l/ha (by means of moistening the planting material) before the potato planting the potato yield amount and the tubers marketability have considerably increased (20.5 %) during the vegetation period in comparison to those in case of the top/foliar nutrition introduced with the same dosage.

Drought is one of the most serious problems for agriculture. The aim of this study is to explore tolerant wheat genotypes under drought conditions. One of the practical methods for identification of tolerant wheat genotype is the use of Poly Ethylene Glycol (PEG 6000) .In this research four genotypes (D92, C80,AIOI5,F46) are introduced and four water stress treatments (0 MPa,- 0.5MPa,-0.75 MPa, and -1.0 MPa.) have been carried out for creating drought conditions. Results have indicated that genotypes drought stress levels and their interactions have enormous effects on seed germination, shoot length, root percentage and their fresh and dry weight. Out of the tested genotypes F46 and AIOI5 proved to be drought stress tolerant. However, D92 was sensitive to water stress at germination stage while C80 demonstrated average indices.

The aim of this study was to conduct dietary exposure assessment of tetracycline residues through consumption of cultured Ishkan fish meat in Armenia. Tetracycline concentrations were detected by enzyme linked immunosorbent assay method (ELISA). The results indicated that the contents of tetracycline residues exceed the maximum allowable concentration (MAC) value in more than half of the samples. However, due to relatively low consumption of Ishkhan fish, the Hazard Quotient (HQ) is less than 1, indicating a low health risk.

Poultry farmstead provides citizens with fresh eggs and meat, as well as funds family budget at the expense of income from the sale of poultry products. However, violation of veterinary and sanitary rules and unsatisfactory maintenance and feeding conditions contribute to the emergence of infectious mycoplasmosis, leading to a decrease in productivity, and often, to the birds diseases. The aim of our work is to conduct complex epizootiological, clinical, pathological and bacteriological studies in private poultry farms of the community Jrashen atYerevan city. To prevent further development of respiratory mycoplasmosis by farmers, we have proposed a comprehensive plan for veterinary and sanitary measures.

Taking into consideration the fact that very often producers decrease the cost of products through adulterations, particularly through the replacement of animal protein with plant ingredients, a study has been carried out, which is aimed at the detection and evaluation of adulterations observed in the market of sausage products. In all samples of sausage products studied in 2017, and in the majority of sausage products studied in 2018 soy protein allergen was determined, however, the relevant labeling was missing. The latter is not only a legislative, but also a public health issue.

In this article justifications of using underground water for irrigation purposes of lands in the landscape ofArmavir region are introduced: water intake has been implemented from low pressurized aquifer by repairing existing boreholes and by drilling new ones. Research on hydrogeological conditions of the selected area, its analysis and schematization has been performed. Hydrogeological calculations of boreholes with actual discharges are presented as an example, taking into account the permissible drop rate of piezometric level. As a result, the groundwater level drawdown of an aquifer has been obtained under possible discharges, considering the hydraulic connections between the aquifers. The obtained results will enable to regulate working regimes of both new drilled and already operating boreholes in the region, as well as those under construction.
