It is recommended to introduce electro-mechanical alarm system with new management methods for the adjustments of working parts in the tillers used for the cultivation of inter- trunk spaces in the perennial plantations. It will enable to apply relatively smaller forces (10-12 N instead of 150 N) for the drive of hydro-system. At the same time the improper mechanical impact on the tree trunk will be rejected enabling to use the machines equipped with the mentioned signaling systems in the orchards of all ages with any anatomical and morphological composition.

In the technology of cottage cheese production the milk fat was completely substituted by milk and vegetable oil emulsion, which had been derived from skimmed milk and olive oil with the ratio of 50:50. The organoleptic, physicochemical and safety indices of the food product have been investigated. The produced cottage cheese can be used in the technology for functional food production due to the large content of useful unsaturated fatty acids, vitamins and antioxidants.

The research has been conducted on “Agroholding” sheep farm, where 860 heads of sheep are bred, 66 % of which are Armenian semi-coarse-wool breed and 34 % are other breeds. Sheep bonitation has been conducted according to their breed, age and productivity characteristics. To improve the qualitative composition of the animal stock, breeding and selection works should be continuously implemented on the mentioned farm. It is recommended to apply such breeding technology which would enable to improve not only the breed’s qualitative composition but also to increase both milk and meat productivity.

Formation of a cluster system in the agricultural sector of Armenia could enable to handle the current obstacles in the food value chain and to increase the economic efficiency in grain production. Implementation of the program on introducing a cluster system for cereal crop production in the Shirak region of the RA implies application of efficient branch management systems and innovative technologies in the farm households, targeted resource utilization, provision of competitive environment, as well as increase in the yield capacity and profitability of the cereal crops.

According to the conducted research it has been found out that the direction and intensity of water and salt regimes in the irrigated land areas of the Ararat valley are related to the ground water levels, mineralization, crops᾿ species composition and to the irrigation factors. Under conditions of high level of ground water (<1.75 m) some salt accumulation is observed in the mid and surface soil strata, which can lead to the decline of soil fertility and crops productivity. Hence, it is recommended to implement irrigation and leaching activities in spring and autumn seasons along the mentioned land areas increasing the irrigation rate in 1.5 times.

The second article of the series considers the theoretical justification of technological innovations for cereal crop seeding. The effect of the seeding ploughshare on the seed grain and soil has been investigated. A new seeding technology in line with agro-technical requirements, structural parameters of the ploughshare, physicotechnological properties of soil and seed has been developed. The recommended technological and structural solutions can serve as a background for conducting respective scientific experiments in future.

In 2018-2020 a new technology against the harmful flora of the lower Hrazdan and Artashat irrigation canals and collector-drainage systems at the Ararat valley was explored, scientifically justified and recommended for implementation. Physiologically active anti-weed preparations have been applied. In the irrigation systems, where cane is also widespread, Arsenal New and Uragan Forte have been used, while in the over-moistened collector- drainages Uragan Forte and in the cane-free areas Epic (Sado) and Anchor 85 have been used. In the result of new technology application the irrigation water losses are reduced and the proliferation of weeds and field dodder towards the land user’s fields is prevented.

Artificial regulation and management of the numerical sex ratio of farm animals and poultry is one of the important prerequisites for intensive livestock management. The article considers the genetic characteristics of male turkeys produced via parthenogenesis and fertilized eggs according to blood serum transferrin (Tf), ceruloplasmin (Cp) and hemoglobin (Hb) loci. The findings of genetic and mathematical analyses conducted throughout experimental investigations can be used as genetic markers when implementing selection activities in the mentioned branch.

It is recommended to use the green tea infusion as a functional component and an improving agent to upgrade the baking technology. Upon the conducted research the efficiency of applying the mentioned tincture has been justified. The qualitative indices of the product have been determined through the methods regulated with generally accepted standards. According to the laboratory evaluations conducted for baking technologies the physicochemical and organoleptic properties of the finished bread products have improved upon the use of green tea infusion.

The aim of the research is to study the natural regrowth of the oak and to detect the most endangered forest areas. As compared to the data recorded in 1990, the oak seedlings and saplings have considerably decreased and unfavorable succession of tree species in the oak-forest have occurred as a consequence of adverse effect of human factor and improper forest management. To prevent the undesired processes it is recommended to conduct comprehensive research and to present scientifically justified reclamation ways.
