The horizontal grape trellis system of the vineyard - pergola - cultivation has a number of advantages. Such farming techniques increase yields by 2-3 times in comparison with the vertical shoot position system and provide the best quality of grapes. But this grape trellis has a significant disadvantages, the care of vines grown on horizontal trellis is very time-consuming. The authors have developed a new type of horizontal grape trellises - the mobile low industrial and high garden pergolas. As a result, we get a high yield typical for the low industrial pergola, which is 2- 3 times higher than the yield obtained on the vertical grape trellis, and its maintenance is just as convenient and simplified as that of the vertical grape trellis. For both - low industrial and high garden horizontal trellises - a significant reduction in labor intensity is achieved, and in addition - for high garden pergola - a significant reduction of traumatic care. The presented projects are an environmentally friendly solution to the problem of increasing grape yields and reducing labor intensity - not associated with environmental pollution with chemicals. KEYWORDS: horizontal grape trellis system, vertical shoot positioning support system, mobile grape trellis, two plane vertical grape trellis, yields. --------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: 10-09-2021 Date of acceptance: 25-09-2021 --------------------------------------------------------------------------------------------------------------------------------------- I. INTRODUCTION Viticulture is one of the distinctive areas of agriculture, the products obtained from it are used for various agricultural purposes, for example: table grapes, wine, raisins, canning and others [1,2]. Taking into account the market economic needs of the world, most of the grapes produced are used for the production of alcoholic beverages, mainly wine raw materials (wine materials). Raw materials, that is, grapes, play a decisive role in the development of winemaking, therefore in viticulture, as well as in all fields of agriculture, one of the main tasks is to increase productivity and product quality, reduce its cost, which depends on many factors, including the quality performance of vine care, vine formation, vine training - green operations - pruning; spraying, mechanical and chemical tillage, fertilizer, irrigation, grape variety, etc. In all these directions, scientific-research works are being carried out to increase the quality of the grape and yields. The laboriousness (labor intensity) of working in the vineyard, its yield also greatly depends on what type of grape trellis is used in the vineyard [3,4]. Grape trellis is characterized by a number of positive characteristics: 1. Grape trellises allow us to properly form the frame of a vine in the first years and then maintain its shape; 2. Distribute the vine buds evenly over the flatness of the trellis, so that all the leaves get as much sunlight as possible; 3. Convenient construction of trellises makes it somewhat easier for the viticulturist to take care of the vines and harvest; The perspectives of the vine support systems developing –
