    Abstract In agricultural production, and in the specific case in viticulture production, the production of healthy food, that is the production of healthy plants and healthy and quality fruits, and especially the production of virus-free planting material, is still an actual problem. Global pollution has contributed to finding different innovative solutions in the production of healthy food and also in agricultural production and specifically in our trials in viticulture production, it is still very current of healthy and resistant plants and animals. In addition to the application of genetics and the selection of varieties, the choice of nutrition for the plant and the choice of soil improvers (part of the medium where the plant grows) are very significant in the problem. In particular, our investigations are aimed at improving the properties of the soil during the cultivation of rootstocks (mother plants) in viticulture production. The tests were carried out in the period 2017 - 2019, in the Skopje Vineyard. Grapevine rootstocks introduced in the Republic of North Macedonia were randomly selected. A significant segment in this treatment is that our "new formula" of the mineral zeolite, which is currently being tested in our laboratory, was used. This agent has proven to be very safe for use as a preparation for improving the properties of the soil, and also as an effective agent for protecting and improving the resistance of the grapevine rootstocks to diseases and pests. The treated plants had a better habit and better resistance to external conditions. This preparation is very suitable for use in organic production.

    The grape production together with the wine industry contributes about 20% of the total agricultural GDP in the Republic of North Macedonia and occupation of around 30,000 rural households. Due to the Covid-19 pandemic crisis and the instability of the world situation, the prices of raw materials in agricultural production are constantly increasing. Hence, the main goal of this paper is to assess the impact of the global economic crisis on the production price of wine grape varieties. The main approach of the comparative analysis for the production prices between the reference years 2020 & 2021 and estimated 2022 is based on established normative calculations of grapes within the Institute of Agriculture. The total costs are calculated based on variable and fixed costs of grape production. The investment and inputs costs are collected by commercial companies, suppliers of raw materials and farmers. The findings demonstrate that the average production price of grapes at total costs for 2020 & 2021 accounts in average 0.30 EUR/kg. The results from the estimations of the production price of grapes for 2022 show increase by 20%, which implies that the economic crisis has a large impact on the viticulture and wine industry. It is anticipated that the socio-economic situation of grape producers will be negatively affected. Therefore, the public policies for development of this important sector for the Macedonian agriculture should correspond to the new situation.
