Project title: "The role of soil microbiocenosis in composting the organic component of municipal solid waste in the Kakheti region".

Funding organization: Iakob Gogebashvili Telavi State University

Implementation period: 01.01.2023 – 31.12.2023

Abstract

 

The aim of the study is to study the role of soil microbiocenosis in the process of composting the organic part of solid municipal waste (SMW) and to determine the possibility of accelerating the process of composting plant waste by adding microbiological additives to the composting area. It is likely that their addition to the composition of production raw materials in the initial stages of the composting process will lead to the activation of microbial activity.

To achieve the set goal, the following tasks were implemented:

1.     Study of the composition of the soil microbiocenosis in order to use the inoculum and production raw materials for the preparation of a microbiological additive;

2.     Study of the effect of microbiological additives on the processes during composting of the organic part of solid municipal waste (SMW) in mesophilic regimes;

3.     Study of the conditions of composting processes with the introduction of microbiological additives with the main abiotic, biotic and maturity indicators.

Research project: "Elimination of sparseness in the vineyard and its influence on the productivity of grapes". 01.10.2021-30.09.2022

Project supervisor: Associate Professor Levan Shavadze

Project funder: Iakob Gogebashvili Telavi State University

The research aimed in the wake of modern challenges, to study and identify a better option from the Agro-technological measures for the introduction of rational Agro-technology for filling the sparse vineyard.

Project outcomes:

1.                The research project of the field direction of agricultural sciences "Elimination of sparseness in the vineyard and its influence on the productivity of grapes" funded by Iakob Gogebashvili Telavi State University was carried out within the specified time frame 01/10/2021 - 30/09/2022;

2.                At the end of the vegetation, the calculations showed that the overall bloom of the plants was 15%. Thus, out of 1211 seedlings, a total of 182 seedlings reached the end of vegetation. The expected result of the experimental study was an increase in the yield by 4468.7 kg, which would be a 100% result, however, as a result of the negative impact of climate change on agriculture and in particular on the vine culture, the potential increase of the yield by 668 kg was conditioned, which gives the possibility to increase the productivity of grapes by 15%;

3.                During the research, the negative impact of climate change on agriculture and viticulture was clearly identified, because at the beginning of the vegetation in spring when the temperature and soil moisture were within satisfactory limits for the plant, the bloom of newly planted seedlings reached 96%. At the onset of summer, when the air temperature increased, and the precipitation and, accordingly, the soil humidity decreased, bloomed seedlings began to wither, and at the end of the vegetation, the total number of bloomed seedlings was 15%. Based on all of the above, production should be recommended to organize irrigation systems in the vineyards, so that the seedlings planted on the sparse areas should be provided with moisture and their bloom, growth and development reach a satisfactory result;

4.                Prevailing winds have a significant impact on the bloom of seedlings, which causes the soil surface to dry out quickly. Therefore, it is necessary to arrange windbreaks so that newly established and full-harvest vineyards are protected from the negative effects of winds and, accordingly, the effect of the flowering and growth of seedlings increases at the time of filling in sparse areas;

5.                The agriculture of Kakheti region is severely affected by hail, which brings great losses to viticulture, it can damage and/or completely destroy the crop, it also has a negative effect on the vegetative organs of the vines and causes significant damage to newly planted vines. Although different methods are used to combat the negative effects of hail, production should be recommended to organize hail protection systems (anti-hail nets), which will protect more than 97% of both the crop and the plant and the newly planted vine;

6.                A sparse vineyard should be filled with grafted seedlings. The seedlings should be planted in pre-deeply cultivated soil with restored fertility according to the results of laboratory analysis in fall, winter or early spring seasons. During the active period of vegetation, the shoots on newly planted seedlings should be tied and wrapped on an individual support. Plant protection measures should be implemented in accordance with climatic conditions. Against droughts, the vineyard should be irrigated, preferably using a pre-arranged drip irrigation system.

Research title: "Influence of the cultivation of Kakheti industrial and promising grape varieties with different schemes on the chemical composition of wine materials"

Project supervisor: Doctor of Agriculture Manana Kevlishvili

Implementation period: 01.10.2020-31.03.2021

Project funder: Iakob Gogebashvili Telavi State University

 

Abstract

 

The aim of the project was to investigate the chemical composition of grape juice, wine, vodka and vinegar in the harvest obtained from different schemes of grape growing in the one-hectare educational research vineyard planted on the base of Telavi State University. Within the framework of the project, the study of the aboriginal varieties, "Akhmetis Tsiteli" and "Ikaltos Tsiteli", was presented, in particular, the analysis of the chemical composition of the grapes and their chemical composition was determined. Laboratory and practical research methods were used during the implementation of the project. A chemical study of the soil was carried out, the chemical composition of the wine materials in the grape harvest located in each variant was determined. The chemical composition of the grape juice of new varieties and the wine obtained from it was resolved. By 2020, the grape varieties grown in the vineyard under different schemes were harvested, and wine, vodka and vinegar were made from them. In 2021, there was a study of the chemical composition of grape juice and wine obtained by different technologies, we studied the quantitative content of different classes of compounds (esters, aldehydes, ketones, amines) with aromatic properties (esters, aldehydes, ketones, amines) in the saffron planted in a barrel with the help of an air (gas) chromatograph, as well as those containing different functional groups. Identification of organic compounds with nutritional value at different stages of planting, research of the vitamin composition of flavored wine, vinegar and vodka was carried out using liquid chromatography, the study of the dynamics of quantitative changes of some organic acids (citric acid, tartaric acid, malic acid) affecting the quality of wine made by different technologies from sweet to ready grapes to the product. Also, identification of the chemical composition of pesticides used in agriculture. After the completion of the research, a complete scheme of vine cultivation was outlined, which will give us an idea of ​​the nutritional value of the vine and the properties of the products obtained from the grapes. After the completion of the project, recommendations were made to the farmers about the vine cultivation scheme.

            The goal of the grant project was to develop a soil agrochemical cartogram of Tsinandali village with the involvement of students, which would be developed mainly as a result of soil research. For the preparation of the agrochemical cartogram, the research of the chemical composition of 250 hectares of soil, namely phosphorus, potassium and PH, was calculated, however, during the sampling, we studied and accordingly mapped the results of the soil research of 268 hectares. A land use map of Tsinandali was prepared, where the land area of ​​each farmer was marked and the laboratory research results were recorded. In particular, the following data were recorded in the form of fractions on each marked plot: Plot number Phosphorus (I, II, III, IV) Potassium (I, II, III, IV) where: I - very poor, II - poor, III - moderately provided, IV - provided. The map was given in printed form to the trustee of Tsinandali village, who made the information available to each farmer. Any farmer whose plot is included in the area we investigated can find out the state of his plot according to the content of nutrients that can be assimilated. Within the framework of the project, a brochure was printed with information on how farmers should search for data on the nutrient content of their plots and how to take further action so as not to pollute the soil by applying excess fertilizer.
