We have seen in some parts of this region how much organic carbon is needed by the soil and grape vines, there are many factors that contribute to the production of high-quality grape bunches, and various nutrients are needed, among the main nutrients are nitrogen, phosphorus and potassium. Calcium, magnesium and sulfur are secondary elements and many other micronutrients are required in a little more quantity. Grape vines require different nutrients at different stages of growth. Phosphorus is required for good growth of roots, whereas nitrogen + phosphorus is required for the physical growth of the vine and the formation of shoots and stems, and for the development and growth of pods, the elements of nitrogen + palash are always required. In general, varieties like Thomson, Sharad Seedless, Tash Ganesh, Sonaka etc. produce twenty to twenty five tons of good quality grapes per hectare, but using modern technology, depending on the variety, we have to decide how much (nutrients) fertilizers to give. Let's think about it from a different angle, a scientific analysis of grape bunches shows that 84.5% water and 14.5% solids of total weight are found in grape seeds, which means that 14.5% solids must be formed in grape seeds leaving water, and these solids are different. These nutrients have to be supplied during the two growing periods of April pruning and October pruning. Laghe and the rest of Ardhe Natra Ardhe Sphurad and Sampura Palash should be given at the time of October pruning. Generally, before October pruning, the total nutrients required by a grape vine is equal to the weight of dry ash burnt in a furnace along with the whole root of a grape vine. Now, the amount of nutrients or fertilizers to be given to any garden will depend on the age and extent of the vineyard, apart from this, we have to consider how many nutrients are left in the soil, for this, both the soil in the garden and the water we regularly give the garden should be tested in the laboratory before pruning in October. Doing is important. Before this, many grape experts have determined the amount of NPK to be given to the garden during April and October, 900 kg of nitrogen, 500 kg of phosphorus and 700 kg of palash per hectare, then the amount of NPK available in the soil in the soil test. After knowing the amount of water, that amount has to be subtracted from the total recommended amount. Moreover, it is important to check the water supplied regularly to the garden, because now the water is not as clean and fresh as before, especially if it is directly from the river or canal. , phosphorus, palash, calcium, sodium, magnesium, etc., many elements are found in the form of free ions and in large quantities, we are going to think about all these issues, how much and when to give nutrients, we are going to think about all these in the next section.
