The Grapevine and Negative Charge: Part 19
Hello fellow farmers, in yesterday's episode we have learned about the reasons and remedies for grape seed cracking due to extremely cold temperature, we are going to learn about cracking and many other types of deformities in grape seed. In grapes, there are mainly defects such as short berries, water berries, pink berries, stalk necrosis and green leaves. In this disorder of grape seed stem burn, from the time of adding sugar to the grape seed, white brown spots like the tip of the heel first fall on the stem and then they turn dark brown and as the ripeness increases, the size of these spots also increases and the bunches or beads are burnt. This deformity increases with maturity. This affects the transport of sugar, water and other components from the vine and results in soft, greenish, mushy, watery and consequently dry bunches of grapes. Ultimately this results in adverse effects on bunch fresh weight, juice yield, soluble sugars and color components such as anthocyanins, while increasing grape acidity. Quality yield decreases due to adverse effects on yield and quality of grapes. As a result, there are difficulties in producing exportable grapes. This disorder is associated with an imbalance of organisms and nutrients especially the ratio of potash calcium + magnesium.
Ammonic nitrogen and potash should be avoided. Both of these factors adversely affect the absorption of calcium. Mani 8 m. M. Spray calcium chloride 500 g / 200 liters of water while still in shape. After that 2 sprays should be given at 10 days interval. 10 m. M. Magnesium Sulphate spray should be given twice at 10 days interval after berry size. The quantity should be 5 grams of magnesium sulphate per liter of water. Spraying SV Ketone together with Magnesium Sulphate gives good results, at the same time SV Ketone works very effectively to keep the leaf load active. When the positive charge is active on the leaves, the negative charge is active on the roots. And the work of the roots is already going on.
