It’s not advisable immediate pruning after harvesting the Grapes. Instead, the vineyard requires a rest period, which is crucial for success of the next season. The duration of this rest period depends on various factors such as the yield obtained, soil condition, vine health, and regional climate. Foundation pruning sets the base for the upcoming season, the rest period plays a vital role in management of foundation pruning.
Post-harvest, vines experience significant removal of nutrients. Therefore, subjecting the vineyard to stress during this period. During fruit production, the vine utilizes essential nutrients from its shoots, trunk, and roots. To produce one ton of Grapes, the vine consumes approximately:
Nitrogen (N): 4 to 8 kg
Phosphorus (P): 0.7 to 1.5 kg
Potassium (K): 3 to 9 kg
At stage of fruit maturity, efficiency of root declines, it is necessary to the roots to regain their functionality. Applying high-quality humic and fulvic acid-based products can stimulate new root growth, thereby improving nutrient absorption. Nitrogen is a natural stress released nutrient, but its effectiveness is short-lived. To enhance Nitrogen efficiency and reduce its loss, DMPP and NET technology have been incorporated into Novatec products.
Similarly, Phosphorus as a energy source for vines, helping them recover from losses caused by high-yield production. In many new Grape varieties or young vineyards (2 to 3 years old), continuous high yields can lead to weak trunks and reduced lustiness. If pruning is conducted in mid-April or May, the woody parts of the vine harden, and excessive heat can cause bud dormancy, leading to uneven sprouting.
Once new leaves emerge, they take around 20 days to become self-food production. Until then, they storage food in the vine. Therefore, effective rest-period planning is essential, By the time of Grape harvesting, older leaves lose their efficiency. To reduce leaf stress and enhance their functionality, the application of natural amino acids and cytokinins based product Basfoliar Alge SL is beneficial. The following combination can improve leaf lifespan and vine recovery:
Seawed-based Basfoliar Algae SL (2 ml per liter of water)
Fetrilon Combi 2 (0.5 g per liter of water)
Basfoliar Zinc WP / Basfoliar Zn Flo (0.5 gm per liter of water or 0.5 ml per acre)
Basfoliar Boro SL (0.5 ml per liter of water)
This combined treatment helps extend life of leaves , enhances functionality, and facilitates vine recovery. As a result, pruning leads to uniform sprouting, lustiness of arm and shoots. Formation of efficient root. Ultimately, the success of the pruning phase is determined by the planning and care taken during the rest period.
