II.      a) Days after pruning:  < 7 days

b) Expected growth stage of the crop: Dormant bud (Foundation pruning)


III.     Water management (Dr. A.K. Upadhyay)

Expected pan evaporation:  7 to 11 mm


Amount of irrigation advised

  1. Rest period:  There is need to provide need based irrigation to protect the existing leaves from drying, so that it will contribute towards increasing the reserves of the vines through photosynthetic activity.   The quantum of irrigation water applied should be approx. 5000 L/ acre, twice in a week.  Care should be taken to reduce/stop the water in case new growth is observed on the shoot.

  2. After Foundation pruning, apply 11,900 to 15,300 L/acre per day during shoot growth stage for vineyards in Nasik and Pune, 15,300 to 18,700 L/acre per day for Sangli, Bijapur and Hyderabad regions during shoot growth stage.  For Solapur, apply 17,000 to 18,700 L/acre per day during shoot growth stage.

  3. In case there is probability of less irrigation water availability, then flood the bund (not whole vineyard) at pruning and mulch the bunds.  Mulching will reduce the evaporation of water from soil surface.  Flooding the bund will wet the deeper layers and thus, also reduce the evaporation losses.  Thus, this will reduce the salt load in the soil and at the same time saturate the soil leading to proper sprouting.

  4. Cover the cordons of the pruned vines with shadenet, if available, for uniform sprouting as well as reducing the irrigation water needs by 20-25 %.  Shadenet coverage will reduce the temperature impact on the cordons.  However, remove shadenet after 3-5 leaf stage.

  5. If shadenet is not available, spray the cordons with water during the peak heat period i.e. 2-3 pm to reduce the heat effect on the buds.


IV.     Soil and Nutrient requirement (Dr. A.K. Upadhyay)

Rest period to Foundation pruning:

  1. Apply 10kg Urea, 10 kg DAP and 10 kg Sulphate of Potash/ acre in two splits every 15-20 days.

  2. The vineyards where sodicity problems are there, apply gypsum to the soil for removal of sodium from the soil exchange complex.  In case of calcareous soils, use sulphur for similar purpose.

  3. Before starting pruning, go for soil and irrigation water testing to plan for soil, nutrient and water management.

Foundation pruning season:


1.     Apply FYM/ compost/other organic sources including green manuring atleast 12-15 days before Foundation pruning.  If possible, mix 200 kg Single super phosphate in the FYM and apply in the soil.   Application of organics improves the nutrient and water retention in the root zone and reduces nutrient losses from the profile.

2.     If soils are calcareous in nature, then apply 50 kg sulphur between the vines in the soil. The sulphur should be properly mixed in the soil for improving its efficacy in taking care of calcium carbonates.  Mixing of sulphur in organics lead to better utilization of sulphur for reducing calcium carbonate in the root zone along with reduction in soil pH also.

3.     At shoot growth stage, apply 20 kg urea/ acre in 2 -3 splits after sprouting.  In case the soil is calcareous, use ammonium sulphate @ 30 kg/ acre in 2 -3 splits.  Donot exceed 65 kg urea or 100 kg Ammonium sulphate on per acre basis during shoot growth stage.  In case of vigorous growth of shoots, stop nitrogen application and wait for the growth to stabilize before resuming nitrogen application.

V. Requirement of growth regulators (Dr. S.D. Ramteke)

  1. Apply hydrogen cyanamide @ 20 ml/liter of water on dormant buds after pruning. This will help for early and uniform bud sprouting.

  2. Due to high temperature and low RH, the sprouting will be delayed. Therefore, apply water spray twice in a day (from 6th to 7th days after foundation pruning) at 11.0 am to 12.0 pm and again 3.0 to 4.0 pm. This will help to moderate the temperature and increase the humidity on the cordons to facilitate bud sprouting.



VI. Canopy management (Dr. R.G. Somkuwar)

Once the harvesting is over, the vines need to be given a rest for a period of about 15 to 20 days. During this period, the small quantity of fertilizers and irrigation should be given. Foundation pruning is to be done leaving one bud on the cane. This will help to achieve uniform bud sprouts. During coming week, the atmospheric temperature is expected to increase beyond 420C with R.H. less than 20%. This will delay the bud sprouts. Exposure of cordon in this high temperature for a longer period may lead to formation of dead arm. Such arms will not bear any canes resulting into the blind buds. To avoid these following measures can be taken:

  1. Irrigation to the vineyards 2-3 days before foundation pruning. This will help for active sap movement in the vines. Irrigating the vines will create enough moisture in the root zone.
  2. Cover the vines with shade nets or gunny cloth. This will reduce the temperature in the vineyard thus supporting for early bud sprouts.


VI.   Disease management (Dr. S.D. Sawant and Dr. Sujoy Saha)
