 Note: Above weather information is summary of weather forecasting given in following websites

II.      a) Days after pruning:  123 days

b) Expected growth stage of the crop: Post cane maturity resting stage

     

III.    Nutrition and irrigation management (Dr. A.K. Upadhyay)

 Water management

Expected pan evaporation:  3 -5 mm

  1. All the grape growing regions are forecasted to receive from drizzle to light rains.  The irrigation water application should be based upon the growth of the vines.  Generally, under wapsa (field capacity) condition of the soil, donot apply irrigation.  In general, there will not be any need to provide irrigation in areas which have witnessed continuous rains since last 3-4 days.

  2. Provide irrigation through drip @ 2800 - 4000 litre/acre/day in case no rains are received.  Observe the vine growth before irrigation water application.

 

Nutrient management

  1. After Cane maturity stage, fertilizer application is over.  Look for the sodicity problems. Soil, petiole and water reports will give information on extent of build up of sodicity in soil.  Apply gypsum to the soil for removal of sodium from the soil exchange complex.  In case of calcareous soils, use sulphur for similar purpose.  Gypsum/sulphur should be properly mixed in soil.  The soil should be moist.  After  approx. 20 days adequate irrigation should be provided to leach sodium from the soil.

  2. If fruit pruning is scheduled in next 15-20 days, test your field soil and irrigation water and plan nutrient management accordingly.

  3. In case fruit pruning is planned during mid September, raise Sunnhemp or Dhaincha for green manuring purpose.  For sodic soils, growing dhaincha will be beneficial.

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

Nil.

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

 

1.   Rootstock management:

            During this period, the weather is favourable for grafting of commercial variety on rootstock. As per the present weather the temperature is about 300C while the relative humidity is above 90%. This condition will help for graft success. At the time of grafting, the rootstock must be in sap flow condition. Under the condition of no rainfall, it is advised to irrigate the rootstock plants 4-5 days in advance. Irrigation after the grafting will help to build the relative humidity required for successful grafting. 

 

 

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

 

Days after pruning

Risk of diseases

Downy mildew

Powdery mildew

Anthracnose

Others (specify)

123 Moderate High Low

Low

bacterial leaf spot

 

There can be a high incidence of powdery mildew with the rains having stopped in most of the grape growing areas  and application of sulphur 80WDG @ 2g/L or dusting of sulphur 80%WG @ 5-6 kg /acre should be done for the control of powdery mildew. Chitosan may be tank mixed with sulphur @ 2g/L.In Nashik region, downy mildew may be incident and hence application of potassium salt of phosphoric acid @2g/l +Mancozeb @2g/L may be done..

 

 

VII.    Insect and Mite management. (Dr. D.S. Yadav)

 

 

 

 

 

 

 

       





Crop advisory relevant to different places is prepared by experts, considering forecasted weather, crop growth stages in majority of vineyards and ground information on incidence of different conditions in different grape growing areas received from regular interaction with progressive grape growers. No claims are made on its correctness.
