Preventing grape vine from freezing in winter by plastic film cover

Bind pruned grapevine collecting it from grape trellis and cover it with a 20 cm thick grass covers. It is watered twice and covered with plastic film during winter.

Method to stimulate advanced fruiting of the grape vine

During summer season, select new branches of grape vine, which have grown longer than 1 m and thick parent branches. Put them down from trellis and cut the bud at the end of those branches. Then, bury them 25 cm deep into mud and keep the end of the branches out of the mud. After that apply regular water, spray fertilizer and pesticide. The branches grow roots in the same year. Plant these branches with their root in the next year. This way gives higher survival rate and fruit bearing is advanced by a year.

Spray glucose liquid for good yield of grapes

Better yield of grapes can be harvested if sprayed with glucose liquid (1:800 glucose/ water ratio) during blooming, fruiting and harvest stages. It gives still better results if the liquid is further mixed with phospho-dihydroxy-potassium at a rate of 3000 g/ha..

Method to produce seedless grapes

1. Make a mixture of 1 gm giberellin and 10 liters of water. Put the flower head into mixture for 10 minutes about 2 weeks before the blossom stage. Repeat the same process 12 days after the end of blossom stage.

2. Make a mixture of 100 ppm giberellin and 400 ppm streptomycin and repeat the process at the same period as mentioned above. The use of this mixture can render 90% of the grapes seedless.

However, no bordeaux mixture should be sprayed 5 days before and till 2 days after the above treatments. If it rains soon after the above procedures, they should be repeated.
