Grape is a shallow feeder. Light and frequent watering is better for grapes. Water requirements of grape are very high during berry growth. This period coinciding with hot and dry weather, more water is required at this stage. Least water is required during fruit-bud formation. This period if coincides with cloudy weather and rains, watering are totally to be stopped. Reduced irrigation during ripening, i.e. (one month prior to harvesting) improves the quality of grapes and hastens the ripening.
