To study the effect of irrigation treatments on yield and quality of grapes.

Worldwide grape is
mainly produced for wine making. Approximately 71% of the total grape
production is used for wine, 27% as fresh fruit and 2 % as dried fruit (FAO,
2007). Presently, wine grape is cultivated in approx. 2500-2600 ha area with
crop yields being realised from 1800 ha area at present. But, it is likely to
expand in near future, as; the trade in fresh fruits is becoming more
uncertain with increasing trade barriers and narrow production window in major
export markets, necessitating a shift towards processed products.
The technologies for quality wine grape production are still in the nascent stage in India. In fact systematic research is lacking in production technologies for wine grape cultivation. Wine grape cultivation in India falls under hot climate, a category based on average growing season temperature (Jones, 2006). Cabernet Sauvignon is one of the wine varieties adapted to hot climate conditions. However, the cultivation practices being followed elsewhere are applied to our situation. This is not the right practice.
Most of the vineyards in India are drip irrigated. The advantage of this irrigation technique lies in the precise control over time, quantity and desired area of water application. Amongst the various inputs applied to the crop, water is the most important input. Judicial application of water will not only help in maximizing the scarce water resource but at the same time also help in minimizing the salinity risk.
