Viticulture in the world is gaining popularity for multidirectional uses of grapes. Demand of fresh grapes in the world market is an increasing trend while its production in the commercial sector in many countries like India is now more or less in a stable position due to speedy urbanization. In order to minimize the gap between demand and supply, new areas to be explored for grape cultivation. With the view to introduce and commercialize the grapes in western part of West Bengal (India) where a vast area is available and agro-climatic conditions indicated its suitability, long term investigation on various aspects was initiated at the university and government farms and also in private sectors. Varietal suitability is considered to be the first step for commercialization of a crop. Introduction of 30 good grape cultivars and evaluating them for more than five years indicated that 'Arka Neelamani', 'Pusa Navarang', 'Pusa Urvashi', 'Arkavati', 'Arka Kanchan', 'Arka Shyam' and 'Arka Trishna' were the most promising cultivars in respect to yield, fruit quality and disease and pest reaction. Results from the pruning trial indicated that pruning on 30 January was the best among 4 other dates tested. Increased spur fruitfulness, yield and fruit quality. Smearing of H2CN2 at 30 ml/L was the most effective compared to other chemicals. Higher fruit set was obtained with the application of GA3 at 20 ppm while better quality bunch was recorded from 40 ppm GA3. Induction of seedlessness was possible in seeded cultivar like 'Arka Neelamani' by pre-bloom application of 400 ppm GA3. Spraying of 200 ppm BA at 25% colour breaking stage resulted in uniform colour development of berries with higher TSS/acid ratio. Source

Pomegranate (Punica granatum L.) is one of the favorite table fruits in the world for its nutritional and medicinal properties. There are many untapped areas in India like the laterite zone of West Bengal and its adjoining states where pomegranate cultivation is explored for its commercial feasibility. Results from crop regulation by pruning showed that November pruning was the best to obtain highest yield of quality marketable fruits. Study of diverse nutrient management options found farmyard manure was better than vermicompost and improved responses to inorganic fertilizers, resulting better plant growth, highest yield with quality fruits which was associated with the foliar N/K ratio of 1.1. The fruits from organic sources of nutrients showed maximum storage life with less W.L. To harness the beneficial effect of bioregulators, the results indicated that 3 sprays of NAA at 20-25 ppm were the best in all respects of productivity and quality. For colour development, pre-harvest spraying of fruits with KH2PO4 at 1 g/L induced attractive reddish colour both in skin and aril. The second most important was by newspaper wrapping of fruits.

Considering the wide gene diversity in wood apple, an extensive survey was made and seven accessions have been collected. The age of the plants varied between 13 and 70 years with yield potentiality in mother plants varied from 650 to 1085 kg/plant. The fruit weight ranges between 130 to 225 g, pulp percentage was 42.9 to 60.6%, T.S.S. ranges between 15.0 and 18.4 Brix, acidity 1.7 to 4.6% and total sugar content varied between 5.1 and 14.3%. To multiply the elite mother plants for commercial multiplication, a propagation trial was conducted for 2 successive years. The results indicate grafting was the better as compared to budding and 85 to 95% success in grafting was recorded when operation was performed in September. For processing fruit pulp, wood apple - squash was prepared using xanthan gum and red chili powder. The product could be stored for 150 days in an acceptable condition. The wood apple squash with 15% TSS, 1% acidity, 35% pulp and 0.35% xanthan gum scored the highest for overall acceptability. Source
