The objective of this investigation was to see the effect of nutrients viz., urea (1%), KNO3 (2%), calcium chloride (1%), borax (1%), multiplex (0.4%) and their combinations on fruit quality and shelf life of litchi cv. Rose Scented. The experiment was laid out in randomized block design which was replicated thrice with one tree per replication. The results indicated that among all the treatments urea 1% + borax 1% and urea 1% + calcium chloride 1% was found best. Minimum fruit drop percentage (55.30%), highest fruit retention percentage (44.70%), minimum fruit cracking percentage and highest yield (77.38 kg/tree) were observed in plants treated with urea 1% + borax 1%. In terms of physico-chemical characters fruit weight (21.50 g), fruit volume (19.87 ml) and pulp: stone ratio (4.67) were found maximum with minimum stone per cent (15.33%) with application of urea 1% + calcium chloride 1%. Maximum fruit length (3.78 cm) and fruit breadth (3.40 cm) was observed in treatments T7 (urea 1% + borax 1%) and T6 (urea 1% + calcium chloride 1%) respectively. Fruits treated with urea 1% + borax 1% gave maximum TSS (21.80 0Brix), ascorbic acid content (32.57 mg/100g flesh) and minimum acidity (0.47%) as compared to control. In case of storage characters, application of calcium chloride 1% and urea 1% + calcium chloride 1% resulted in minimum physiological loss in weight (4.68%) and decay percentage (17.12%), respectively.ennullThesis
