Pre-harvest foliar application of nutrients in litchi (Litchi chinensis Sonn.) in order to improve its quality and shelf life

The present investigation was carried out at Horticultural Research Centre, Pattharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District- Udham Singh Nagar, Uttarakhand during April to June 2015. 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. In terms of physico-chemical characters fruit weight (21.50 g), and fruit volume (19.87 ml) were found maximum with minimum stone per cent (15.33%) with application of urea 1% + calcium chloride 1%. Fruits treated with urea 1% + borax 1% gave maximum total sugars (13.86%) and reducing sugars (12.30%) 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. | Pre-harvest foliar application of nutrients in litchi (Litchi chinensis Sonn.) in order to improve its quality and shelf life
