| dc.description.abstract | An investigation entitled Studies on extension of harvesting span of litchi (Litchi chinensis Sonn.) cv. Rose Scented was conducted on twenty year old litchi trees during 2006-07 at the Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand). The experiment consisted of 10 treatment [Shade net, 30% (T1), Shade net, 50% (T2), GA3, 20 ppm (T3), GA3, 40 ppm (T4), BA, 20 ppm (T5), BA, 40 ppm (T6), KNO3, 4% (T7), Perforated polyethylene bagging (T8), STS, 10 m Mol (T9) and Control (T10)] in Randomized Block Design with four replications. Findings revealed that the application of KNO3 @ 4% resulted in significantly more fruits set per panicle (64.93). Maximum fruit drop of 79.05 per cent was observed under control while under shade net (30%) 71.91 per cent fruit drop was checked. Shade net (50%) checked the fruit cracking (4.49%) whereas, maximum fruit cracking took place in untreated trees. The maturity span was advanced by 2 days under KNO3 @ 4% and delayed by 16 days under shade net (50%). Significantly more fruit yield per tree (116.50 kg) was recorded in shade net (50%). Treatment of GA3 (40 ppm) being at par with BA @ 20 and 40 ppm exhibited significantly more TSS, total sugars and non-reducing sugars. Application of KNO3 @ 4% exhibited significantly highest reducing sugars and significantly lower titratable acidity, however, difference in ascorbic acid content were found to be non-significant among different treatments. Maximum net profit of Rs. 717.35 was gained from GA3 @ 20 ppm treated trees but application of KNO3 @ 4% resulted in loss of Rs. 227.50 per tree. From the present study it might be concluded that the harvesting span of litchi may be advanced or delayed by the application of KNO3 (4%), shade net (30 and 50%) and silver thiosulphate (10 m Mol), respectively. Maximum net profit is obtained through application of GA3 (20 ppm) at two weeks before harvesting. | en_US |
