Response of yield and quality attributes of litchi cv. Dehradun to soil and foliar application of boron

A field experiment was conducted during 2005 and 2006 at Regional Horticultural Research Station, Jachh, Kangra, Himachal Pradesh to evaluate response of boron application on fruit yield and quality of litchi cv. Dehradun. Experiment comprised of foliar application of borax @ 0.2, 0.4, 0.6% and soil application of borax @100, 150, 200 g/tree in pre bloom stage. Borax applied at the rate of 0.4% in mid February and 1^st week of May as a foliar application, resulted in highest fruits set (59.00) per panicle, fruit retention (22.58%), fruit yield (18.08 kg tree⁻¹), lowest fruit drop (77.42%) and fruit cracking (7.47%) indicating better response of plants to foliar application of boron as borax @ 0.4%.
