Poor fruit set and retention followed by sun burning and cracking is a serious
physiological disorder in litchi which is causing significant economic loss. Besides
these, the pre-harvest quiescent infection with blight, anthracnose etc is also causing
huge losses at post harvest stage. Considering these problems an experiment was
conducted during 2010-13 to evaluate the effect of pre-harvest spray of various
chemicals on fruit quality, yield and storage life of litchi fruits. Eight chemical
treatments were sprayed twice on litchi fruits cv. Shahi, during fruit development
stage and observations related to fruit retention, sun burning, cracking, fruit weight
and other quality parameters were recorded and analyzed. The result showed that the
combined spray of carbendazim (0.2%) and KNO3 (4 and 2%) gave the highest fruit
yield (26.06 kg/tree) and increased fruit retention by 26.10%, whereas minimum fruit
cracking and sun burning (13.54%) was observed under combined spray of GA3 (50
and 100 ppm) and carbendazim (0.2%). The minimum fruit yield (18.01Kg/tree) and
maximum percentage of discarded fruits (36.53%) were recorded in case of control
(water spray). KNO3 treatments delayed the maturity of litchi fruits by 3.33 days
whereas GA3 has advanced the maturity by 2.67 days and also gave uniform colour
development. It has also been found that carbendazim treated fruits gave least decay
loss (5.56%) after 5 days of storage at ambient condition.
