EFFECT OF MICRO NUTRIENTS AND PLANT GROWTH REGULATORS ON FRUITING OF LITCHI

The present investigation was conducted in the litchi orchard of the Farm Area of R.M.D., College of Ambikapur in the year 2007 to 2009 to assess the effect of micro nutrients and growth regulators on fruiting in Litchi cv. Ambika Li tchi -1. The application of borax 0.4 per cent resulted in maximum fruit set (41.20%), fruit retention (22.60%), size of fruit (4.10 cm × 3.10 cm),number of fruits per tree (4625), weight of individual fruit (21.05 g) and fruit yield (92.85 kg/tree). GA3 10 ppm also was found effective treatment to increase fruit set, fruit retention and size of fruit. GA3 20 ppm produce maximum number of fruit/tree and yield. Interaction between borax 0.4 per cent and GA3 20 ppm exhibited in maximum retention of fruit and fruit yield. Maximum fruit cracking of 13 per cent was ob served in borax 0.4 per cent.
