EFFECT OF MICRO NUTRIENTS SPRAY ON FRUIT DROP, FRUIT QUALITY AND YIELD OF AONLA CV. BANARASI

An investigation was carried out during 2006 and 2007 to study the effect of boron (0.1, 0.2 and 0.3%), zinc (0.2, 0.4 and 0.6%) and cop per (0.1, 0.2 and 0.3%) along with a control on fruit drop, physical parameters and yield of aonla fruits cv. Banarasi. There were ten treatments tried in a RBD. All the characters studied were significantly improved by application of different micro-elements and their levels showing varying degree of their efficacy. The minimum fruit drop (56.84 and 50.22%), maximum length of fruit (4.01 and 4.10cm), breadth (4.31and 4.35 cm), weight (46.85 and 47.34 g) and pulp content (44.66 and 45.16 g)were obtained under the foliar spray of zinc. Among the three con centrations, the higher level proved most effective in respect of all the characters. Zinc at its higher concentration proved the best treatment in improving the yield of aonla.
