INFLUENCE OF GROWTH-REGULATORS, COBALT AND SILVER IONS ON FRUIT DROP IN MANGO (MANGIFERA-INDICA L)
Abstract
Pre-mature fruit drop decreases mango yield. The effect of aqueous sprays of 1-naphthaleneacetic acid (NAA), gibberellic acid (GA3), silver nitrate (AgNO3) or cobalt nitrate [Co (NO3)2], alone or in combination, on fruit retention in mango (cv. Sindhri) was studied. Spray was done : once when fruitlets were of pea-size and then two weeks later when fruitlets increased to marble-size. Compared to control, applications of Co (100 mg/L), Ag (100 mg/L) ions, NAA (20 mg/L) and GA3 (50 mg/L) enhanced fruit retention by 131,127. 100 and 50%, respectively. No additive effect was observed when these chemicals were sprayed in combination.
