IMPACT OF VARIOUS NUTRIENT SUBSTANCES THROUGH FOLIAR SPRAY ON GROWTH AND REPRODUCTIVE ATTRIBUTES IN MANGO (MANGIFERA INDICA L.) CV. MALLIKA

The present study titled Impact of Various Nutrient Substances Through Foliar Spray on Growth and Reproductive Attributes in Mango (Mangifera indica L.) cv.Mallika was conducted at Kittur Rani Channamma College of Horticulture, Arabhavi, during the year 2023-24.Mango trees, were planted at a spacing of 10 m 5 m, with eight treatments involving various concentrations of nutrient solutions like Novel organic liquid (Navsari) @ 1 and 2 per cent, Multi micronutrient fertilizer for mango (Multiplex) @ 0.25 and 0.5 per cent, Sea weed extract (IFFCO) @ 1 and 2 per cent, and Mango special (IIHR) @ 0.50 per cent in a Randomized Complete Block Design (RCBD) with three replications.Four foliar sprays were administered according to the treatments.Among the various nutrient treatments, T 2 -Novel organic liquid (Navsari) @ 2 per cent showed the most significant improvement in tree height (6.86 m and 7.66 m) at three months and six months after spray respectively with an incremental increase of 1.52 m.Canopy volume (6.09 m 3 ), early flowering (77 days), greater number of panicles (86.66), maximum hermaphrodite flowers (29.92%), highest fruit set (14.95%), fruit retention (8.64%) and minimum fruit drop (91.36%) also recorded in treatment T 2 compared to the other treatments.
