Abstract : A study was conducted in mango cv. Parbhani Bhushan orchard at Paralgavan village near Parbhani (Maharashtra, India) during 2002-03. Ten years old mango trees, spaced at 10×10 m, were sprayed with chemicals KNO3 (at 2.0, 4.0 and 6.0%) and urea (at 1.0, 1.5 and 2.0%), and growth regulators NAA (at 40, 60 and 80 ppm) and triacontanol (at 300, 500 and 700 ppm) at flowering stage and when the fruits were of pea and marble sizes. Triacontanol at 700 ppm recorded the highest values for fruit length (10.91 cm), breadth (8.91 cm), volume (336.58 cc) and weight (330.41), followed by triacontanol at 500 ppm and NAA at 40 ppm. Triacontanol at 700 ppm showed the maximum mesocarp percentage (69.91%), followed by NAA at 60 ppm. The maximum exocarp percentage (19.83%) was recorded from KNO3 at 4.0% and the minimum (16.83%) from NAA at 80 ppm. The least stone (endocarp) percentage (12.00%) was observed with triacontanol at 700 ppm and the maximum (17.33%) with NAA at 80 ppm. The highest percentage of total soluble solids and ascorbic acid were recorded in trees treated with triacontanol at 700 ppm (18.91% and 39.75 mg/100 g), followed by those treated with triacontanol at 500 ppm and NAA at 40 ppm.
