Abstract : A study was carried out with mango cv. Parbhani Bhukshan in farmers orchard at Paralgavan village near Parbhani City (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 percentage of fruit retention after flowering stage and at pea, marble, half- and full-grown stages of the fruits, followed by triacontanol at 500 ppm and NAA at 40 ppm.
