Abstract : Field experiment was conducted during 2003-07 to study the effect of different doses and sources of potassium on yield and quality of 'Alphonso' mango (Mangifera indica L.). The pooled results of this experiment revealed a new recommendation to mango growers as soil application of 50 kg farmyard manure, 1.5 kg N, 0.5 kg P2O5 and 1.0 kg K2O in the form of sulphate of potash/tree in first fortnight of June and application of paclobutrazol @ 0.75 gai/m canopy diameter during second fortnight of July to first fortnight of August with three foliar sprays of 0.9% K2SO4 at peanut, marble and egg stage of fruit development to increase yield and quality of 'Alphonso' mango. This treatment increased flowering (3.92%), fruit retention (45.45%), fruit yield (26.11%), fruit weight (14.48%), shelf-life (10.09%) and reduced spongy tissue (122.35%) over the control.
