Effect of Paclobutrazol Application on Nutrient Dynamics, Vigour and Fruit Yield in 'Alphonso' Mango (Mangifera indica L.)

Application of Paclobutrazol to 22 year-old 'Alphonso' mango trees significantly retarded plant height, plant spread and tree volume. Number of flushes and vigour of emerging new flush also decreased significantly besides production of fewer leaves, reduced leaf area, twig length and dry m...
