“Ultra High Density Planting (UHDP) is a new technique developed especially for orchard trees, whereby fruit trees are planted at a closer distance than conventional spacing, combined with improved orchard management practices, for the purpose of utilising the natural resources of land, light, water and nutrients more efficiently, so as to achieve increased productivity. UHDP, combined with micro irrigation, canopy management by proper training, and pruning can play an important role in achieving quick, high, stable and sustainable yields in mango orchards,” said a statement.
TNAU has established a demo plot on 1.5 acres and has planted ‘Salem Bangalora’, ‘Imam Pasand’, ‘Banganapalli’ and ‘Bangalora’ varieties. The UHDP method of planting may help in increasing the productivity to the extent of 5-12 tonnes per acre; optimise use of vertical and horizontal space, increased water-use efficiency by reducing irrigation water use by up to 50 per cent and allows for inter cropping. The UHDP demo plot will be utilised for educating students and farmers, and also for conducting research studies. Mango, one of the most important fruit crops, is grown in an area of 1.6 lakh hectares. Major mango growing districts in Tamil Nadu are Dharmapuri, Krishnagiri, Salem, Vellore, Theni, Tirunelveli and Tiruvallur. Later, the governor conferred degrees on 2,589 graduates at the 40 convocation function at TNAU.
