Resumen
Descripción
Melia dubia Cav., member of family Meliaceae, found upto 1800 amsl in India and thrives well under variety of soils and climatic conditions. The short rotation indigenous tree meets raw material requirements of timber, veneer, ply and paper industries. Forest Research Institute, Dehradun, India has released ten cultivars for commercial cultivation with excellent bole form and average productivity of 34.57 m3ha-1 yr-1. These varieties are not only potentially contributing in supply of raw materials to different industries but also pivotally reducing foreign exchange. Though evaluated germplasm consisted exceptional variability for pulping parameters, few genotypes were found utmost suitable for paper manufacturing with pulp yield upto 55.32 %.The general purpose plywood (interior grade) was found to meet IS specification, and Progeny No. FRI/MD/104 performed with maximum modulus of rupture and modulus of elasticity along and across the grains, followed by Progeny No. FRI/MD/028, FRI/MD/075 and FRI/MD/076. Additionally, ply made from wood of Progeny No. FRI/MD/028 and FRI/MD/076 performed suitably in dry and wet state glue shear strength. The ply manufactured from this wood fetches handsome price in the market with low maintenance expenditure. Economically, plantations of the species are most suited to growers and when planted in rows along the field bunds about 60 trees can be planted per acre generating an income of about Rs. 2 Lakh in sixth year of planting. On the other hand, planting 300 to 400 trees per acre in blocks give a minimum profit of Rs. 1 lakh per year from an acre. Under good maintenance and controlled irrigation from sixth year onwards, trees with about 100 cm GBH and clear bole of 5 to 7 meters can fetch upto Rs. 4000 to Rs. 5000 per tree depending on soil depth and quality. Furthermore, total carbon stock and CO2 sequestration potential of improved varieties calculated substantially higher to the tune of 17.90 and 82.80 t.ha-1 yr-1.
