Abstract
Allometric equations were developed to estimate aboveground phytomass of Prosopis juliflora (Swartz.) DC using regression models
based on height, crown diameter, basal area of stem, stem diameter etc. These equations predicted phytomass of individual plants or
the components of the plant. Dry firewood mass of P. juliflora (loge transformed) was best estimated with a quadratic model based on
height, quadratic and power model based on stem diameter and through power models based on basal area and the crown cover of the
plant. The multiplicative models were also equally good. Multiple regression model based on linear combination of untransformed
independent variables viz. height, Canopy cover, stem diameter and basal area of the plants estimated log-transformed total fresh
phytomass of the plant better than the log-transformed dry firewood component.
