Growth and Phytomass Production in Leucaena leucocephala Under High Density Plantations on Degraded Lands of Doon Valley

Studies on plantation of Leucaena leucocephala were conducted to establish linear prediction ,model of leaf/wood under three different spacings i.e O.5m × O.5m, 0.5 × 1.0m and O.5m × t.5m on degraded riverbed soils of Dehradun. The studies showed that the prediction model of leaf/wood yield with all the three variables was the most reliable model in all the three spacings. The next best reliable linear prediction model ofleaf/wood yield was with two variables, One as height and another either basal diameter or DBH as predictors in all the three spacings.
