STANDS DENSTIY INDEX OF Eucalyptus camaldulensis Dehn. IN THE IRRIGATED PLANTATION OF NINEVAH

Nonlinear mathematical models were used to develop regression equation by relating the mean diameter square as a dependent variable and number of trees per hectare as the independent variable. As a result the nonlinear regression equation screened was N=EXP (7.02906-0.03638 Dq) The statistical char...
