Growth Of Silvicultural Trees Planted As Shelterbelts And Windbreaks In Wadi Hadhramaut – Republic Of Yemen, Ahmed Salem Bataher
Hadhramout University Journal of Natural & Applied Sciences
The study had been conducted in Wadi Hadhramaut. Regular tree samples from windbreaks and shelterbelts had been collected for at least 3% sample size of each site while measurements of each tree were applied. High percentages of trees growth for height and stem diameter occurred in summer while crown width in spring. Evidence of measured trees in agricultural areas showed low and high figures of standard deviations ( ±0.538 - ±2.211m , ±0.539 -±3.289 m and ±1.652 - ±6.775 cm ) for height , crown width and stem diameter respectively, while the coefficient variation range of these characters were 7.06 …
