Effect of water conservation techniques on the establishment and growth of forest tree species in scrub zone
Raza-ul-Haq and Abdul Khaliq Chaudhry
ABSTRACT
The survival under different water conservation techniques i.e. contour trenches, micro-catchment and Gradoni was 79%, 78% and 82% respectively while in simple pits it was only 70%. The average highest survival percentage of three water conservation techniques was in E. camaldulensis (92%) and minimum with Acacia modesta (57%). The average height growth after 8 years of age of four tree species in contour trenches, micro-catchment, gradoni and simple pit was 4.74 m, 5.45 m, 5.30 m and 3.89 m respectively. Maximum positive response to the conservation techniques was observed with E. camaldulensis which gained almost two times more height (8.28 m) in 3 conservation techniques as compared to simple pit (4.63 m).
