Growth Rate, Basal Area and Volume of Corymbia Citriodora and Cupressus Sempervirens Irrigated With Treated Wastewater at Serabium Forest

Abstract

erabium forest is 15 km. far from Ismailia City at the Northern East of Egypt, which had 25 years old, irrigated by treated wastewater.The Serabium forest (129 ha) was realized using different tree species a high wood production. The study was carried out from 2009 to 2013 on four years old of Corymbia citriodora Hook. and Cupressus sempervirens L. trees planted at 3 х 3 m. spacing and irrigated by drip irrigation system of primary treated wastewater to compare the growth and wood prduction of two species. The results revaled that, the growth of two tree species increased gradually through 5-year affected by treated wastewater. Corymbia citriodora had tallest significant trees and biomass as compared to Cupressus sempervirens. The results also showed that, Corymbia citriodora trees gave the highest significant annual rate increment of basal area in 2010 (39.03 cm² tree1) followed by Cupressus sempervirens (25.24 cm² tree1). Although, Cupressus sempervirens had the highest tree volume at 2009 as compared to C. citriodora (12283.6 and 4612.6 cm³ tree1), respectively. C. citriodora showed the highest significant tree volume in 2012 and 2013. At the end of the experiment, Corymbia citriodora gave the highest values of total volume per hectare followed by Cupressus sempervirens (79.43 and 49.18 m³ hā ¹), respectively. It could be concluded that, Corymbia citriodora gave the best growth performance followed by Cupressus sempervirens, which makes these species a valuable in many reforestation programs, especially Corymbia citriodora for shortcut rotation and Cupressus sempervirens for long cut rotation.

A Review: Long-Term Impact of Recycled Wastewater Irrigation on Woody Forests

“…Deficiency, as properly as immoderate doses of sure metals can have a terrible effect on the physiological ability to grow plants, posing viable risks to human beings and the surroundings (Feng et al, 2010). It used to be stated that primary wastewater irrigation boosted the growth, backside space, and trunk extent of positive tree woodland species (Ghorab et al, 2011). Forest structures are used with the aid of fifty-one municipalities to deal with essential and secondary municipal Heavy metal contamination in woody forest plants:-…”

Growth Study of Some Local and Exotic Timber Tree Species Irrigated With Treated Waste Water

“…However, for the number of branches, the highest number was observed from K. senegalensis and A. indica trees, while C. citriodora, A .indica and G. arborea trees were the highest percentage of survival. It can be said that some tree species had the most ability to grow and to withstand the conditions of irrigation with treated waste water (Cornelissen et al 1997;Adrover et al, 2008 andGhorab et al, 2017).…”

Effect of Using Treated Sewage Water on the Yield of Some Tree Species Compared With Those Irrigated by Fresh Water

“…The effect of soil media on growth and chemical wastewater) on growth, and chemical composition of some woody tree seedlings, growth parameters increased significantly in all seedlings by using wastewater than tap water. Ghorab et al (2011) mentioned that the primary wastewater irrigation increased biomass, basal area and stem volume of some tree forest species. The superior effect of the treated wastewater, compared to fresh water irrigation, may be attributed to the ability of negatively charged particles of organic matter to attract and hold positively charged cation, which allows high availability of water and nutrients to the roots.…”
