Performance evaluation of Chrysopogon zizanoides under urban conditions of Kuwait

الملخص EN

Plant physiological and morphological attributes should be critically evaluated for selecting any species for landscaping projects.

The selection of a species should be based on the evaluation of its adaptability, noninvasiveness, growth potential, and performance under the prevailing local arid conditions for their aesthetic looks, soil stabilization, and afforestation values.

Chrysopogon zizanoides (Vetiver), is suitable for Kuwait because it can withstand fluctuating temperatures ranging from 14 to 55 ◦C with unique physical and physiological characteristics.

Despite the successful growth performance of Vetiver in landscaping projects mostly in several tropical countries, it has not been utilized and evaluated in the Arabian Gulf region.

The objective of the current study was to evaluate the performance of selected ten cultivars of Vetiver (ODV-1, 8, 9, 13, 17, 21, 23, Silent Valley, Urlikal, and Pannimedu) in the deficient soil and environmental conditions of Kuwait in urban landscape at minimal maintenance.

It is suggested that based on visual greenery effect and overall growth performance cultivars, Pannimedu, Silent Valley, ODV-13, ODV8 and ODV-9 can be considered for landscaping projects in Kuwait.

To obtain the superior crown volume) which considers height and canopy) cultivar Pannimedu is suggested and to get a bushy growth (considering the number of tillers) cultivar ODV-13 and ODV-8 is found to be suitable.
