Abstract

Due to their importance in enhancing greenery activities in Kuwait, ornamental plants from diverse origins are being introduced and evaluated for their suitability to the harsh climatic conditions of the country. Introduction of multipurpose plants such as Capparis spinosa provides an invaluable opportunity to enhance greenery in Kuwait, while at the same time, exploring other applications, such as fruit and feed production. The objective of this study was to conduct field trials to evaluate the adaptation and performance of Capparis spinosa, as well as identify irrigation water requirements for water conservation aspects. Hardened Caper seedlings were drip irrigated at 100, 75 and 50% of the daily water requirements. Irrespective of the treatments, the survival of the plants recorded 100%. Though the canopy growth rate was highest in plants with 100% irrigation, no significant variation in canopy was observed in plants with 50 and 100% irrigation. The results signify that caper plants can be grown and sustained successfully with 50% of its daily water requirement. Caper plant is a potential candidate for introduction into greenery projects as a ground cover because of its ability to grow under conditions of aridity.

Key words: Capparis spinosa, greenery activity, ornamental plants, field trials, water conservation.
