Estimated water requirements of some Malaysian commercial fruit crops

Wan Hassan W Dollah, . (1993) Estimated water requirements of some Malaysian commercial fruit crops. [Proceedings Paper]

Application of irrigation technology especially the micro irrigation system for fruits production in this country has started only recently i.e less than a decade ago. Realizing that irrigation can enhance crop growth increased and consistent yield and ensure better fruit quality irrigated fruit production will continue to increase at an accelerated rate. The benefits of irrigation can be fully exploited if proper system design and practice are adopted. Not withstanding the success of several irrigated fruit farms in this country experimental data on the crop water requirements of local fruit are not available. Knowledge of crop water requirements is essential in water resources planning irrigation system selection and design and as well as irrigation scheduling. Whilst waiting for experimental results which would take significantly long time it is felt that there is an immediate need to formulate practical estimate figures for design and management purposes.

Abstract

Application of irrigation technology especially the micro irrigation system for fruits production in this country has started only recently i.e less than a decade ago. Realizing that irrigation can enhance crop growth increased and consistent yield and ensure better fruit quality irrigated fruit production will continue to increase at an accelerated rate. The benefits of irrigation can be fully exploited if proper system design and practice are adopted. Not withstanding the success of several irrigated fruit farms in this country experimental data on the crop water requirements of local fruit are not available. Knowledge of crop water requirements is essential in water resources planning irrigation system selection and design and as well as irrigation scheduling. Whilst waiting for experimental results which would take significantly long time it is felt that there is an immediate need to formulate practical estimate figures for design and management purposes. This paper presents the estimated crop water requirements for every growth stage of some 15 local commercial fruits. It is a useful guide particularly to agricultural/irrigation engineers irrigation designers agronomists and farm managers. These values were obtained through mathematical computations applying micro irrigation system approach. They were based on a number of estimated parameters. The most important input parameters were reference evapotranspiration ETo crop coefficient Kc crop spacing and percent are shaded by the canopy. Crop water requirements were tabulated into four different groups according to four broad agro-ecological zones. However judicious use of these figures is recommended before a more refined data are avalaible through field measurements
