In order to improve the quality of the 'Hayward' kiwi fruit (Actinidia deliciosa C.F. Liaang et A.R. Feyguson), soil moisture controlling was examined for its effect on fruit quality and tree growth. Soil moisture was controlled by the authors by mulching soil from July to November using air permeable film (porous film) and impermeable film (polyethylene film). The results were as follows: (I) Keeping soil moisture at pF2.3-2.5 from July to August, and at pF2.7-2.9 from September to the harvesting, time (November) improved fruit carbohydrate content and brix after ripening. (2) A significantly high correlation was observed between the soil moisture and the leaf water potential. (3) Controlling soil moisture at over pF2.5 from July to August, resulted in lean branch diameters and poor shoot growth the following year
