Water production functions in kiwi

The response of kiwi plants (Actinidia deliciosa) to different levels of water application under drip and microjet irrigation methods was studied over a period of 3 years, to determine water-production relationships. Fruit production increases as larger volumes of water are applied up to a level equivalent to 100% of pan evaporation. In addition, water management has an important effect on kiwi fruit production. Evapotranspiration in kiwi orchards increases with increasing levels of water applied. The evapotranspiration is dependent on water demand, applied water, irrigation method used, canopy cover, and water management.
