Abstract
Water requirements of pear William on a loamy sand soil were investigated at a high tree density orchard using micro-sprinklers at different pre-irrigation soil moisture.
From flowering to ripening or picking, water requirements of pear William were 470 mm plus or minus 5–10%. Precipitation outside this period (220–330 mm in the investigated years) must also be taken into account.
On loamy sand soils, the lower limit of optimal soil moisture is 50–60% of the FWC. The irrigation requirements ranged between 140 and 360 mm, depending on the amount and distribution of precipitation in a particular year.
The yields were high and stable, ranging from 37.086 and 44.080 t ha-1. The extra and first class quality of fruits exceeded 80% of the total yield.
