Abstract

Permanent raised beds (PRBs) performance was variably affected by different renovation methods evidenced by changes of up to: 5% in bulk density, 47% in cumulative infiltration and 48% in water advance that resulted variations of up to: 31% in application efficiency, 13% in distribution uniformity, 26% in dry biomass and 27% in water use productivity. Freshly renovated PRB improved infiltration but negatively affected irrigation performance due to poor irrigation management.
