摘要

In this paper， we present a new procedure using an observer for estimating soil water content(swC), a key parameter of soils when dealing with the adaptation of water plant requirements within theframework of irrigation.Results showed that the estimation of SWC by means of the observer was good.On the one hand, the estimation of the unknown part of the soil-plant water balance equation (negativecomponent) has been found to be noise-free and values of evapotranspiration ET, drainage D, and runoffR。were estimated after filtering the simulated data. On the other hand, SWC has been found to increaseafter each water supply and decrease in the interval separating two successive irrigations. In addition,crop water requirements of avocado were found to be as much as 622 mm (for the 2016 dataset) and 380mm (for the 2018 dataset) during the growing season from June throughout September. The findings ofthis research helped accounting for the net water requirements of avocado with the aim to optimizeirrigation supply and provide guidelines to growers and farmers on sustainable irrigation of this cropunder Lebanon's Mediterranean climate and limited water resources.
