Water savings, nutrient leaching, and fruit yield in a young avocado orchard as affected by irrigation and nutrient management'
This project was designed to determine the effect of fertilizer rate and irrigation scheduling on water use, nutrient leaching, and fruit yield of young avocado trees (Persea americana Mill. cv. Simmonds). Seven nutrient and irrigation management practices were evaluated: (1) irrigation based on crop evapotranspiration (ET) with 50% fertilizer at a standard rate (FSR); (2) ET irrigation with FSR (typical for avocado production in the area); (3) ET irrigation with 200% FSR; (4) irrigation based on
Water management and salinity adaptation approaches of Avocado trees: A review for hot-summer Mediterranean climate
The production and consumption of avocado has increased significantly over the past years, experiencing a steady expansion into new markets around the world. This review paper focuses on avocado cultivation in its new markets with hot-summer Mediterranean climate. A significant literature gap exists on the viability of this crop in such data environments which experience limited availability of water in the summer exacerbated by climate change and potential salinity issues in irrigation water, typical
An irrigation schedule testing model for optimization of the Smartirrigation avocado app
A series of mobile irrigation apps have been developed on the basis that irrigation schedules can be estimated using an average of the previous five days of crop evapotranspiration (ETc). The application of this average ETc methodology for developing an irrigation schedule has not been fully evaluated for the suite of apps, including the avocado app. Thus, an irrigation testing model was developed and is presented here that simulates irrigation depths based on the Smartirrigation avocado app operation
Water-use, wetted soil volume, root distribution and yield of avocado under drip irrigation
The effect of three water use (WU) levels corresponding to 0.3, 0.6 and 0.9 Ep (Ep=Evaporation ''A'' pan) on wetted soil volume, root distribution and yield of avocado cv. Fuerte was investigated over a 5-year period at Chania, Greece.The average amounts of irrigation water applied annually (in addition to rain) for the three WU levels were 238, 553 and 868 mm, respectively. Soil volumes, with a volumetric soil water content percentage (theta) corresponding to a soil water potential (psi(s)) higher
Yield and fruit quality of avocado trees under different regimes of water supply in the subtropical coast of Spain
The subtropical Mediterranean climate of southeastern Andalusian coast allows Spain to be the largest European producer of subtropical fruit, with the avocado as the main representative. In this region, precipitations are scarce and erratic and limit water availability for irrigation. Under this climatic uncertainty, appropriate water use is required for assuring crop environmental sustainability and increasing water productivity (WP) of avocado orchards. For this purpose, it is necessary to evaluate
Mitigating negative effects of long-term treated wastewater application via soil and irrigation manipulations: Sap flow and water relations of avocado trees (Persea americana Mill.)
Recent studies have shown significant negative effects of long-term irrigation with treated wastewater (TWW) on performance of orchards planted on clay soil. The aim of this study was to evaluate water use and water relations of different mitigation measures to remedy the declining performance of a mature commercial fruit-bearing 'Hass' avocado orchard (Persea americana Mill.) growing in a clay soil irrigated with TWW since 2009. The mitigation measures, each in 6 replicates, included freshwater
