Water savings, nutrient leaching, and fruit yield in a young avocado orchard as affected by irrigation and nutrient management'

Authors: Kiggundu, N.; Migliaccio, K.; Schaffer, B.; Li, Y.; Crane, J.

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

An irrigation schedule testing model for optimization of the Smartirrigation avocado app

Authors: Mbabazi, D.; Migliaccio, K.; Crane, J.; Fraisse, C.; Zotarelli, L.; Morgan, K.; Kiggundu, N.

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
