The increasing demand for fresh water from production sectors of major socioeconomic importance means there is a greater need to optimize water use in agriculture. Therefore, this project aims to use deficit irrigation strategies in Japanese plum and vine, in order to achieve greater control over excessive vegetative growth without negative effects on production yields; improved fruit quality at harvest and postharvest quality; and the identification and segmentation of plots according to the production objectives farmers wish to achieve.

Task 2. Use of precision agriculture to optimize water and fertilizer use and harvest date in vineyards

This project aims to study spatial and temporal variability in vineyards in order to identify distinct areas for the use production factors (fertilizers, irrigation, pesticides, etc.) to enable a more efficient use of factors and increase productivity and uniformity of production. In order to do this, soil electrical conductivity will be measured, vegetation indices (NDVI) determined and yield maps produced in two vineyards in Évora and Badajoz.

The information obtained will be analysed to define differentiated areas and implementation strategies. The quality of wines produced with grapes from different areas of the vineyard in Évora will also be analysed, in order to study the influence of the spatial variability of the soil on the quality of the wine and define areas of differentiated harvesting.
