However, validation of the SEBAL using in-field direct and indirect measurements of plant water status is a necessary step before deploying the algorithm as an irrigation scheduling tool. To this end, a study was conducted in a maize field located near the Venice Lagoon area in Italy. The experimental area was irrigated using a 274 m long variable rate irrigation (VRI) system with 25-m sections. Three irrigation management zones (IMZs; high, medium and low irrigation requirement zones) were defined combining soil texture and normalized difference vegetation index (NDVI) data. Soil moisture sensors were installed in the different IMZs and used to schedule irrigation. In addition, SEBAL-based actual evapotranspiration (ETr) and biomass estimates were calculated throughout the season. VRI management allowed crop water demand to be matched, saving up to 42 mm (\u221216%) of water when compared to uniform irrigation rates. The high irrigation amounts applied during the growing season to avoid water stress resulted in no significant differences among the IMZs. SEBAL-based biomass estimates agreed with in-season measurements at 72, 105 and 112 days after planting (DAP; r2 = 0.87). Seasonal ET matched the spatial variability observed in the measured yield map at harvest. Moreover, the SEBAL-derived yield map largely agreed with the measured yield map with relative errors of 0.3% among the IMZs and of 1% (0.21 t ha\u22121) for the whole field. While the FAO method-based stress coefficient (Ks) never dropped below the optimum condition (Ks = 1) for all the IMZs and the uniform zone, SEBAL Ks was sensitive to changes in water status and remained below 1 during most of the growing season. Using SEBAL to capture the daily spatial variation in crop water needs and growth would enable the definition of transient, dynamic IMZs. This allows farmers to apply proper irrigation amounts increasing water use efficiency.<\/jats:p>","DOI":"10.3390\/rs11172069","type":"journal-article","created":{"date-parts":[[2019,9,4]],"date-time":"2019-09-04T08:28:13Z","timestamp":1567585693000},"page":"2069","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Integrating SEBAL with in-Field Crop Water Status Measurement for Precision Irrigation Applications\u2014A Case Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Stefano","family":"Gobbo","sequence":"first","affiliation":[{"name":"Department of Agronomy, Food, Natural resources, Animals and Environment (DAFNAE), Universit\u00e0 degli Studi di Padova, 35020 Legnaro, Italy"}]},{"given":"Stefano","family":"Lo Presti","sequence":"additional","affiliation":[{"name":"Centrale Valutativa Srl, 00131 Roma, Italy"}]},{"given":"Marco","family":"Martello","sequence":"additional","affiliation":[{"name":"Department of Agronomy, Food, Natural resources, Animals and Environment (DAFNAE), Universit\u00e0 degli Studi di Padova, 35020 Legnaro, Italy"}]},{"given":"Lorenza","family":"Panunzi","sequence":"additional","affiliation":[{"name":"Centrale Valutativa Srl, 00131 Roma, Italy"}]},{"given":"Antonio","family":"Berti","sequence":"additional","affiliation":[{"name":"Department of Agronomy, Food, Natural resources, Animals and Environment (DAFNAE), Universit\u00e0 degli Studi di Padova, 35020 Legnaro, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9081-868X","authenticated-orcid":false,"given":"Francesco","family":"Morari","sequence":"additional","affiliation":[{"name":"Department of Agronomy, Food, Natural resources, Animals and Environment (DAFNAE), Universit\u00e0 degli Studi di Padova, 35020 Legnaro, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1007\/s00271-007-0063-2","article-title":"A systematic and quantitative approach to improve water use efficiency in agriculture","volume":"25","author":"Hsiao","year":"2007","journal-title":"Irrig.
