Current water scarcity scenario has led to the implementation of sustainable agricultural practices intended to improve water use efficiency. The present work evaluates during three agricultural campaigns (2018–2020) the response of a young almond orchard to two management practices in terms by combining remote sensing indexes (Normalized Difference Vegetation Index, NDVI; and Soil Adjusted Vegetation Indexes, SAVI) and physiological/morphological measurement (stem water potential, Ψ_stem; trunk perimeter and canopy diameter). The management practices included (i) sustained deficit irrigation and (ii) soil management. Severe deficit irrigation resulted in lower vegetation indexes (VI) values, Ψ_stem and tree dimensions (13 %, 23 % and 14 % lower, respectively) than those obtained for full irrigation strategy; whereas moderate deficit irrigation did not affect any of the parameters analysed. The presence of vegetation cover in the inter-row resulted in a VI_s increase (19–42 %) and in lower tree dimensions (reductions of 7–8 % for trunk perimeter and 0.34–0.37 m for canopy diameter) when compared to bare soil treatment, but did not have any influence on Ψ_stem. The present study proves the suitability of remote sensing and physiological measurements for assessing almond response to the different management practices.

当前的水资源短缺情况导致实施旨在提高用水效率的可持续农业实践。目前的工作通过结合遥感指数（归一化差异植被指数，NDVI；和土壤调整植被指数，SAVI）和生理/形态测量（茎水势，Ψ_茎；树干周长和冠层直径）。管理实践包括 (i) 持续亏缺灌溉和 (ii) 土壤管理。严重的亏缺灌溉导致植被指数 (VI) 值降低，Ψ _stem和树木尺寸（分别低 13%、23% 和 14%）比完全灌溉策略获得的尺寸；而适度的亏缺灌溉不影响任何分析的参数。与裸露相比，行间植被覆盖的存在导致 VI _s增加（19-42%）和较低的树木尺寸（树干周长减少 7-8%，树冠直径减少 0.34-0.37 m）土壤处理，但对Ψ_茎没有任何影响。本研究证明了遥感和生理测量对评估杏仁对不同管理实践的反应的适用性。
