Irrigation and fertilization stress in plants are limitations for securing global food production. Sustainable agriculture is at the heart of global goals because threats of a rapidly growing population and climate changes are affecting agricultural productivity. Plant phenotyping is defined as evaluating plant traits. Traditionally, this measurement is performed manually but with advanced technology and analysis, these traits can be observed automatically and nondestructively. A high correlation between plant traits, growth, biomass, and final yield has been found. From the early stages of plant development, lack of irrigation and fertilization directly influence developing stages, thus the final crop yield is significantly reduced. In order to evaluate drought and fertilization stress, plant height, as a morphological trait, is the most common one used in precision-agriculture research. The present study shows that three-dimension volumetric approaches are more representative markers for alerting growers to the early stages of stress in young banana plants' for fine-scale phenotyping. This research demonstrates two different group conditions: 1) Normal conditions; and 2) zero irrigation and zero fertilization. The statistical analysis results show a successfully distinguished early stress with the volumetric traits providing new insights on identifying the key phenotypes and growth stages influenced by drought stress.

冠层体积作为早期发现植物干旱和施肥胁迫的工具：香蕉植物细表型

植物的灌溉和施肥压力是确保全球粮食生产的限制。可持续农业是全球目标的核心，因为人口快速增长和气候变化的威胁正在影响农业生产力。植物表型被定义为评估植物性状。传统上，该测量是手动执行的，但是借助先进的技术和分析，可以自动无损地观察这些特征。已经发现植物性状，生长，生物量和最终产量之间具有高度相关性。从植物发育的早期阶段开始，缺乏灌溉和施肥会直接影响发育阶段，因此最终作物的产量会大大降低。为了评估干旱和施肥压力，将株高作为一种形态特征，是精密农业研究中最常用的一种。本研究表明，三维体积方法是更具代表性的标记，可以提醒种植者警惕年轻香蕉植物的早期胁迫，以进行精细的表型分析。这项研究证明了两种不同的群体条件：1）正常条件；2）零灌溉和零施肥。统计分析结果显示，成功的早期胁迫具有明显的体积特征，为识别受干旱胁迫影响的关键表型和生长阶段提供了新的见识。这项研究证明了两种不同的群体条件：1）正常条件；2）零灌溉和零施肥。统计分析结果显示，成功的早期胁迫具有明显的体积特征，为识别受干旱胁迫影响的关键表型和生长阶段提供了新的见识。这项研究证明了两种不同的群体条件：1）正常条件；2）零灌溉和零施肥。统计分析结果显示，成功的早期胁迫具有明显的体积特征，为识别受干旱胁迫影响的关键表型和生长阶段提供了新的见识。
