The production of fruit crops plays a vital role in the agricultural sector, contributing significantly to social and economic development rural communities. In Brazil, is diverse due favorable edaphoclimatic conditions, with avocado (Persea americana Mill.) emerging as an important crop. Its continues expand both cultivated areas yield, making it key export non-producing countries. However, despite its importance, nutritional management information, crucial for achieving high yields, remains limited. Current guidelines on nutrition monitoring are outdated, general, based data from other countries different them not directly applicable Brazilian orchards. Furthermore, outdated information becomes less reliable over time, climate change alters soil conditions crop nutrient concentrations requirements, reinforcing need establishment up-to-date specific information. This study aimed establish standards ‘Hass’ using Diagnosis Recommendation Integrated System (DRIS) Compositional Nutrient (CND) methodologies, define sufficiency ranges (SRs) Critical Levels (CLs) macronutrients (N, P, K, Ca, Mg, S) micronutrients (B, Cu, Fe, Mn, Zn). analyses were yield (t ha−1) leaf content commercial orchards, datasets divided into younger (4–9 years) older (10–26 plant groups. DRIS effectively established plants, explaining 11% variation through balance. CND, turn, was effective groups, accounting 14% outperforming associating status productivity. SRs CLs defined CND. Together, these indices diagnostic parameters offer valuable tools enhancing fertilization strategies Brazil. Notably, varied according age.

The relationship between plants and their environment has always been a core issue in ecological research. This study about how plant architecture leaf traits respond to environmental changes helps more deeply understand the adaptive mechanisms of diverse environments. Although there have related studies, systematic analysis on China-wide scale is still lacking. To address this gap, we conducted meta-analysis 115 studies across China examining architectural trait responses changes. dataset includes 849 observations 11 variables, such as mean annual precipitation, temperature, soil type, elevation, evaluates effects seven key traits. results indicated that variations height, diameter at breast height (DBH), root-to-shoot ratio are primarily influenced by type precipitation. In contrast, sunshine duration mainly affected specific area (SLA), area, thickness, dry matter content. Moreover, while magnitude varies property gradients, impacts change particularly pronounced under extreme conditions. provides robust scientific evidence for understanding growth offers valuable insights into conservation sustainable use resources.
