This study examined how using zinc oxide, time, and place of planting influence important biochemical and physiological characteristics that affect crop yield. Zinc is an essential micronutrient that increases enzyme activity, regulates plant hormones, and enhances stress tolerance under varying environmental conditions, so it is important to supplement with zinc. The results of the study found that the optimum planting time (October), seed yield is highest with moderate zinc oxide levels (2.5 ppm) and structural growth characteristics such as the number of nodes and pods per plant, etc. On the other hand, zinc oxide concentration is higher (5 ppm), improving various characteristics such as root length and plant height, and the growing situation at the end of the period demonstrates efficiency. Although this will have a limited impact on overall productivity. Hierarchical clustering and principal component analysis revealed different efficacy patterns between treatments. Highlighting the important interactions between nutrient management, planting time, and location, correlation analysis revealed strong relationships between seed yield and traits such as site germination rate and number of nodes. This emphasizes the physiological interdependence that drives productivity. These findings provide practical insights into optimizing zinc oxide use and planting strategies to increase plant growth and resilience under various conditions.
本研究考察了使用氧化锌、种植时间和种植地点如何影响影响作物产量的重要生化和生理特性。锌是一种必需的微量营养素，它能增加酶活性、调节植物激素并增强在不同环境条件下的胁迫耐受性，因此补充锌很重要。研究结果发现，最佳种植时间（10月），中等氧化锌水平（2.5 ppm）时种子产量最高，且植株的节点数和荚果数等结构生长特性最佳。另一方面，氧化锌浓度较高（5 ppm）时，根长和株高等各种特性得到改善，且该时期末的生长状况显示出有效性。尽管这对总体生产力的影响有限。层次聚类和主成分分析揭示了不同处理之间的不同功效模式。相关性分析突出了养分管理、种植时间和地点之间的重要相互作用，揭示了种子产量与诸如位点发芽率和节点数等性状之间的强关系。这强调了驱动生产力的生理相互依存关系。这些发现为优化氧化锌使用和种植策略以在各种条件下提高植物生长和恢复力提供了实际见解。
