A data-driven evaluation of chitosan, clybio and Paraburkholderia synergy for improving yield and biochemical traits of onion (Allium sepa L.)

In the subtropics, onions face challenges of optimum production and quality due to adverse climate fluctuations and imbalanced agronomic practices. This data file describes the impact of integrated foliar application of chitosan, clybio and Paraburkholderia fungorum on plant growth, bulb yield, biochemical properties and functional attributes in onion under fluctuating subtropical weather conditions. Chitosan (100 and 200 ppm), clybio (a yeast and Bacillus blend at 0.5%) and Paraburkholderia fungorum BRRh-4 (1.5 × 10^9 CFU/mL) were applied eleven combinations plus a control (no bio-agents) following a randomized complete block design with three replications. Data were recorded on 21 parameters related to vegetative, reproductive, biochemical, nutritional and mineral properties of onion. Further, statistical analysis and graphical representation confirmed the superior treatment for improving yield and quality of onion under such challenging environments.在亚热带区域，受不利气候波动与不均衡农艺措施的影响，洋葱在实现最优生产与品质保障方面面临诸多挑战。本数据集详述了在亚热带波动气候条件下，壳聚糖（chitosan）、clybio（0.5%酵母与芽孢杆菌复配制剂）以及真菌伯克霍尔德菌（Paraburkholderia fungorum）的集成叶面施用方案，对洋葱植株生长、鳞茎产量、生化特性与功能属性的调控效应。试验共设置11种施用组合及1个对照组（不施用生物制剂）：其中壳聚糖设置100 ppm与200 ppm两个浓度梯度，clybio为0.5%酵母与芽孢杆菌复配制剂，真菌伯克霍尔德菌BRRh-4（Paraburkholderia fungorum BRRh-4）的施用浓度为1.5×10^9 CFU/mL；试验采用随机完全区组设计，设置三次生物学重复。研究采集了与洋葱营养生长、生殖生长、生化特性、营养成分及矿质元素相关的共计21项指标数据。此外，通过统计分析与可视化图表验证，在该挑战性环境中，存在可显著提升洋葱产量与品质的最优处理方案。
