Baby Spinach Treated-and-Control Comparison
The trial layout
The record describes a 13-bed comparison using the same baby-spinach cultivar across approximately 1.3 acres. Twelve beds received treated irrigation water and one foliar application. The thirteenth bed remained untreated as the control. The source estimated approximately four million plants per acre.
Application and monitoring
- The irrigation application was recorded at the historical concentration specified in the field report.
- A foliar application was recorded on August 2, 2014.
- The grower and field personnel monitored germination, cotyledons, first-leaf development, pre-harvest leaf size, plant condition and harvest weight.
- Client staff recorded harvest weights; application work and field observations were identified in the source record.
Recorded results
| Harvest | The source report states that the treated beds produced a 9.2% greater harvest weight than the untreated bed. |
| Leaf size | Before harvest, the report classified about 70% of control-bed leaves as under 1.25 inches in diameter and about 70% of treated-bed leaves as over 1.75 inches. |
| Plant condition | Field personnel recorded differences in cotyledon shape, leaf turgidity and first-leaf appearance. |
| Disease observations | The report states that specified diseases were not observed in the treated beds; this observation does not prove prevention or treatment efficacy. |
What this case teaches
The comparison provides a documented commercial-field observation with a harvest measurement and contemporaneous photographs. Interpretation must account for the unequal number of treated and control beds, the single production cycle and the combined irrigation-plus-foliar protocol.
Evidence classification
Classification: Commercial-field comparison with one untreated control bed, recorded harvest weights and photographic observations. Not peer reviewed.
Important notice
The result applies only to the recorded crop, site, season and protocol. Puroxi does not guarantee yield, disease control or crop response. Current agricultural use requires water analysis, crop-specific review, label compliance and a controlled evaluation.
