Summary
This greenhouse study evaluated foliar applications of legume-derived protein hydrolysate on two tomato cultivars, measuring dose-dependent responses in plant growth, leaf mineral nutrient content, marketable yield and fruit quality attributes. The findings suggest that bioactive plant-derived biostimulants may enhance horticultural productivity and nutritional composition in protected tomato production systems.
Regional applicability
Findings are applicable to United Kingdom glasshouse tomato production, particularly commercial protected cultivation systems. Results would likely translate to UK greenhouse conditions, though performance may vary with local cultivars, growing media and greenhouse climate management practices.
Key measures
Plant growth metrics, leaf mineral composition, fruit yield, fruit quality parameters
Outcomes reported
The study measured growth parameters, leaf mineral composition, yield and fruit quality in greenhouse tomato cultivars following foliar application of legume-derived protein hydrolysate at varying doses.
