Urban Farm DB summary
This experimental study evaluated the effects of chicken and goat manure (five application levels) on lettuce growth and yield under urban organic farming conditions. Goat manure significantly (p < 0.01) enhanced all growth and yield parameters compared with chicken manure, which had no significant effect due to its high C/N ratio and immature composition. Optimal performance was observed at 30–40 tons ha⁻¹ of goat manure, with 30 tons ha⁻¹ identified as the most efficient rate.
