- Intervention effect Nitrogen rate significantly (P ≤ 0.001) influenced lettuce plant height, number of leaves per plant and leaf width.
- Intervention effect Phosphorus rate significantly (P ≤ 0.001) influenced lettuce plant height, number of leaves per plant and leaf width.
- Intervention effect Lettuce leaf length was not affected by phosphorus rates.
- Intervention effect The interaction of nitrogen and phosphorus rates significantly (P ≤ 0.001) influenced days to maturity of lettuce.
- Intervention effect The interaction of nitrogen and phosphorus rates significantly (P ≤ 0.001) influenced fresh leaf weight per plant, marketable fresh leaf yield and total fresh leaf yield of lettuce.
- Intervention effect The highest net benefit of 241,070 ETB per ha was achieved with 138 kg N per ha plus 92 kg P2O5 per ha.
- Recommendation The combination of 138 kg N and 92 kg P2O5 per ha is economically optimal and can be recommended for lettuce production in the study area.
