Other claims from this paper (9)
- Intervention effect The highest energy incorporation of Jatropha, 37.48 GJ ha-1, was in N150 under irrigation.
- Observation Without counting residues, only N150 under irrigation was energetically efficient, with EROI of 1.04.
- Observation Considering residues, EROI of N150 with irrigation was 1.15.
- Observation Considering residues, EROI of N100 with irrigation was 1.06.
- Intervention effect Irrigation increased EROI by 63% at the N100 fertilization level.
- Intervention effect Irrigation increased EROI by 34% at the N50 fertilization level.
- Intervention effect Irrigation increased EROI by 203% at the N0 fertilization level.
- Association Nitrogen applied together with irrigation resulted in higher fruit yield and input energy despite greater energy investment.
- Observation Fuels were the energy input component that contributed most to Jatropha production, 17.71 GJ ha-1 across all conditions.
