Other claims from this paper (19)
- Intervention effect First-year Manure-start produced 3.4 t ha −1 of maize grain.
- Intervention effect First-year Litter-start produced 2.5 t ha −1 of maize grain.
- Intervention effect First-year Manure-start produced 12 × 10 6 kcal, 50% more than Litter-start and Fertilizer-start.
- Intervention effect Soya-start had the highest protein production at 720 kg, versus under 450 kg for other sequences.
- Observation Second-year sequences averaged 5.7 t ha −1 maize grain.
- Observation Second-year sequences produced over 19 × 10 6 kcal.
- Observation Second-year sequences produced 400 kg protein.
- Intervention effect Second-year sequences significantly outperformed poor fields by about fivefold.
- Intervention effect Third-year Soya-start gave the highest maize yield at 3.7 t ha −1.
- Intervention effect Third-year Soya-start produced three times more calories than poor fields.
- Intervention effect Fourth-year Fertilizer-start produced the highest calories at 14 × 10 6 kcal.
- Intervention effect Fourth-year Fertilizer-start produced the highest protein at 340 kg.
- Intervention effect Across four years, Manure-start and Soya-start had the highest calories and protein, exceeding rich and poor fields.
- Intervention effect Green-start and Fertilizer-start increased plant-available soil phosphorus by about 4 mg kg −1 over four years.
- Intervention effect Fertility sequences had significantly greater P agronomic efficiency than rich and poor fields.
- Observation Soya-start had the best four-year net present value.
- Observation Fertilizer-start was the least financially attractive sequence.
- Intervention effect ISFM sequences were more profitable than farmer-designated rich and poor fields.
- Recommendation The authors conclude ISFM sequences offer farm-level intensification options for Southern African smallholders.
