Other claims from this paper (16)
- Intervention effect Intercropped sweet potato had longer vines and more leaves than sole sweet potato.
- Intervention effect NPK did not significantly affect vine length or branch number in either system.
- Intervention effect The abstract also reports more vine branches under sole cropping than intercropping for all fertiliser treatments.
- Intervention effect NPK significantly affected sweet potato leaf number in sole cropping.
- Intervention effect Fertilised sole sweet potato had more leaves than the unfertilised control.
- Observation NASPOT 11 had the highest tuber yield in both systems.
- Observation NASPOT 8 ranked second for tuber yield in both systems.
- Intervention effect Sole sweet potato yielded 43.36 MT/ha versus 33.35 MT/ha intercropped.
- Intervention effect Sole maize had greater grain yield than intercropped maize.
- Intervention effect Fertilised intercrops had greater maize grain yields than corresponding controls.
- Observation All intercrops had land equivalent ratios above one.
- Intervention effect The authors conclude 120-60-90 kg/ha N-P-K improves intercropped tuber yield against no fertiliser.
- Intervention effect Above 40-20-30 kg/ha N-P-K, intercropped and sole tuber yields did not significantly differ.
- Mechanism The authors infer fertiliser eliminates interspecific nutrient competition in intercrops.
- Observation The authors infer sweet potato cultivars and hybrid maize are compatible for intercropping.
- Recommendation The authors recommend intercropping improved sweet potato with hybrid maize and 120-60-90 kg/ha NPK.
