Other claims from this paper (18)
- Intervention effect Intercropping with cassava had no significant effect on okra phenology (time to vegetative growth, flowering and fruiting).
- Intervention effect Intercropping significantly reduced weed growth by 25-45% compared with monoculture.
- Intervention effect Intercropping significantly reduced nematode infection in okra by 36% compared with monoculture.
- Intervention effect Intercropping kept the canopy environment of cassava cooler by 3.0-4.4 degrees C compared with monoculture.
- Association The durations of vegetative and reproductive growth of okra in both cropping systems were influenced by population density.
- Association The weed-control ability of okra in both cropping systems was influenced by population density.
- Intervention effect Okra sown at 50000 plants/ha took the longest time to reach specific phenological stages.
- Intervention effect Okra sown at 50000 plants/ha controlled weeds best.
- Intervention effect Okra sown at 50000 plants/ha gave the highest fresh pod yields in both seasons.
- Intervention effect There was little increase in okra pod yields between 35000 and 50000 plants/ha in mixed stands in late season sown crops.
- Intervention effect Cassava growth and tuber yield were not significantly affected by intercropping and okra population density.
- Intervention effect Okra growth was better with early than late season sowing, irrespective of okra population density or cropping system.
- Intervention effect Cassava growth was better with early than late season sowing, irrespective of okra population density or cropping system.
- Mechanism The better growth of okra with early sowing appears to be due mainly to temperature and rainfall differences between the seasons.
- Mechanism The better growth of cassava with early sowing appears to be due mainly to temperature and rainfall differences between the seasons.
- Association The substantial variation in weather between the two seasons had a greater effect in monoculture than in mixed stands.
- Recommendation When rainfall is limiting, okra could be intercropped with cassava at population density up to 35000 plants/ha to allow the vegetable to develop and to maximize pod yield under relatively dry conditions.
- Recommendation The suggested optimum okra target is 50000-60000 plants/ha during the wet periods.
