Other claims from this paper (11)
- Intervention effect Conventional tillage (Con) increased grain yields of maize and cowpea compared with hand hoe and zero tillage
- Intervention effect Bullock plough (BP) with tillage depths over 12 cm increased grain yields of both crops compared with hand hoe and zero tillage
- Intervention effect Conventional tillage (Con) reduced weed score, weed count and weed dry matter compared with hand hoe and zero tillage
- Intervention effect Bullock plough (BP) reduced weed score, weed count and weed dry matter compared with hand hoe and zero tillage
- Intervention effect Tillage systems did not influence the weed flora
- Intervention effect Cropping systems increased grass composition in maize to about 70 per cent
- Intervention effect Zero tillage (ZT) incurred the highest cost of production
- Intervention effect Bullock plough (BP) gave the highest net benefits and benefit-cost ratio
- Intervention effect The maize component had higher BCRs in intercrops than in sole cropping
- Association Poor rainfall distribution had a negative impact on the yield of both crops
- Association Inter-row cropping systems gave negative BCRs in both years
