The long-term sustainability of cotton-based systems is at risk in the Nigerian savanna because of its environmental effects. Presently, policies aimed at addressing the problems of soil fertility decline and insecticide contamination are being advanced. The effects of two organic materials (i.e. cowdung and poultry litter) as soil amendments and, two others (extracts of garlic and west African black pepper) as insecticidal materials on soil physical properties and upland cotton (Gossypium hirsutum L.) productivity were compared with the conventional method (mineral fertiliser and synthetic insecticide) in a 2 year field trial on a savanna Alfisols. Seed cotton yield under mineral fertiliser amendment was about 30% higher than were yields from the two organic amendments. However, the cotton lint yield from the three amendments were similar. Seed cotton, cotton seed and lint yields were similar for cotton that received garlic extract and karate (synthetic insecticide). Cotton sprayed with extract of west African black pepper produced significantly higher seed cotton and cotton lint yield than the synthetic insecticide. The treatments had no significant effect on soil physical properties. This result further confirms the usefulness of organic cotton cultivation, a viable alternative to the conventional method of cotton production in the savanna. |
