Effects of organic amendment based on biodigester effluent on cotton yield parameters in the Cascades region of Burkina Faso
- International Journal of Biosciences (IJB) , 27 (4) : 1-7
Résumé
The present study aimed to explore the effectiveness of compost produced from biodigester effluent on the agronomic parameters of cotton in the Cascades region of Burkina Faso. To this end, the fertilizing value of composts produced from biodigester effluent was characterized. The effect of the compost on cotton yield parameters was evaluated using an experimental setup. The on-farm experiment was based on a Completely Randomized Block Design with six replications. Each block included five treatments: one exclusively mineral treatment, two treatments using compost alone, and two treatments combining compost and mineral fertilizers. In addition, the average weight of cottonseed per plant and the cottonseed yield were determined. The results showed relatively average contents of organic matter (20.95%), total phosphorus (0.30 g/kg), and total nitrogen
(0.66%), as well as low levels of total potassium (0.62 g/kg) compared to FAO standards. Fertilization combining 5 t/ha of compost + 200 kg/ha of NPK was the one that produced the best results on the evaluated cotton yield parameters. The production of compost from biodigester effluent is a way to valorize household waste, plant debris, and animal manure to improve cotton yields while restoring soil fertility.
