| description | Agroecology has been highlighted as a sustainable approach with the potential to support food system transformation in both low and middle-income countries. Its potential to improve soil and crop productivity is unmatched. Implementation of innovative agroecology practices is key in promoting soil quality and health, improving agrobiodiversity and enhancing crop productivity.
We assessed the influences of select agroecology practices on maize and bean crop performance in nutrient deficient sandy soils in Makueni County, Kenya. The study was conducted on 30 resource-constrained smallholder farms during the short rains season of the year 2023. The innovative agroecology practices tested involved; i) use of biopesticides (IPM); ii) terracing, and iii) use of organic inputs (manure). The three agroecology practices geared towards pest (IPM), water (terraces) and soil (manure) management. We present the results of one cropping season.
Preliminary results show that agroecological practices involving combined use of biopesticides and organic inputs increased maize and bean yields relative to the rest of the practices. Across the three agroecology practices implemented, maize yields increased by at least 40 kilograms. Relative to control plots, maize yields increased by 109, 78 and 40 kilograms per acre respectively under terraces, manure and IPM practices, respectively. This was consistent to monetary gains averaging USD$ 50.26, 63.14 and 18.28 per acre in one season under terraces, manure and IPM, respectively. Similarly, increased by 20.7, 33.3 and 19.8 kilograms per acre per season, respectively under IPM, Manure and terraces. These were equivalent to monetary gains of USD$ 25.48, 40.98 and 24.37, respectively under IPM, manure and terraces.
These results provide preliminary evidence to support the promotion of agroecological practices among farmers and policy makers. In addition, the outcomes indicate that agroecological practices are effective in boosting crop performance, underpinning the possibility to attain improved productivity and sustainability through integration of agroecology practices. Finally, farmers can effectively and cheaply manage crop pests through the use of biopesticides that reduces dependence on harmful and expensive chemical pesticides. |
