Abstract

144 words

Biophysical conditions; climate and soil types underpin the suitability for growing of different crops at larger scales such as the agroecological regions while at the lower scales, crop production is governed by soil fertility status and management. These factors together with and socio-economic environment (e.g. culture, markets, infrastructure etc.) create niches for production of a given crop. This research aims at identifying niches for sustainable production of soyabean and will test the hypothesis that suitability of different soyabean varieties differ between and within agroecological zones. The research will be conducted in the Southern and Eastern Lake Kyoga basin and Northern tall grasslands agroecological zones and will involve active farmer collaboration. Participatory variety selection will complement agronomic experimentation to identify best fitting soyabean varieties within the agroecological zones. Appropriate soil fertility management practices necessary for high productivity of the soyabean varieties will also be developed.
