Adapting soybean varieties to soil fertility variability for increased productivity in smallholder systems of Uganda
Abstract

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.
