Impact of integrated soil fertility management practices on maize yield in Ethiopia

Popis výsledku v původním jazyce

Today, declining soil fertility is the main biophysical constraint to improve crop yield and poses a potential threat to food security. This study aims to explore the elements that could influence the adoption of integrated soil fertility management (ISFM) practices as well as their impact on maize yield. This study is based on a pseudopanel collected by Ethiopia's central statistical agency (CSA) in collaboration with the World Bank. A Multinomial Endogenous Switching Regression model (MESR) was employed to achieve the specified objectives. The findings revealed that 15% of plots received no soil fertility-enhancing treatments, while 35% received a combination of inorganic fertilizer and manure to boost soil fertility. The average maize yield in the study was 3.44 tons per hectare, which was nearly equal to the average national yield in the prior year. Finally, maize yield was significantly influenced by soil fertility management measures, whether used alone or in combination of two or more soil fertility enhancing technologies. The extent of the impact, however, varies significantly depending on the inputs employed. Thus, using manure or compost alone had a moderate but significant impact on maize yield, but using inorganic fertilizer in combination with manure had the biggest impact. Therefore, policies that support the expansion of ISFM practices should be promoted. Farm households also receive technical assistance and training to better understand the use of ISFM practices, and policies that promote them should be expanded.
