On Farm Participatory Evaluation and Demonstration of Vertisol Management Structures under Mechanized Farm in Adaba District, Southeastern Ethiopia

The field experiment was conducted in 2015-2017 for two consecutive years to investigate the effects of different drainage systems on yield of bread wheat on the waterlogged Vertisols. The demonstration of this research was conducted with Mechanized farm at Hunte Oromia seed enterprise farm. The raised camber bed and flatbed was evaluated using Bread wheat as test crop. Camber beds were formed to make a raised profile of 4.8 m wide and 0.3 cm high from the furrow to the top of the bed and the flat bed was carried out with tractor drawn machine. The result revealed that bread wheat grown on improved drainage techniques under camber bed had better yield advantage as compared to farmers’ practices (Flatbed). The highest biomass yield of 8 t ha-1which is 60% higher over the farmers practice (flatbed) was recorded and the highest grain yield of 6.2 t ha-1 which is 55% higher over the famers’ practice was obtained. In addition, farmers preference toward the technology was indicated that camber bed vertisol drainage system was selected on the bases of its yield advantage and their performance. Therefore, Camber bed land drainage technologies was recommended for further scaling up in mitigating drainage problem in Vertisol and reduce waterlogging at Adaba district and similar condition for production of bread wheat.
