The principal crops grown are teff, sorghum, barley, wheat, and lentils.
Moreover, at the initial period, yields for teff, beans, and barley declined by 51, 23, and 14.5 kg per cm of eroded soil, respectively.
Coupled with higher rates of soil erosion and higher crop responses to soil depth, conservation is more attractive for teff and beans than barley.
The yearly average main season area covered by teff is about 1.91 million ha making up 29 % of the total cereal area.
There were no significant differences in teff among all of the conditions.
Under barley and beans, soil depth declines more slowly compared to teff (table 4).
Despite this, the total straw portion of the intercrop was less than that of sole teff.
The teff determined for the brightest intensity was used for subsequent lower intensities.
