Evaluation activity was conducted using four sweet potato varieties (Awassa-83, Kabode, Kulfo and Tulla) at Mehoni Agricultural Research Center (MeARC) during 2015 and 2016 testing years. The treatments were arranged in randomized complete block design with three replications. The analysis of variance table indicated the existence of significant variation among sweet potato varieties for all the characters considered in this study in both 2015 and 2016 testing years except number of nodes/plant and tuber diameter during 2016 cropping year. From this investigation, significantly higher marketable yield (29.20 t ha-1) and total yield (33.42 t ha-1) were obtained from Kulfo variety. Overall, Kulfo was found well adapted and produced higher yield in the testing location. Hence, it is possible to use Kulfo variety for the production of marketable and total tuber yield by farmers and investors in Raya Azebo, Ethiopia.

Onion (Allium cepa L.) is the most common member of the family

2013 and 2014 cropping season under irrigation and in 2014 for rain fed experiment only. The experiment consisted of four commercial tomato varieties arranged in a completely randomized block design with four replications. In the 2013 cropping season, days to 50% flowering and maturity, plant height, fruit length, fruit diameter, number of fruits per plant, marketable yield, unmarketable yield and total yield were significantly influenced by varietal difference. Likewise, it was also observed that variety exerted a significance effect on establishment percentage, days to 50% maturity, plant height, number of fruits/plant and marketable yield under both irrigation and rain fed and on unmarketable yield under irrigation conditions of the 2014 cropping year. Under irrigation, the highest marketable yield (414.58 q ha-1) was obtained at Chali variety followed by Miya variety (289.17 q ha-1) in 2014 while the lowest value (110.83 q ha-1) was obtained from Melka sholla in the 2013 cropping season. Whereas the highest (295.58 q ha-1) and lowest marketable yields (283.33 q ha-1) were observed at Chali and Melksa sholla varieties under rain fed condition of the 2014 cropping season.
