Varieties for Phonological, Growth and Yield Characters. Current Research in Agricultural Sciences, 3(2): 22-30. DOI: 10.18488/journal.68/2016.3.2/188.8.131.52
The field experiment was carried out at the research station of Mehoni Agricultural Research Center, Fachagama, Ethiopia in 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.
The paper`s primary contribution is finding that to study the agronomic evaluation of tomato (Lycopersicon esculentum, Mill) varieties for phonological, growth and yield related characters. In that case it provides tangible information and addresses the issues of best adaptable varieties to the specific agro-ecology for tomato growers.

Onion (Allium cepa L.) is the most common member of the family Amaryllidaceae (Alliaceae) which grows as a herbaceous biennial vegetable crop with cross pollinated and monocotyledonous behavior having diploid chromosomes number 2n=16. In order to identify Genotypic difference in growth, yield and yield related traits of Onion varieties, the field experiment was carried out at the research station of Mehoni Agricultural Research Center, southern, Ethiopia in the 2013 and 2014 cropping season under irrigation condition. The experiment was consisted of varieties of onion arranged in completely randomized block design with four replications. In 2013 cropping season, days to 50% maturity, bulb diameter and unmarketable were significantly affected by varietal difference. On the other hand, marketable yield, unmarketable yield and total yield were also influenced through varietal effect in 2014. The highest marketable yield (318.52 q ha-1) was obtained from Adama red variety; which, however, it was statistically on par with the marketable yield (289.26 q ha-1) at Nafis variety whereas the lowest marketable yield (222.41 q ha-1) was recorded at Nasik red variety in 2014 cropping season.
The paper`s primary contribution is finding that to study genotypic difference in growth and yield related traits of onion (Allium cepa L.) varieties at southern Tigray, Ethiopia. Then, it provides concrete information on the best adaptable varieties to the specific agro-ecology for onion growers particularly in the specific study area.
