Shallot (Allium cepa var. ascalonicum Backer) is an important vegetable crop cultivated by small holder farmers for consumption in Gamo mid and high lands. However, its production and productivity is constrained by lack of improved shallot varieties in the study area. Field experiment was conducted in Gamo Zone during 2021 and 2022 cropping season. The objective of the experiment was to select well adaptive and high yielding shallot varieties for the study areas. Eight shallot varieties in two sets (bulb propagated sets and seed propagated sets) were evaluated in randomized complete block design with four replications by using double row spacing of 40cm x 20cm in Plot size of 2.4m x 2m. The combined analysis of the mean over years showed that there was a statistical significant mean difference (P<0.01) among the varieties for yield and some yield related traits. Among the bulb propagated varieties tested, the highest number of splits (13.75) per plant (bulb) was recorded by variety ‘’DZSHT-00/2” followed by “Minjar” (12.18). Similarly, “DZSHT-00/2” gave the highest bulb yield (21.22 t ha-1) followed by “Minjar” (19.27 t ha-1). On the other hand, the highest marketable bulb yield of 9.61 t ha-1 was recorded by variety “Tropics” followed by “DZSHT-157-21” (7.47 t ha-1). Hence, varieties “DZSHT-005/2” and “Tropics” are recommended for popularization and production due to their better yield and adaptability in the study area.

This research is an initial study of the effects of vernalization and Gibberellins in two different environments. The research was conducted in a split-split plot design with three factors and three times repetition. The main plot was the environment (environment 1, environment 2), the split plot was vernalization temperature (3±2 and 9±2°C), and split-split plot was Gibberellin concentration (0, 50, 100, 150 ppm). The result showed that the vernalizations and Gibberellin have significantly affected plant height (p<0.01). The environment significantly affected plant height, number of tillers, and number of leaves. There was an interaction between Gibberellin and environment treatment on plant height and an interaction between vernalization, Gibberellin, and environment on the number of leaves. The environment with temperature: 29±2.18°C, RH: 45±9.14%, light intensity: 9272±7669 μmol m-2 S-1 showed plant height and the number of tillers higher than other environments, contrary to the number of leaves. According to the principal component analysis, this environment is more suitable for all vernalization and Gibberellin treatments than other environments. The results of this study indicate that the environment more influences vegetative growth than the other two treatments.

Shallot (Allium cepa L. var. aggregatum) is an important vegetable crop in Ethiopia, but its production has declined in recent years due to a lack of true seed-propagated varieties. This study aimed to demonstrate and evaluate the performance of true seed shallot varieties in three districts of the Amhara region: Fogera, Libokemkem, and Dera. The study involved the participation of host farmers in variety demonstrations and the evaluation of the demonstrated varieties by experienced farmers. Two true seed shallot varieties, DZsht-157-1B and DZsht-91-2B, were compared to the local Bombay red variety. Bulb yield data was collected from one-meter square quadrants, and farmers' preferences were assessed using a direct matrix ranking approach. The results showed that the true seed shallot varieties outperformed the local Bombay red variety in terms of bulb yield. In the Fogera district, DZsht-157-1B and DZsht-91-2B had 40.1% and 0.3% higher bulb yields, respectively, compared to Bombay red. In the Libokemkem district, DZsht-91-2B had a 4.2% yield advantage over the local variety. The farmer evaluation results revealed that the true seed shallot varieties were preferred over the local Bombay red variety in various aspects, such as higher bulb yield, redness, and prolonged food span. The findings of this study suggest that the true seed shallot varieties have the potential to improve shallot production in the study areas and potentially in other parts of Ethiopia. To promote the adoption of these varieties, it is crucial to ensure the availability and accessibility of high-quality seeds to farmers, as well as to educate them on the importance of maintaining the true seed to bulb and bulb to true seed cycle. This will enable the continuous propagation of the true seed shallot varieties and ensure a sustainable supply of high-quality planting material, contributing to the revitalization of shallot production in Ethiopia and enhancing the livelihoods of smallholder farmers.
