Cultivation of Mango is an important venture in Ethiopia especially in Amhara, Beneshangul, Oromia, and SNNP regions. However, challenges such as low yields and inconsistent fruit quality persist, particularly in Amhara region. This study was conducted to evaluate the performance of four commercial mango varieties at Woreta in the Fogera district o...

The goal of potato breeding is to develop widely adaptable, highly productive cultivars that farmers would prefer. The objective of this study was to evaluate the performance and stability of potato varieties linking the preferences of smallholder farmers in rain-fed and irrigated environments. Using a randomized complete block design in three repl...

One of the fundamental goals of plant breeding is to evaluate genetic diversity in crop species, which aids in the development of breeding approaches. Therefore, this field experiment was conducted to assess mean performance, the genetic variability in garlic genotypes on bulb yield and related traits. The field evaluation of thirteen garlic genoty...

Assessing the genetic diversity of crop species is one of the main objectives of plant breeding since it helps with the creation of breeding strategies. Thus, the purpose of this field experiment was to evaluate the genetic diversity and mean performance of garlic genotypes on bulb yield and associated variables. The field evaluation of nineteen ga...

The experiment was conducted during main rain fall season from June to October, 2018 in Adet, Ethiopia with the objective of estimating the correlation and identifying the direct and indirect effect of yield contributing traits on potato crop. 36 potato genotypes were evaluated in simple lattice design in two replications. The analysis of variance...

Experiments under field conditions were conducted in the Meher season from mid-July to December 2019 and 2020 at Kulumsa and Arsi Robe, Southeast Ethiopia. The study intended to evaluate white cumin accessions for agronomic and quality traits. Fifteen genotypes were laid out in a randomized complete block design in three replications. The analysis...

Lettuce (Lactuca sativa L.) is one of the most popular salad crops and occupies the largest production area among salad crops in the world. However, production of lettuce can be limited due to lack of improved varieties for different agro-ecologies. Adaptable high yielder released lettuce varieties were not identified for farmers of Fogera and Libo...

The objective of this study was to assess the extent of variability of yield and yield-related traits, heritability, and genetic advances among Ethiopian coriander accessions. The experiment was conducted at Kulumsa Agricultural Research Center, Southeast Ethiopia, during 2019- 2020 cropping seasons. Twenty-five Ethiopian coriander accessions were...

A field experiment was conducted at the Kulumsa Agricultural Research Center in Southeast Ethiopia during the meher season (July to November 2019 and 2020) to evaluate the extent of variability, heritability, and genetic advance of eight yield and yield-related variables among 25 Ethiopian coriander accessions. A 5×5 simple lattice with two replica...

Multi-environment trials were carried out at 3 locations in different black cumin growing zones of Ethiopia during June-December, 2017–2018 and 2018–2019 to select high yielding and adaptable genotypes for commercial production in Ethiopia. Ten advanced black cumin genotypes were evaluated with one standard check variety. The genotypes were arrange...

to select high yielding and adaptable genotypes for commercial production in Ethiopia. Ten advanced black cumin genotypes were evaluated with one standard check variety. The genotypes were arranged in Randomized Complete Block Design with three replications. The ANOVA revealed that the differences in seed yield among genotypes (G), environments (E)...

The experiment was carried out under rain fed conditions for three consecutive years (2017–2019) from mid-June to mid-October at Bekoji and Kofele sub sites of Kulumsa Agricultural Research Center, Ethiopia by using improved varieties to identify superior genotypes. The experiment was laid out in a randomized complete block design with three replic...

An apple tree pruning experiment was conducted to investigate the effect of pruning time on yield and quality of apple fruits at Kulumsa Agricultural Research Center, Southeast Ethiopia, during the cropping seasons of 2019 and 2020, in two sets each year. Eight treatment combinations of two varieties (Ana and Princesa) and four times of pruning...

Farmers in South Gondar zone were using broadcast transplanting in flatbeds with border ridges to produce onion in the dry season. On the other hand, the research recommendation is to transplant onion seedling in furrow and ridge with double row plantings of 40 cm x 20 cm inter row spacing. This study was therefore initiated to demonstrate to farme...

Potato is a high potential food security crop in Ethiopia. Genetic variability is the basis of all crop improvement programs. The study was conducted at Adet in 2018 with the objective of assessing the extent and pattern of genetic variability of potato genotypes for yield and yield related traits. A total of 36 potato genotypes were evaluated for...

Onion is one of the most important vegetable crops in the world including Ethiopia. The field experiment was conducted in Arsi zone at Kulumsa Agriculture Research Center and Ziway Dugda districts under irrigation condition. A total of five improved onion varieties were evaluated in Randomized Complete Block Design with three replications with the...

Shallot (Allium cepa var. ascalonicum Backer) is an important vegetable crop cultivated by smallholder farmers for consumption and income generation in Ethiopia. However, scarcity of high yielding varieties as well as lack of superior planting material seriously constrains productivity of the crop. Research project was initiated aiming at studying...

Potato (Solanum tuberosum L.) is one of the most important food crops worldwide including Ethiopia. The study was conducted at field condition to evaluate the performance of potato genotypes for their tuber yield and yield related traits at Bekoji from 2014 to 2015 under rain growing season in RCBD with three replication. The analysis of variance (...

Potato is one of the most important crops in the farming system of Bekoji and Kofele in the cool highlands of Arsi where potato is usually grown biennially during the main and 'bulg' seasons. 'Belete' has been the dominant potato variety in these areas for the last ten years now and farmers prefer to grow this variety for its high productivity and...

Development of recommendation on appropriate plant spacing is one of the important agronomic practices to increase the productivity of carrot. Therefore, a field experiment was conducted to assess the response of carrot variety AU-18 to different inter-row spacing in 2018 and 2019 using irrigation. Three inter-rows spacing of 50, 75 and 100cm were...

Black cumin is the major and the most important spice in Southeast highlands of Ethiopia. However, the yield of the crop is very low mainly due to lack of optimum plant density. A field experiment was done with the objective to assess the influence of different seed rates and inter-row spacing on yield and yield attributes of black cumin at Kulumsa...
