The birds were allotted into six dietary treatment groups of 30 birds per treatment and 3 replicates of 10 birds each. The test ingredients were mixed at a ratio of 1:1 and the blend ingredient was included in the treatments at T1(0g), T2 (2 g/kg), T3 (4 g/kg), T4 (6 g/kg), T5 (8 g/kg) and T6 (10 g/kg) inclusion levels. Data were collected on egg production performance and egg quality; they were analyzed using one-way analysis of variance (ANOVA). The highest (p &lt; 0.05) hen day production (87.88) was recorded with layers bird-fed diet containing (2 g/kg) while layers fed control diets (0g/kg) had the least (71.17). The highest (p &lt; 0.05) feed intake/egg (265.72 g) was recorded with layers’ bird-fed diet containing 2 g/kg of Jimson weed and turmeric blend while layers fed a control diet (0 g/kg) had the last (219.75g). The highest (p &lt; 0.05) albumen (62.60 g) was recorded with layers bird-fed diet containing (4g/kg) while layers fed diet containing (8 g/kg) of jimson weed and turmeric blend had the least (59.31 g). The highest (p &lt; 0.05) yolk (26.78 g) was recorded with layers bird-fed diet containing 6 g/kg of Jimson weed and turmeric blend while layers fed a diet containing (4 g/kg) had the least (23.30 g). It could be concluded that the use of jimson weed and turmeric blend in diets had a positive effect on production performance and egg quality of laying birds. It is therefore recommended that feeding layers birds with a diet that contains 2 g/kg, 4 g/kg and 6 g/kg of Jimson weed and turmeric blend will aid better production performance and egg quality.</p> Tunji Babatunde Olayeni Tirimisiyu Adewale Rafiu Eden Olusegun Okanlawon Olakiitan Sangoniyi Ridwanullahi Hussain Sukurat Opeyemi Adegoke John Ayomide Akinlabi Femi Tosin Akinboade Copyright (c) 2025 Tunji Babatunde Olayeni, Tirimisiyu Adewale Rafiu, Eden Olusegun Okanlawon, Ridwanullahi Hussain, Sukurat Opeyemi Adegoke, John Ayomide Akinlabi, Femi Tosin Akinboade https://creativecommons.org/licenses/by/4.0/ 2025-01-30 2025-01-30 2 2 1 6 10.14295/cerrado.v2i2.704 https://periodicos.cerradopub.com.br/cerrado/article/view/724 <p>Chickpea (<em>Cicer arietinum</em> L.) is a member of the legume plants and it has genomes with 16 chromosomes (2n = 2x = 16). The use of poor yielder local chick pea varieties was the problem of chickpea production in Ethiopia. Therefore, the present study designed to investigate the variability and adaptability of Kabuli chickpea varieties for yield and yield component traits. It was specifically, to evaluate genetic adaptability of Kabuli chickpea varieties and to identify promising candidate varieties to be used in Kabuli chickpea production. The study was carried out on 13 Kabuli chickpea varieties and the experiment was laid out in a complete randomized block design at two locations with arrangement of 13 x 3 for each location. Results obtained on variability assessment and associations among yield related traits presented here. The analysis of variance showed highly significant variation among the varieties for all the traits at each location. Qobo with 4153 and 3932 kg ha^-1, Kasech with 3839 and 3767 kg ha^-1, Qoqa with 3673 and 3543 kg ^-1, Akuri with 3083 and 2883 kg ha^-1 yield Kabuli chickpea varieties were top four potential and better performing varieties to distribute for farmers further adoption and yield improvement under different agro-ecologies.</p> Haile Tefera Abebe Misganaw Seid Hussen Copyright (c) 2025 Haile Tefera, Abebe Misganaw, Seid Hussen https://creativecommons.org/licenses/by/4.0/ 2025-05-20 2025-05-20 2 2 7 24 10.14295/cerrado.v2i2.724
