Abstract: Improving the yield of ivorian kola orchards involves creating high-performing plant material. The use of seed nuts faces challenges due to slow germination and late fruiting of the resulting plants. Therefore, the production of grafted plants with high-yielding clones is being considered. The objective of this study was to determine the effect of the clone on the success rate of plants grafted with Cola cordifolia and, by extension, to determine the effectiveness of the rootstock type Cola cordifolia. Five clones are involved: AMA, BOGO, DIDI, MOUSS, and SELI. The experimental design was a completely randomized design with one factor studied (Clone) and three replications. Cleft grafting was performed in a nursery under a tunnel. The experimental unit consists of 10 plants. The success rate of the plants was measured after two months of experimentation. Results showed an average success rate of 55.33%. The genotype had a significant effect on the number of successful grafts. The success rate varied depending on the clones, ranging from 36.67% to 63.33%. The DIDI clone had the lowest success rate, while the SELI clone had the highest success rate and produced the largest number of new leaves, followed by the AMA clone. These SELI and AMA clones show good grafting aptitude and rapid recovery after grafting. Thus, cleft grafting applied to Cola cordifolia as a rootstock is advantageous for the multiplication of C. nitida. Cola cordifolia could therefore be proposed in the future to kola producers as an alternative rootstock to Cola nitida for grafted plant production. However, the grafting aptitude of clones proposed for distribution should be systematically evaluated. Grafted plants with Cola cordifolia should also be tested in the field.

Abstract: Barley (Hordeum vulgare) is an important food crop in the highland parts of Ethiopia. The main purpose of this activity is to demonstrate improved food barley technology through a cluster based crop production approach. Sites and farmers are selected purposively from the major food barley producing areas of West, and North Shewa, zones of Oromia. About 182 participant smallholder farmers are involved through clustering their farm fields. In this study, one popular food barley variety (HB1307) with its recommendation packages is used for demonstration purpose. Accordingly, a total of 113 hectares of land with 15.65 ton of seed of food barley is covered. The quantitative and qualitative data are collected using participatory rural appraisal tools. The yield data are collected from the entire participants of the cluster and analyzed by simple descriptive statistics. Generally, the variety (HB 1307) demonstrated is found it acceptable by farmers in field visits and field days because of its resistance to disease, adaptation, and productivity. Moreover, the finding of the three years demonstration result revealed that the full package food barley variety (HB1307) demonstration through cluster approach has higher grain yield than the national and regional average recorded in the season. Therefore, the best-performing variety of food barley in the study area is HB1307, based on the data. Thus, improved variety with recommended production packages should be further scale out in the study area and similar agro-ecology using cluster farming approach.
