dc.description.abstractLow potato yields are mainly attributed to the use of poor seed potato propagules at planting time, along with poor crop husbandry. Lack of good agronomic practices (GAP) is associated with lack of adequate practical training of students, extension officers and farmers along the seed potato value chain. This situation can be reversed by training potato value chain (PVC) stakeholders through experiential learning as proposed by the seed potato community action research project plus (CARP+) hosted by Egerton University. This process involves seed potato stakeholders participation in a joint learning process along PVC. Through a multi- stakeholder platform, (MSP), Egerton University (academia- cum- researchers), seed producers (ADC-Molo, AGRICO, Stockman Rozen in collaboration with the international potato centre (CIP), Nakuru farmers associations and cooperatives, input suppliers (Baraka Fertilizer), and the Nakuru County government, extension services of the Ministry of Agriculture (MoA) set out on-farm demonstrations with the aim of supporting experiential, i.e., learning through active participation. This process was jointly supported by the seed potato Community Action Research Project plus (CARP+) and above mentioned seed potato private sector. Furthermore, stakeholders jointly harvested the crop at maturity, the descriptive statistical analysis was performed and all varieties evaluated for suitability for processing as chips, crisps or boiled. The potential yield performance revealed that manitou had the highest tuber yield of 71.2 tons/ha (88% Market yield), followed by Unica at 54.5 tons/ha (80%), compared to shangi (control) with 56 t/ha total yield and 70 % marketable yield. All potato yields obtained from apical rooted cuttings (and no of stems and no. of tubers /plant) were lower than those obtained from tubers. This was attributed to their high status (breeders – pre-basic) as compared to tuber propagules that were at certified 2 (C2). The highest proportion of seed tubers in all varieties was Size 1 (28 – 48mm) with Shangi having the highest number of tubers/plant, at 12 and 6 tuber/plant, from crops produced through tubers and apical rooted cuttings, respectively. For ware potatos, only Manitou, Unica and Rudolph had tubers bigger than 100mm. The later prove to be better for chips processors due to their large size and ease at pealing. When it came to suitability for processing, the overall average scores reveal that Dutch (48.7 %) followed closely by Manitou (46.7) and Wanjiku (44/6%) were generally better scored across the three processed products. However, Dutch performed highly (73 % preference) for crisping. Wanjiku (47%), Manitou (40%) and Dutch Robijn (33%) were found to be satisfying the consumers for French fries. Concerning consistency of boiled potatoes, it was found that only Sherekea (40%) was the most satisfying variety. All the stakeholders, in particular the farmers students and faculty, were able to appreciate the importance of discriminating the choice of varieties to grow for different market and processors.en_US
