Cassava (Manihot esculenta Crantz) production in sub-Saharan Africa (SSA) is constrained by the two biotic constraints namely, cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). The aim of this study was to evaluate elite cassava genotypes for variation in agronomical traits, correlate them to CMD and CBSD parameters and identify stable genotypes in Alupe, Kakamega and Kibos in Western Kenya. Twenty three (23) elite cassava genotypes that had shown resistance to either one or both of CMD and CBSD in Eastern Africa were evaluated. The trial was conducted using an alpha lattice balanced design with twenty three (23) genotypes, replicated three times at Alupe, Kakamega and Kibos in Western Kenya for an extended cropping cycle between 2016 and 2017. Results showed significant differences (P ≤ 0.05) between genotypes and location (or agro-ecology), but not interaction (P ≥ 0.05), for all the agronomic performance parameters evaluated.
All the 23 cassava genotypes evaluated across the three locations had mean cyanide potential levels ranging from of 3.00–6.00 and were therefore, sweet and not bitter. The significant but negative relationship between CMD and CBSD incidence and severity with agronomic performance implied that their relationship was inverse. Confirmation of stability for agronomic performance was achieved through AMMI analysis, using AMMI stability value (ASV). Stable genotypes based on AMMI stability values (ASV) for fresh root yield across Alupe, Kakamega and Kibos were KBH/2002/066, Kibandameno (a local standard check), NASE-18, Kizimbani and NASE- 3. These genotypes need to be further evaluated in more environments to assess their wider adaptability and stability.

Miraa (Catha edulis forsk) farming is a major income earner in Kenya, but until recently, it was not scheduled as a priority crop in the country. Consequently, no gender research to identify men and women issues with the purpose of designing gender-responsive solutions for increased productivity has ever been conducted on the crop value chain. The main objective of the study was to examine gender issues in miraa production and marketing activities in Kenya. Data were collected using multiple methods. These included a formal survey that covered 962 households, key informants’ interviews, focused group discussions and a literature review. The household data were analyzed through descriptive statistics using SPSS Version 20 software. The Harvard theoretical framework was used to structure the analysis. The main findings indicate that women have less access to production resources such as land and extension services than men. Moreover, men performed almost all crop activities. Men also dominated all crop decisions. The study recommends that research scientists need to design gender-responsive technologies, innovations and management practices that are tailor made to meet men’s needs and concerns. This is because the crop appears to belong to men with less women’s operational and financial control.
