Tomato, Lycopersicon esculentum is a highly perishable horticultural crop,
which requires high level of post-harvest management to prevent losses during harvesting,
packaging and transport. The study aimed at assessing the influence of knowledge levels of
postharvest handling technologies on tomato quality among smallholder farmers in of Kisii
and Nyamira counties, Kenya. The study sampled 168 respondents from the target
population of 1001 registered smallholder tomato farmers in the two counties using
random and purposive multilevel sampling designs. Data was collected using semistructured
questionnaires and interview schedules after determining the validity and
reliability of the data collection tools. Descriptive statistics; mean, frequencies and
percentages, and one-way ANOVA were performed using the Statistical package for social
sciences (SPSS version 21, IBM Inc.) and the statistical significance of the differences of
knowledge among the smallholder farmers levels judged at p = 0.05. There were significant
differences (p < 0.05) in postharvest management knowledge levels among smallholder
farmers. The overall mean (3.24 ± 0.822) indicated that smallholder farmers had moderate
level of knowledge on tomato postharvest handling technologies. The means for packaging
(3.49 ± 1.210) and transport (3.48 ±1.229), were significantly higher (p < 0.05) than other
post-harvest technologies, with precooling (2.1±1.3) recording the lowest mean. Adoption
of recommended post-harvest practices is determined by knowledge levels among the small
holder farmers. Therefore, the study recommends the involvement of other advisory channels in training smallholder farmers to improve their awareness on postharvest
handling technologies to reduce tomato quality deterioration.
