Monitoring the Influence of Scale of Operation and Farmers’ Risk Aversion on Sugarcane Productivity in Nandi County, Kenya

Aims: Sugarcane ranks among top ten commercial crops grown in Kenya, but its productivity has
been on the decline. It is a major source of sugar for human consumption, for industrial products such
as ethanol and by- products such molasses which are used as livestock feed among other uses. This
study investigated influence of scale of farm operation and farmers’ risk aversion on productivity. Risk
aversion was based on farmers’ perceived risks associated with new high yielding, early maturing
varieties.
Study Design: The survey study adopted an ex post facto research design.
Place and Duration of Study: The study was carried out in Nandi County, Western parts of Kenya
along a sugarcane growing belt. Data was collected between April and September, 2019.
Methodology: An enumerator-administered questionnaire was used to collect data from a sample of
198 respondents. Purposive and stratified random sampling techniques were used to select
participants. Data was analyzed with the aid of SPSS Version 20. Chi square test and its related
measure of strength of association; Cramer’s V, were utilized to estimate relationships between
variables. Welch’s ANOVA (W-test) was run to test for yield differences between groups. Significant
differences were subjected to post hoc tests using Games-Howell test to separate the means.
Results: There was a significant association between farmers scale of operation and productivity; 2
(2, N = 198) = 14.11, P = .001, V = .267. Farmers scale of operation significantly influenced
productivity based on W-test (P = .001). Medium scale farms were significantly more productive per
unit of land than both small and large scale. Risk aversion as measured by perceived risks of
changing to new varieties was associated with sugarcane productivity; 2 (2, N = 198) = 9.25, P =.01,
V = .216. Those who perceived high risks associated with new varieties recorded significantly lower
yields compared to low risks (P = .001).
Conclusion: The study concludes that the scale of farm operation had a significant influence on
sugarcane productivity. Small scale and large scale farmers experienced low sugarcane productivity
compared to medium scale. Risk aversion among the farmers appeared to negatively influence
sugarcane productivity. Capacity building of the farmers on crop management best practices and risk
management strategies is recommended.
