Low sugarcane productivity is widespread and has persisted in all zones in western Kenya over the last decade despite the release of many improved sugarcane varieties during the same period. Three sugarcane varieties, two potassium and four nitrogen rates were randomly arranged in a split-split plot design with three replications under two sugarcane cropping systems. Data were collected on chlorophyll concentration, agronomic yields, agronomic efficiencies and quality parameter. The data were managed and subjected to statistical analysis systems (SAS) version 8.2 for analysis of variance (ANOVA); means were separated by least significant difference (LSD) at five percent significant levels. Results showed low chlorophyll concentration except at 13 MAP, inconsistent responses to N and K applied with non significant differences in productivity and agronomic efficiencies under both cropping systems. However, sugarcane quality data indicated that plant crops of all varieties tested should be harvested at 19 MAP. The study recommends use of both integrated nutrient management and improved legume fallows in the current sugarcane cropping systems; this is not only to improve sugarcane productivity but also to enhance nutrient supply through soil organic C improvement. Harvesting sugarcane plant crops at 19 MAP enhances sugar production through maximization of sucrose content.
