 Abstract

 

Seed rate in the Kenya sugar industry ranges from 5-12 tha-1 or 25,000-35,000 three budded setts ha-1. A study was conducted to determine the most economic seed rate for newly selected sugarcane cultivars at Sugar Research Institute, Kibos in March 2011. Sugarcane cultivars CO 421, KEN82-62, KEN82-247 and KEN85-53 were each planted at the rates of 3, 5, 7 and 9 tha-1. Diammonium phosphate (DAP) fertilizer was used across all treatment combinations at the rate of 80 kg P2O5 ha-1 at planting, while urea was used to top dress at 100 kg N ha-1 five months after planting (MAP). The trial was harvested at 20 MAP plant crop for yields and milling. The results showed that germination percent differed significantly among the treatments with KEN82-247 showing the highest germination (68.8%) and KEN85-53 showing the lowest (30.6%). Tiller numbers differed among the cultivars at the 5th and 7th MAP. Similarly, KEN82-247 showed the highest tillers number and KEN85-53 the lowest. There were no significant differences among the seed rates. Significant difference in yield components and yield among the cultivars were noticed with KEN82-247 out yielding the other three cultivars. The seed rates minimum cost analysis was adopted, which shows that the lowest cost (3-5 tha-1) is hereby recommended as the most cost effective seed rate for cane growers in Kibos sugar zone.

Key words: Seed rate, cultivar, setts and minimum cost analysis.
