This work dealt w ith the effect of the in terval of; harvesting top growth on the storage of reserve carbohydrates in roots t underground s tem s, and stem b a ses of Sabi Guinea g ra s s . Percentage of to ta l a v a il able carbohydrates in the storage o rg an s, dry weight of th e se o rg an s, growth stage of the p lan ts , height of the f irs t l e a f , number of shoots per plant, and clump b asa l area, were determ ined every 15 days throughout the experim ental period. The cutting treatm ents stopped growth of the storage organs and Caused a temporary lowering of the percentage of reserve carbohydrates in th ese o rg an s.
