Effects of Peanut Intercropped and Trash Mulch on Weed Control and Growth of Sugarcane

Abstract

Investigation on the effect of peanut intercropped and trash mulch on weed control and growth of sugarcane were conducted during 1982-1987 at farmer's fields in suphan Buri and Nakhon-Pathom province. The results revealed that intercropping of peanut in plant cane could reduce weed infestation by 31.1%. In ratoon cane, mulching with sugarcane leaves provided better yield than unmulching by 48.4% in average. Trash mulch seemed to be beneficial for reducing weed dry weight and enhancing growth of sugarcane at the early stage of ratooning.
