Abstract

Leucaena leucocephala cv. Peru was sown with a dressing of 0, 30 and 60 lb of fertilizer nitrogen per acre, plots being weeded or left unweeded. Significant responses to weeding and nitrogen were obtained. On weeded plots there was no increase in production from 30 lb Of nitrogen to 60 lb of nitrogen.
