摘要

Livestock production depends on quality and quantity of forage which can be influenced by fertilizer application ( Forth 1984).Pasture improvements techniques in tropical and subtropical areas of Yunnan have largely centered on the use of new species of plants which had been introduced to China from Australia.Less is known about how nutrient limitations may limit forage quality and yield.This study examined the effects of boron (B) on the density, growth, seed yield and nutrient concentrations of Centrosema pubscens in terms of nutrient requirements.Yield improvements with B addition could greatly assist animal husbandry in humid subtropical areas of Yunnan.
