Effects of single irrigation on yield and WUE of siberian wildrye grass in agro-pastoral transition zone of China

摘要：

Introduction The recent studies showed that deficient irrigation increased water use efficiency ( WUE) whereas full irrigation decreased it ( Waldron et al.,2002).Recent research on the relationship between forage dry matter yield and total evapotranspiration (ET) showed linear and curvilinear relationships ( Nielsen et al.2006 ).Irrigating in the elongating stage increased the growth of siberian wildrye grass significantly,and forage yield could benefit.
