Abstract

The effects of nitrogen and phosphate on Siberian wildryegrass ( Elymus sibiricus L.) were studied. The result showed that the seed yield increased greatly with a suitable nitrogen of phosphate treatments. A fertilizer application of 80kg N and 50kg P\-2O\-5 per hectare was recomended, which the seed yield increased to 1027kg/hm\+2, increased by 129%. The seed yield components were changeable with different fertilizer treatments; The number of seed per spikelet is the most important factor in all the components.
