Abstract:

Abstract: The aim of present study is evaluation of the effect of different row spacing (15cm, 25cmand 35cm) and seed rates (100 kg/h, 150 kg/h and200 kg/h) on growth, biomass production (above and below ground), and grain yield of oat in east part of Horqin sandy land, Northern China. The study also aims to determine a combination of row spacing and seed rate for maximum vegetation coverage to prevent wind erosion in the soil. The result indicates that the combination of 150 kg/h seed rate of with 25 cm row spacing perform best with production of 3200.2kg/hm2 above ground biomass, 2773.6kg /hm2 below ground biomass and 1400.0 kg/hm2 grain yield in 2008. The same combination also shown height vegetation coverage (79.9%) provided by standing stubbles after harvest. And the result indicates that the combination of 150 kg/h seed rate of with 15 cm row spacing perform best with production of 1520.1kg/hm2 above ground biomass, and 688.9kg/hm2 grain yield in 2007. The result indicates that oat can grow well in sandy soil in addition it can effectively control wind erosion and improve the local environment.
