查询词典 efficiency engineer

To estimate the quantitative genetic parameters of nitrogen use efficiency, twenty maize single-cross hybrids with varying nitrogen use efficiency were tested at two locations in the North China Plain. At both locations, the hybrids were grown under high (HN, 225 kg/hm^2 N) and low N levels. And no N fertilization on the LN field have lasted two years.
