A five-factor rotary regression test on precision sowing of wheat in suburbs of Beijing






Beijing Agricultural Sciences 17(4): 1-4

A five-factor rotary regression test on precision sowing of wheat in suburbs of Beijing

Tests on wheat cultivation were conducted in 1997-98 at the experimental station of Beijing Agricultural College. The effects of the test factors on wheat production followed the order of nitrogen fertilizer > sowing date > phosphorus fertilizer > density > dressing frequency of nitrogen fertilizer; nitrogen fertilizer, phosphorus fertilizer, and dressing frequency of nitrogen fertilizer had positive effects while sowing date and density had negative effects.
