- Abstract
Increasing maize yield per unit is the most important measure to address food security issues. Farmers from northeastern China created several cropping patterns to increase yield per unit, but which pattern is the best has not been researched. A randomized block design of six cropping patterns and four replicates was used. Six cropping patterns 65cm×65cm, 40cm×90cm, 30cm×100cm, 20cm×110cm, 2L:0 and 4L:0 respectively were studied. The results showed that all wide and narrow rows patterns and free-sow patterns have higher yield than the same spacing patterns, and 30cm×100cm is the optimal pattern to obtain the highest yield, followed by 20cm×110cm, 4L:0, 2L:0, 40cm×90cm and 65cm×65cm respectively. If all farmers carried out the 30cm×100cm pattern, problems on food security in China would be obviously improved.
