Effects of Increasing Density and Fertilizer on Yield and Agronomic Characters of Rain-fed Spring Corn
In order to explore the techniques to improve the yield of spring corn in the rain-fed area of northwest Hebei Province,we set up treatments of density and fertilizer increasing treatment and single application of organic fertilizer treatment,with local planting patterns as the CK.The agronomic,ear and yield characters of spring corn were monitored.Results showed that density and fertilizer increasing treatment en-hanced the bald tip rate,reduced the 1 000-grain weight and ear per grains,and its yield enhanced by 5.3% significantly.Single application of organic fertilizer treatment enhanced the grains per ear and 1 000-grain weight,reduced the bald tip rate,and its yield enhanced by 10.4% significantly.Compared with CK,the 1 000-grain weight and yield of the two treatments had significant differences with those of CK.Thus,in-creasing planting density and fertilizer could enhance the yield of rain-fed spring corn in dry farming areas.
