Effects of Population Density and N-fertilizer on The Yield and Ear Quality of Super Sweet Corn
C. L. Tsai and H. W. Chung
Super sweet corn (Zea mays L.) variety Tainan No. 15 was grown at the experimental field of Corn Research Center, located at Potzu, Southern Taiwan, during 1981-1982, to evaluate the effects of population density and N-fertilizer rates on yield and quality of the ear. The results showed that total ear yield increased with and increase in population density; however, single ear weight and ear length were decreased at the higher density. Nitrogen fertilizer showed no consistented effect. There were no significant interactions of population densities and N-rates on yield and single ear weight.
