栽培密度與氮肥用量對超甜玉米之產量與品質的影響

蔡承良 鐘華月

摘  要

超甜玉米在本省主要是供應鮮食市場,品質的好壞影響價格的高低,因此,欲提高種植超甜玉米的收益,必需同時考慮產量與品質。本試驗的主要目的在探討栽培密度及氮肥用量對超甜玉米的產量及品質的影響。試驗結果顯示增加栽培密度可提高果穗產量,但果穗較短,單果穗重較輕。氮肥效應則無一致的趨勢;且栽培密度與氮肥用量之間亦無明顯的交感效應。


Effects of Population Density and N-fertilizer on The Yield and Ear Quality of Super Sweet Corn

C. L. Tsai and H. W. Chung

Summary

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.
