YIELD AND QUALITY OF SWEET CORN (ZEA MAYS L. VAR. SACCHARATA) CULTIVARS GROWN ON DIFFERENT SOIL TYPES

A field experiment was conducted in order to determine the influence of contrasting soils oil sweet corn (Zea mays L. var. saccharata Korn.) agronomic characteristics, yield and soluble sugars content. A study with sweet corn was set up during 2006 in Slovenia at two locations: in clay loan) soil and in sandy loam soil. At each location 5 cultivars (Tasty Sweet Trophy F1, Tasty Gold F1, Cold Cup F1, Sweet Nugget and Zuckergold) were tested. The highest kernel weight cultivar was Tasty Sweet Trophy F1, regardless of the type of the soil texture. Kernel number per unit area was closely and negatively correlated with kernel weight. The type of soil had no significant influence on soluble sugars composition. However, when the sucrose content was observed, there were remarkable differences between cultivars irrespective of soil type.
