LIKUI XU, BINRONG PAN, GAOHONG YUE, XIXUE MEI, YONGAN LIU, ZONGCHEN ZHANG and ZHIHUI ZHOU, 2014. Effects of Ridge-planting Pattern on Agronomic Traits, Quality and Yield of Sweet Corn in South China. Bulg. J. Agric. Sci., 20: 145-149
As a method to avoid waterlogging, ridge planting is widely adopted in sweet corn (Zea mays saccharata Sturt) cultivation in south China. The effects of ridge-planting pattern on agronomic traits, quality and yield of sweet corn were studied in 2012. Sweet corn Jinyutian No. 1 hybrid (sh2) and four ridge-planting patterns were used, and the experimental was designed as a randomized block with three replications. The results showed that ridge-planting pattern almost had no effect on leaf number and chemical properties (moisture, total sugar and starch content) of sweet corn. Although the physical properties (fresh- and husked-ear weight, ear length, kernel rows, kernels per row, ear diameter, kernel depth and 100-kernel weight) of Pattern 3 were higher than other three patterns, the plant density and agronomic traits (leaf area per plant, leaf area index, plant and cob height) of Pattern 1 were higher and the corn stalk rot mortality of Pattern 1 was lower than other three patterns, and the freshear weight of Pattern 1 was higher than Pattern 2 and Pattern 4 all the time, and was lower than Pattern 3 significant only at 21 DAP. As a result, the yield of Pattern 1 was higher than other patterns significantly all the time.
