Abstract：Five different row spacing patterns were used to study their influences on the agronomic traits and yield of the new maize cultivar Xindan 38.Four patterns were set with equal row spacing as 0.5, 0.6, 0.7 and 0.8 m, and one was set with wide row spacing as 0.8 m and narrow row spacing as 0.4 m.The agro-nomic traits including planTheight , ear height , tassel main axis length , tassel branch number , total leaf num-ber, leaf number above ear and the internode length between the 7th, 8th and 9th nodes were investigated . The results showed that compared with the other row spacing patterns , the ear height was lower and the yield was the highest under the 0.6-meter equal row spacing pattern .Under the 0.8-meter equal row spacing pattern, the planTheight was relative lower;the internode length between the 8th and 9th nodes was relative shorter;the tassel branch number was relative less , and the yield was significantly lower than the other pat-terns.In conclusion, the optimum patter for Xindan 38 was 0.6-meter equal row spacing.
