Abstract

This experiment was conducted to study the effect of plant density (pd) and planting pattern (pp) on YIELD and YIELD components of two CORN hybrids. The type of design was randomized complete block with factorial arrangement and three replications per treatment in 2003 growing season at Gerizeh agricultural station, in Sanandaj. The treatments were plant density (65000, 75000 & 85000 plant per hectare) and planting pattern (normal planting pattern, i.e. planting seeds at the center of ridges; two rows planting on the sides of wide ridges i.e. every other furrows removed and zigzag planting patter, i.e. two rows planting on the sides of normal ridges as zigzag) and two CORN hybrids (KSC700 and KSC704). The results of the experiment showed that increasing plant density significantly increased seed YIELD. Maximum seed YIELD 11122.5 kg/ha obtained at highest plant density; but there were no significant differences between 75000 & 85000 plants/ha. Number of ears per plant, number of seeds per ear, number of seed rows per ear, number of seeds per seed row, 1000 kernel weight and harvest index were not affected by plan density. Planting pattern had significant effect on seed YIELD. Zigzag planting pattern produced highest seed YIELD (11054.7 kg/ha) and lowest seed YIELD was belong to every other furrow planting pattern. Number of ears per plant, number of seeds per ear, number of rows per ear and number of seeds per ear row were not affected by planting pattern; whereas, planting pattern effect on 1000 kernel weight and harvest index was significant. Zigzag planting pattern had maximum and every other planting pattern had minimum 1000 kernel weight and harvest index, respectively. CORN hybrid effect on seed YIELD, ear number per plant, seed number per ear and seed number per ear row was not significant. Seed rows number per ear in KSC700 and KSC704 were 16.33 and 13.92, respectively, this difference was significant. 1000 kernel weight and harvest index of two hybrids had significant differences. 1000 kernel weight of KSC700 and KSC704 were 267.97 and 244.61g and harvest index was 52.04% and 50.01%, respectively. KSC 704 in 85000 plt/ha and zigzag planting pattern produced highest seed YIELD and lowest seed YIELD was belong to KSC700 in 65000 plant/ha and every other furrow planting patter.
