Abstract :

This experiment was conducted based on split plot layout with completely randomized block design with 3 replications In the summer 2015 in an experimental farm, in Shushtar. Where planting pattern as main plots in three levels: 1- normal planting pattern (one row center stack), 2- two-row planting in the region Daghab and facing each (mutual) on a stack, 3- Planting as zigzag double row distance of 30 cm on stacks at a distance 75 cm and sub-plots  Includes four types of maize cultivar: 1- S.c 704, 2- S.c 706, 3- Bolsen. and 4- A.s 73. The results showed The difference between the different levels of planting patterns on The number of rows per maize and grain yield significant at %1 level of probability and on stem height, thousand grain weight and seed number per row was significant at %5 level of probability. The difference between the cultivar in number of seeds in row and grain yield significant at %1 level of probability and on stem height, number of rows per maize and thousand grain weight was significant at %5 level of probability. The highest grain yield in zigzag planting pattern with KSC 706 cultivar with 8247/59 kg/ha was. According to the results, application of double row zigzag planting pattern with cultivar new KSC 706 can With improve the physiological growth indices, The highest yield and yield components in the region gained.
