Abstract

in order to study the sowing date,SEED SIZE and PLANTING DEPTH on yield components and yield of CORN (Zea mays) K.S.c500, A split-split plot experiment in a compeletely randomized design was conducted at Islamic Azad university, Khoramabad branch during 2003-2004.the two sowing data (Second and 12th of august) were allocated in the main plots and PLANTING DEPTH at three levels as 2, 4.5 and 7cm,and SEED SIZE (5.8-6mm, 4.9-7.1 mm, 7.9-8.1mm and mixed seed) were assigned in sub and sub-sub plots, respictvely. Result showed that SEED SIZE and PLANTING DEPTH had significant effects on exegence and plant growth, development and yield. Sowing Date and depth of planting had significant effect on plant yield. Depth of sowing (7cm) with SEED SIZE (5.8-6mm, 6.9-7.1 mm) was superior for plants yield and depth of planting (4.5cm) with mixed seed and depth of planting (2cm) with mixed seed get second and third place for plant yield. Small seeds (5.8-6mm) ubsorbed high soil moisture (high Ratio of surface to volume) and had suitable emerging with high yield (planting depth, 7cm). Depth of planting (7cm) had maximum stem elonyation rate in all SEED SIZE. High temperature stress had no important effect on water adsorption (planting depth, 7cm).The interaction effect between time of sowing, PLANTING DEPTH and SEED SIZE for plant height was significant. Depth of planting (2cm) with SEED SIZE (7.9-8.1 mm), depth of planting (4.5cm) with mixed seed and depth of planting (7cm), with SEED SIZE (5.8-6cm) producted maximum number of seed per row.
