Abstract

In order to study effects of sowing depth and SEED SIZE on growth and yield of CORN hybrid SC704, an experiment was conducted in 1996-1997 at Ramin Agricultural Research and Education School of Shahid Chamran University. The design of the experiment was a split plot in which main plots were consisted of 2 sowing time (August 9 and 21), subplots were collected of 3 sowing depth (2, 4.5 and 7 cm) and sub subplots were 4 SEED SIZE (5.9-6.1 mm as small, 6.9-7.1 mm as medium, 7.9-8.1 mm as large size and mix) in randomized complete block with 4 replications. Analysis of variance showed that sowing depth and SEED SIZE affect seed emergence, which inf1uence growth and yield. Low sowing depth (2 cm) with uniform seeds compare to mix seeds induce uniform emergence and same time germination without competition in emergence time, therefore yield of CORN increased. With medium sowing depth (4.5 cm) large and mix seeds GRAIN YIELD.increased significantly. More sowing depth (8 cm) in compare to low and medium depth, small seed and latter medium SEED SIZE had higher yield than large and mix seeds. Among yield components, number of kernels per row (41.93) in surface planting (2cm) with large seeds size was more than other size of seeds. In medium sowing depth (4.5 cm) mix seeds had highest number of kernels per row (41.41). In 7cm sowing depth number of kernels per row was 42.45. The results of this study suggest that increase in sowing depth caused a delay in germination, emergence of seedlings and relative growth of plants. Thus yield would be reduce.
