Abstract

A field experiment was conducted during 2004 in research field of Zanjan university in Zanjan province. The main goal was determining the effect of planting techniques and SEED RATEs on RAPESEED emergence, plant establishment and GRAIN YIELD. A factorial experiment in the form of randomized complete block design was applied with four replications. A pneumatic and a common mechanical PLANTER were used. Seeds were sown on flat and raised-bed with three levels of 5.5, 7 and 8.5 kg seed per hectare. Results showed that the planting machine had significant effect on seedling emergence (P≤0.01) and mechanical PLANTER had higher seedling emergence than pneumatic PLANTER. Mechanical PLANTER with the amount of 8.5 kg/ha seed had higher seedling emergence (P≤0.01) than others. Proper seed depth of mechanical PLANTER was significantly greater (P≤0.01) than pneumatic PLANTER. Pneumatic PLANTER had higher post-winter plant establishment in comparison with mechanical PLANTER (P≤0.05). Mechanical PLANTER with flat PLANTING METHOD had minimum postwinter plant establishment (P≤0.01). Grain per hectar was higher by using pneumatic PLANTER with flat PLANTING METHOD when 8.5 kg/ha seed was applied at sowing. It was not significant.
