A seeder should place seed in an environment for reliable germination. The main objective of sowing is to put seeds at adesired depth and spacing within the row. Uniform seed distribution within soil result in better germination andemergence and increase yield by minimizing competition between plants for available light, water, and nutrients. Anumber of factors affect seed distribution in soil. Seed metering system, seed delivery tube, furrow opener design,physical attributes of seed and soil conditions all play a part in determining seed distribution. The demand for uniformdistribution into the soil of grain seeds and especially small grain seeds has increased during the last decade.Improvements had been made on new metering devices, furrow openers and grain flow. The present research wasfocused on improving seed distribution into the soil, regarding the furrow opener design and grain flow. Research wascarried out in the Department of Mechanisation of the Faculty of Agriculture of the University of Agronomic Sciencesand Veterinary Medicine of Bucharest and used a three row simulator of a conventional grain drill.
