Effects of Seed Drop Height and Tillage System on the Emergence Time and Rate in the Single Seed Planters

This study was conducted to determine the effects of seed drop height and tractor forward speed in different tillage systems on the mean emergence time, emergence rate index, and percentage emergence in single seed planters. The experiments were carried out in the conventional and reduced tillage systems, at seed drop heights of 120, 180, and 240 mm and tractor forward speeds of 1.1, 1.5, and 2.2 m s-1 . Sunflower and maize seeds were used in the study. The results of the study showed that seed drop height significantly affected the mean emergence time, emergence rate index, and percent emergence in both experiments (P
