Description: Corn yield and speed of emergence are important performance indicators for seeders. A field study was conducted investigating the effects of row spacing as well as two different seeders on speed of emergence and yield. Row spacings that were compared included 7.5 inch, 15 inch, 30 inch and paired rows (7.5 inch pairs, 30 inches on centre). The two seeders compared were a twin row Monosem planter and a Salford 522 air drill. Seeding depth and seeded population were intended to be held constant while emergence and yield were investigated. Measurements taken included furrow profile data, seeding depth, emerged population, speed of emergence, and yield. The planter had a wider and shallower average furrow profile than the air drill, leading to seeding depths of 44.8 mm and 52.4 mm, respectively. The planter also had much more uniform seeding depth. Emerged population was found to be 10.2 plants/m2 for the planter and 8.8 plants/m2 for air drill plots. The speed of emergence for planter plots was 2.5 plants/day/m2 compared to 1.6 plants/day/m2 for air drill plots. Yield for the planter and air drill plots was 11032 kg/ha and 10458 kg/ha, respectively. The 15 inch and 7.5 inch plots had higher yields than the 30 inch and paired row plots. Yield had a linear relationship with speed of emergence with an R2 of 0.38. The precise seed placement of the planter was shown to improve yield compared to the air drill.
