The computer-operated seeder makes it possible to customize hill spacing and alleywidths without seed mixing between rows and plots. Depending on their requirements, scientists can choose between 1.4 to 38 cm hill spacing.
It uses sub centimeter accurate GPS to ensure straight rows of plots and precise plot lengths. The sowing units follow the contour of the field allowing uniform seeding depth and consequently, uniform emergence, a task which is difficult to achieve with manual seeding. A wide wheel base-tractor is used with the seeder to minimize soil compaction. Only one seed is planted per hill. This is important when scientists have limited number of valuable seeds. Yes, it is bigger than a drum seeder but with proper land preparation and seeding techniques, it is way more efficient and effective.
