Abstract:
Simultaneous planting and final ridge formation using a deeper planting depth is necessary in order to achieve good soil cover of tubers and fewer green tubers. Three planting depths were used: planting depth 1 (the shallowest), planting depth 2 (the medium), and planting depth 3 (the deepest). Planting depth 3 led to the largest minimum distance of tubers from the ridge side, and the smallest percentage of tubers in the upper layer of the ridge (0 to 5 cm). However, the highest yield and percentage of green tubers and the smallest marketable yield occurred at the shallowest planting depth (1). The tuber cluster covers 80 to 90% of the area of the ellipse. Empty spaces surrounding the tuber cluster in the ridge also affect the percentage of green tubers in the ridge, which predominantly occur at planting depth 3 and are the rarest at planting depth 1.
