Performance of different sizes of minitubers at different plant spacings in the Terai of Nepal

Minitubers can be used successfully as propagating material in seed production. However, due to their small size, special cultivation techniques are necessary. During the cropping year 1991-92 and 1992-93, the field performance of four sizes of minitubers (1-5 g, 10-10 g, 10-20 g and 20-30 g) was co...

Summary:Minitubers can be used successfully as propagating material in seed production. However, due to their small size, special cultivation techniques are necessary. During the cropping year 1991-92 and 1992-93, the field performance of four sizes of minitubers (1-5 g, 10-10 g, 10-20 g and 20-30 g) was compared to that of the normal-sized tubers (30-50 g) under the plant spacings (70 cm x 25 cm, 60 cm x 20 cm and 50 cm x 15 cm). The results show that foliage ground cover, number of stems per plant and tuber yield were increased with increasing size of minitubers, irrespective of plant spacing. Minitubers planted at 50 x 15 cm gave the highest yield on all seed sizes. The experiment demonstrated that even very small minitubers planted at close spacing can result in worthwhile seed potato production under field condition in Nepal
