Influence of in-row distances on potato (Solanum tuberosum) seed yield and economic feasibility

Bielinski M. Santos, James P. Gilreath, Persio R. Rodriguez


Field studies were conducted in the Dominican Republic to determine the effect of in-row spacing on 'Granola' potato (Solanum tuberosum L.) seed yield and economic feasibility. In vitro seedlings were transplanted on raised beds with in-row spacing of 0.20, 0.25, 0.30, 0.35, and 0.40 m, and 0.75 m between planting beds. The results indicated that inrow distances of 0.20 and 0.25 m increased total tuber number and weight, and tuber weight per plant. The marginal return rate increased by 13% when in-row distance decreased from 0.35 to 0.25 m.
