Influenced by Inter and Intra Row Spacing at Bako, Western Ethiopia]]>AkassaBikila BelewDerbew DebelaAdugna 62014146An experiment was conducted at Bako Agricultural Research
Centre in the production season of 2011/12 with the purpose of identifying the
best combination of inter and intra row spacings for the optimum production
of potato (Solanum tuberosum L.) seed tuber with marketable size and
good flour quality. Six levels of inter (60, 65, 70, 75, 80 and 85 cm) and three
levels of intra row spacings (20, 30 and 40 cm) were used in 6x3 factorial combination
arranged in a randomized complete block design with three replications. Most
of the observed variables were significantly affected due to the variation in
the treatment combination between inter and intra row spacings. Narrow spacings
shifted seed tuber distribution from larger to the smaller and undesirable tubers
considered from marketable point of view. Though, total yield increased under
narrower spacing conditions, marketable tubers are more promising for encouraging
farmers to continually produce seed tubers. These therefore require relatively
wider spacing to have more number of marketable size tubers. To achieve this,
the study identified 70-75 cm inter and 20-30 cm intra row spacing as the best
spacing combination for optimum yield and good quality potato seed tuber.]]>Hirpa, A., M.P.M. Meuwissen, A. Tesfaye, W.J.M. Lommen, A.O. Lansink, A. Tsegaye and P.C. Struik,201087537552Berga, L., W.
