A study was conducted to determine the effect of inter and
intra row spacing on potato (Solanum tuberosum L.) seed and ware tuber
emergence and subsequent growth in 2011/12 production season. The experiment
was laid out in a 6x3 factorial combination arranged in a randomized complete
block design with three replications (Six levels of inter: 60, 65, 70, 75, 80
and 85 cm and three levels of intra row spacings: 20, 30 and 40 cm). Most of
the variables collected in this experiment were significantly affected by inter,
intra and/or their interactions except the number of main stem which did not
show any change as the result to change of these treatments. Though most of
the variables considered require wider spacing, it was observed that an indefinite
increase in the space between plants and rows did not result to an increase
in any of the variables apart from extending days to flowering and maturity.
For the optimum emergence and successful growth of potato tubers for both seed
and ware, spacing of 70-75 and 20-30 cm between plants and rows, respectively
were identified as the best combination to be used in the study area. |

An 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. |
