Abstract
SummaryOnion seed cv White Spanish was hand-sown in a square arrangement at 178, 400, 625, 816, 1 111 and 1600 plants m−2. Increases in plant density resulted in reductions in plant size, mean bulb weight, plant fresh and dry weights, number of leaves, cumulative leaf length and time to maturity, but did not affect soluble solids content, the bulb ratio or the percentage dry matter per plant. Density had no effect on bulb uniformity but could be used to determine the distribution of size grades within the crop. Total and pickling-bulb yields gave overturning type relationships with plant density and were highest at 400 and 625 plants m−2 respectively. The practical implications of these results are discussed.
