Abstract
The prediction that very high seed yields of dry beans (Phaseolus vulgaris L.) would be produced by the delayed transplanting of large plants has been tested in a factorial experiment with four dates of transplanting and eight plant populations. There were significant differences in yield between transplanting dates and between population densities, and there was a significant date-density interaction. At low plant densities (up to about 30 plants m−2) the three transplanted treatments yielded less than the hand-sown controls, and late transplanting yielded less than early. At the highest density the situation was reversed; all three transplanted treatments out-yielded the controls and late transplanting tended to out-yield plants transplanted early. The biggest yield was 340 g seed m−2 from a transplanted crop grown at 35 plants m−2. The data on yield fitted a modified rectangular hyperbola of the form where y is yield per unit area, p is the number of plants per unit area, t is the number of days between sowing and transplanting, and Bo, n, m, and p are arbitrary parameters. This equation accounted for 91 per cent of the variation in yield with t and p. It is suggested that late transplanting had adverse effects, due to transplanting ‘shock’ and which were most marked at low plant densities; and beneficial effects, ascribable to an effect on plant ‘plasticity’, which were most marked at high plant densities. Possible physiological mechanisms of these effects are discussed.
