Abstract
SummarySweet peas grown outdoors in pot culture demonstrated a significantly higher fruit-setting rate when high NPKCa levels were maintained in the compost during the flowering period. Doubling the volume of water added to a compost consisting of 75% grit and 25% loam did not reduce the fruit-setting rate. However, with plants in pots a “high-watering” treatment associated with high NPK nutrition increased the succulence, the amount of growth and flower abortion. Low calcium nutrition checked pollen development and reduced fruit-setting.Culture solutions at different osmotic concentrations (achieved by adding sodium sulphate to a nutrient solution) were used to test their effect on the fertility of summer-flowering sweet peas. Flower fertility was equally high whether plants were grown in 0·5 or in 1·8 “atmosphere” solutions.
