Optimal substrate moisture content determined for high-quality bedding plants

15 abril 2015

Scientists determined if irrigation at lower, constant substrate moisture content (SMC) during greenhouse production could acclimate plants for reduced shrinkage during shelf life while conserving irrigation water. A 20 percent SMC treatment produced the best postharvest quality plants resulting from reduced plant height, without detrimental effects on flowering. Results showed controlled irrigation at a lower SMC can conserve water and produce high-quality plants with shelf life equal to that of plants irrigated at high levels.
