Growth Responses of Eggplant (Solanum melongena) to Hydrophilic Polymer Mixture Ratio in Growing Medium for Lower Maintenance Urban Agriculture via Green Roofs

Urban Farm DB summary

This study investigated the influence of hydrophilic polymer (HP) mixture ratio on the growth of eggplant (Solanum melongena) for lower maintenance urban agriculture via green roofs. As the hydrophilic polymer mixture ratio increased, the growth index, number of leaves, leaf length, leaf width, and dry weight of shoot and root decreased. Specifically, these values were significantly lower in HP5.0% and HP10.0% treatments compared to the control, and the survival rate was lowest at 56% in the HP10.0% treatment.
