Abstract
The identification of suitable nutrient composition and concentrations for potted miniature rose production in Japan has not been addressed.
In this study, we propose a suitable phosphorus (P) concentration for potted miniature rose cultivation based on a study on plant dry weight, P uptake and residual nitrogen (N) in pot soil.
Three P treatments, 10, 20 and 40 mg/L were evaluated.
Dry weight and P content in the shoots (leaves plus stems) were highest in the 40 mg/L P treatment.
In addition, total N and NO3-N in substrate soil solution were lowest in this treatment.
Therefore, we concluded that 40 mg/L was a suitable P in nutrient solution concentration for miniature rose production.
