Abstract
The main aim of this study is to investigate the possibility of growing mint under three soilless systems. To achieve that, the effect of different soilless systems (aeroponic, hydroponic and substrate systems) and different flow rates (1,1.5 and 2 L h-1 plant-1) on root length, shoot length, stem diameter, fresh and dry weight and nutrients uptake. The results indicated that, the root and shoot length of mint plants grown in aeroponic system were taller than those of hydroponic system and substrate systems. The highest values of root and shoot length (32.06 and 49.02 cm) were found for aeroponic system. The stem diameter of mint plant increases with increasing water flow rate and plant age for all soilless culture. The chlorophyll of mint plants were ranged from 23.07 to 32.48, 24.72 to 33.70 and 24.73 to 34.56, for aeroponic, hydroponic and substrate systems, respectively. The highest value of fresh and dry weight of shoot of mint plants (167.54 and 31.16 g plant-1) were found at aeroponic system and 1.5 L h-1 plant-1, while, the lowest values of fresh and dry weight of shoot of mint plants (130.26 and 22.13 g plant-1) were found at substrate system and 2 L h-1 plant-1. The highest values of the N, P, K, Ca and Mg uptakes were 457.22, 213.76, 463.60, 307.56 and 203.62 mg plant-1, respectively, were found at aeroponic system and 1.5 L h-1 plant-1.
