The effects of ventilation and flow of medium in hydroponic tomato culture

, : The effects of ventilation and flow of medium in hydroponic tomato culture. Agriculture and Horticulture 65(11): 1309-1311

In trials in 1990, tomatoes Fukuju were grown in hydroponic culture for 52 days with or without aeration of the medium and with still or flowing nutrient solution. Final plant height was greater with flowing than with still medium, but the effect of aeration was less marked. The shoot:root FW ratio was decreased by flowing medium and tended to decrease with aeration. Oxygen level in the nutrient solution was increased by either aeration or the use of flowing solution.

The aim of this study was to compare scin...

In this study, we used...
