The main factors affecting non-cultivated NIT system were studied. These factors are: slope of the channel of the nutrient solution and discharge of the feeding pump (were taken as variables) and• depth of the nutrient solution and speed of the nutrient solution (were measured). Two groups of graphs were plotted which may enable determining, under certain conditions, slope of the channel of the nutrient solution and speed of the nutrient solution in terms of a certain discharge of the feeding pump and a depth of the nutrient solution based on this study results as well as experience with the cultivated plant. This research needs subsequent studies on which the procedure of this research may be applied on cultivated NFT UR - http://nile.enal.sci.eg/EALE/2015/MJAE/3215/4/1709.pdf ER -
