The present results indicate that the number and quality of flowers were influenced by different nutrient solutions even so the flowers of all treatments were in a good quality. The analytical results of nutrient solutions at flowering time showed that these solutions had different amounts of nutrients, values of pH, electrical conductivity (EC) and the ratio of NO 3 :NH 4. The results of analytical chemistry indicated that the rainwater contained some amounts of macro and micro elements in forms that plants can absorb and had a good value of pH (6.20) with favorite high ratio of NO 3 :NH 4 making this water to be more efficient for plant growth and development as nutrient solution. The rainwater could be applied as nutrient solution in this system to produce lily flowers in a good quality making this system easier and cheaper way to get into cut lily production. The results show that the NFT hydroponic system was an excellent method to produce lily flowers in 55 days. 2 Basal Salt Mixture, Murashige and Skoog Basal Salt Mixture and White’s Basal Salt) with rock wool cubes as medium with or without removal of flower buds and mother bulb scales. 'Blackout' using rainwater and some common nutrient solutions (Hoagland No. This experiment was carried out to investigate the potential of nutrient film technique (NFT) hydroponic system for flowers and bulbs production of the Asiatic hybrid lily cv.

No significant relationship was found with NO(3)(-):NH(4)(+) ratios for Mg, Zn, and Na. Tissue P, Mo, and Cu increased with increasing NO(3)(-)-N levels up to 50% NO(3)(-)-N supplied, and then decreased. On a dry weight basis, N, B, Fe, and Al concentrations decreased as NO(3)(-)-N levels increased, whereas K, Ca, and Mn concentrations increased. Plants that received increasing amounts of NO(3)(-)-N were greener or had a greater chlorophyll index at the end of the experiment. New rhizome biomass increased with increasing NO(3)(-)-N rates until 50 and 75%, after which, new rhizome biomass decreased. Increasing proportions of NO(3)(-)-N increased total leaf, root, flower, and bottom shoot biomasses. An experiment was conducted to establish an optimum NO(3)(-):NH(4)(+) ratio for oxalis in a hydroponic system. Nitrogen (N)-source ratio (NO(3)(-):NH(4)(+)) effects on growth and development of oxalis have not been investigated previously.
