Raising Polianthes tuberosa L. plants by nutrient film technique [electronic resource].

Includes references.

The present work proved the efficlency of using tap water ; of E.C. 1.24 ds/m , total soluble salts 793.6 ppm and containing 8.09 ppm sodium , in preparing Hogland solution for growing tuberose plants (Polianthes tuberosa L.) until flowering in nutrient film technique (NFT). Hogland solution containing ammonium and nitrate as nitrogen forms proved to be better than that containing nitrate form only. Deduced prepared commercial fertilizer formula solution was nearly similar to Hogland solution and resulted in significant enhancing effect than Hogland solution for the vegetative and flowering characters. Using tap water and the commercial fertilizers formula decreased the costs of production , taking in consideration that this technique produced high yields (about 100 spikes/m2).
