The effect of magnetic water and humic acid in growth and production of active ingredients of (Hibiscus sabdariffa L.)

Abstract

This research was conducted in the Lath house of the municipality of Zubaydia District in AL-Suwayra , Wasit governorate from the period 21/3/2010 till 25/10/2010. The goal of the experiment was to determine the effectiveness of magnetic irrigation water in comparison to the normal water, and three concentration of humic acid 1/2 ml/l; 1 ml/l and 2 ml/l in addition to the control treatment and was added four times during the growing season .The ( Bio polar system ) was used with 1000 gauss capacity to magnetize water . The randomized complete book design (R C B D) was used in a factorial arrangement. The least signification difference at 50% level of significant was utilized for mean comparisons, only when treatment effect was evident. Criterion studied include, stem diameter, dry weight of shoot, and leaf size, dry weight of sepals. Active ingredient measured includes β-pinene , α- pinene , citronal , and Hibicine hydrochloride .Results indicated that using magnetic water increased , stem diameter and leaf size , dry weight of vegetative portion ,dry weight of calyx . Magnetic water increased hibicine hydrochloride, citronol, α- pinene and β-pinene. The use of humic acid increased the above mentioned criterion in addition to the weight flowers cup and caused an increase in hibicine hydrochloride and citronol. Results also indicated significant interaction between magnetic water and humic acid and the following characteristic were effected, stem diameter and leaf size as were as vegetative dry weights of calyx, hibicine hydrochloride and citronol.
