Abstract

In a study conducted on harmal plant (peganum harmala L. ) at Seds Experimental Station in Beni-Swaif Governorate, three powdered micronutrients formulations and two liquied ones named Wadi (3% Zn, 4.5 Mn and 1.5% Fe), Sahara (5% Zn, 3.5% and 1.7% Fe), Giri (3.8% Zn„ 3.8% Mn and 3.8% Fe), Shiring-Zn (4% Zn, 2.7 Mn and 1.3% Fe) and shiring-Mn (2.8% Zn, 4.2% Mn and 1.4% Fe) respectively, were foliarly applied for three times at the rate of 1.5 g/L. or 1.5 ml/L for the powedered and liquid forms, respectively, starting at flowering and after three week intervals. The results revealed that all the formulations applied increased the fresh and dry weight yields of herb, roots and the whole plant, as well as the alkaloid content in comparison with the control. The "Wadi formulation produced the highest yield of fresh and dry herb and roots. However, it may be considered that the "Shining-Mn" formulation is the favourable one to obtain the highest yield of alkaloids.
