USING DIFFERENT FORMS OF AGRICULTURAL MANAGEMENT TO PRODUCE HENNA (LAWSON/A INERMIS) WITH MINIMIZED POLLUTION UNDER NORTH SINAI CONDITIONS

Abstract

Two field experiments were carried out in two locations (Al-Arish and Al-Shiekh Zowaid), at North Sinai, during the two seasons of 1996 and 1997.

In an attempt, in the first experiment to study the effect of different plant spacing treatments 30,40 and 50 em on the vegetative growth, yield and active . constituents of henna ( Lawsonia inermis L.) plants. While the second one was to study the effect of different fertilization treatments (Bio. fert.), (Organic) (YzBio. fert. + Yz Organic), (Organic + NPK) to minimize heavy metals contamination on the vegetative growth, yield and active constituents of henna (Lawsonia inermis). It could be concluded that, in order to produce the maximum growth, yield from henna leaves and branches with highest content of active constituents as (Lawsone pigment, chlorophyll a, b and carotene, tannins, NPK and carbohydrates) and with allowable range of the following heavy metals as (Ni, Mo, Pb, AI, Se, Cr, Co and Cd) heavy metals, the best treatments were planting plants at on 30cm. distance between plants and using (NPK plus Organic) suitable quantities of fertilizers in different locations.
