The following treatments were employed: 1Kalle-Ghochi and Mussili cultivars; 2magnetic water levels at 0, 155, 3000gauss; 3NPK (20:20:20) at o, 250, 500 and 1000ppm; 4B at 0, 5, and 10 and20ppm. The interaction among treatments had highly significant effects on most characteristics. Generally, effect of the two cultivars was varied, while magnetic water treatment was reducing root growth especially with NPK interaction when the highest values for root length, root wet and dry weights (34.00cm, 44.76gm and 36.07gm respectively) were recorded from untreated seedlings, while the interaction of magnetic water levels and NPK had promotive effects on the vegetative parameters. The interaction of B, cultivars and magnetic water levels had significant effects on studied parameters, the most effective dose of B was 20ppm. The interaction among the four studied factors had variable results, the best values as follows: Musilli seedlings irrigated with tap water treated with 500ppm NPK gave the highest values of leaf area and shoot length in different Boron doses (20 and 10 ppm respectively). The highest number of leaves (51.33) was recorded from Kalle-Ghochi seedlings treated with 1500 Gauss magnetic water, 1000ppm NPK and 10ppm Boron. The thickest diameter of seedlings (8.36mm) was measured from Kalle-Ghochi cultivar treating with 3000 Gauss magnetic water and 10ppm Boron. The highest shoot wet and dry weights (59.26gm and 44.13gm respectively) were resulted from Kalle-Ghochi seedlings irrigated with tap water treated with 1000ppm NPK and 20ppm Boron, and the longest root (41.50cm) was recorded with the same above treatment but with no NPK doses. the best chlorophyll content (60.85%) resulted in Kalle-Ghochi seedlings treated with 1500 Gauss magnetic water, 250ppm NPK and 10ppm Boron, while the best RWC (10.70%) was measured from Musilli seedlings irrigated with 3000 Gauss magnetic water, 1000ppm NPK and 5ppm Boron.
