Abstract :

Two pot experiments were carried out in the wire house, National Research Centre–, Dokki, Egypt to evaluate the effect of cobalt on Moringa growth, yield quantity and quality.Seeds of Moringa olifera were sown in 8 August during 2012 and 2013 Seasons. Seedlings of Moringa Olifera (at the true leaves) irrigated once with cobalt concentrations; 0.0, 2.5, 5.0, 7.5, 10.0, 12.5 and 15.0 ppm. Cobalt sulphate salt was used to enrich the soil with cobalt. All treatments were 5 replicates and arranged in a randomized complete block design. Irrigation with tap water was practiced to keep soil almost at field capacity for 120 days. After 60 days from sowing, plants were harvest (10 cm above soil surface). Plants were harvested after 45 days from first harvest, and then plants re–harvested third harvest after 45 days from second harvest. The obtained results are summarized in the following: • All cobalt treatments significantly increased growth and yield parameters, minerals composition and chemical constituents compared with untreated plants. • Cobalt at 10 ppm resulted the superior growth, yield quantity and quality of Moringa olifera herb. • Increasing cobalt level in plant media above 10 ppm the promotive effect of cobalt was reduced.
