The Effect of Local Mycorrhiza Isolated and Fertilization on Zea Mays Plant Productivity under Greenhouse Condition

Vesicular Arbuscular mycorrhizal (VAM) fungi play an important role in plant nutrition and plant productivity. The experiment was conducted to examine the effect of indigenous strains of mycorrhizal Fungi and fertilization on maize plant under greenhouse conditions. Soil and root samples of three crop plants (Alfalfa, sugar cane and date palm) were collected from the rhizosphere from depth 0-30cm of two different sites of Sudan(Northern State and Khartoum State). The (VAM) spores were isolated by wet sieving and decanting method. Root dry weights, plant height, root colonization, tissue phosphorus, nitrogen and potassium were significantly affected by the VAM. At P treatment root dry weight was increased by 14.3% compared to the control. Compared with the control treatment, the MD400 treatment increased maize plant height, shoot dry weight, N (%), P (%), and K (%) by 10.1%, and 37.9%, 120%, 150%, and 100% respectively. The MS400 increased, root colonization by 70% relative to control treatment. While color rating increased by N treatment by 53.8%.
