| Abstract | ||
| The experiment was conducted in the College of Science experimental field / University of Diyala , during the spring season 2006 on maize plant (Zea mays L.)IPA (3003) in Loamy sand soil . The experiment was carried out using a Randomized Complete Block Design (RCBD) . The soil was sterilized by Basamid Pesticide (Fungal - Nematodal) . Eight treatments combination for the experiment was applied through using of two levels of the first factor (Humic acid) and four levels of the second factor (Fungal inoculation). Humic acid levels were (with and without supplementation), Where as Fungal inoculation levels were (no fungal ; Glomusmosseae ; Trichodermaharzianumand Glomus + Trichodermacombination). Three replicates for each treatment combination were used 24 experimental units for the experiment). To investigate the effects of Humic acid and Fungal inoculation and their interaction at a sterile soil on the growth and yield characteristics of maize Plants .Plant samples were taken after 30 days from sowing, at flowering and harvesting stages. The results obtained can be summarized as follows :- 1 - The supplementation of Humic acid caused a significant increase in plant height after 30 days from sowing and at harvesting stage , shoot dry weights, the percentage of mycorrhiza infection , grain yield , weight of 100 grain. 2 - Inoculation with V.A.M Fungus appeared to have significantly increased in all signs of plant growth. 3 - The combined treatment of both, the Fungus G. mosseae and T. harzianum showed a significant effects on all signs of plant growth. 4 - The treatments combination of Humic acid supplementation with the two fungus G. mosseae and T. harzianum showed a significant increase in plant height and the percentage of mycorrhiza infection after 30 days from sowing and at harvesting stage, the weight of shoot dry and 100 grain , as compared with other treatments combination. Besides, the superiority of supplementing Humic acid with the Inoculum G. mosseae regarding plant height and the percentage of mycorrhiza infection at flowering stage , grain yield and leaf area . But, there was anon- significant difference between the two treatment. | ||
