AbstractThis study was conducted in the soil silty clay loam SiCL by using CRD design including: inoculation of corn seeds with seven root extracts, clover node PF, roots remains and clover node Pd, bean node LF, bean node and root remains Ld, bean node with root fungi LMF, bean node and root remains with root fungi LMd, control treatment distilled water CO and four levels of recommendation of fertilizing for nutrients NPK T0 0%, T1 25%, T3 50% and T4 %100.
The results showed a significant increase in plant height and dry weight of plant when inoculation in root extracts for stages first and second, it gave highest value for extract LMF it was 66.58 and 96.10 cm, 60.23 and 143.05 gm plant -1 consecutively. While gave this treatment a significant increase in the concentration of the nitrogen in the vegetative total and available nitrogen in soil, it was 12.83 and 11.54%, 21.73 and 22.53% consecutively, however the results showed a significant increase in numbers rhizobium bacteria within the plant root of the corn for the same treatment, it was increase ratio 455.10 % and significant increase in the density of the bio-community in the soil it was 114.55% for second stage. Regarding recommendation of fertilizing there were a significant increase for T3 to traits in plant height, dry weight, nitrogen of leaves and available nitrogen in soil for both stage it was 52.44% and 36.84%, 41.30% and 58.27%, 14.97 and 7.19 and 30.22 and 27.87% consecutively. While the infection rate of rhizobium bacteria gave a significant increase for T1 it was 6.66% in the second stage, whereas the microbial density gave significant increase for T3 it was 57.69%.
