Vermicompost, seaweed extracts, and urea impact on fungi numbers in maize rhizosphere soils (Zea mays L.)

This paper aims to test the effect of add a vermicompost, seaweed extracts, and Urea to the soil on the total number of fungi during flowering and complete maturity. Throughout the 2019-2020 fall season, an experiment was conducted on one of the farms in the Nouriya area of Iraq’s Al-Diwaniyah governorate. The experiment, which followed a global trend, used three replications and a fully randomized sector design. The initial factor was the addition of vermicompost fertilizer in three stages (0, 2 and 4 tons h-1), the second factor was the addition of seaweed extract in two levels (0 and 40 kg h−1) denoted by S0 and S1, and the third factor was the addition of urea in three stages (0, 120 and 240 kg N h−1) denoted by U0, U1 and U2, respectively. In maturity of the analyzed descriptions, the tages of vermicompost varied considerably, with level V2 getting the greatest results for the quantity of fungi in the blossoming and complete maturation levels (32.61 103 and 27.40 103 CFU gm−1 dry soil, respectively). The addition of seaweed extracts S1 had a substantial effect on total fungus populations in the blossoming stage (30.66 103 CFU gm−1 dry soil), but not in the complete maturation levels. When U1 Urea was added, the amount of fungus in the blooming stage (26.62 103 CFU gm-1 dry soil) increased dramatically.
