Abstract
Abstract: This study was carried out in the Autumn season in the plastic houses unit in the department of Horticulture and landscape gardening.Collage of Agriculture,University of Baghdad. Sweet pepper l. Three levels of chemical fertilizer were used(C1,C2,C3), two of the organic(O1,O2) and three types of the biofertilizer (B2,B3,B4) in addition to the control ( B1).Split split plot design was used and irrigated by dripping of 3m3 hr-1. C2O2B4 treatment gave significantly higher root length and diameter and mycorrhizal infection of( 54.82 cm , 3.63mm, 87.50%) respectively in compared with ( 19.26cm, 0.75mm, 2.50%) respectively of C1O1B1 treatment. C2O2B3 and C2O2B4 treatment gave significantly higher root surface area of 482.24 and 478.38 cm2 respectively compared to C1O1B1 treatment which gave the least surface area of 61.16cm2. C3O2B4 treatment gave the highest root dry weight, highest plant length, and highest leave surface area and highest yield of plant of (16.32gm, 57.85cm, 302.91dcm2, and 2.37 Kg.plant-1) respectively compared to C1O1B1 treatment that gave ( 2.07g, 29.63cm, 43.53dcm2, and 0.26Kg.plant-1 ) respectively
