Abstract
The Experiment was carried out in one of the farms in the College of Technology Musayyib during the growing season 2007-2008 to study the effect of two kinds of soils of the region (sandy soil from the shoulder of the river and loamy soil from a field experiment) and eight agricultural media is (1 - loamy or sandy soil (compared) 2 – loamy or sandy soil added to sawdust + corn residue (1:1:2) 3 - loamy or sandy soil added to residue of cows + Poultry (1:1:2) 4 - loamy or sandy soil added to sawdust + residue of cows (1:1: 2) 5 loamy or sandy soil added to sawdust + Poultry waste (1:1:2) 6 - loamy or sandy soil added to residu of corn + cows (1:1:2) 7 - loamy or sandy soil added to corn residue + Poultry waste (1:1:2) 8 - loamy or sandy soil added to the four residues (1:1:1:1:4). During the vegetative growth stages, in hybrid tomato c.v hayber ,French origin. Complete CRBD with three replications was used and the means were compared by L.S.D test at 0.05% . Results showed that: The loamy soil have been more effected to improved in their physical and chemical characteristics in all the studied media ( porosity, and average diameter measured and the percentage of available water, cationic exchange and the proportion of organic matter, pH, and increased salinity of the medium ) during all periods of the experiment (30, 90 and 150 days from transplanting). The results show for the media containing all types of waste were the best improving these properties, followed by media containing animal waste, and media containing animal waste mixed with plant waste.
