Résumé
The disposal of Olive Mill by-products (OMP) is becoming of increasing concern to the environments in the Mediterranean area, where two million tons of olive fruit are processed every year generating hundred of thousand tons of olive mill solid waste (Jift), and million of gallons of olive mill wastewater (Zebar). However, that the organic matter may be considered as a potential soil fertilizer. Green house experiments, and field trial were carried out during the 1999/2000 growing season, at Jordan University of Science and Technology agricultural station. Objective of this study was to investigate the effect of different levels of OMP soil treatments on growth and nutritional status of wheat (Triticum aestivium L.), barley (Hordum vulgare L.), lentil (Lens culinaris Med.), and faba bean (Vicia faba L.). Three levels of Jift and zebar soil treatments, beside to chemical fertilizer and animal manure were assigned randomly in a randomized complete block design, with three replications. Jift soil treatments at ratio 1:12, and treated zebar at rate 4L m-2 was only showed increased grain yield and biological yield of cereal crops. Earlier heading date was observed for wheat in the jift ratio 1:12, and zebar rate 2L m-2 treatments, 58 and 57 days respectively, compared to untreated control. Chemical analysis for inorganic nutrient elements in the foliage of crops revealed that both treatments, jift and zebar, resulted into increased nitrogen content, potassium, zinc, and iron concentration. But, there was no significant difference in phosphorus concentration of treated plants compared to the control. There was no significant difference in harvest index between treated plants and untreated control of cereals and legumes crops. Phonological traits of cereal and legumes were sensitive to high rate of treated jift and zebar in soil. Olive mill by-products, jift and zebar are recommended to used as soil amendments as a pre-plant treatments for the tolerant faba bean crop and could be used at low rates (1 : 12) in case of cereals as those crops showed considerable levels of sensitivity to these products.
