A study on the effect of pomace olive on wheat growth in the presence of lead

Wheat (Triticum aestivum L.) is a monocot plant belonging to Poaceae family that is the first crop of the world. It is considered the most pivotal agricultural product as the basis of food for human. Indiscriminate use of chemical fertilizers pollutes the environment as well as having adverse effects on human health. Heavy metals area potential hazard to living organisms due to toxicity persistence and bio-accumulation. The use of biofertilizers to supply the nutritional need of the plant is aimed to reduce the use of chemical fertilizers and reducing the effects of heavy metals to overcome these problems. This experiment was conducted with the aim of the study was an investigation of the improvement effect of olive pomace on the adverse effects of chemical fertilizers and also heavy metal. This experiment was factorial based on acompletely randomized design with three replications on morphological and physiological factors at 20-days old seedling stage in wheat (Tritium aestivum L.). The amount of olive pomace in soil was five regarded at treatments (0, 3, 6, 9, 12) percent and the amount of lead heavy metal was (0. 20, 60. 100) %. The result showed that application of olive pomace cause improvement morphological factors: root length, stem length, yield and physiological factors: plant pigments, chlorophyll, carbohydrate, and carotenoids. Root length yield, plant pigments, and carbohydrates showed a significant difference. Between the concentrations studied 3 to 9% range was found appropriate.
