Effects of Green Manure Residues on Egyptian Broomrape (Orobanche aegyptiaca Pers.) and Growth Relations in Tomato (Lycopersicon esculentum L.)

In order to evaluate the efficacy of green manure on Egyptian broomrape (Orobanche aegyptiaca. Pers) control and to determin green manure effects on tomato (Lycopersicon esculentum Mill.) growth, a glasshouse experiment was conducted in CRD design with four replications. Treatments consisted of three green manures of wheat (Triticum aestivum L.), barley (Hordeum vulgar L.) and rye (Secale cereal L.) in two levels (50 and 100 biomass return into the soil) and two control treatments of weed free and weed infest treatments. The results showed that among all treatments, the rye manure in both levels (50 and 100 percent return into the soil) reduced significantly the number of broomrape shoot, and nodules on tomato roots; dry weight and the broomrape/tomato dry matter ratio than weed infest treatment. In fact, barley green manure, especially in 100 percent biomass return in many treats, was similar to rye green manure. In spite of reduction in the measured treatments of broomrape, no significant difference was observed among green manure on the dry weight of tomato. Generally, it seems that rye manure in 50 and 100 percent and barley green manure in 100 percent level have the capability to prevent broomrape seed germination and establishment in a better way more research is needed to examine the effects of treatments on tomato growth and quality.
