USING WATER EXTRACTS OF SOME ALLELOPATHIC PLANTS ACCOMPANIED WITH A REDUCED RATE OF GLYPHOSATE FOR CONTROLLING BROOMRAPE IN FABA BEAN

A field experiment was conducted on an Orobanche naturally infested soil at Sakha Agricultural Research Station - Kafr El Sheikh, in 2017/2018 and 2018/2019 seasons aiming combating crenata faba bean through using waterextracts of fenugreek, coriander sorghum crops, each a concentration 10% weight/volume rate 20 litres/fed mixed with glyphosate (48%) reduced (40cm3/fed) compared to the recommended same herbicide (75 cm3/fed).Treatments were foliarly applied twice 50 70 days after sowing. Two beanOrobanche tolerant cultivars (Misr 1 Giza 843) susceptible one (Sakha 1) used this study. The laid out split plot design three replications. randomly devoted main plots while broomrape control treatments arranged sub plots. results showed significant reductions spikes number weight harvest due all no differences among them. Misr 843 inferior Sakha1 cultivar spikes/m2, but they superior yield its components. Therefore, foliar application either or plant extracts as donor allelopathy w / v litres glyphosateherbicide 40 cm3 fed sowing can help controlling improve especially for genotypes.
