Abstract

A faba beans (Vicia faba L.) as one of its most significant field crops due to their great nutritional value for both humans and animals. However, they were attacked from the roots by parasitic weed plants like broomrape (Orobanche crenata F.), which completely destroys their host due to their rapid development and deficiency in chlorophyll, a necessary component for photosynthesis. This study was carried out during winter seasons 2020/2021 and 2022/2023 at naturally infested field in Qaha Research Station, Plant Protection Research Institute, Qalyubia Governorate, Egypt. The goals of study was to applicate an alternative strategy of crop protection against broomrape weed control by two chemical treatments as indole acetic acid and salicylic acid to enhance systemic defense responses of faba bean plant. And allelochemical treatments by using trap crops as flax and radish with main plant that stimulate suicidal germination of broomrape in their fields. The obtained results of chemical control illustrated that biochemical assay conducted an increasing in total chlorophyll, total phenols and peroxidase activity during two seasons for IAA and SA respectively. Compared with allelochemical control conducted that increasing in total chlorophyll, total phenols for flax and radish respectively. Increasing of total protein, prolin, peroxidase enzyme for flax during two seasons respectively. Furthermore, all treatments could be used an integrated control strategies to increase faba bean growth vegetative and decrease the number of spikes per m2 and spikes dry weight per m2 by increasing of broomrape weed control during both seasons.
