Abstract
The management of Broomrape weed is more difficult than the control of other weeds. Difficulties Broomrape management in containment and elimination of the parasitic weed seed bank in agricultural situations are primarily due to the specialized traits of the parasite that ensure mass production of seeds, their vast dispersal, longevity in the soil and germination in close association with host plants. Therefore, the current research aimed to find new and safe agricultural practices to solve, partially at least, the issues of broomrape in faba bean fields. The study was conducted for two winter seasons of 2019/20 and 2020/21 in naturally infested field with broomrape.in the Experimental Station of Agricultural Production and Research Station, National Research Centre, El Nubaria region, El Behaira Governorate, Egypt. The treatments were mycorrhiza, rice biochar (RB), peanut biochar (PB), rice biochar (RB) + Arbuscular mycorrhizal fungi (AMF), Peanut Biochar (PB) + Arbuscular mycorrhizal fungi (AMF), Chelated Calcium, and glyphosate–isopropyl ammonium herbicide and weedy check applied with planting of faba bean. Controlling broomrape where distributed in. experimental design was a strip–plot design with 5 replications. Broomrape number and weight, infested faba bean plants, faba bean agronomic traits and seed nutrient constituents were estimated. Findings clarified that broomrape spikes number and weight and number of faba bean infected plants were higher with Sakha-1 than Misr-3. Among the biochar types and cultivars, Arbuscular mycorrhizal fungi (AMF) inoculation was more effective with peanut straw biochar+ Arbuscular mycorrhizal fungi (AMF) for Misr-3. The distinctive reductions in almost broomrape parameters were obtained with Arbuscular mycorrhizal fungi (AMF) and peanut biochar+ Arbuscular mycorrhizal fungi (AMF) equaling the recommended practice (glyphosate). Sakha-1 or Misr-3 plants treated with Arbuscular mycorrhizal fungi (AMF), rice biochar+ Arbuscular mycorrhizal fungi (AMF) and peanut biochar+ Arbuscular mycorrhizal fungi (AMF) possessed distinctive improvements in pods weight, seed yield and of 100-seed weight of faba bean equaling glyphosate treatment. It could be concluded that Arbuscular mycorrhizal fungi (AMF) alone or with biochar raised the tolerance degree of faba bean genotype against broomrape attacks, hence sustain the productivity, could be achieved through application of biochar inoculated with mycorrhiza. Despite the differences between mycorrhiza-inoculated biochar and glyphosate in broomrape traits and faba bean yield were not significant, the application of inoculated biochar as an eco-friendly tool is advisable for sustaining faba bean cultivation.
