Abstract
Ten field experiments were conducted under naturally broomrape infested soils at the Experimental and Research Station, Faculty of Agriculture Cairo University, Giza, Egypt during 2018/2019 and 2019/2020 winter seasons. The main objectives are to elucidate the performance and phenotypic as well as genotypic variations of recent Egyptian faba bean varieties in reaction to Orobanche infestation under variable environmental conditions as sowing dates. The searching for the proper faba bean genotype/s that resist/tolerate Orobanche under wide range of environmental conditions is aimed also. The utilization of recommended dosage, i.e. 160 g of a.i/ha herbicidal treatment of Glyphosate (48%) of N-phosphono methyl glycine used in two splits each added with 480 L water starting as foliar application starting at 25% flowering of faba bean plants compared to untreated plots was targeted to explore their validity under different environments . During each season, five trials were carried out, i.e. at five planting dates starting in October, 28th 2018 and October, 17th 2019 in 1st and 2nd season, respectively. Ten faba bean genotypes were used in each trial: Cairo 4, Cairo 5, Cairo 25, Cairo 30 and Cairo 49 obtained from (Agronomy Department, Faculty of Agriculture; Cairo University), Misr 3, Giza 429, Giza 843 and Nubaria 3 from Food Legumes Section (Field Crops Research Institute, ARC) and Mariot 2 from Desert Research Center (Egyptian Ministry of Agriculture and Land Reclamation).It could be concluded that the environmental conditions beared from different sowing dates has manipulated the performance of faba beans yield and attributes as well as the broomrape reactions
