Abstract

The present study was conducted under naturally infested soils with broomrape (Orobanche crenata Forsk.), at El-Gemmeiza Research Station, Agricultural Research Center, Gharbia governorate, Egypt during 2022/2023 and 2023/2024 seasons. The aim of this study was to compare the using of four faba bean cultivars (Giza 429- Misr 1- Giza 716- Giza 3) under three densities of garlic relay intercropping with two applications of Round up star on controlling broomrape and improvement of faba bean productivity and quality. A split plot design was used with three replicates; the main plots were assigned to cultivars, while the subplots were assigned to garlic densities as single row at 150 kg, two rows at 300 kg and three rows at 450 kg/feddan, roundup herbicide at 75 cm/feddan twice applications, hand pulling twice and untreated control. The highest significant reduction in broomrape infestation which was reflected in the greatest increase in faba bean yield and components as well as improvements in protein, proline and carbohydrate contents together with the highest net return and benefit/cost ratio for seed and straw yields was obtained by the cultivars Giza 429 and Misr 1 when treated with Round up star at 75 cm/feddan at the flowering stage and again after 21days interval. The next best results were achieved by these two cultivars when grown under garlic intercropping at the previous three densities gradually.
