Two field experiment were conducted at EL-Gemiza Agricultural Research station El- Gharbia Governorate, during 2016/17 and 2017/18 seasons to study the effect of three sowing dates (15th October, 1st November and 15th November) and six intercropping sowing rate of faba bean (Vicia faba) cv. Giza 843 with sugar beet (Beta vulgaris L.) cv. Halawa kws. In all intercropping systems (IS) sugar beet was35000 plant/fad (sugar beet sown one side of bed 120cm width with 1 seed/hill and 20cm hill space) while, faba bean densities differ under all intercropping systems as follows, IS1{70000 faba bean plant/fad (sown one row on the top of sugar beet ridges with two seeds/hill and 10cm hill space)}, IS2 {70000 faba bean plant/fad (sown two rows on the top of sugar beet bed and the bed with one seed/hill and 10cm hill space)}, IS3{(35000 faba bean plants /fad. Sown one row on the top of sugar beet bed with two seeds/hill and 20 cm hill space)}, IS4{35000 faba bean plant/fad (sown two rows on the top of sugar beet ridges with one seed/hill and 20cm hill space)}, IS5{17500 faba bean plant/fad (sown one row on the top of sugar beet ridges with two seeds/hill and 40 cm hill space)} and IS6{17500 faba bean plant/fad (sown two rows on the top of sugar beet ridges with one seeds/hill and 40cm hill space)}.
