Abstract

In intercropping system, the utilization of different nutrients and water is an effective, as well as the risk of failure of cultivated crops is lessened. Field experiments  were conducted at Sakha Experimental Farm Kafer EL-Sheikh Governorate, Egypt during two successive growing seasons 2017/18 and 2018/19 to investigate the effect of intercropping faba bean (CV. Giza 843) with sugar beet (CV. Geloria) grown under water stress and furrow width treatments on growth, yields, quality and some water relations for both crops .Split-plot design was used in the current investigation, the main plots contained three levels of water stress (two, three and four irrigations through the whole growing season in addition sowing irrigation for all treatment),while the sub –plots contained three furrow width(60, 90and 120cm) for faba bean. Sugar beet seeds were sown on the two sides and faba bean seeds were sown on upper ridge at furrow width 120 cm (C). The highest values for growth traits, yields for sugar beet and faba bean intercropping, applied and consumed water were obtained when plants were irrigated four irrigations (I3) and the furrow width 120 cm, but it was recorded the lowest values of water efficiencies. A significant interaction effect was found between the two factors of irrigation and furrow width on most of studied traits. The highest Land Equivalent Ratios (LER; 1.54 and 1.52) and the highest total income (15399.95 and 15030.45 L.E.) were obtained irrigation treatment (I3) and furrow width 120 cm.
