Flax serves as a dual-purpose winter crop in Egypt, valued for both seed and fibre. Field evaluations conducted over two winter seasons assessed the effects of three irrigation intervals, set at 25, 35, and 45 days, across three flax cultivars: Sakha 1, Giza 9, and Giza 10. Watering crops every 35 days produced the highest values across all measured yield and quality traits, whereas a 45-day watering interval resulted in the lowest performance. Cultivar performance varied substantially depending on the desired agricultural output. Sakha 1 delivered the highest biological, straw, seed, and oil yields, alongside the highest oil percentage. In contrast, Giza 10 produced superior plant height, fibre length, fibre fineness, and overall fibre yield per unit area. Both cultivars reached their peak performance when irrigated at 35-day intervals.
Flax provides essential raw materials for both vegetable oil and textile manufacturing. In regions facing water management challenges, identifying the exact watering schedule that maximises crop yields prevents waste while ensuring high productivity. Determining which flax varieties excel in seed production versus fibre quality helps farmers select the right cultivar for specific industrial demands.
These findings directly inform farm management practices for commercial growers and agricultural enterprises seeking to optimise flax production for oil extraction or textile fibres. The research is applied and field-tested under local Egyptian conditions, providing an immediate operational guide for selecting Sakha 1 for oil or Giza 10 for fibre using a 35-day irrigation schedule.

<p>Flax is a potential winter crop for Egypt that can be grown for both seed and fiber. The study was conducted during two successive winter seasons of 2013/14 and 2014/15 in the experimental farm of El-Gemmeiza Agricultural Research Station, Agriculture Research Centre, Egypt. The objective of this work was to evaluate the effect of irrigation intervals (25, 35 and 45) on the straw, seed, oil, fiber yields and quality of flax cultivars (Sakha1, Giza9 and Giza10). Irrigation intervals significantly influenced all studied traits except oil percentage. Irrigated flax plants every 35 days gave the maximum values for all traits, while irrigation every 45 days gave the minimum values. In respect to cultivars, significant differences were found in most yield and quality characters. Furthermore, the performance of Sakha 1 cultivar was superior in main stem diameter, biological, straw yields per faddan, seed index, seed, oil yields per faddan and oil percentage. Meanwhile, Giza 10 cultivar highly significantly out yielded Giza9 and Sakha1 in plant height, fiber fineness, fiber length, total fiber percentage and fiber yield per faddan. The interactions between irrigation intervals and flax cultivars were highly significant for all traits. Based on the results, Sakha1 cultivar recorded the maximum values for main stem diameter, biological, straw yields per faddan, seed, oil yields per faddan and oil percentage and Giza 10 recorded the maximum values for plant height, fiber fineness, fiber length, total fiber percentage and fiber yield per faddan under irrigation of plants every 35 days.</p>
