| Abstract | ||||
| The present investigation was conducted at Ismailia Agric. Res. Station Farm, Ismailia Governorate Egypt, during : 2004 / 05 and 2005 / 06 seasons, to study the influence of sprinkler irrigation intervals (1, 2, 3 days), row distances (15 and 20 cm) and Agar Agar as soil conditioner on the yield and yield components as well as their interaction on yield of new flax variety Giza 10 and its attributes. A split - split plot design with three replication was used. The results could be summarized as follows: 1- Irrigation intervals (I) had significant effect on plant height cm, technical stem length, straw yield / plant, number of capsules / plant, seed yield /plant, seed yield fad, fiber yield / plant, fiber yield / fad, and straw yield fad ton in both seasons whereas technical stem length did not reach the level of significance in the first season. The highest values of this characters were obtained by three days as sprinkler irrigation intervals. 2 – Row distances (D) 20 cm. produced the highest values of straw yield / plant, number of capsules / plant and seed yield / plant, while the highest plant height, technical stem length, seed yield / fad. , fiber yield / plant and per faddan and straw yield / fad were produced by row spacing 15 cm. in both seasons. 3 – Agar Agar as soil conditioner (C) significantly affected all characters under study in both seasons compared with control. 4 – All interaction between the studied factors were not significant except IxC for plant height, technical stem length, number of capsules / plant, seed yield / plant, seed yield / fad, fiber yield / plant and fiber yield / fad. as well as DxC for plant height, fiber yield / fad and straw yield / fad Also IxD for number of capsules / plant, seed yield/plant, seed yield /fad and fiber yield /plant finally IxDxC for number of capsules /plant, fiber yield/ plant and per faddan. It can be concluded that under sandy soil condition its recommended to cultivate flax crop and irrigated every three days for two hour time instead two and one days with 15 cm as row spacing under soil conditioner (Agar Agar) to availability water and increased nutrient in root zoon to obtained highest yield of straw and seed and its attributes | ||||
