| Abstract | ||||
| Two field experiments were carried out during 2004/2005 and 2005/2006 seasons at Gemrniza Agriculture Research Station, El-Gharbia Govemorate to study the effect of two previous crops (Maize and Rice), five tillage systems (Chisel plough (two passes), Chisel plough (one pass), Rotary plough, Chisel plough once followed by rotary plough and no tillage) and three seeding rates (70, 80 and 90 kg seed/fed) on yield components, technological characteristics of Sakha flax variety and water consumption. The results of the present investigation indicated that: Sowing flax after Maize (C1) had significant increase than sowing after Rice (C2) in seedling emergence, plant height, technical length, straw yieldlfed, fiber yieldlfed, fiber length, fiber percentage and fiber fineness. Chisel plough once followed by rotary plough (t4) surpassed the other tillage systems in all fiber yield and its components except stem diameter and straw yield/plant. Also, surpassed the other tillage systems in all technological characters expect seed oil percentage. On the other hand, no tillage (t5) reached the highest values of stem diameter, straw yield/plant and all seed yield and ts components. The statistical analysis showed significant differences of seed and fiber yield between all seed-bed preparation systems, all previous crop and seed rate. In general, it can be stated that raising flax fiber and seed yield can be achieved by using chisel plough two pass at sowing rate 80 kg seed / fed when the previous crop was maize. While, raising fiber and seed yield can be achieved by using chisel plough once followed by rotary plough at sowing rate 90 kg seed / fed. | ||||
