| Abstract | ||
| The main objective of this study is to improve yield, yield components and some technological characters of Giza 7 flax variety under sandy soil of Ismailia Res. Stat., A.R.C., during 1994/1995 and 1995/ 1996 seasons. The treatments were three levels of potassium (24, 36 and 48 kg. K20/fad.) and also three levels of nitrogen (50, 60 and 70 kg. N. / fad.). Results showed that: 1. Straw yield and its related characters significantly increased with increasing potassium levels from 24 up to 48 kg. K20/fad. except fiber fineness which record a significant reduction with increasing potassium levels. The increases in nitrogen levels gave the same trend in relation to straw yield and its related charcters. 2. There was a significant increase by increasing K20 levels in each of number of capsules/plant, number of seeds/capsule, number of seed/plant, seed yield/plant as well as per fad. On the other hand, the high levels of nitrogen (60 and 70 kg. N/fad.) caused a significant increase in seed yield and its related characters except on seed index and oil percentage. 3. The interaction between potassium and nitrogen fertilization was significant regarding to straw, seed yield and their related characters except on number of capsules per plant, seed index and oil percentage. | ||
