| Abstract | ||||
| The present investigation was carried out at Sakha Agricultural Research Station- Kafr Ei-Sheikh during the two growing seasons of 2000(2001 and 200112002. Two field experiments were performed to study the response of flax yield and its components as well as some anatomical characters to seed inoculation with two boi- fertilizers, i.e.. Phosphorine and Nnitrobin under defferen! rates of nitrogen fertilizer i.e., 20, 30. 40 and 50 kg Nlfed. This study was laid out in a split plot design with four I replications. The obtained results could be summarized as follows: Increasing N· level from 20 up to 50 kg N/fed. significantly increased technical stem length. main stem diameter, straw yield/plant. total fiber parcentage asl well as straw and fiber yields/fed. The application of 50 kg N/fed. significantly increased upper branching zone length. number of capsules and seeds/plant. 1000· seed weight. seed yield/plant as well as seed and oil yields/fed. Each increment of applied nitrogen resulted in a significant reduction in seed oil content in both seasons. Increasing N·level from 40 up to 50 kg Nlfed. gave insignificant increase in all these c:aharacters, except straw yield/fed. Results showed gradual and significant increments (or all anatomical characters due to increasing nitrogen level from 20 up to 50 kg Nffed .. except pith area, which decreased significantly with increasing N- level. Seed inoculation with Phosphorine '+ Nitrobin or with Nilrobin alone significantly increased technical stem length, straw yield/plant, straw and fibe yieldsffed. as well as upper branching zone length. number of capsules/plant, seed yield/plant, seed and oil yields/fed. The highest seed oil conlenl was recorded whe~ seed inoculated with Phosphonne. Results showed that all bio- fertilizer treatment significantly Increased all anatomical characters compared with control, except xyle area and xylem area percentage, which reduced signifICantly with bio- fertilizer, On the other hand, blo- fertilizer did not affect pith area character. | ||||
