| Abstract | ||
| The present investigation was carried out at Giza Experimental Station, A.R.C. (clay loam soil) and at Tag EI-Ezz Research Station (moderately saline soil) during the two growing seasons of 2000/2001 and 2001/2002 to study the effect of biofertilizer (phosphorein, 10 glkg seeds), micronutrients (cotngein, 15 glkg seeds and foliafeed C, 0.7 g/l) and gibberellin (GA3, 0.1 g/I) on yield and productivity as well as vitamin E of oil seeds in flax plant grown under clay loam and moderately saline soil conditions. The obtained results indicated that clay loam soil surpassed moderately saline soil in flax yield (seed, straw, fiber yield and its components). Phosphorein significantly increased seed, straw and fiber yield and its components. Also, phosphorein with recommended dose of phosphorus fertilizer (at the rate of 100 kg PzOslfed.) (PzOs) surpassed the increase by adding phosphorein combined with half dose of P20S (1/2 P20s). There are significant increases in stem diameter and fiber fineness due to the interaction between soil type and phosphorein biofertilizer combined with recommended or half dose of P20S. Moreover, there was significant increase in seed, straw, fiber yield and its components of flax plants grown under clay loam and moderately saline soil by using cotngein or foliafeed C application as micronutrients compounds. Cotngein seed coating application surpassed foliafeed C foliar application in seed, straw, fiber yield/fed. Using GA3 as foliar application at the rate of 100 ppm increased seed, straw, oil and fiber yield and its components. Vitamin E (a-tocopherol) concentration of the oil seeds increased in the plants grown under moderately saline soil when compared with those grown under clay loam soil. a- tocopherol concentration in linseed oil increase significantly by flax seeds treated with phosphorein, cotngein, foliafeed C or GA3 application when compared with control- untreated plants. | ||
