| Abstract: |
A two-years trial was conducted during 2005/2006 and 2006/2007 seasons at the Experimental Farm and in the Laboratory of Horticulture Department, Fac. of Agric., Benha Univ., to evaluate the effect of NPK chemical fertilization at four rates i.e.,(Control, 50 % recommended dose, 75 % recommended dose and 100 % recommended dose) and bio-fertilization at three rates i.e., {without Bio-fertilizer, low rate (500 g Biogein + 500 g phosphorein per fed.) and high rate (1000 g Biogein + 1000 g phosphorein per fed.) } and their combinations on some vegetative growth measurements, seed yield, essential oil and its main components as well as chemical constituents of Foeniculum vulgare, Miller plants. The obtained results indicated that the three rates of NPK mineral applications statistically increased all the studied vegetative growth parameters, seed and oil yield as well as chemical constitunts, with superioriety for the high rate (100 % of recommended dose). Additionally, the two rates of Bio-fertilizer (low and high) succeeded in enhancing all the studied parameters, especially the high rate (1000 g Biogein + 1000 g phosphorein per fed.). Moreovere, all combinations of Bio-fertilizers treatments succeeded in maximizing the effectiveness of NPK mineral fertilization on different vegetative growth traits, seed and oil yield, essential oil productivity and leaf chemical constituent determinations. GLC anallyses revealed the presence each of ±- Pinene , Limonene , Fenchone , Chavicol and Anethole in the volatile oil of seeds and showed that all the tested treatments succeeded in increasing Anethole percent in fennel volatile oil as well as the total compnents of fennel volatile oil when compared with control. Conclusievely, inoculeted the seeds of Foeniculum vulgare with the high rate of Bio-fertilizers (1000 g Biogein + 1000 g phosphorein per fed.) combined with NPK fertilization at 75 or 100 % of the recommended dose, particulary 100 % showed to be the most effective treatments in enhancing all the studied traits. |
