Effect of some commercial biofertilizers on growth, seed, volatile oil yield and chemical composition of foeniculum vulgare, mill [electronic resource].

Includes references.

This study was carried out at the Experimental Farm of Fac. Agric., Kafr El-Sheikh, Tanta University, during the two successive seasons of 1998/1999 and 1999/2000, to study the effect of some commercial biofertilizers (biogen, nitroben and serialen) on the vegetative growth, seed yield, volatile oil productivity, and chemical composition of Foeniculum vulgare Mill. The field experiment received 10 m3/fed. organic manure for all treatments, before planting, biofertilizers were utilized at three different dates for each. The results can be summarized as follows: - All biofertilizer treatments increased all studied parameters as plant height, number of leaves/plant, fresh and dry weight of vegetative parts/plant, number of branches/plant, number and weight of umbels/plant, fruits weight/plant and the weight of 100 fruits with significant differences over control in most cases. The best results were obtained from the treatments of serialen 2, biogen 2, biogen 3 and nitro.ben 3. - The different commercial biofertilizers increased volatile oil % in the seeds, volatile oil yield/plant and /fed. The best treatll1ent being serialen 2. - The different commercial biofertilizers increased N, P and K% in the leaves over control with significant differences in most cases. The best results being for the treatments of Serialen 2 and nitroben 3 and serialen 3 in most cases both seasons.
