<strong>Abstract</strong>: Flax (Linum usitatissimum L.) is one of the most important of medicinal plants.
Today‟s products of the flax plant have grown in number and importance, and human consumption
of the flax is increasing rapidly for its food and industrial benefits. A diverse variety of biological
and chemical fertilizers have been used to increase the quality and quantity of crops yield so far. A
field experiment was carried out at the Experimental Station, Faculty of Agriculture, Trbiat Modares
University, during spring season of 2010-2011, to study the effect of some chemical and biological
fertilizers containing macro nutrients (i.e 100 kg/ha Urea as the source of N, 100 kg/ha calcium
super phosphate as the source of P, 150 kg/ha Potassium sulphate as the source of K and 150
kg/ha N.P.K (10-15-10) containing fertilizer as the source of macro complete fertilizer, combination
of 50 kg/ha + 50 ton/ha animal manure and 100 ton/ha animal manure) on yield and its component
of a medicinal flax plant. Results showed that fertilizer treatments had significant effects on all of
the studied characters with the exception of seed germination date and 4-leaf stage. The earliest
and latest flowering date of plants were achieved by applying N.P.K fertilizer and 100 ton/ha
animal manure respectively. The highest plant height in full flowering stage obtained by application
of 100 ton/ha animal manure. Seeding date of plants was also significantly affected by applied
fertilizers; 100 ton/ha animal manure and N.P.K treatment caused latest and earliest seeding date
of plant, respectively. The lowest seed index was obtained in control treatment, whereas N.P.K
fertilizer caused the highest 1000-seed weight. Seed yield, seed oil percentage and oil yield
reached the highest values by adding 150 kg/ha potassium sulphate. Meanwhile oil composition of
seed oils was significantly different because of applying various fertilizers, and linoleic acid had the
highest amount in all of the tested samples. Protein content of seeds reached the highest value
with the application of 100 ton/ha animal manure, while the phosphorus source ranked in the
lowest position.
Key words: Biological fertilizers, flax, Linum usitatissimum, medicinal plants.

<strong>Abstract</strong>: Saffron as an important medicinal plant has an especial position in human‟s health
and food. Irrigation, date of corm harvesting and suspension spraying are the most effective
agents of augmenting Saffron‟s yield. An experiment was conducted to determine the imperative
role of corm‟s size and suspension spraying on saffron‟s yield. Present research was done in
2008-2009 in the experimental field of Shahed University Research Institute. The corms were
picked from 3-year old saffron‟s field and then were planted on our experimental farm. Experiment
was set out in split plot based on completely randomized block designs with triplicate. The main
Factor was in 4 levels including corm harvesting‟s date (30Fr, 4 May, 19 May, 7 Sep), on the other
hand the adjunct factor contained complete fertilizer in 4 levels of density (control, 5%, 7%, 9%).
The complete fertilizer contained (Zn) 5/1%, (K2O) 15%، (P2O5) 8%, (N) 15%. The most important
measured traits were: corm number, main corm number, Main corm dry weight, diameter of main
corm, Dry weight of small corm of each main corm. According to the final results it turned out that
spraying 7% suspension was the best treatment among main factors. On the other case, Dry
