In order to study the effects of chemical and biological fertilizers on soil physical properties, nutrient uptake, nutrient concentration in soil and plant and seed yield and essential oil of fennel (Foeniculum vulgare Miller.), a field experiment was conducted in Agricultural Faculty of Shahid Chamran University in 2011. Trial study was carried out as two-ways factorial in a randomized complete block design (RCBD) with three replications. Chemical fertilizer at three levels (C1=0-0-0 kg/ha NPK, C2=60-60-48 kg/ha NPK and C3=120-120-96 kg/ha NPK) was the first factor, and different biological fertilizers at six levels (B1=control, B2=Biosuperphosphate+Nitroxin, B3=Nitroxin, B4=Biosuperphosphate, B5=Biosulphur and B6=Sugar cane waste compost) were the second factor. Results showed that chemical fertilizer had significant effect on all traits except soil bulk density, soil porosity and essential oil yield. The interaction of chemical fertilizer and biological fertilizer was significant for seed phosphorus, soil bulk density and soil porosity percentage. The highest grain yield (237.66 kg/ha) and essential oil yield (6.46 kg/ha) was found at sugar cane waste compost in combination with 120-120-96 kg/ha NPK and the lowest grain yield (103.15 kg/ha) and essential oil yield (2.63 kg/ha) was obtained at bio sulfur without chemical fertilizer application, respectively. Also, sugar cane waste compost in combination with 120-120-96 kg/ha NPK had the highest grain nitrogen (2.61%) and phosphorus (0.33%), respectively. The lowest was obtained at control treatment. Totally, the results suggested that the sugar cane waste in combination with 60-60-48 kg/ha NPK was the best treatment for fennel cultivation.

To study the effects of different sowing dates and different fertilizing methods (chemical &organic) on yield and amount of active substance of milk thistle (Silybum marianum (L.) Gaerate), a field experiment was done at Agricultural College of Shahid Chamran University during 2009-2010. Experimental design was split plot on RCBD with three replications. Main plot was sowing dates including (14Nov, 1 Dec and 15 Dec) and sub plot was different fertilization levels including: F1: control, F2:100% chemical fertilizer (100-120-150 kg/ha NPK, respectively), F3: %25 organic fertilizer + %75 chemical fertilizer (75-90-112.5 kg/ha NPK + 7.5 ton/ha animal manure), F4: %50 organic fertilizer + %50 chemical Fertilizer (50-60-75 kg/ha NPK + 15 ton/ha animal manure), F5: %75 organic Fertilizer + %25 chemical fertilizer (25-30-37.5 kg/ha NPK + 22.5 ton/ha animal manure), F6: %100 organic fertilizer (30 ton/ha animal manure). Results showed that sowing date had significant effect on the percentage of phenol and flavenoid and the amount of silymarin. Late sowing date (15 dec) decreased grain silymarin content, while the highest percentage of phenol and flavenoid was obtained at 15 Dec. Also, the highest percentage of flavenoid, flavenoid yield and silymarin yield were obtained at 100% chemical fertilizer and integrated fertilizer. In this regard, F2 treatment had no advantage compared to integrated fertilization levels. Also, the highest percentage and yield of phenol was obtained by integrated fertilizer methods. The highest silymarin content was related to F6, and the highest grain antioxidant activity was related to F4 and F6, respectively.
