The aims of our study were to compare the effectiveness of different nutrition systems and fungi Piriformospora indica on yield and the concentration of elements in shoot and grain of fennel (Foeniculum Valgare Mill). A field study was conducted in 2009 in the Tehran region and the type of design was a randomized complete block with a factorial arrangement and three replications. Five levels of manure (without organic manure, 100% cattle manure, 100% spent mushroom compost and 50% cattle manure with 50% spent mushroom compost and 100% N) along with two levels of inoculation and not-inoculation of the plant with Piriformospora indica. Results showed that different nutrition systems impacted significantly on yield, dry matter, harvest index and nitrogen concentration of plant and grain. The result also showed that fungi significantly affected all of the measured traits except for the potassium concentration of plant and grain. Also, the interaction effects of fungi ¥nutrition systems was not significant in all measured traits except the harvest index. The result showed that the highest (1559 kg/ha) and the least (632 kg/ha) grain yield was produced in chemical systems Piriformospora indica and fertilization systems respectively

In order to study the effect of Iranian zeolite application namely clinoptilolite in animal manure, on yield and yield component of sunflower under different irrigation regimes, an experiment was conducted during 2005-2006 year, at Research Field of Tarbiat Modares University, Faculty of Agriculture, located at 16 KM Tehran-Karaj Highway, as spilt plot arrangement in randomize complete block design with four replications. Irrigation regimes including: irrigation after consuming 35% of available soil moisture (W1), irrigation after consuming 70% of available soil moisture (W1) that were randomized to the main plot units and subplots were different fertilizer treatments including: providing 100% N of plant requirement from urea chemical fertilizer (F1), providing 60% and 40% N plant requirement from urea chemical fertilizer and animal manure respectively (F2), providing 60% and 40% plant requirement N from urea chemical fertilizer and animal manure compost respectively accompany with zeolite in amount of 5% of animal manure weight (F3), providing 60% and 40% plant requirement N from urea chemical fertilizer and animal manure compost respectively accompany with zeolite in amount of 5% of animal manure weight (F4), providing 60% and 40% plant requirement N from urea chemical fertilizer and animal manure compost respectively accompany with zeolite in amount of 5% of animal manure weight (F5). Result showed that different irrigation regimes and fertilizer levels and their interactions significantly affected on grain yield, oil percent and yield, protein percent, 1000 seed weight, head diameter, grain number in head, final dry matter and leaf chlorophyll content at flowering stage. The highest grain yield was obtained from F4 and F5 treatments in W1 irrigation regime with of 2641.6 and 2602.4 kg/ha respectively. Therefore the best treatments in this experiment were W1F4 and W1F5.
