In order to evaluate of sowing date and fertilizers, super phosphate triple and zinc sulfate on quantitative yield of annual medics (Medicago scutellata cv. Robinson) in summer cropping, an experiment was conducted as split factorial arranged in completely randomized block design (CRBD) with four replications in crop season 2011-2012 research farm of agriculture faculty of Lorestan university in Khorramabad. The main factor was the sowing date in two level T1: (20th June) and T2: (16th July) and the sub factor was fertilizer super phosphate triple in three levels (P0=0, P1=150 æP2=250 kg.ha-1) and fertilizer zinc sulfate in three levels (Zn1=0, Zn0=50æ Zn2=100 kg.ha-1). The results showed that, triple interaction effects of sowing date, super phosphate triple and zinc fertilizer on the biological yield and 1000 seed weight were significant in 0.01 probable levels. Also triple interaction had significant effect on seed yield and harvest index in 0.05 probable levels. The mean comparison of the triple interactions on the biological yield showed that the highest biological yield (3504.6 kg.ha-1) was obtained in (T2P1Zn1). Therefore it is recommendable treatment in the annual medic to production of dry forage. Also the mean comparison of effects showed that highest seed yield (807.9kg.ha) was obtained in (T2P2Zn1) and lowest seed yield obtained in (T2P1Zn0). Therefore treatment (t2p1zn1) recommendable for production of dry forage and production seed treatment (T2P2Zn1) recommendable.

In order to study the effects of super phosphate triple, water deficit stress and Glomus hoi biological fertilizer on some quantity and quality characteristics of Coriander, this experiment was conducted at Iran Research Institute of Forest and Rangelands in 2006. Field experiment was carried out by a split factorial design with 4 replications. The factors which studied were 0, 16 and 32 kg ha-1 P2O5 (super phosphate triple) and two levels irrigation, irrigation after 30 mm water evaporation from evaporation pan (without stress conditions), irrigation after 60 mm water evaporation (drought stress conditions) and application and non-application of mycorrhiza (Glomus hoi). The results showed that drought stress has significant effect on biological yield, flowering shoot yield and essential oil yield of flowering shoot, root yield, root length, root diameter, essential oil percentage of flowering shoot (α=1%). Highest biological yield, flowering shoot yield, essential oil yield of flowering shoot, root yield and root diameter were achieved without stress conditions and highest essential oil percent of flowering shoot and root length were achieved under stress conditions. Also phosphorus significant effects on biological yield, flowering shoot yield, essential oil yield of flowering shoot, root yield, essential oil percentage of flowering shoot and root length (α=1%) and root diameter were not significantly affected due to phosphorus. Comparison of means showed that highest biological yield, flowering shoot yield, essential oil yield of flowering shoot, root yield and root length were determined under application of 70 kg ha-1 phosphorus and highest essential oil percentage of flowering shoot were achieved under application of 35 kg ha-1 phosphorus. Mycorrhiza significant effect on biological yield, flowering shoot yield, essential oil yield of flowering shoot, root yield (α=1%) and root length (α=5%) and root diameter and essential oil percent of flowering shoot were not significant. Highest biological yield, flowering shoot yield and essential oil yield of flowering shoot, root yield and root length were achieved under application of mycorrhiza. The result showed that quantity and quality characteristics of Coriander increased by mycorrhiza and decreased application of phosphorus.
