To investigate the effect of iron and zinc chelates on some quantitative and qualitative characteristics of medicinal plant black cumin (Nigella sativa L.), a factorial experiment was conducted in a randomized complete block design with three replications in two areas (the research farm of 1- Gonbad Kavous University in Golestan province and 2- Agriculture Faculty of Tarbiat Modares University in Tehran province). Experimental treatments included control )spray with pure water), and separate foliar spray of iron: iron nano-chelate at two levels of 1.5 and 4 per 1000 and iron chelate at 3 per 1000 and zinc: zinc nano-chelate at two levels of 1.5 and 3 per 1000 and zinc chelate at 3 per 1000. The treatments were applied in the 8-10 leaf stage and at the time of filling the capsules. The application of nano forms of iron and zinc chelates compared to the common forms had a significant relationship with yield and yield components and qualitative characteristics and increased them. Concentrations of 4 per 1000 of iron nano-chelate and 3 per 1000 of zinc nano-chelate caused the highest increase in seed yield (217.47 g m-2 in Gonbad and 288.67 g m-2 in Tehran), biological yield (582 g m-2 in Gonbad and 337.2 g m-2 in Tehran), harvest index (37.43% in Gonbad and 76.46% in Tehran), and oil percentage and yield. The highest numerical values for cell leakage (57.70 µmol g-1FW in Gonbad and 64.72 µmol g-1FW in Tehran) and prolin (13.40 mg g-1FW in Gonbad and 11.51 mg g-1FW in Tehran) were related to iron and zinc chelate treatments (common forms). Based on the results, the application of the nano form of iron and zinc, even at low concentrations, could positively affect the quantitative and qualitative yield.

This research was aimed to investigate the effects of foliar application of micronutrients on some morphological traits in fenugreek (Trigonella foenum-graecum L.). The study was conducted in a randomized complete block design with eight treatments and three replications in 2012 at the research farm of Agriculture and Natural Resources of West Azarbaijan Research Station. Treatments included: control (no spray), foliar application of iron, zinc, manganese, iron + zinc, iron + manganese, zinc + manganese, iron + zinc + manganese. These elements were provided from iron sulfate, zinc sulfate and manganese sulfate and were applied at pre-flowering stage. Results indicated that there was statistically significant difference between control and spraying of micronutrient elements. In addition, results showed that spraying of micronutrient elements significantly affected plant height, number of lateral branches, number of pods per plant, number of grain per pod and fresh forage yield. Iron + zinc+ manganese spraying was superior compared to the other spraying treatments. Thus, results showed that the use of micronutrients could improve the morphological characteristics of Fenugreek.

This research was aimed to investigate the effects of different levels of manure, iron and zinc fertilizers on yield, yield components and essential oil percentage of cumin (Cuminum cyminum L.) in Jiroft during 2012-2013. The study was performed as factorial in a randomized complete blocks design with three factors and 18 treatments in three replications. Manure at two levels of zero and 150 ton ha-1, zinc sulfate at three levels of 0, 25, and 40 kg ha-1and iron fertilizer at three levels of 0, 2.5, and 5 kgha-1 were applied. In this study, plant responses consisted of yield, shoot dry weight, plant height, number of seeds per plant, number of umbels, and 1000-seed weight. Results showed that manure, iron and zinc fertilizers at different levels affected shoot dry weight, yield, number of seeds per plant, number of umbels, plant height, 1000-seed weight, and essential oil percentage significantly at 1% level of significance. In addition, the interaction effects of manure and iron and zinc fertilizers were significant on shoot dry weight, yield, number of seeds per plant, and 1000-seed weight. According to the obtained results, a combined treatment of manure (15 ton ha-1), zinc sulfate (25 kg ha-1) and iron fertilizer (5kg ha-1) could be recommended to enhance the yield and yield components of cumin in Jiroft.

To evaluate the effects of salinity in the presence and absence of iron on growth, photosynthesis pigments and electrophoresis bands in two chamomiles, an experiment was conducted as completely randomized factorial design with three replicates at university of Zabol in 2009. The treatments were two genuses of chamomile (German and Roman chamomile), four levels of salinity (0, 50, 100 and 150 mM NaCl) and two levels of iron (0 and 100 μmol). Results showed that, by increasing salinity from 0 to 150 mM NaCl, fresh and dry weight of shoot were reduced but root dry weight was added. At the absence of iron treatment, fresh and dry weight of both shoot and root were reduced in two genus of chamomile. Salinity decreased the amount of two pigments chlorophyll a and b and increased the amount of carotenoids. At the absence of iron, the amount of chlorophyll ‘a’ (32/9) and chlorophyll ‘b’ (35/5) percent decreased in comparison to control treatment (100 μmol). Unlike chlorophyll, at the absence of iron treatment, the amount of carotenoid was added. At the salinity stress from 0 to 150 mM, many protein bands in Roman chamomile were excluded. However, at the levels of 50 and 100 mM NaCl, a 42 KDa fraction band in this material was synthesized, but at the highest level of salinity (150 mM NaCl) many of their bands were removed. Presumably, the 150 mM NaCl is out of tolerance of Roman chamomile genotype. In this study, at the German chamomile genotype under salinity and iron deficiency no bonds were not removed and two bands 14 and 18 KDa were appeared.
