In order to investigate the effect of various chelated nano and amino acid fertilizers on grain yield, biological yield, harvest index, oil quantity and quality, starch content and percentage of protein in corn grain, an experiment has been conducted based on a randomized complete block design with 16 treatments and three replications simultaneously in Urmia University and Ajabshir during the 2017 cropping year. Results show that the highest content of starch (80.66%), protein (12.70%), and harvest index (34.60%) related to NPK nano-chelate fertilizer treatment, the highest amount of oil (4.98%), grain yield (16596 kg / ha), and biological yield (52393 kg / ha) are related to iron amino chelate and the highest weight of 100 grains (36.34 g) is related to zinc nano chelate, which are 22.03%, 30.92%, 23.66%, 25.44%, 50.81%, 33.15%, and 24.65% more than the control treatment, respectively. The use of magnesium amino chelate, micro-mix amino chelate, potassium amino chelate, and NPK nano-chelate increase the amount of saturated fatty acids more than other fertilizers, but Copper nano-chelate, phosphorus amino-chelate, pigeon, and salicylic acid fertilizers increase the content of unsaturated fatty acids by 16.04%, 16.35%, 17.44%, and 20.29%, respectively, compared to the control treatment.

Evaluation the effect of drought stress and foliar nutrition of iron nano-chelate and fulvic acid on grain yield and fatty acids composition in seed oil of two sesame cultivars was conducted during a factorial split-plot experiment based on randomized complete block design with three replicates in 2017 in the Research Farm Shahed University of Tehran. The experimental factors included drought stress in three levels: full irrigation as control, irrigation up to 50% seed ripping, and flowering, as well as four treatments of foliar nutrition by iron nano-chelate and fulvic acid in Dashtestan and Halil cultivars. The results showed that the drought stress reduced grain yield and also, seed oil content. The highest grain yield was observed in full irrigation (2303.3 kg/ha) and the co-application of iron nano-chelate and fulvic acid (2246.4 kg/ha). Halil cultivar had the highest mean of the total number of capsules (81.19), number of seeds per plant (4786.1), 1000-grain weight (3.21 g), grain yield (2172.7 kg/ha), and biological yield (13534.6 kg/ha) in compared with Dashtestan. The highest oil and protein yield were observed in full irrigation and irrigation up to 50% seed ripping. Irrigation cut off at 50% flowering and seed ripping had the highest oleic and linoleic fatty acids compared to the control treatment, but the highest palmitic and stearic fatty acids were obtained in full irrigation treatment (10.86 and 10.73%, respectively). Halil and Dashtestan cultivars had the highest unsaturated and saturated fatty acids, respectively.

In order to evaluate the seed yield and qualitative traits and oil in some winter rapeseed (Brassica napus L.) varieties as affected by micronutrient elements, this experiment was performed during 2011 - 2012 cropping seasons as split plot arrangement in randomized complete block design with three replications, in Arak, Iran. Micronutrient fertilizers including of Zero as check, Fe, Zn, Mn, Fe + Zn, Fe + Mn, Zn + Mn, Fe + Zn + Mn as main plot and rapeseed varieties including of Zarfam, Okapi, Modena and Licord as sub plot, comprised the experimental factors. The results showed that Okapi variety had the highest seed yield as affected by check (4194 kg/ha) and Zn + Mn (4011 kg/ha) treatments, respectively. In this research, Licord variety showed the highest seed content of Zinc at check and Fe + Mn treatments. The greatest seed content of copper obtained in Modena variety and Fe + Zn treatment. The greatest seed content of iron was shown in Modena vatiety, Fe and Fe + Zn treatments. Also, the highest seed content of manganese obtained in Modena variety and Zn + Mn treatment. In general, Zn + Mn treatment increased seed yield and oleic acid in Okapi variety. Hence, these treatments could be recommendable in Arak region and similar agroclimatic conditions.
