Objective: In order to evaluate the foliar application of Ca and Zn fertilizers on seed and fatty acids composition of peanut oil (cv. NC2), an experiment was conducted at the Agricultural and Natural Resources Research and Education Center of Guilan Province, Rasht, Iran, during 2018 and 2019 cropping seasons.Methods: This experiment was carried out as a split plot based on randomized complete block design with three replications. Four levels of Zn fertilizer sources, including without Zn application (as control), nano-chelated Zn fertilizer, Zn-EDTA, and Zn sulfate were considered as the main plot and four levels of Ca fertilizer sources, including nano-chelated Ca fertilizer, Ca-EDTA, Ca-chloride and, Ca-nitrate were considered as the sub plot.Results: Foliar application of fertilizers was done before the flowering stage and then repeated with 30-days intervals. The highest seed yield (2790 kg/ha), biological yield (9303 kg/ha), seed oil content (52.3 percent), oil yield (1625 kg/ha), protein yield (673 kg/ha), and oleic unsaturated fatty acid (57.3 percent) was obtained under simultaneous foliar application of Ca and Zn nano-fertilizers and increased the parameters by 29.8, 17.5, 13.4, 38.3, 24.4 and 19.2 percent in comparison to control treatment, respectively.Conclusion: Application of Zn and Ca nano-chelated fertilizers as foliar sprays improved seed and oil yield of peanut under the local conditions. Hence, the Zn and Ca nano-chelated fertilizers could be recommended to enhance the quantitative and qualitative yield of peanut.

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.

In order to evaluate grain yield and fatty acids in peanut (Arachis hypogaea L.) oil as affected by intercropping with corn (Zea mays L.) and different nitrogen rates, an experiment was carried out during 2014-15 cropping season as split plot based on randomized complete block design with three replications in Rasht, Iran. Different rates of nitrogen fertilizer including 0, 100, 200 and 300 kg/ha as main plots and sole cropping of corn and peanut, rows of corn and peanut intercropping at ratio of 1:1, 2:1, 1:2 and 2:2 as sub plots, comprised the experimental factors. The highest corn grain yield (10540 kg/ha) was obtained under the interaction effect between 200 kg N/ha and C6 intercropping system by the ratio of 2:2. The interaction effect between 100 kg N/ha and C5 intercropping system by the ratio of 1:2 showed the greatest peanut grain yield (1786 kg/ha). By increment of nitrogen application, the rate of oleic acid decreased in peanut oil, but the content of linoleic acid enhanced. The highest ratio of oleic acid (27.31%) was observed under corn and peanut intercropping systems at the ratio of 2:1. In general, nitrogen application up to 100 kg/ha and intercropping systems between corn and peanut at the ratio of 2:1 could be recomendable to improve land equivalent ratio and enhancement of grain yield and peanut oil quality under the climatic condition of region.
