Abstract
To investigate the effect of sulfur (S) and zinc (Zn) fertilizers on yield, fatty acid composition, and micronutrients of two peanut cultivars, a factorial experiment in a randomized complete block design with three replications was conducted in a farm in Guilan province, Astana Ashrafieh city in 2019 and 2020. The effects of S and Zn on peanut seed yield, fatty acids, and micronutrients were significant at the 1% level. The simultaneous application of Zn foliar application at a rate of 2 per thousand and S fertilizer at a rate of 40 kg ha-1 produced the maximum grain yield of the Spanish cultivar (with an average of 5770 kg ha-1). With an average of 5331 kg ha-1, the North Carolina 2 (CN2) cultivar produced the maximum yield when treated with 60 kg ha-1 of S and Zn foliar application at 2 per thousand. In terms of the number of fatty acids that make up the oil structure based on the average of the treatments tested, Oleic acid (56.9% in the Spanish cultivar and 61.1% in the CN2 cultivar) and Linoleic acid (28.6%) had the highest amount. The highest amount of palmitic acid was significantly higher in the treatment of the application of 40 kg ha-1 of S with a foliar application at 2 per thousand Zn (8.8%) and the lowest amount was found in the treatment without S and Zn (7.2%). According to the results of this experiment, both S and Zn factors were effective on most traits, so it is better to use Zn fertilizer if S is used to better absorb this element and can be effective in the growth and development of peanut plants. Therefore, simultaneous use of S fertilizer and Zn foliar application at high levels to improve the quality of fatty acids and grain micronutrients in the Guilan region is recommended.
