Abstract :

 In order to investigation Effect of zinc and boron micronutrient and chelated nano-fertilizersfoliar application on yield and yield components of wheat in Khorramabad region, a factorialexperiment in the form of complete randomized block design with three replications was carriedout in mamolan lorestan region in 2019-2020. In this experiment, two factors were examined.The first factor includes zinc and boron micronutrient foliar application in 3 levels (control,two per thousand and four per thousand) and the second factor includes nano-fertilizer foliarapplication in 4 levels (control, two per thousand, four per thousand and six per thousand).Micro consumption elements and chelate nano-fertilize comprise boron and zinc and microcomplete respectively. The experimental results showed that foliar application of lowconsumption elements (zinc and boron) had positive effect on all the studied traits. Also, foliarapplication of chelate fertilizer showed significant effect on all studied traits except for harvestindex. The highest Seed yield (4442 kg /ha) and 1000 seed weight (38/87 g) were observed intwo per thousand of micronutrients and six per thousand of chelate nano-fertilizer. Due to thepositive effects of micronutrients consuming in increasing the yield of crops and due to thewidespread shortage of these elements in agricultural lands, it is necessary to pay specialattention to these important nutrients in agricultural projects and soil fertility managementprograms and plant nutrition, to be able to harvest more and better quality products in order tomeet the nutritional needs and improve the health of people in the community.
