Abstarct: In order to investigate the effect of boron nanoparticle foliar application, biochar application of peanut shells and Azola and inoculation of mycorrhizal fungi on peanut growth and yield, a field experiment was carried out in factorial arrangement baxsed on randomized complete block design with three replications in the year 1395 in Shalaman, Guilan province. The test factors included: 1- Foliar application of nano-fertilizer boron at two levels of zero and three in a thousand. Includes three levels of inactivation, antiseptic application of peanut shell and Azolla biochar. Mycorrhizal fungi with and without inoculation of Glomus mosseae. The extracted biochars were striped in the specified plots and a thin laxyer of soil was poured onto it. The mycorrhizal fungus was placed at the site of sowing and under the seeds in the designated plots. The cultivator used was North Carolina (NC2) or a flower of common cultivars. Foliar application of boron nanodar spray was carried out in one stage (before flowering). The results of the experiment showed that the interaction of soluble boron nanocomponent, unsustainable application and inoculation of mycorrhizal fungus on quantitative traits such as pod yield, dry pod yield, grain yield, seed number per plant, number of pods per plant, Qualitative traits such as nitrogen and phosphorus content and grain protein percentage were significant. According to the comparison of mean values, the yield of dry pod (13230 kg ha-1), grain yield (8953 kg ha-1) ), Number of seeds per plant (160/360) in treatment of boron nano-fertilization, lack of biocavity application and inoculation of mycorrhizal fungus Rosa was in the first place. Foliar spraying of nitrogen fertilizer, Azolla irradiation and inoculation of mycorrhiza showed the highest nitrogen (3.98%) and grain protein (33.87%), which was associated with an increase of 36.2%. Therefore, according to the results of this experiment it can be argued that proper and balanced nutrition management of peanut is effective in producing better and economic performance. Foliar fertilizer application can help to increase the quantitative and qualitative yield of peanut but its use and inoculation of mycorrhiza fungi by maintaining and improving the physical and chemical properties of the soil and maintaining existing resources can increase the quantity and quality of peanut butter.
