Abstarct: In order to investigate the effects of integrated nutrient Management on yield and yield components of wheat, Ehsan cultivar (N8720), an experiment was conducted in the Mazandaran (Dashtenaze Sari)in crop year 2016-2017. The experiment was performed as a split plot baxsed on randomized complete block design with three replications and tested by LSD test. In this study ,the main plot were different levels of organic matter:1- using organic matter before seed planting, 2- without organic matter using. The subplot were different fertilizer using in nine levels. 1- Check(without fertilizer using). 2- phosphorus using baxsed on soil test, 3- composition of fertilizer baxsed on conventional of region) incloud of 350 kg/ha nitrogen, 125 kg/ha triple super phosphate and 300 kg/ha potassium solphate. 4- bacterial (Pseudomonas fluorescent) inoculation of the seeds. 5- bacterial (Pseudomonas fluorescent) inoculation of the seeds +phosphorus using 25% less than soil test. 6- t 5 + spray nitro-mac. 7- t 5 + spray k-mac. 8- t 5 + spray nitro-mac and k- mak .9- t 5 + spray balance-mac.
The results showed that nitrogen and organic fertilizer use had a positive and significant effect on most traits. Inoculation of Pseudomonas fluorescens bacteria with nutritional management factors increased the studied traits compared to the application of triple superphosphate fertilizer separately. The highest number of tillers was related to organic fertilizer + inoculation seed + P fertilizer application, and the highest leaf area index was related to treatment 8 and non-use of organc fertilizers and chemical fertilizers. The highest amount of potassium and phosphorus in leaf was related to 9 treatments. Grain yield in integrated management increased by 62% compared to control treatment at 8936 kg ha-1
