Abstract

: In order to evaluated the effect of effective microorganism (EM) in different levels of nitrogen on morphologic and biochemical Features of plant and quantity and quality characters of paros strawberry fruit an experiment was conducted on the base of complete randomized block design (RCBD) with three replications at the university of Mohaghegh Ardabili during 2014-15. Treatments were included EM in 4 levels (control, 1, 2 and 3%), EM application methods (foliar and soil application) and nitrogen in 3 levels (50, 100 and 150 net kg per ha urea). In this study has been measured leaf parameters include number of leaves, fresh and dry weight, chlorophyll a,b and total of leaves, root parameters include length, fresh and dry weight, number of runners, flowers and fruits, fruit biochemical and quantity parameters include vitamin c, TSS, TA, length, volume, fresh and dry weight and also yield and storage life of fruits. Analysis of variance indicated that the effective microorganisms and nitrogen has been a significant effect at 0.05 confidence level on all traits except storage life of fruits. According to the results, all traits except fruits TA increased compared to the control due to EM application. The best result was obtained by application of EM 2 and 3 levels. Nitrogen 100 kg/ha level indicated best result in most traits. The highest of leaf area, runner number, fresh and dry weight of leaf in nitrogen 150 kg/ha level, also highest fruits TA in nitrogen 50 kg/ha level has been obtained. According to the results interactions of EM application methods with EM levels has been significant at 0.01 confidence level in fruit number and volume parameters. Based on the results, foliar application of EM 3% has been highest fruits number and soil application of EM 2% has been highest fruits volume.
