In order to investigation the effect of different levels of nitrogen fertilizer on yield of Melissa officinalis L., an experiment was conducted under greenhouse condition in Alborz Research Station in Karaj/Iran in 2003/2004. The research carried out with 6 levels of foliar application of nitrogen using of completely randomized design with three replications. The treatments included 0, 3%, 4.5%, 6%, 7.5 % and 9% nitrogen fertilizer and applied in 3 stages on plant. Results showed that effect of different levels of foliar application on yield was significant. The level of 4.5% had a higher performance (85.8 g/ shoot per plant) to others. Reduction of yield at levels of 7.5% and 9.0% was explained by Micherlich law. Foliar application caused to increase of yield and decreasing of agroecosystem pollution. Foliar application was a suitable approach in sustainable agriculture.

In order to investigate the quantitative changes of essential oil during growth period (vegetative, flowering, after flowering) in Melissa officinalis, samples were collected from Arasbaran and Malekan for two years (2001 and 2002). All samples were dried in laboratory condition and then essential oils were extracted by steam distillation method. The oils were dried over anhydrous sodium sulfate and weighted. Combined analysis of data was done with C.R.D design in 3 replications. Combined analysis of data for Melissa officinalis indicated that effects of year, location and phenology phases weren’t significantly different, but the interaction of (year × location) and (location × year × phenology phases) were significantly different at 1% probability level. Means were grouped using L.S.D (5%). Based on the results of this study, essential oil yield in Malekan was higher at first year at flowering stage (0.197%). Mean of interaction (year × location) showed that oil yield of Melissa officinalis in Malekan at first and second year were respectively (0.108 and 0.080%), and in Arasbaran were (0.035 and 0.018%). The results of the two years showed that the average oil content at first year was more than that at second year.

To investigation of Eenergy efficiency in agroecosystem, a field experiment was carried out on Mellisa officinlais in Alborz research complex in 2004 year. The treatments was 80 kgha-1 nitrogen application in soil and spry application (%2 nitrogen) that was compared to the control treatment (no fertilizers) in complete randomize block design with three replication. In both treatments, the first application was conducted when plant high was 10 cm and second application was after 30 days. The harvest carried out before flowering. The energy efficiency was calculated by a software that had been designed.The results showed that, the spry method was significant (a=%5) to others. In comparison of other treatments, the spry application of nitrogen, increased energy efficiency to 2.14. In the spry method, nitrogen fertilizer reduced. Based on the results, low input Agriculture systems could be introduced for sustainable agriculture.

In order to effects of reduction in nitrogen fertilizer in agroecosystem, a field experiment was carried out on Mellisa officinlais in Alborz research complex in 2004 year. The treatments was 80 kgha-1 nitrogen application in soil and %2 spry application that was compared to the control treatment (no fertilizers) in complete randomize block design with three replication. In both treatments, the first application was conducted when plant high was 10 cm and second application was after 30 days. The harvest carried out before flowering. The results showed that, in comparison of other treatments, the application of nitrogen in form of spry , raised dry mater yield to 5532.8 kgha-1. The LSD test showed that, the spry method was significant (a=%5) to control. In the spry method, nitrogen fertilizer reduced 87.5% to the control. Based on the results, low input Agriculture systems could be introduced for sustainable agriculture.

Melissa officinalis L. is a very easily grown plant that habitats in south and Eastern of Europe, Spain and Asia. The plant of Melissa collected from three fields in Fars, Tehran and Semnan provinces. Essential oils were isolated by hydro-distillation. The yields of Essential oils of Fars sample (Shiraz), Tehran sample (Karaj) and Semnan sample were 0.14%, 0.25% and 0.26% (w/w) respectively. The oils were analyzed by GC (9A-Shimadzu) and GC/MS (Varian 3400). Seventeen constituents at Fars sample oil, seventeen constituents at Tehran sample oil and fourteen constituents at Semnan sample oil were identified respectively. Major constituents of Fars sample were citronellal (25.4%), b-caryophyllene (11.3%), thymol (10.5%), globolol (6.1%), caryophyllene oxide (6.5%) and geraniol (5.7%). Major constituents of Karaj sample oil were citronellal (9.3%), carvacrol (31.8 %), Humulene epoxide (25.4 %) and a-humulene (10.2%). Major constituents of Semnan samples oil were citronellal (43.8%), b-caryophyllene (13.5%), thymol (7.9%), globolol (6.8%), neral (5.3%) and geranial (5.0%). Fourteen constituents were common at all sample oil. Major constituent at all samples oil was citronellal. Four major constituents were common at Fars and Semnan samples oil.
