Comparison of bio-fertilizers and manure on properties of lemon balm herb farm

In order to study the effects of organic fertilizers and biological growth characteristics, and quantitative and qualitative performance lemon balm herbs factorial experiment in a randomized complete block design with 12 treatments and 3 replications has done in the 1393 crop year in Mahmud Abad city in the Mazandaran province .Thefirst factor in the 3 levels of use of sheep manure at 5 and 10 tonnes per hectare and the use, or control, of the second factor at four levels of bacteria Azotobacter and B. respectively from the strains (chrococcum and pobilis), combining bacteria and consumption respectively.The results showed that the use of biological fertilizers and manure to Root length, root Weight, root volume, root dry weight, essential oil, Oil yield and Total dry weight than the control treatment and the most effective combination of sheep manure and bacteria to increase yield were studied. Sheep manure and bacteria interactions revealed that the highest elevation in the treatment of bacteria with an average consumption of 10 tons and the combination of the average 43.66 cm and the lowest average 24 cm in the treatment of non-use of sheep manure and bacteria, respectively.Using a combination of bio-fertilizer and animal treatment, leads to an increase of 55 percent compared to other control, that is total dry weight of the plant.
