In an era that has been exposed by growing environmental concerns and the urgent need to review the common methods of producing agricultural products and achieving sustainable agriculture, the use of "green technologies" has emerged as the final solution. The identification of factors driving the development of emerging green technologies to achieve sustainable agriculture was carried out. The type of descriptive-survey research and its statistical population were technology experts in the public and private sectors and users of emerging green technologies, 314 of them based on the table of Karjesi and Morgan by random sampling with proportional assignment. were investigated. The tool of data collection was a questionnaire, the validity of which was obtained by referring to experts in agricultural technologies, and the calculation of Cronbach's alpha coefficient (0.931) confirmed its reliability.Data were classified by SPSS version 21 software and exploratory factor analysis technique. The results showed that seven factors include the realization of sustainable agriculture, increasing efficiency and productivity in production, improving the form and quality of agricultural products, optimal use of production factors and cost reduction, penetration of green technologies in the agricultural production system, development of technology culture and innovation. In the society and increasing public awareness of emerging green technologies, more than 75% of the total variance of the factors promoting the development of emerging green technologies to achieve sustainable agriculture are explained.

To study of combined effect of vermicompost and nitrogen fertilizers, nitroxin on yield and yield components of potato a factorial based on randomized complete block design (RCBD) with three replications was conducted in Damavand city in 2015. The first factor was three levels of vermicompost including no application (control), application 5 and 10 ton.ha-1 and the second factor was four levels of nitrogen fertilizers and Nitroxin including no application(control),application 100% of the recommended consumption nitrogen fertilizers(150kg.ha-1urea),application nitrogen bio fertilizer (5kg.ha-1Nitroxin)and application 75% of the recommended consumption nitrogen fertilizers(100kg.ha-1urea) and nitrogen bio fertilizer (5kg.ha-1Nitroxin). Analysis of variance showed that vermicompost and integration of nitrogenous fertilizer and Nitroxin in most traits were significant. Results of mean comparison showed that the highest tuber yield of five tons per hectare use of vermicompost (22/52 kg.ha-1) and taking seventy-five percent of the recommended amount of nitrogenous fertilizer with biological Nitroxin (23/8 kg.ha-1). Finally the consumption of 5 tons per hectare use of vermicompost and application 75% of the recommended consumption nitrogen fertilizers (100kg.ha-1urea) and nitrogen bio fertilizer (5kg.ha-1Nitroxin) the results were the best

Intercropping and plant growth-promoting rhizobacteria improve sustainability of agro-ecosystems. To evaluate the effect of Azotobacter (Azotobacter chroococcum) inoculation on productivity of a peanut /maize intercropping system, a two-year study was design as a randomized complete block in a factorial arrangement with three replicates at Astaneh-ye Ashrafiyeh, Guilan province. Factors were Azotobacter inoculation [control (non-inoculated) and inoculated with Azotobacter chroococcum) and intercropping pattern (Sole cropping of peanut and maize, additive intercropping pattern at three levels (100% peanut + 100% maize, 100% peanut + 50% maize, and 50% peanut + 100% maize), and replacement intercropping pattern at three levels (50% peanut + 50% maize, 67% peanut +33% maize, and 33% peanut + 67% maize). Results showed that gain yields of maize and peanut were significantly affected by Azotobacter inoculation and intercropping pattern. Inoculation with Azotobacter chroococcum significantly increased grain yields of peanut and maize by 10% and 16%, respectively. Maximum and minimum of land equivalent ratio (LER) were observed at 100% peanut + 50% maize and 50% peanut + 50% maize, respectively and inoculated intercropped plots with Azotobacter chroococcum had 12-16% grater LER that non-inoculated ones. Regards to impossibility of mechanical weed control by machines in additive intercropping patterns, to obtain the highest productivity in maize/peanut intercropping system, intercropping pattern of 100% peanut + 50% maize along with Azotobacter application will be suitable in fields with low weed density. Otherwise, based on LER and grain yield of peanut, the intercropping pattern of 67% peanut + 33% maize along with Azotobacter application will be suitable.

Using of substances such as ethanol and methanol can be considered as a way to improve plants yield helping carbon dioxide fixation increment. The effect of methanol and ethanol spraying on growth and essential oils of peppermint has been studied in field conditions based on randomized complete block design with 10 treatments including spraying with 10, 20, 30 and 40% methanol and ethanol, distilled water and no spraying.There was an enhancingeffect of ethanol and methanol spraying on most of studied traits.Methanol had positive effect on leaf number, longest lateral branch length and leaf width. Also, ethanol increased essential oils content, shoot fresh and dry weight and lateral shoot number. In general, the best treatments effecting on plant traits were ethanol 20 and 30% and methanol 10 and 30%. The highest essential oils content was observed at 10% of methanol 10 – 30% of ethanol. To foliar improvement, 30% of methanol was the most suitable treatment. Therefore,with economic and availability considerations, methanol would be recommendable formore essential oils contentachievement. Also, for the best peppermint business performance, 30% methanol could be applicable.
