Abstract:Effective microorganisms impact on photosynthetic activity of Arabidopsis plant grown under salinity stress conditions. Salinity is one of the main abiotic stressors which affects plant growth through various physiological processes such as photosynthesis. The aim of this work is to study the impact of salinity stress on Arabidopsis plants by evaluating plant growth rate and photosynthetic activity, while investigating the influence of effective microorganisms (EMs) with the objective to determine if EMs could alleviate the induced stress affiliated with salinity. Results showed that salinity negatively affects photosynthesis efficiency in Arabidopsis plants based on the data obtained from the measured chlorophyll fluorescence parameters. Additionally, application of EMs enhanced plant tolerance to counteract the induced stress. Effective microorganisms concentration of 10 mL/L suggested to bring about the best results. This work advocates, that quantum efficiency of photosystem II (PSII) is a reliable indicator for tolerance in Arabidopsis plants to salinity stress, the impact of which may be softened by the EMs.

“…Hence, the EM was expected to enhance the rate of decomposition and in turn improved the efficiency of organic materials as a fertilizer 6,9 . Although it was not yet well known how EM improved the growth of plants, it was thought that this was through EM production of growth regulators, hormones and antioxidants 16,17 . In the present study, the use of EM enhanced the efficiency of manure in boosting up the yield of tomato by 18, 12 and 7% at Medani, Shendi and Hudieba, respectively.…”

Objective: This study was conducted to investigate the effect of effective microorganisms (EM), farm yard manure and nitrogen on yield and quality of tomato. Methodology: A factorial experiment was carried out at the Research Farm of Gezira (Medani), Shendi and Hudieba in 2009/10. The factors studied were N (0 and 2N as urea), farm yard manure (0 and 10 t/ha) and EM (-or +). The treatments were arranged in RCBD with four replicates. The data collected involved tomato marketable yield and quality in term of fruit firmness and total soluble solids. Results: The results revealed that 2N application significantly increased the yield at Medani and Hudieb but not at Shendi. EM improved the yield of the control and manure by 12-31 and 7-18%, respectively, but these increments were not significant. The highest yield of tomato was recorded at Medani and Hudieba in manure integrated with 2N. However, the yield obtained by the use of manure alone was not significantly different from that of manure with 2N but significantly the highest among the other combinations at Shendi. Each of N and manure significantly improved the firmness of tomato at Medani. Hence, manure applied separately or integrated with 2N could be used for the organic production of tomato and yield maximization, respectively, at Medani and Hudieba. Separate use of manure was suggested for both yield maximization and organic tomato production at Shendi. Conclusion: It could be concluded that the integrated use of manure and nitrogen fertilizer significantly resulted in the highest tomato yield when the total soil N is low as in Medani and Hudieba. Application of manure alone showed comparable yield to that of combined manure and 2N but significantly higher than that of 2N when the total soil N is high as in Shendi.

Geranium plants were cultivated in a growth chamber with different light quality and microorganism inoculation conditions. The long-term effect of irradiance quality (LED and fluorescent) as well as two types of microorganism treatments on photosynthetic activity parameters was examined. The maximum reached values of net photosynthesis rate (P N ), stomatal conductance (g s ), transpiration rate (E) and intercellular CO 2 concentration (C i ) were afterwards measured in plants cultivated under six colours of light -white, white-blue, blue, red, red-blue and green -emitted by two types of lamp: LED and fluorescent. Two types of microorganism treatments were used: BAF 1 created in the Department of General and Environmental Microbiology and the commonly used Effective Microorganisms (EM) biopreparation. A highest level of P N were found in plants after cultivation under white-blue light (both -fluorescent and LED) and treated by BAF 1 . The positive effect of EM was only noted in the case of plants cultivated under blue-red fluorescent light. Considering plants without microbial inoculation the highest levels were recorded in plants under red and blue light. The comparison of the effect of light quality revealed that in all colours a higher or similar level of net photosynthetic rate was noted in plants under LEDs. Mostly the higher photosynthetic activity was connected with higher stomatal opening as well as with higher transpiration rate, which is especially true for plants cultivated under red and blue LED light.
