“…Application of EM increased the yield of tomato by 11.8-30.7% at the three sites. Similar results were reported by 5 where the yield of peas, sweet potato and onions was enhanced by 31, 23 and 29%, respectively, as a result of EM addition. Since the yields obtained by EM were not significantly higher than those of the control and less than that of 2N, addition of 2N seemed more economical and practical than the use of EM alone.…”

“…EM application was known to improve soil properties, increase the efficiency of organic fertilizers, suppress plant pathogens and pests and enhance crop yield and quality. For example, the use of EM increased the yield of peas, sweet potato and onions by 31, 23 and 29%, respectively 5 . Furthermore; the effect of EM on yield was more profound when it was integrated with the use of organic materials 8 .Similarly, the use of organic fertilizers was found to improve soil properties and crop yield and quality.…”

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.

“…EM influences plant growth by enhancing microbial activity of the indigenous microflora. Application of EM to onion, pea, and sweetcorn cultures increased yields by 29, 31 and 23% respectively (Daly & Stewart 1999). EM application also increased the germination of peanut plants by 2.5% and crop yield by 8.4% in China (Zhao 1992).…”

“…Soil inoculation using EM has been employed over a wide range of agro-ecological conditions (Hussain et al 2002), resulting in enhanced crop productivity, improved soil quality and reduced requirement for chemical fertiliser and pesticides (Hussain et al 1999). EM increased the yield of wheat in China (Hu & Qi 2013), seed cotton in Pakistan (Khaliq et al 2006) and onion in New Zealand (Daly & Stewart 1999), nodulation of pea in Pakistan (Javaid 2006), seedling germination and growth of Albizia saman in Bangladesh (Khan et al 2006), and root collar diameter and height growth of black pine in Turkey (Atik 2013). However, there are contradictory effects of EM on crop yields and soil properties.…”

Improvement in soil physical and chemical qualities in a containerised seedling production system is important to manage the survival of seedlings after transplanting and initial growth for reforestation efforts. The effects of mixed ratio of biochar and effective microorganisms (EM) on the growth of Zelkova serrata seedlings were investigated. Five levels of mixed ratio biochar (0-40% v/v with a growth medium) and two levels of fertilisation, either with or without EM, were applied to seedlings for 5 months. Height, root collar diameter and dry weight of each seedling were measured to compare the effects of the treatments. Main effects of the treatments were evident in all parameters. Growth parameters were much higher in seedlings treated with 1 g L -1 fertilisation, EM treatment and low biochar ratio than those treated with 0.5 g L -1 fertilisation, without EM and with high biochar ratio. Quality index was in the order of as 0% > 10%, 20% > 30%, and 40% mixed ratio biochar. Fertilisation and EM treatment increased quality index by 31 and 13% respectively. No significant interactions were found between treatments. These findings indicate that EM with 1 g L -1 fertilisation at low biochar ratio can be applied for better quality of Z. serrata seedlings in a containerised production system.

“…Many researchers reported better yield of plants cultivated in the ground after treatment with effective microorganisms (Daly and Stewart, 1999;Javaid, 2006;Khaliq et al, 2006;Yan and Xu, 2002). However, other researches indicated that the effect of EM on the growth of plants usually was not evident or it was even negative (Bajwa et al, 1995;Daiss et al, 2008;Javaid et al, 2008).…”
