“…In both Acacia species, the MWR and PTWR water treatments affected on nodulation, they significantly increasing the number and dry weight of nodules. Similar results have been reported in other studies (Stamford and Silva 2000;Al-Fredan, 2006;Carvalho et al, 2012). Abd-Alla et al (2012, 1999 indicated that moderate application rates of sewage sludge increased the nodulation and nitrogen fixation in some legume crops.…”

“…Several studies have also showed increasing in the growth parameters of trees and crops after irrigation with treated wastewater (Kiziloglu et al, 2008;Bedbabis et al, 2010;Akponikpèa, 2011;Pandey andSrivastava, 2012, andSelahvarzi andHosseini, 2012). Moreover, Carvalho et al (2012) found that the height and nodulation of Leucaena leucocephala and Mimosa caesalpiniaefolia significantly increased when treated with sewage effluent and inoculated with Rhizobium.…”

The scarcity of irrigation water is one of the vital factors limiting crop production in arid countries. The critical shortage of water necessitates the development of new water sources, and the use of wastewater is considered one of the best solutions for solving this water scarcity. An experiment was conducted to investigate the effect of primary treated wastewater irrigation on growth parameters, nodulation, macro and micronutrients for Acacia ampliceps (Maslin.) and Acacia origena (Hunde.) seedlings grown in the Dirab Valley, South of Riyadh City. The study included four irrigation treatments: municipal water plus Rhizobium inoculum (MWR), primary treated wastewater plus Rhizobium inoculum (PTWR), municipal water only (MW), and primary treated wastewater only (PTW). The results revealed that the PTWR and PTW treatments were effective for increasing the growth parameters and nodulation of the Acacia seedlings. The combination of primary treated wastewater and inoculation with Rhizobium significantly improved the growth parameters, nodulation, and nutrient content of the seedlings. Overall, the combination of treated wastewater and Rhizobium can be used as a potential source of nutrients and water for tree legume plantations in the arid areas of Saudi Arabia.

“…Improved performance of crop (yield and yield attributes) in sewageirrigated fields was due to increased chlorophyll content and photosynthesis rate compared to bore well-irrigated crop (Table 4). De Carvalho et al (2012) also recorded improved legume performance with sewage irrigation. Among the sources of irrigation, sewage irrigation and alternate irrigation have added to nitrogen contribution and thus increased the N content and thus increasing protein and grain yield.…”

Background Evaluation of urban sewage for its feasibility and potentiality as sources of irrigation water and plant nutrient is need of the hour. In this context, a field experiment was laid out in split-split plot design with three replications. Main plots constituted two types of lands (fields irrigated with sewage and bore well water since 1992). Subplots were allotted with three sources of irrigation which consisted of sewage water alone, bore well water alone (good water) and conjunction of sewage and bore well water. And sub-subplot constituted of four fertilizer levels (no fertilizer, 50 % recommended rate of fertilizer (RRF), 75 % RRF and 100 % RRF. Results Crop growth in terms of photosynthesis, net assimilation rate and dry matter production significantly increased in sewage-irrigated land compared to bore wellirrigated land. Similarly, significantly higher wheat grain yield (4370 kg ha-1), protein (12.88 %) and dry gluten (9.22 %) were obtained in field irrigated with sewage water compared to bore well-irrigated land. Sources of irrigation also differed significantly producing higher grain yield (4,100 kg ha-1), protein (12.81 %), dry gluten (8.97 %) in sewage irrigation compared to bore well water irrigation. Enhanced activity of dehydrogenase and phosphatase enzymes and organic carbon in sewage-irrigated field contributed more to available nutrient pool of soil. Pooled results of 2 years revealed that wheat roots accumulated significantly higher amount of Cr, Ni, Pb and Cd in sewage-irrigated land compared to bore well-irrigated land. The same trend was noticed in stem with respect to Cr and Ni. In general, concentration of heavy metals was higher in root followed by stem and lower in grain. The Pb concentration in plant parts (root, stem and grain) was not influenced by land type and sources of irrigation. None of the treatments did show accumulation of these heavy metals in wheat plant parts more than normal range found in food plants. The values of these metals were below the recommended maximum tolerable levels proposed by the Joint FAO/WHO Expert Committee on Food Additives, Summary and conclusions. In: 53rd Meeting, Rome, (1999). Conclusion Increased wheat grain yield in sewage-irrigated land compared to bore well-irrigated land was attributed to increased soil fertility that was a result of continuous sewage irrigation. Long-term irrigation of farm lands with wastewater leads to contamination of soil and plant system with heavy metals in the study area. Wastewater-irrigated soil showed significant (p \ 0.05, p \ 0.01) accumulation of heavy metals compared to the freshwater-irrigated soil indicating concern of their increased absorption in wheat plant. The accumulation of heavy metals in wheat plant was in the order of roots [stems [ grains. However, all these heavy metals in plant system were lower than the recommended threshold level.

“…This latter helps replenish N in the soil through N-rich litter-fall, along with root and nodule turnover which are necessary for plant growth and protection (Scheublin and Vander, 2006). Studies demonstrated the beneficial effects of inoculating legumes with rhizobia (de Carvalho et al, 2012;Ravikumar, 2012). Ceccon et al (2011) found that the inoculation with Sinorhizobium americanum could improve the Acacia farnesiana growth and the re-establishment of important plantsoil interactions in degraded areas.…”

Effects of dual inoculation with arbuscular mycorrhizal fungi and rhizobia on Acacia senegal (L.) Willd. seedling growth and soil enzyme activities in senegal

Acacia senegal (L.) Willd. is a multipurpose legume that is economically and ecologically important in Sahelian areas, especially in Senegal. It has long been used for arabic gum production. However, drought and overexploitation lead to decreased soil fertility and tree productivity. An experiment was conducted to examine the response of A. senegal seedlings to inoculation with mixed arbuscular mycorrhizal fungi (Glomus fasciculatum, Rhizophagus irregularis and Glomus verriculosum) and rhizobial strains (ORS 3574, ORS 3593, ORS 3607 and ORS 3628) in glasshouse conditions. After 6 months of culture under non-sterilized field soil from Dahra (northern part of Senegal), plant height, arbuscular mycorrhizal root colonization rate and soil acid phosphatase activity were significantly enhanced by the combined inoculation of arbuscular mycorrhizal fungi (AMF) and rhizobia. However, plant biomass, soil spore density and hyphal length were significantly improved by the single inoculation with mycorrhizal or rhizobial strains. The number of nodules was higher for rhizobial inoculated plants. No significant increase in shoot nutrient contents was observed after inoculation. The microbial inoculation enhances the soil acid phosphatase activity whereas no positive effect was noticed on soil total microbial activity. These results indicate that the single inoculation with AMF or rhizobia improves A. senegal seedling growth under this non-sterilized field soil better than the dual inoculation. It is suggested that, for the success of a dual inoculation, a careful selection of effective combinations of microsymbionts is necessary to enhance plant growth and soil bio-functioning and for restoration of soil fertility in a given environment.
