“…These result could be attributed to Azotobacter, Azospirillum, Bacillus megatherium and Bacillus circulans by increasing leaf nitrogen, phosphorus and potassium content which indicated that the biofertilizers might have created certain microbial environment in the root rhizosphere zone for better uptake of NPK. Such conclusion was confirmed by Srivastava et al, (2002). As regard to micronutrients showed in Table 7 that the uptake of Fe and Mn were improved with the application of T 6 .…”

A field experiment was carried out during the years 2013, 2014 and 2015 on Eureka lemon at El-Nubaria region, El-Beheira governorate, to study the effect of farmyard manure and biofertilizers with NPK dose on soil fertility, growth, yield, fruit quality and leaf nutrient content of Eureka lemon trees. Eleven treatments were arranged in a randomized complete block design with three replicates. Results revealed significant differences amongst various growth attributes, fruit yield, fruit quality, leaf mineral content and soil nutrients availability due to farmyard manure and biofertilizers application. Also, farmyard manure and biofertilizers could compensate for the 50% reduction of chemical fertilizers, and increasing yield compared to chemical fertilizers with significant differences. Therefore, treatment of 50% NPK + 55 kg farmyard manure + biofertilizers is recommended for growers. This treatment gave the best growth, yield and fruit quality of Eureka lemon trees. Moreover, this treatment improved the nutritional status of the trees, through the beneficial effects of organic and biofertilizers which enhanced the availability of most nutrients in the soil.

“…Second, phosphatase produced by AM fungi has been shown to play an important role in the transforming of fixed or insoluble P into soluble types, which makes the P available for plants (Neumann and George, 2004; Abd‐Alla et al, 2000). It was found that in mycorrhizal plants, the enhancement of growth and nutrient uptake (mainly P) affect the host plant water relations (Srivastava et al, 2002; Subramanian et al, 2006). In addition, it has been suggested that mycorrhizal fungi affect the host plant’s growth under drought stress through improvement of P acquisition because the availability of P in soils was found to be reduced in drying soils (Subramanian et al, 2006; Tobar et al, 1994).…”

“…A higher root hydraulic conductivity value and a reduction in the plant transpiration rate were shown in AM plants under water‐deficit stress (Aroca et al, 2008; Auge, 2001, 2004). Furthermore, it has been reported that water deficit affects plant growth rate and nutrient uptake depending on the intensity and duration of the stress, and both water and nutrient uptake in water‐deficit‐stressed mycorrhizal plants were higher than in nonmycorrhizal plants (Srivastava et al, 2002). For example, mycorrhizal colonization was found to improve not only the plant yield (biomass and fruit yield) and water use efficiency but also the concentrations of nutrients were increased (macro nutrients N, P, K, Ca, and Mg and micronutrients Zn, Fe, and Mn concentrations in the leaves) in watermelon [ Citrullus lanatus (Thunb.)…”

Arbuscular mycorrhizal fungi are considered to have the potential to increase the tolerance of host plants to water-defi cit stress. Th is is due to their apparent role in water and nutrient uptake and transfer to their host plants. To evaluate the eff ects of mycorrhizal fungi species and water-defi cit stress on mung bean [Vigna radiata (L.) R. Wilczek var. radiata] plants, a 2-yr split-plot experiment based on a randomized complete block design with three replications was conducted in the fi eld in 2009 and 2010. Treatments were the application of various irrigation levels (irrigation aft er 50, 100, 150, and 200 mm of evaporation from a Class A pan as the main plot) and inoculation with two mycorrhizal fungal species (Glomus mosseae, G. intraradices, and uninoculated plants as subplots). Our results from 2 yr of experiment indicates that the highest (1833.51 and 479.15 kg ha -1 ) and lowest (1139.56 and 333.99 kg ha -1 ) seed and protein yield were obtained from plants irrigated aft er 50 and 200 mm of evaporation, respectively; however, the maximum (0.60 kg m -3 ) and minimum (0.32 kg m -3 ) ecosystem water use effi ciency was observed in plants irrigated aft er 200 and 50 mm of evaporation, respectively. Seed yield, biological yield, leaf P, leaf N, protein percentage, protein yield, harvest index of protein, and ecosystem water use effi ciency were improved in mycorrhizal plants compared with the non-mycorrhizal plants. Our results suggest that both G. mosseae and G. intraradices signifi cantly improved the yield (seed and protein) and reduced the water-defi cit stress in mung bean plants in the fi eld.

“…Use of vermicompost in the sustainable agriculture caused significant increases in the population of beneficial microorganism such as mycorrhizal fungi and phosphate dissolving bacteria and fun gi in the soil. Production of nutritious elements such as nitrogen, transferable phosphor, magnesium, dissolved potassium required for the plants and causes improvement in the growth and function of the agricultural plants (Martinez et al, 2000;Kumar & Singh, 2001;Srivastava et al, 2002). Information's regarding the effect of fertilizers on the functioning of maize crop are in scarcity therefore present study has been conducted to find out the effect of chemical nitrogen fertilizer and vermicompost on the function and component of maize seed traits.…”

(0), 5 and 10 tons in hectare. Results of the study showed a significant correlation between the quantitative traits of maize seed and various levels of chemical Nitrogen fertilizer and vermicompost. Highest functioning of maize seed was obtained from the treatment containing 100 percent Nitrogen and 10 tons/hectare of vermicompost while the lowe st amount was obtained from the treatment containing 50 percent Nitrogen without vermicompost application. Furthermore, application of vermicompost and chemical Nitrogen fertilizer affects the biological f unction and increase in the yield of seed in rows and weight of each 1000 seeds, also has positive and meaningful effect on the index of maize seed's harvesting. The results of the study revealed that the application of Nitrogen fertilizer at the levels of 50 and 75 percents of area soil test and vermicompost at the level of 5 tons in a hectare in this area are appropriate to obtain the maximum yield and proper functioning.
