Faba bean (Vicia faba L.) is a carboxylate-exuding legume that enhances the phosphorus (P) nutrition of subsequently grown cereals. In an earlier study we found variation in soil P acquisition among 50 faba bean genotypes, but little is known about the rhizosphere processes that may contribute to P efficiency and whether these processes impact on the growth of subsequent cereal crops. In this study, we investigated rhizosphere dynamics (P fractions depleted, pH and carboxylate exudation) in three P-inefficient and five P-efficient faba bean genotypes in a glasshouse study on soils differing in P dynamics. The results suggest that P efficiency in the acidic soil was not driven by rhizosphere processes, consistent with earlier findings that root growth parameters contributed to P efficiency in this soil. In contrast, in the alkaline soil the most P-efficient genotypes had the highest malate exudation, which might enhance P solubilisation. For the first time, we showed a faba bean genotype-specific enhancement of growth and P uptake of subsequently grown wheat plants. This genotypic variation could be exploited to further increase the benefit of faba beans in rotation with wheat on P-limited soils.

Abstract We investigated the study of the phytotoxic potential of olive mill wastewaters (OMW) on the germination and growth responses of the faba bean ‘Vicia faba L.’ leguminous plant cultivated under an arid Mediterranean climate. The results showed that the raw OMW blocked the germination of the seeds tested, while OMW treated soil extracts stimulate the seeds' germination rate. The monitoring of the faba bean growth parameters in the different OMW treated soils showed that the optimal growth of the faba bean plants has been recorded for the soil amended with 25 m3 ha−1 of OMW. Although the 50 m3 ha−1 dose is the most suitable for the soil studied, our results showed that the 25 m3 ha−1 dose is the most suitable for the vegetative development, as well as for the productivity of the plant tested ‘Vicia faba L.’.

Faba bean (Vicia faba L.) represents a major source of protein for animal and human nutrition, and provides several benefits such as improved soil quality. The Giza cultivar 87 (Vicia faba L.) was evaluated in three different salinity levels (6.9, 8.7 and 14.8 dSm-1) during two successive cropping seasons (2016-2017 and 2017-2018). The experiment was designed to analyze effect of soil salinity on nitrogen fixation, protein, chemical composition and crop productivity (for both grain and straw). Three phosphorus levels and inoculation with Rhizobium leguminosarum bv. viciae were investigated to improve the growth of Vicia faba L under these conditions. Soil salinity levels reduced the grain number and straw weight of plants. Moreover, yield reductions were associated with increasing soil salinity levels confirming salinity effects on faba bean productivity. Salinity induced a significant decreased in all plant growth parameters, plant chlorophyll and grains proteins, as well as increased Na% of faba bean plants. The plants treated with R. leguminosarum bv. viciae showed significant increase in growth traits such as plant length (%), plant fresh weight (%), protein, N-content and dry weight. On the other hand, the dual treatments with R. leguminosarum bv. viciae plus phosphorus gave a great results compared with inoculation or phosphorus alone. Symbiotic nitrogen fixation inoculation enhanced the growth and yield parameters.

Faba bean (Vicia faba L.) maintain third place with respect to area and production among legume. Its unique ability to excel under all most all type of climatic conditions, it is one of the best performing crops under changing climate scenario. Its soil fertility augmenting potential and their performance was evaluated for two years with 73 accessions collected from Bihar. This study provides glimpses of scope and magnitude of soil fertility improving potential of faba bean (Vicia faba L.)

Pathogenesis-related (PR) proteins are known to play relevant roles in plant defense against biotic and abiotic stresses. In the present study, we characterize the response of transgenic faba bean (Vicia faba L.) plants encoding a PR10a gene from potato (Solanum tuberosum L.) to salinity and drought. The transgene was under the mannopine synthetase (pMAS) promoter. PR10a-overexpressing faba bean plants showed better growth than the wild-type plants after 14 days of drought stress and 30 days of salt stress under hydroponic growth conditions. After removing the stress, the PR10a-plants returned to a normal state, while the wild-type plants could not be restored. Most importantly, there was no phenotypic difference between transgenic and non-transgenic faba bean plants under well-watered conditions. Evaluation of physiological parameters during salt stress showed lower Na+-content in the leaves of the transgenic plants, which would reduce the toxic effect. In addition, PR10a-plants were able to maintain vegetative growth and experienced fewer photosystem changes under both stresses and a lower level of osmotic stress injury under salt stress compared to wild-type plants. Taken together, our findings suggest that the PR10a gene from potato plays an important role in abiotic stress tolerance, probably by activation of stress-related physiological processes.

Auxin not only controls the development processes, but also regulates the stress responses of plants. In this investigation, we explored the potential roles of exogenously applied indole-3-acetic acid (IAA) in conferring salt tolerance in the faba bean (Vicia faba L.). Our results showed that foliar application of IAA (200 ppm) to salt-exposed (60 mM and 150 mM NaCl) plants promoted growth, which was evidenced by enhanced root–stem traits. IAA application ensured better osmotic protection in salt-stressed plants which was supported by reduced proline and enhanced soluble sugar, soluble protein, and total free amino acid contents in the roots, stem, and seeds. IAA application also increased the number of nodules in salt-stressed plants, which may facilitate better nitrogen assimilation. Moreover, IAA mediated improvements in mineral homeostasis (K+, Ca2+, and Mg2+) and the translocation of Na+, while it also inhibited excessive accumulation of Na+ in the roots. Salt-induced oxidative damage resulted in increased accumulation of malondialdehyde, whereas IAA spraying relegated malondialdehyde by improving antioxidant enzymes, including superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase. Together, these results together with a principal component analysis uncovered that foliar spraying of IAA alleviated the antagonistic effects of salt stress via enhancing osmolyte accumulation, ionic homeostasis, and antioxidant activity. Finally, exogenous IAA enhanced the yield of broad beans under high salinity conditions.
