“…For example, silicon can reduce sodium and increase potassium uptake in the roots of some legume species under salinity stress, indicating that silicon is able to influence sodium and potassium homoeostasis through effects on this selective transport mechanism. There have also been reports demonstrating the role of silicon in alleviating other abiotic stresses in legumes, such as acidity stress (Owino‐Gerroh, Gascho, & Phatak, 2005), cadmium toxicity (Kabir, Hossain, Khatun, Mandal, & Haider, 2016) and macronutrient deficiency (Miao, Han, & Zhang, 2010).…”

“…Other factors associated with silicon supplementation could also affect root nodulation. Firstly, silicon supplementation can increase soil pH (Haynes & Zhou, 2018; Li et al, 2019) which could, theoretically, promote nodulation under some circumstances since acidity stress can impair root nodulation (Owino‐Gerroh et al, 2005). Nonetheless, the studies outlined in Table 2 use a variety of growing media ranging from hydroponic solutions, where the pH is tightly controlled, to different soil types thus it seems unlikely that pH changes are solely responsible for the beneficial effects of silicon on root nodulation.…”

1. To date, the functional role of plant silicon has mostly been investigated in grasses (Poaceae). This potentially overlooks the importance of silicon in other plant functional groups such as legumes (Fabaceae). Legumes form a symbiotic relationship with nitrogen-fixing bacteria (rhizobia) inside the root nodules for fixing atmospheric nitrogen. A small, but growing number of studies suggest that silicon promotes this symbiotic relationship.2. We consider how legumes may take up and deposit silicon relative to what is known about these processes in grasses. We synthesize information about how silicon affects legume growth and function in the context of environmental stresses and the legume-rhizobia symbiosis.3. The available literature indicates that silicon is broadly beneficial to legumes, alleviating the effects of stresses including metal toxicity, salinity, alkalinity and pathogens. Crucially, there is also evidence that silicon promotes the legume-rhizobia interaction including increased root nodulation, numbers of bacteroids and nitrogen fixation across several legume species. 4. We propose a model for how silicon may benefit the legume-rhizobia interaction. We hypothesize that silicification in the tissues may reduce the high metabolic cost of carbon-based compounds in cell wall construction, optimize solute transport and gas exchange in root nodules and/or promote protection against environmental stresses. We therefore propose a hypothetical framework to better understanding the impacts of silicon on legume-rhizobia relationships.5. We also suggest potential research priorities that would help us to better understand the functional role of silicon in nitrogen-fixing legumes. These research priorities focus on characterizing how silicon affects the chemical dialogues between the host plant and its rhizobial partner, how silicon is deposited in legume roots and how resources are exchanged by the two. Given the growing importance of legumes at a global scale, silicon could play a vital role in improving legume health and productivity with manifold environmental benefits.

“…It is well established that a synergy of benefits can occur and that the host plant can gain more from tripartite interactions than from single inoculations with either symbiont (Afkhami & Stinchcombe, 2016;Antunes, de Varennes, Zhang, & Goss, 2006;Bournaud et al, 2017;Meng et al, 2015;Yasmeen, Hameed, Tariq, & Ali, 2012). The N-fixing capability of rhizobia is often limited by the P availability, and AM fungi can stimulate root nodulation, nitrogenase activity, and BNF through their positive effect on plant P nutrition (Ding et al, 2012;Owino-Gerroh, Gascho, & Phatak, 2005;Püschel et al, 2017;Vesterager, Nielsen, & Hogh-Jensen, 2006). Plants can simultaneously benefit from N that is provided by both root symbionts, and nodulated legumes colonized by AM fungi with access to an external NH 4 + source became less reliant on BNF (Mortimer, Perez-Fernandez, & Valentine, 2012).…”

Legumes form tripartite interactions with arbuscular mycorrhizal fungi and rhizobia, and both root symbionts exchange nutrients against carbon from their host. The carbon costs of these interactions are substantial, but our current understanding of how the host controls its carbon allocation to individual root symbionts is limited. We examined nutrient uptake and carbon allocation in tripartite interactions of Medicago truncatula under different nutrient supply conditions, and when the fungal partner had access to nitrogen, and followed the gene expression of several plant transporters of the Sucrose Uptake Transporter (SUT) and Sugars Will Eventually be Exported Transporter (SWEET) family. Tripartite interactions led to synergistic growth responses and stimulated the phosphate and nitrogen uptake of the plant. Plant nutrient demand but also fungal access to nutrients played an important role for the carbon transport to different root symbionts, and the plant allocated more carbon to rhizobia under nitrogen demand, but more carbon to the fungal partner when nitrogen was available. These changes in carbon allocation were consistent with changes in the SUT and SWEET expression. Our study provides important insights into how the host plant controls its carbon allocation under different nutrient supply conditions and changes its carbon allocation to different root symbionts to maximize its symbiotic benefits.

“…Ces différents résultats, parfois contradictoires pourraient suggérer qu'en ce qui concerne la fertilisation de C. cajan, chaque variété constitue un cas particulier. En effet, selon les analyses des résultats de plusieurs auteurs (Tayo et Togun, 1984;Adu-Gyamfi et al, 1997a;Adu-Gyamfi et al, 1997b;Katayama et al, 1999;Owino-Gerroh et al, 2005;Bertolin et al, 2008;Kimaro et al, 2009 ;Fageria et al, 2013 ;Fageria et Baligar, 2014), la réponse de C. cajan à la fertilisation dépend de la classe du sol, de son pH, du statut de fertilité (riche en azote, en phosphore et en potassium ou non, fumure ou non), du type de fertilisant (ternaire, binaire, fumure organique, etc.) du système de culture (intercalaire ou pure), du calendrier de fertilisation, du mode d'épandage et de gestion de la fertilisation et de la variété.…”

The aim of the present work was to evaluate the effect of phosphorus and potassium fertilization on the production and the quality of pigeon pea seeds produced on a ferrasol type sol. A completely randomized block design was used, in a 2x3x3 factorial set with three replications. A density of 20 000 plants ha -1 was used. The treatments were 0, 40, 80, units for phosphorus (P2O5) and potassium (KCl). Treatment which received P80K80 fertilization had greater productivity (650 kg) but a low germination rate (30 %). The optimal dose (523 kg and 90 % germination rate) was obtained with P40K80, followed by P40K40 dose (516 kg and 82 % germination rate). Phosphorus and potassium had mutually acted and influenced positively the production and the quality of the seeds of C. cajan.
