“…Globally, low availabile P in many weathered tropical soils is a major constraint to common bean production (Lynch et al 2009 ), as the P requirement of legumes is greater when compared to cereals (Silva et al 2014 ). In Africa, the low P availability is exacerbated by soil degradation and inadequate fertilisation especially in smallholder agriculture, even though P supply to common bean has been shown to enhance nodulation, symbiotic efficiency and the uptake of mineral nutrients (Stamford et al 2007 ; Mandri et al 2012 ; Neila et al 2014 ; Tajini and Drevon 2014 ).…”

A field experiment was conducted to assess plant growth, symbiotic performance and grain yield of common bean in response to rhizobial incoculation and phosphorus application at Galalicha in Southern Ethiopia during the 2012 and 2013 cropping seasons under rain-fed conditions. The treatments consisted of 2 released common bean varieties (Hawassa Dume and Ibbado), 3 levels of Rhizobium inoculation (uninoculated, inoculated with strain HB-429 or GT-9) and 4 levels of phosphorus application (0, 10, 20 and 30 kg P ha−1) using a split-split plot design with four replications. Here, phosphorus levels, Rhizobium inoculation and common bean varieties were assigned as main, sub- and sub-sub treatments, respectively. The results revealed marked varietal differences in plant growth, grain yield and symbiotic performance. Of the two common bean varieties studied, Hawassa Dume generally showed superior performance in most measured parameters in 2013. Rhizobium inoculation significantly (p ≤ 0.05) increased plant growth, symbiotic performance and grain yield. Applying Rhizobium strain HB-429 to bean crop respectively increased plant growth, %Ndfa, amount of N-fixed and grain yield by 19, 17, 54 and 48% over uninoculated control. Similarly, the application of 20 kg P ha−1 to bean plants respectively resulted in 36, 20, 96 and 143% increase in plant growth, %Ndfa, N-fixed and grain yield when compared to the control. These results clearly indicate that plant growth, symbiotic performance and grain yield of common bean can be significantly increased by Rhizobium inoculation and phosphorus fertilization in Ethiopia. Rhizobium inoculants are a cheaper source of nitrogen than chemical fertilizers and when combined with moderate phosphorus application can markedly increase grain yield for resource-poor farmers.

Lima bean stands out in the agricultural sector as a source of income for small and medium farmers, being an important protein source for the population. However, there few studies related to the adequate management of fertilization that subsidize the maximization of crop production. In this context, the objective of this research was to evaluate the effect of macronutrient doses on the yield components and nutritional status of lima bean. The treatments were chosed based on the statistical arrangement of the Baconian method. Six nutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) were applied in three different doses along with two additional treatments, one with reference doses and the other with no addition of nutrients, totaling 20 treatments that were arranged in a completely randomized design with four replications. The pod length, pod number per plant, pod weight, number of grains per pod, number of grains per plant, grain weight per plant and macronutrient leaf contents were evaluated. The addition of macronutrients leads to increases in yield components and nutritional status of lima bean s when cultivated in Entisol Quartzipsamment. The doses of macronutrients that promote higher productive yield and adequately supply the nutritional needs of lima beans are: 25 mg N dm-3; 157 mg P2O5 dm-3; 90 mg K2O dm-3; 1.27 cmolc Ca dm-3; 0.50 cmolc Mg dm-3 and 30 mg S dm-3.

“…The common bean genotypes selected, IAC-Imperador (P-e cient) and Dor-364 (P-ine cient), were previously characterized in hydroponics studies as e cient and ine cient in P uptake [25]. We selected two sources of phosphate based on their solubility, triple superphosphate (TSP), which is a readily available source, and rock phosphate Bayovar (RPB), which relies mainly on plant exudates and microorganisms' activity to become available [20,26].…”

Background Phosphorus (P) availability is the main nutritional factor that limits crops yields in tropical soils due to edaphic processes that lead to P immobilization after mineral fertilization. Considering the potential of the rhizosphere microbiome to transform insoluble P into forms readily available for plant uptake, in this study is proposed that plants with contrasting P uptake efficiency, growing under depleted amounts of P are able to shape distinct bacterial communities in the rhizosphere enriching taxa specialized in P mobilization. Methods We selected two common bean genotypes contrasting in P efficiency uptake and grew them in a soil with a gradient of two different sources of P, triple superphosphate (TSP) or rock phosphate Bayovar (RPB). The rhizosphere bacterial community was assessed by 16S rRNA amplicon sequencing. Data analyses focused in describing the structure of the bacterial communities, identification of OTUs differentially enriched in different treatments, functional metagenomic prediction and cooccurrence network. Results P sources and levels resulted in different rhizosphere bacterial community structure. A high number of differentially enriched OTUs were observed under P depleted conditions in the P-inefficient genotype, mainly belonging to Actinobacteria phylum. The P-inefficient genotype did not show significant differences in the rhizosphere bacterial community assembly growing in different P sources. Predicted metagenome profiles showed the enrichment of bacterial functions involved in P mobilization, in the rhizosphere of the P inefficient genotype cultivated in P depleted conditions. The network analysis revealed that in the rhizosphere of the P-inefficient genotype under P depleted conditions the bacterial community has a higher number of nodes and edges, higher average degree and clustering coeficient when compared to the treatment with optimal P level. Conclusion Our data showed that the uptake of exogenous input resulted in the assembly of a P-competent microbiome in the P-inefficient genotype compared to the efficient one, supporting the hypothesis that the selective pressure for the P uptake engages P-inefficient genotypes in symbiotic relationships with the soil microbiome. These results will pave the way for future experimentation aiming at explore the contribution of this P-competent microbiome to plant growth and development in a range of soil type.
