“…Coffee has a high genetic variability and several studies indicate variation between different genotypes in relation to absorption and translocation of nutrients (Amaral et al, 2011), including zinc and P (Reis and Martinez, 2002), potassium, calcium, magnesium, and sulfur (Tomaz et al, 2003, 2008), boron, zinc, copper, and manganese (Tomaz et al, 2011), but few have explored P use efficiency. In research conducted by Martins et al (2015), the authors indicated high genotypic variability for Coffea canephora genotypes cultivated in environments with low Pi availability in the soil and classified seven of the 13 cultivars studied as tolerant to low soil Pi availability.…”

Background and Aims: Phosphate (Pi) is one of the most limiting nutrients for agricultural production in Brazilian soils due to low soil Pi concentrations and rapid fixation of fertilizer Pi by adsorption to oxidic minerals and/or precipitation by iron and aluminum ions. The objectives of this study were to quantify phosphorus (P) uptake and use efficiency in cultivars of the species Coffea arabica L. and Coffea canephora L., and group them in terms of efficiency and response to Pi availability.Methods: Plants of 21 cultivars of C. arabica and four cultivars of C. canephora were grown under contrasting soil Pi availabilities. Biomass accumulation, tissue P concentration and accumulation and efficiency indices for P use were measured.Key Results: Coffee plant growth was significantly reduced under low Pi availability, and P concentration was higher in cultivars of C. canephora. The young leaves accumulated more P than any other tissue. The cultivars of C. canephora had a higher root/shoot ratio and were significantly more efficient in P uptake, while the cultivars of C. arabica were more efficient in P utilization. Agronomic P use efficiency varied among coffee cultivars and E16 Shoa, E22 Sidamo, Iêmen and Acaiá cultivars were classified as the most efficient and responsive to Pi supply. A positive correlation between P uptake efficiency and root to shoot ratio was observed across all cultivars at low Pi supply. These data identify Coffea genotypes better adapted to low soil Pi availabilities, and the traits that contribute to improved P uptake and use efficiency. These data could be used to select current genotypes with improved P uptake or utilization efficiencies for use on soils with low Pi availability and also provide potential breeding material and targets for breeding new cultivars better adapted to the low Pi status of Brazilian soils. This could ultimately reduce the use of Pi fertilizers in tropical soils, and contribute to more sustainable coffee production.

Studies on nutritional efficiency of phosphorus in conilon coffee plants are important tools to unravel the high limitation that natural low levels of this nutrient in soil impose to these species cultivars. Therefore, this study aimed at evaluating the nutritional efficiency and the response to phosphorus of conilon coffee clones. Plants were managed during 150 days in pots containing 10 dm³ of soil, in greenhouse. A factorial scheme 13 x 2 was used, with three replications, being the factors: 13 clones constituting the clonal cultivar "Vitória Incaper 8142" and two levels of phosphate fertilization (0% and 150% of the P2O5 usualy recommended), in a completely randomized design (CRD). The results indicate a differentiated response of dry matter production and of phosphorus content on each level of phosphate fertilization for the conilon coffee clones and that CV-04, CV-05 and CV-08 clones are nutritionally efficient and responsive to the phosphate fertilization.

“…Variability for the nutritional efficiency among genotypes of other species of coffee have been reported in several other researches (Amaral et al, 2011;Martins et al, 2013a, b;Colodetti et al, 2015;Tomaz et al, 2011), including differences for the efficiency in absorb Means of roots N content from unfolding the interaction for genotypes C. arabica (a) and N supply (b), N content of above-ground organs for genotypes (c) and N supply (d), and total N content for genotypes (e) and N supply (f) (means followed by the same letter do not differ by the Tukey test at 5% of probability). and utilize N (Colodetti et al, 2014;Machado et al, 2016).…”

The different responses of improved genotypes to alterations of the availability of nutrients indicate that it is possible to modulate the nutritional efficiency by exploring the interaction between the intrinsic response of a genotype and the level of nutrient supply. The objective of this research was to assess the response of genotypes of Coffea arabica L., from different parental lineages, to contrasting environments for N supply, using parameters of growth and nutritional efficiency indexes to explore a possible increase in the nutritional efficiency. The experiment followed a 3×3 factorial scheme, in a completely randomized design, with 3 improved genotypes (Acauã, Katipó and Topázio) and 3 environments with different levels of N availability in the soil (50, 100 and 200% of the recommended supply). The growth and nutritional efficiency of C. arabica is influenced by the effects of the intrinsic differences among genotypes and can be modulated by changes in the environment, based on the response to different supplies of N in the soil. Genotypes from different parental linages are able to present highly contrasting responses to the fertilization with N, indicating a high variability to be explored. Among the studied genotypes, Topázio presents higher accumulation of biomass and high nutritional efficiency for absorbing, translocating and using N in environments with low fertility; while Acauã presents higher efficiency in environments with higher N supply.
