ResumenEl cultivo de vainita está bastante difundido en la costa sur peruana que tiene características desérticas. Se trabajó a nivel de laboratorio, para producir el inoculante y aplicarlo en campo, mediante un diseño en bloques completamente aleatorizado. Los tratamientos fueron: inoculante 2. suelo, control negativo agua destilada, testigo fertilizado y testigo biológico. Se cuantificó el número de nódulos por planta y el porcentaje de nódulos efectivos por planta. En cada cosecha se determinó el rendimiento por hectárea, rendimiento por planta, longitud de vaina, peso de vaina y número de vainas por planta. Se determinó la influencia de la inoculación con diferentes concentraciones de Rhizobium etli sobre el rendimiento de este cultivo. El tratamiento inoculado con una concentración de 2.5 x 10 9 cel g -1 suelo generó el mayor número de nódulos totales con un promedio de 47.67 y con una efectividad de 84.02%. Este tratamiento produjo una mayor influencia en el rendimiento por hectárea, rendimiento por planta y número de vainas por planta, al mismo tiempo que no tuvo diferencia significativa al ser comparado con el testigo fertilizado. Palabras clave: rizobio, cepa, vaina, inoculante, nódulos y nitrógeno. AbstractThe green bean crop is fairly widespread in the Peruvian southern coast which has desert features. At the laboratory level, we worked to produce the inoculant and to apply it in the field through a completely randomized blocks design. The treatments were the following: inoculant 2. soil generated the largest number of total nodules with an average of 47.67 and an effectiveness of 84.02%. This treatment produced a higher influence on the yield per hectare and per plant and the number of pods per plant, but it did not have a significant difference when it was compared with the fertilized control. Key words: rhizobia, strain, pod, inoculant, nodules and nitrogen. Introducción.Aproximadamente el 85% de la fijación de nitrógeno en la tierra tiene un origen biológico. En la fijación de nitrógeno, éste se reduce a amoniaco que es convertido en forma orgánica, esta actividad es característica de algunos procariotas. Bacterias como los rizobios pueden hacer simbiosis con las raíces de plantas leguminosas, formar nódulos radicales y realizar la fijación biológica de nitrógeno (Madigan et al., 2000).La fijación biológica de nitrógeno es un proceso natural e importante dentro de la agricultura mundial. Los cálculos globales estimados en cuanto a esta fijación, específicamente relacionadas a la simbiosis entre los rizobios y los cultivos de leguminosas son alrededor de 20-22 millones de toneladas de nitrógeno por año (Herridge et al., 2008). La mayor parte del nitrógeno fijado por las leguminosas es retirado durante la cosecha, siendo las semillas las que presentan un alto valor proteico. Sin embargo, es conocido también que el cultivo de leguminosas mejora la productividad en cultivos posteriores, debido a una mejor disponibilidad de nitrógeno en los suelos (Peoples et al., 2009).La aplicación de fertilizantes q...

“…The existence of variability among common bean lines for response to SNF has already been observed in wild germplasm, accessions from germplasm banks (Ferreira et al, 2010;Knupp et al, 2013;Farid and Navabi, 2015), and among breeding lines (Kamfwa et al, 2015;Pereira et al, 2015;Farid et al, 2016Farid et al, , 2017. Variability is also found among common bean genotypes regarding N absorption efficiency (Fageria et al, 2013;.…”

“…Evaluating and selecting lines that were developed in a growing system with mineral N fertilization, but have superior performance in a system with Rhizobium inoculation, may permit immediate use of these lines as new cultivars in low N fields. In addition, since these lines already have various favorable agronomic phenotypes accumulated over years of selection, they can be used in crosses as a source of alleles of agronomic traits (Pereira et al, 2015).…”

“…Few studies have evaluated agronomic traits in common bean production systems dependent on SNF, with the exception of a few studies on seed yield and 100-seed weight (Pelegrin et al, 2009;Fageria et al, 2014;Pereira et al, 2015;Farid et al, 2016;Heilig et al, 2017). Results have been variable, due to differences in genetic variability for N fixing ability, as well as in the environmental variability that affects the common bean host and the N -fixing bacteria (Hungria and Vargas, 2000;Devi et al, 2013).…”

Nitrogen (N) is the most important soil nutrient for common beans; the main sources are mineral N fertilizers and symbiotic N fixation (SNF). The common bean (Phaseolus vulgaris) is a N fixing species, but breeding programs have neglected this fact. We investigates black seeded elite lines grown with mineral N fertilization or using inoculation with rhizobia to select lines with broad adaptability, high yield stability, and high agronomic performance. Fifteen black seeded common bean elite lines and cultivars, all of them selected under mineral N fertilization, were evaluated in major bean crop regions in the Brazilian states of Goiás, Paraná and Distrito Federal in different growing seasons and years, totaling 13 environments (combination of location/growing season/year). Two side-by-side experiments were set up in each environment, one exclusively with mineral N fertilization (total of 80 kg ha -1 of N) and another with Rhizobium inoculation only. The agronomic traits evaluated were seed yield, 100-seed weight, sieve yield, reaction to anthracnose and angular leaf spot. The nodulation traits evaluated were number of nodules and nodule dry matter, specific weight of nodules and relative nodulation index. The N ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 19 (2): gmr18491 P.A.S. Dias et al. 2source significantly affected seed yield, 100-seed weight and reaction to anthracnose. All lines produced a higher yield and had higher 100seed weight under N mineral fertilization; but they were more resistant to disease when inoculated with rhizobia. The interaction between lines and N sources was significant for seed yield, sieve yield, and reaction to anthracnose. However, it did not affect selection of the best lines regardless of N source. The cultivars BRS FP403 and BRS Esteio are recommended for planting with either of the two N sources because they were the highest yielding and exhibited high adaptability and stability under both N supply systems. Selection of superior lines does not appear to depend on the source of N used during crop development. The lines BRS Campeiro and CNFP 15177 gave the highest nodulation index, indicating that these lines should be used in crosses with high yielding lines to produce lines with high seed yield and high nodulation, reducing possible yield losses in SNF systems compared to those that useonly mineral N fertilizer.

“…Responsive cultivars and efficient rhizobia (native rhizobia or those introduced through inoculation) have led to satisfactory yields that are equivalent, or even superior, to those obtained from mineral nitrogen fertilization. Yet, there are materials that are more dependent on nitrogen fertilizers for their development than others (Grange, Hungria, Graham, & Martínez-Romero, 2007;Arf et al, 2011;Fageria, Ferreira, Melo, & Knupp, 2014;Pereira et al, 2015). Moreover, other factors, such as those inherent to the crop growing environment, soil fertility, edaphic factors, and climatic conditions, should not be ignored, due to their possible effects on the BNF symbiotic process.…”

The BRSMG Uai common bean cultivar (Phaseolus vulgaris L.) unites traits required by producers, such as high yield and upright stands, the latter of which is considerably improved in relation to previously released cultivars such as BRSMG Madrepérola and Pérola. However, the potential of the cultivar to form symbiotic relationships with rhizobia to fix N2 has not yet been assessed. Here, field experiments were conducted to assess the efficiency of biological nitrogen fixation (BNF) in the cultivar, and to compare this to the efficiencies of other genetic materials widely grown throughout Brazil (BRSMG Madrepérola and Pérola). Experiments were conducted on two Oxisols in Minas Gerais State, Brazil (one during the dry season in the south, and the other during the winter season in the Alto-Paranaíba region), under a no-tillage system over maize stover. A randomized block experimental design was implemented in a 3 × 3 factorial arrangement with four replicates. Individual and combined Analysis of Variance were performed and the data were normalized. Homogeneity of the residual mean squares was observed. Significant effects of factors were identified by Scott-Knott tests and F tests. The BRSMG Uai cultivar responded to inoculation with the rhizobial strain CIAT 899, with yields similar to those achieved upon fertilization with 80 kg ha-1 of N-urea and to the yields of the BRSMG Madrepérola and Pérola cultivars inoculated with the same rhizobial strain. In terms of commercial use, this cultivar may be successful under either of the management practices adopted for N supply, and from the perspective of plant breeding, it has potential for inclusion in breeding programs directed toward improving BNF.
