“…This lack of significant correlation between shoot biomass at flowering and grain yield in common bean has also been reported in previous studies (Stone & Pereira, 1994;Araújo et al, 2000). Pires et al (2005) also observed that the yield potential of five soybean cultivars estimated at flowering did not correlate with grain yield at maturity.…”

“…Pereira et al (1989) also verified that shoot mass of field-grown bean lines increased throughout the growth cycle, and that larger differences in shoot mass among lines were found at later growth stages. In 1998, the amount of biomass, N and P in shoots increased continuously after flowering, confirming that bean is able to maintain growth and nutrient acquisition during the reproductive development (Araújo et al, 2000). However, in 1999 shoot growth ceased between R7 and R8, and the amounts of N and P in shoots of indeterminate cultivars decreased (Tables 2 and 3), partially due to rust incidence that provoked some leaf senescence.…”

“…Although grain yield can be related to leaf area duration and shoot mass within the same common bean cultivar (Laing et al, 1984;Stone & Pereira, 1994), bean shoot biomass of different cultivars did not correlate with grain yield at any P level applied to the soil Araújo et al, 2000), indicating that the relationship between vegetative vigor and yield did not apply to the different genotypes. Notwithstanding, the identification of a specific period of crop development, regarded as critical for crop establishment, could indicate appropriate agronomic practices for maximizing crop yield.…”

SUMMARYShoot biomass is considered a relevant component for crop yield, but relationships between biological productivity and grain yield in legume crops are usually difficult to establish. Two field experiments were carried out to investigate the relationships between grain yield, biomass production and N and P accumulation at reproductive stages of common bean (Phaseolus vulgaris) cultivars. Nine and 18 cultivars were grown on 16 m 2 plots in 1998 and 1999, respectively, with four replications. Crop biomass was sampled at four growth stages (flowering R6, pod setting R7, beginning of pod filling R8, and mid-pod filling R8.5), grain yield was measured at maturity, and N and P concentrations were determined in plant tissues. In both years, bean cultivars differed in grain yield, in root mass at R6 and R7 stages, and in shoot mass at R6 and R8.5, whereas at R7 and R8 differences in shoot mass were significant in 1998 only. In both years, grain yield did not correlate with shoot mass at R6 and R7 and with root mass at R6. Grain yield correlated with shoot mass at R8 in 1999 but not in 1998, with shoot mass at R8.5 and with root mass at R7 in both years. Path coefficient analysis indicated that shoot mass at R8.5 had a direct effect on grain yield in both years, that root mass at R7 had a direct effect on grain yield in 1998, and that in 1999 the amounts of N and P in shoots at R8.5 had indirect effects on grain yield via shoot mass at R8.5. A combined analysis of both experiments revealed that biomass accumulation, N and P in shoots at R6 and R7 as well as root mass at R6 were similar in both years. In 1998 however bean accumulated more root mass at R7 and more biomass and N and P in shoots at R8 and R8.5, resulting in a 57 % higher grain yield in 1998. This indicates that grain yield of different common bean cultivars is not intrinsically associated with vegetative vigor at flowering and that (1) Solo, 32:1977Solo, 32: -1986Solo, 32: , 2008 mechanisms during pod filling can strongly influence the final crop yield. The establishment of a profuse root system during pod setting, associated with the continuous N and P acquisition during early pod filling, seems to be relevant for higher grain yields of common bean.Index terms: common bean, genotype, ontogeny, Phaseolus vulgaris, plant growth, root. RESUMO: RELAÇÕES ENTRE O RENDIMENTO DE GRÃOS E A ACUMULAÇÃO DE BIOMASSA, NITROGÊNIO E FÓSFORO EM CULTIVARES DE FEIJOEIROA biomassa de parte aérea é considerada um componente relevante para o rendimento dos cultivos, mas é usualmente difícil estabelecer relações entre produção biológica e rendimento de grãos em leguminosas. Foram realizados dois experimentos de campo com o objetivo de investigar as relações entre o rendimento de grãos, a produção de biomassa e a acumulação de N e P em estádios reprodutivos de cultivares de feijoeiro (Phaseolus vulgaris).

Resumo -O objetivo deste trabalho foi avaliar o crescimento e a produção de cultivares de feijoeiro-comum (Phaseolus vulgaris), de diferentes tipos comerciais de grão, em sistema orgânico de produção. Dois experimentos foram realizados em campo com 16 cultivares em delineamento experimental de blocos ao acaso, com 16 tratamentos e 4 repetições. As sementes receberam inoculação com rizóbios, tendo-se utilizado esterco bovino ao plantio e torta de mamona em cobertura. As cultivares de feijão diferiram quanto à nodulação, ao acúmulo de matéria seca e de N na parte aérea, à produção de grãos e aos componentes de produção, com interações significativas entre cultivares e anos quanto à produção. A produtividade média de grãos das cultivares foi de 2.035 e 1.704 kg ha -1 em 2011 e 2012, respectivamente, em que se destacam BRS Pontal, BRS Campeiro, BRS Radiante, Aporé e Constanza, com produtividade acima de 1.900 kg ha -1 na média dos dois anos. A produtividade foi maior nas cultivares com sementes grandes, em 2011, e maior nas de sementes pequenas em 2012. As cultivares BRS Radiante e Constanza, de grãos de tipos especiais com perspectivas de nichos de mercado com maior valor de comercialização, apresentam bom desempenho no sistema orgânico de produção.Termos para indexação: Phaseolus vulgaris, adubação orgânica, feijões especiais, genótipo, nodulação. Performance of common bean cultivars in organic production systemAbstract -The objective of this work was to evaluate the growth and grain yield of common bean (Phaseolus vulgaris) cultivars of different market grain types, in organic production system. Two field experiments were carried out with 16 cultivars, in a randomized complete block design with 16 treatments and four replicates. Seed were inoculated with rizobia, cattle manure was applied at sowing and castor bean press cake was applied at side dress. Bean cultivars differed for nodulation, accumulation of dry matter and N in the shoots, grain yield and yield components, with significant interactions between cultivars and years for grain yield. Average grain yield of cultivars was 2,035 and 1,704 kg ha -1 in 2011 and 2012, respectively, for which BRS Pontal, BRS Campeiro, BRS Radiante, Aporé, and Constanza outstood with more than 1,900 kg ha -1 average across two years. Grain yield was higher in large-seeded cultivars, in 2011; and in small-seeded ones, in 2012. The BRS Radiante and Constanza cultivars, with grains of special types with potential for market niches with improved commercial prices, show good performance in the organic production system.

“…Bean production is constrained by low phosphorus; the need for bean varieties are capable of acquiring phosphorus from limiting soil environments is of obvious importance. The ability of common bean to acquire phosphorus from phosphorus-limiting environments has been reported to vary among genotypes and this ability is heritable [8,9]. Nevertheless, increased root growth and modified architecture [10], altering the root growth angle [11] and production of adventitious roots [12], have all been reported to be the root traits that are necessary for adaptation of bean to phosphorus limiting environment.…”

Common bean production in Tanzania is constrained by soil phosphorus which is mainly due to inherently low phosphorus content, soil erosion, and fixation by oxides in acidic soils. A study was conducted to evaluate bean genotypes in a screen house pot experiment for their ability to thrive and produce on low phosphorus soil. Assessment of shoot biomass, root biomass, shoot P concentration, P uptake, and yield components was done using three phosphorus levels and seven bean genotypes. Phosphorus levels, namely, control (P0), medium P (40 mg P/kg), and high P (160 mg P/kg), were the main plot factor, while the genotypes were the subplot in split plot structure, arranged in a completely randomized design. Shoot and root biomass as well as P uptake increased significantly with increase in phosphorus levels. There was varying response of genotypes in performance in terms of shoot biomass P uptake, and yield in a treatment without P addition. Genotypes MILENIO, BAT477, and A785 were outstanding in terms of root and shoot biomass, P uptake and grain yield under low P treatment. Therefore, those genotypes can be recommended for use in low-phosphorus environment as well as breeding materials.
