“…In a previous study, Franzini et al (2013) demonstrated that Aporé and Ouro Negro yielded similar GDW values in an experiment with low (2.2 mg N kg -1 soil) and high N content in the soil (200 mg N kg -1 soil). The values of %Ndfa found in this study were comparable to the values reported by Hardarson et al (1993), who observed 70% Ndfa in common beans grown in a field under favorable environmental conditions. Similarly, Rondon et al (2007) showed values from 50 to 72%.…”

“…Nevertheless, some studies indicate that indigenous rhizobia strains are not efficient in common bean BNF, and these strains could hinder the introduction of more efficient strains (Vieira, 1998a), which is usually attributed to the lack of competitiveness against indigenous rhizobia, environmental conditions and plant genetic factors (Piha & Munns, 1987;Hardarson et al, 1993).…”

The common bean has been considered to have low biological nitrogen fixation capacity; however, this process can be made more effective with molybdenum (Mo) supplementation. The objective of this study was to evaluate the influence of Mo rates on the growth and biological nitrogen fixation by two Brazilian common bean cultivars using the 15N isotope dilution technique. The experiment was performed in 2014 in a completely randomized design arranged in a 5 x 3 factorial scheme, corresponding to 5 rates of Mo (control, 40, 80, 120 and 240 g ha-1), the common bean cultivars Aporé, Ouro Negro and NORH-54 (a non-nodulating common bean cultivar), and three replicates. The application of Mo and the inoculation with rhizobia strains contributed to improving nitrogen fixation and grain weight. The cultivar Ouro Negro showed a higher number and weight of nodules and a higher amount of nitrogen derived from the atmosphere than the cultivar Aporé. The biological nitrogen fixation of Aporé was more dependent on the application of Mo. These results indicated that inoculation with Rhizobium strains and Mo supply effectively contributed to biological nitrogen fixation and improving grain production.

“…Houve redução da massa de nódulos, entre os estádios de floração e início de enchimento de vagens, de 73 para 54 mg por planta, respectivamente (Figura 1), o que denota um processo de senescência de nódulos nos estádios reprodutivos, que está associado à menor aquisição de N simbiótico pelo feijoeiro (Piha & Munns, 1987). Todavia, as quantidades de N oriundos da simbiose podem representar um aporte expressivo de N para o feijoeiro (Hardarson et al, 1993), que pode assumir ainda maior relevância em sistemas orgânicos de produção, em que a menor disponibilidade de nutrientes oriunda da mineralização dos fertilizantes orgânicos pode reduzir o rendimento dos cultivos em algumas situações (Sacco et al, 2015). Graham et al (2003) relacionaram alguns caracteres com potencial para a seleção de genótipos de feijoeiro, com maior contribuição do N oriundo da simbiose, tais como massa de nódulos, duração do período de fixação de N, retardamento da senescência nodular, alta acumulação de massa de matéria e de N da parte aérea.…”

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. Index terms: Phaseolus vulgaris, organic fertilization, special beans, genotype, nodulation. IntroduçãoOs sistemas orgânicos de produção podem contribuir com a produção sustentável de alimentos, por meio da redução da degradação do solo, do aumento da resistência de cultivos a estresses hídricos e a ataques de pragas e doenças, aumento da segurança alimentar e mitigação das mudanças climáticas (Azadi et al., 2011). A adoção de sistemas orgânicos de produção enfrenta...

“…The nitrogen fertilizers use is indicated in some situations to achieve good yields, even though they may affect negativity the BNF efficiency. Mean values of 35% and maximum of 70% of N derived from the atmosphere were observed at the plant biomass considering six field experiments in tropical countries and Austria [88]. Some progress is occurring with the best selection of strains, adapted to the conditions of each site [89][90][91][92].…”

Organic Fertilizers - From Basic Concepts to Applied Outcomes

Tropical areas have prevalence of soils with low fertility, which makes the management of soil fertility a necessary practice to maintain a farming system economically and environmentally sustainable. The purpose of this chapter is to demonstrate the importance of green manure and the use of crop residues as management for soil fertility. We highlight the potential of these practices to increase/sustain productivity by providing nutrients. First, we made a short review on the main factors influencing the decomposition and mineralization processes. Subsequently, we discuss green manure techniques, presenting the main green manures, criteria for choosing, managements, potential for nutrient accumulation, and advantages and disadvantages of this practice. Finally, we use some examples to demonstrate the potential nutrient supply of crop residues from the main crops grown in the tropics. The difficulties and limitations involved are also discussed.
