Eficiência agronômica de estirpes de rizóbio inoculadas em feijão-caupi no Cerrado, Gurupi-TO

Abstract: Resumo -A interação do feijão-caupi com bactérias fixadoras de N atmosférico pode aumentar a produtividade e diminuir os custos de produção. No presente trabalho, avaliou-se, no campo, a eficiência agronômica, através do acúmulo de biomassa da parte aérea, radicular, número e biomassa dos nódulos, eficiência relativa e produtividade de três cultivares de feijão-caupi (BRS Nova Era, BRS Pujante e Vinagre), em experimentos independentes, inoculadas com cinco estirpes de rizóbio, BR 3302 (UFLA 3-84), BR 3301 (INP… Show more

“…These data are consistent with those found by Chagas Junior et al (2010) in studies on the effectiveness of strains of Rhizobium when inoculated into cowpea. They found that BR 3267 has the lowest performance for the number of nodules in relation to the other strains studied.…”

“…Chagas Júnior et al (2010), avaliando o efeito da inoculação com cinco estirpes de rizóbio em cultivares de feijão-caupi, relatam que a estirpe BR3267 apresentou, em condições de campo, baixa eficiência para nodulação em relação à da estirpe BR 3262 e semelhante à das estirpes BR 3301 e BR 3302 para a cultivar Nova Era. No entanto, esses autores comentam que, para a cultivar BRS Pujante, a estirpe BR 3267 mostrou alta eficiência em relação à da estirpe 3262 e semelhante à das demais estirpes testadas.…”

“…According to Frota et al (2008), the cowpea has short cycle, low water requirement and ability to fix atmospheric N through N fixing bacteria. In this context, inoculation with effective rhizobia is a viable alternative to increase the productivity of the crop supplying the N needs by plants, lowering production costs and raising the income of the producer (Chagas et al, 2010). In general, for plant development, there is need for a balance between the water amount and the space occupied by the air in the soil.…”
