Resumo: | Biological nitrogen fixation (BNF) is a natural process that occurs between plants and bacteria in an ecological relationship called symbiosis that presents great capacity to minimize the use of nitrogen-rich fertilizers in agricultural systems. Legumes and grasses are important plants in both the socioeconomic and environmental senses in relation to the reduction of impact from agricultural practices on the environment in addition to their ability to fix N together with diazotrophic bacteria, as well as cultivated in intercropping that can affect diversity and efficiency. The aim of the present study was to evaluate the diversity and efficiency of rhizobia obtained from root nodules of leguminous cowpea and pork bean in intercropped and single crops with maize grasses (Zea mays L); sorghum, (Sorghum bicolor (L.) Moench); or millet, (Pennisetum glaucum (L.) R. Br.), as well as whether nodules in consortium alter diversity and efficiency. The experiment was carried out in the field after the process of isolation, authentication and selection of bacteria, using samples of the top layer of a Planossol, following a randomized block design with 5 repetitions and 4 treatments. The diversity indices were calculated and presented averages for: Shannon-Weaver index (H ’) 1.80, Simpson index with 0.78, Margalef index with 2.95 and Pielou Equability Index with 0.95. The evaluation of the average efficiency in the N2 fixation process found that none of the treatments was considered inefficient, the B1T17 treatment was considered efficient with 63.03.18% in relation to the control, whereas the B1T12 treatment was efficient with 100% of efficiency in relation to control and the recommended strain for cowpea showed 83.18% efficiency. At the level of average productivity, the B1T17 treatment produced the highest average with 520 Kg / ha-1 being above the national average, while the B1T12 treatment produced 360Kg / ha-1 and finally the nitrogen treatment (N) with 450 Kg / ha -1. |

Leguminosas e gramíneas são plantas importantes tanto no sentido socioeconômico quanto ambiental, no que tange a redução de impactos das práticas agrícolas sobre o meio, além de sua capacidade de fixação de N juntamente com bactérias diazotróficas assim como cultivadas em consórcio que pode afetar a diversidade e eficiência. O objetivo do presente estudo foi avaliar a diversidade e eficiência de rizóbios obtidos de nódulos radiculares das leguminosas feijão-caupi (Vigna unguiculata (L.) Walp) e feijão-de-porco (Canavalia ensiformes (L)) em cultivos consorciados e solteiros com as gramíneas milho, (Zea mays L); sorgo, (Sorghum bicolor (L.) Moench); ou milheto, (Pennisetum glaucum (L.) R. Br.), bem como se o consórcio altera diversidade e eficiência das populações de rizóbio. O experimento foi conduzido em campo após o processo de isolamento, autenticação e seleção das bactérias, utilizando amostras da camada superficial de um Planossolo. Obedecendo a um delineamento em blocos ao acaso com 5 repetições e 4 tratamentos. Os índices de diversidade foram calculados e apresentaram médias para: Índice de Shannon-Weaver (H’) 1,80, Índice de Simpson com 0,78, Índice de margalef com 2,95 e Índice de Equabilidade de Pielou com 0,95. A avaliação da eficiência média no processo de fixação de N2 constatou que nenhum dos tratamentos foi considerado ineficiente, o tratamento B1T17 foi considerado eficiente com 63,03,18% em relação ao controle, já o tratamento B1T12 mostrou-se eficiente com 100% de eficiência em relação ao controle e a estirpe recomendada para feijão caupi apresentou 83,18% de eficiência. Ao nível de produtividade média o tratamento B1T17 produziu a maior média com 520 Kg/ha-1 estando acima da média nacional, enquanto que o tratamento B1T12 produziu 360Kg/ha-1 e por fim o tratamento nitrogenado (N) com 450 Kg/ha-1.Submitted by (ana.araujo@ufrpe.br) on 2023-08-09T20:17:07Z No. of bitstreams: 1 Philipe Cassio de Almeida.pdf: 2366926 bytes, checksum: 8576a5fa5919187b6fa797a1355de0e3 (MD5)Made available in DSpace on 2023-08-09T20:17:07Z (GMT).
