“…The increment of values in the production variables on inoculated treatments demonstrates the efficiency of these strains to supply the required N and promote vegetal growth. The results obtained in the present work agree with results obtained after inoculating these strains in experiments performed in different soil and climatic conditions by Costa et al (2016), Lira Júnior et al (2017, Marinho et al (2017), Batista et al (2017) and Xavier et al (2017).…”

The objective of this work was to verify the influence of light environments combined with rhizobia inoculation on cowpea growth and productivity. A completely random design was used in a 4x4 factorial scheme, with four light environments, four nitrogen sources and eight replicates in split plot parcels. Light environments were set by means of photo-conversion and thermo-conversion nettings (Aluminet®, red net and black net) and control treatment without shading (full sun). Nitrogen sources were constituted by the strains INPA 03-11B - SEMIA 6462 (Bradyrhizobium elkanni) and UFLA 03-84 - SEMIA 6461 (Bradyrhizobium viridifuturi), and two control treatments: with 70 kg ha-1 of mineral nitrogen and without N. Plant height, indices of chlorophyll a, b and total chlorophill, the number of leaves, number of nodules, dry matter of nodules, dry matter of the aerial portion, dry matter of roots and total dry matter, relative efficiency, gathering of nitrogen in the aerial portion, number, length and matter of pods per plant and dry matter of 100 grains, were evaluated. . There was interaction between light conditions and nitrogen sources for the number of nodules. Individual effect was observed in all other variables. Strain INPA 03-11B was able to promote higher nodulation in cowpea plants in light environments under full sun and Aluminet and the strain UFLA 03-84 only under full sun conditions. However, the efficiency of diazotrophic bacteria to promote vegetative growth, nitrogen gathering and production was not influenced by different light environments. Thus, full sun cultivation is recommended, independently of the nitrogen source used.

“…O maior valor foi adquirido pela inoculação do rizóbio BR85 na lâmina de 100%. Batista et al (2017), não encontraram diferenças significativas em estudo utilizando várias espécies de rizóbios com várias combinações entre eles no período de floração do feijão-caupi. Ayala et al (2014), em trabalho com déficit hídrico com feijão-caupi a partir da floração não encontrou diferenças significativas para essa variável, porém, notou redução de 8,4% nos tratamentos com restrição hídrica.…”

O cultivo do feijão caupi vem se destacando por ser uma cultura adaptável para a região árida e semi-árida do Nordeste brasileiro. Dentre os fatores que reduzem a sua produção, o déficit hídrico e a adubação, tem destaque. Devido a sua capacidade de realizar simbiose com bactérias noduladoras, poderá optimizar a fixação do N2 atmosférico dependendo da combinação e compatibilidade das estirpes envolvidas. O objetivo do trabalho foi avaliar a resposta de plantas de feijão-caupi (cultivar BRS Marataoã) sob déficit hídrico inoculadas e coinoculadas com bactérias fixadoras de nitrogênio. O delineamento experimental utilizado foi o inteiramente casualizado em esquema de parcelas subdivididas com dois fatores (4x5), composto por: T1: BR3264 (A); T2: BR85 (B); T3: BR3264+BR85 (C); T4: controle nitrogenado (CN); T5: controle absoluto (CA), associado com as lâminas de água nas seguintes proporções: 100 %, 80%, 60% e 40% da evapotranspiração da cultura (ETc). As análises foram realizadas aos 45 dias após a emergência (DAE) e compostas de parâmetros filotécnicos (número de folhas, altura da planta, diâmetro do caule, clorofila a, b e total) e bioquímicos (teores de açúcares solúveis totais, açúcares redutores, e prolina). Os resultados obtidos demonstraram que o déficit hídrico ocasionou influência negativa no número de folhas, no diâmetro do caule, na altura das plantas, na clorofila A, na massa seca da parte aérea e na inoculação. A inoculação das cepas de rizóbio é reduzida quando submetida a plantas com estresse hídrico, se sobressaindo cepas nativas. Sendo que a inoculação cruzada favorece a inoculação nessas condições.

“…However, the efficiency of the BNF varies according to the rhizobia strains and the selection of efficient rhizobia become an important step before recommendation to seed inoculation (IRISARRI et al, 2019). Several strains of rhizobia are already Costa et al recommended for different legumes species, such as soybean (MERKEB et al, 2016), and cowpea (BATISTA et al, 2017). So far, lima bean does not have any recommended rhizobia for inoculation and some previous studies have reported potential rhizobia isolates (ANTUNES et al, 2011;COSTA NETO et al, 2017).…”

Seed size influences the promoting activity of rhizobia on plant growth, nodulation and N fixation in lima bean

et al. 2021

This study evaluated the activity of rhizobia isolates inoculated in large (18 mm) and small (11 mm) seeds on lima bean growth, nodulation and N fixation. Selected rhizobia isolates were compared with a reference strain CIAT899 and two controls without inoculation. Large seeds contributed for highest plant growth, nodulation and N fixation than small seeds. The isolates UFPI-59, UFPI-18 and UFPI-38 promoted the highest values of shoot and root dry weight, respectively. The isolates UFPI-32 promoted the highest values of nodule number, while UFPI-59 promoted the highest values of nodule dry weight. The isolates UFPI-38 and UFPI-59 promoted the highest accumulation of N. This study showed that seed size really influences lima bean growth, nodulation and BNF. Considering rhizobia isolates, UFPI-59, UFPI-38, and UFPI-18 contributed for plant growth, promoted better nodulation and effectiveness on biological N fixation.
