“…Similar results to these found in this study were reported by Campos et al (2000) for inoculation with the commercial product Graminante ® (A. brasilense), which is recommended for corn. This inoculant did not promote any grain yield gains as well; and the authors attributed that to a lack of specificity of the bacteria with corn hybrids (CAMPOS et al, 2000).…”

-This study aimed at evaluating the effect of Azospirillum brasilense, a nitrogen-fixing bacterium, on flooded irrigated rice yield. Evaluations were carried out in a shaded nursery, with seedlings grown on an Alfisol. Were performed two sets of experiments. In the first, were carried out four experiments using the flooded rice cultivars INIA Olimar, Puitá Inta-CL, Br Irga 409 and Irga 424; these trials were set up as completely randomized design in a 5x4 factorial scheme, with four replications. Treatments consisted of five nitrogen rates (0, 40, 80, 120 and 160 kg ha -1 ) and four levels of liquid inoculant Ab-V5 and Ab-V6 -A. brasilense (0, 1, 2 and 4 times the manufacturer's recommendation) without seed treatment. In second set, were performed two experiments using the cultivars Puitá Inta-CL and Br Irga 409, arranged in the same design, but using a 4x2 factorial. In this set, treatments were composed of four levels of Ab-V5 and Ab-V6 -A. brasilense liquid inoculant (0, 1, 2 and 4 times the recommendation of 100 mL ha -1 ), using rice seeds with and without insecticide and fungicide treatment. Shoot dry matter, number of panicles, and rice grain yield per pot were the assessed variables. The results showed that rice seed inoculation with A. brasilense had no effects on rice grain yield of the cultivars INIA Olimar, Puitá Inta-CL, Br Irga 409 and Irga 424.

“…O alto teor de matéria orgânica do solo em que se conduziu o trabalho (50,0 g kg -1 ) pode ter aumentado a disponibilidade de N às plantas, mitigando os benefícios da inoculação das sementes com Azospirillum sp. Campos et al (2000), Godoy et al (2011), Repke et al (2013) e Vogt et al (2014), avaliando inoculantes à base de Azospirillum spp. na cultura do milho em condições de campo, também não encontraram benefícios consistentes da utilização das bactérias diazotróficas sobre a produtividade.…”

Growth and yield of corn hybrids in response to association with Azospirillum brasilense and nitrogen fertilization

et al. 2015

Growth and yield of corn hybrids in response to association withAzospirillum brasilense and nitrogen fertilization 1 There is a growing interest in optimizing the positive effects of the association between Azospirillum bacteria and corn crop in order to reduce the use of nitrogen fertilizers. This study aimed to evaluate the inoculation efficiency of an A. brasilense-based commercial product in association with different rates of nitrogen fertilization in two corn genotypes. The experiment was arranged in a 2 x 2 x 5 factorial randomized block design, with four replications. The treatments consisted of two corn hybrids (30F53 and CD386); with and without inoculation with a commercial product based on A. brasilense and five nitrogen rates (0, 40, 80, 120 and 160 kg ha -1 ). The variables plant height, basal stem diameter, leaf area, shoot dry matter, leaf nitrogen content, length and diameter of the cob, weight of 100 grains and grain yield were evaluated. Inoculation with A. brasilense provided increases of 11 and 12% in leaf area and shoot dry matter, respectively. There were differences in the response of the corn hybrids for most variables and the increase in nitrogen supply provided increments in the growth and yield of corn.
