“…Em outros trabalhos, contudo, a fixação biológica consegue suprir apenas parte do N necessário (KUKAMI et al, 2016), sendo a adubação nitrogenada indispensável para a obtenção de bons resultados (Morais et al, 2016). Além disso, há casos onde a simples inoculação permite a obtenção de bons rendimentos ou de ganhos em crescimento das culturas (GARCÍA-OLIVERAS, 2012;BRUM et al, 2016;MARTINEZ et al, 2016). A não obtenção de qualquer ganho pela inoculação também é relatada na literatura (REPKE et al, 2013).…”

Resumo -O objetivo do estudo foi avaliar a eficiência agronômica da inoculação de sementes de trigo e de milho com Azospirillum brasilense, em associação à adubação nitrogenada. Sete tratamentos foram avaliados, associando a inoculação com aplicação de nitrogênio (N), sob delineamento de blocos ao acaso, com 4 repetições, totalizando 28 unidades experimentais com área individual de 27,2 m 2 . Na cultura do trigo foi avaliado o número de perfilhos por planta, número de espigas por metro quadrado, número de grãos por espiga, rendimento de massa seca e grãos, massa de mil grãos e peso hectolitro. No milho foi analisado o diâmetro de colmo, área foliar, índice de área foliar, altura de plantas, rendimento de grãos, massa de mil grãos, diâmetro e comprimento de espigas. Os resultados demonstraram que a inoculação não representou ganhos nos diferentes atributos avaliados. A associação da inoculação com adubação com N mineral aumentou a produtividade e a produção de matéria seca. A redução pela metade da adubação de N em cobertura, quando associada à inoculação, não afetou a resposta das culturas nos diferentes atributos avaliados. Conclui-se que a inoculação apresenta boa resposta nas culturas de trigo e milho quando associada à adubação nitrogenada. Palavras-chave: inoculação, produtividade, Triticum aestivum, Zea Mays.Abstract -The aim of the study was to evaluate the agronomic efficiency of wheat seed inoculation and corn with Azospirillum brasilense, in combination with nitrogen fertilization. Seven treatments were evaluated, involving inoculation with nitrogen (N), under design of a randomized block design with four replications, totaling 28 experimental units with individual area of 27,2 m². In wheat crop was rated the number of tillers per plant, number of ears per square meter, number of grains per spike, dry matter yield and grain, thousand grain weight and hectoliter weight. Maize was analyzed the stem diameter, leaf area, leaf area index, plant height, grain yield, thousand grain weight, diameter and length of spikes. The results showed that inoculation did not represent gains in different attributes evaluated. The association inoculation with fertilization with mineral N increased productivity and production of dry matter. The reduction by half of the fertilizer nitrogen in when associated with inoculation did not affect the response of crops in different attributes evaluated. It is concluded that the inoculation presents good response in wheat and corn crops when associated with nitrogen fertilization.

Benefits in grain productivity, with low economic cost, ease of application, without causing toxic damage to the environment and with high potential for crop response, are target points in research involving the cultivation of corn. In this context, the present study aimed to evaluate the effect of inoculation of Azospirillum brasilense on the vegetative structures of the corn crop, envisioning an increase in the development of the plant. The experimental design used was completely randomized, with six treatments and four replications, totaling 24 experiments. Seeds were inoculated with A. brasilense in different doses of the commercial product (0 - 1000 mL), where the plant height (AP), ear insertion height (AIE), stem diameter (DC), total number of leaves (NTF) and number of leaves below the first ear (NFAE), were evaluated. The inoculation of corn seeds based on A. brasilense strain Ab-V5 promoted influence on some biometric variables, with an increase in the total number of leaves (NTF), plant height (AP) and height of ear insertion (AIE) for the evaluated hybrid, resulting in increments in its vegetative development. The dosage of 549 mL per hectare was considered as favorable to result in greater amounts of total leaves (NTF) in the plant, according to the adjustment of the proposed model. The results emphasized that inoculation with this strain is a valid technique and is increasingly used by farmers, and its study is a contributing factor for improvements in agronomic parameters.

The objective was to evaluate the inoculation, co-inoculation with bacteria B. japonicum and A. brasilense in combination with application of N doses on the agronomic characteristics of soybean. The design used was randomized blocks in a 4x4 factorial scheme, with four types of inoculation (absence of inoculation, inoculation of B. japonicum bacteria, inoculation with A. brasilense and co-inoculation with B. japonicum and A. brasilense) and four doses of N (0 % = 0; 2 % = 4.5; 4 % = 9 and 8 % = 18 kg ha-1), with four replications. The increasing doses and above 2% of N promoted a reduction in the number of nodules formed by B. japonicum in the roots. The number of nodules and root dry mass was higher at the dose of 8% N, with an average of 317 nodules per plant and 23.42 g plant-1 referring to the treatment with the inoculant A. brasilense. The nodulation efficiency obtained a value of 354 g kg-1 when the dose of 2% of N was used. if co-inoculation. The practice of nitrogen fertilization resulted in an increase in the number of nodules only for the bacteria A. brasilense and significant gains of N in the plant only at the dose of 8% of N.
