“…In this regard, while in Biari et al (2008), Costa et al (2015) and Morais et al (2016) found an increase in seed weigh of maize after inoculation; on the other hand, no significant interaction between inoculation and seed weigh was reported by Novakowiski et al (2011). Also, Dobbelaere et al (1999) reported that inoculations with A. brasilense did not impact GNC in maize.…”

The continuous development of soybean cultivars aiming at higher yields can result in a demand of N supply higher than the standard inoculation with Bradyrhizobium species. In this context, Azospirillum species, a nitrogen-fixing microorganism found in the rhizosphere of various plant species, may be studied as a way of providing soybean crop with the part of the N it needs. Employing a completely randomized design with four replicates, this study aimed to evaluate the agronomic performance of two different methods of standard inoculation of Bradyrhizobium spp. associated with the co-inoculation with Azospirillum spp. The tested treatments consisted of the absence of N fertilizer and inoculant, full N recommendation, two single inoculations with Bradyrhizobium spp. (in-furrow and seed-applied) combined with an in-furrow application of Azospirillum spp. At R 2 growth stage, the nodule number, nodule dry weight, shoot dry biomass and shoot N content were the variables evaluated, whereas at R 8 the grain yield, thousand seed weight and grain N content were assessed. The results demonstrated that the co-inoculation of Bradyrhizobium spp. with Azospirillum brasilense is beneficial to soybean yield, mainly using the in-furrow method of application for Bradyrhizobium spp., associated to the infurrow co-inoculation with Azospirillum spp.

“…In this regard, while in Biari et al (2008), Braccini et al (2012), Costa et al (2015) and Morais et al (2016) found an increase in seed weigh of maize after plant inoculation combined to N fertilizer rates, on the other hand, in Novakowiski et al (2011) there was no significant interaction between N levels and inoculation for TSW. However, while the later authors used the bacteria strain Sp245, Hungria et al (2010) pointed out that only the strains AbV4, AbV5, AbV6 and AbV7 are the most effective for maize.…”

A B S T R A C TThis study aimed to evaluate the agronomic performance of different doses of Azospirillum brasilense in peat formulation on maize crop grown under limited N fertilization, using a completely randomized design with four replicates. The treatments tested consisted of absence of N fertilizer, the full N recommendation and a combination of the half of recommended N associated with the inoculation of three doses of A. brasilense in peat formulation (100, 150 or 200 g per 25 kg of seeds). The following variables were evaluated: insertion height of the first ear height, number of kernel per row, number of row per ear, shoot dry biomass, root dry biomass, chlorophyll content, thousand seed weight, grain N content, shoot N content and grain yield. Half the dose of N fertilizer combined with 150 g per 25 kg of seeds of A. brasilense in peat formulation provided significantly superior results in agronomic performance of maize, particularly regarding grain yield, thousand seed weight and dry biomass of both shoot and root.

“…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).…”

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.
