O tamanho da semente é um importante indicador físico da qualidade fisiológica das sementes, pois pode afetar a taxa de germinação e o crescimento inicial das plântulas. Neste contexto, o presente estudo teve como objetivo avaliar os efeitos do tamanho das sementes e da inoculação de Bradyrhizobium japonicum e Azospirillum brasilense de forma isolada ou combinada na emergência das plântulas, nodulação das raízes e no crescimento inicial das plantas de amendoim (Arachis hypogaea L., cv. IAC Tatu ST). As plantas foram cultivadas em vasos plásticos de 8,0 L preenchidos com um solo arenoso do Cerrado e mantidas sob condições de casa-de-vegetação. O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial 3 × 4 com quatro repetições. Os tratamentos foram constituídos por três tamanho de sementes (pequena, média e grande) e por quatro tratamentos de inoculação: i) controle (sem inoculação); ii) inoculação das sementes com Bradyrhizobium japonicum; iii) inoculação das sementes com Azospirillum brasilense; e, iv) coinoculação das sementes com B. japonicum e A. brasilense. Os resultados reportaram que a utilização de sementes grandes melhorou a nodulação das raízes, o crescimento das plantas, o acúmulo e a partição de matéria seca das plantas. Portanto, a implantação da cultura do amendoim deve ser realizada com a utilização de sementes de maior tamanho (grandes), por proporcionar sustentabilidade para o sistema de produção de amendoim, melhorando a fixação biológica de nitrogênio e o crescimento das plantas cultivadas em solos arenosos do Cerrado Sul-mato-grossense. A coinoculação das sementes com B. japonicum e A. brasilense melhorou a nodulação das raízes e a altura das plantas, no entanto, não teve efeito no crescimento, na partição de matéria seca e nos índices morfofisiológicos das plantas de amendoim, quando cultivadas em solos arenosos do Cerrado sob condições controladas.

ABSTRACT This study aimed to verify the effect of co-inoculation, association between Azospirillum brasilense and Bradyrhizobium japonicum bacteria, on soybean plants subjected to water deficit at two sowing dates. Two field experiments were conducted at the Universidade Federal de Tocantins, campus of Palmas, Brazil, in 2016. The experimental design was randomized blocks in a split-split-plot arrangement with four repetitions, where the plots consisted of two irrigation depths (100 and 25% of crop evapotranspiration - ETc), the subplots was composed of two methods of inoculant application (inoculation with Bradyrhizobium japonicum and co-inoculation with Azospirillum brasilense + Bradyrhizobium japonicum) and the sub-subplots comprised two soybean cultivars (TMG 132 and ANTA 82). The cultivars responded differently to the sowing dates. Co-inoculation did not influence grain yield under full irrigation conditions (100% ETc), in neither cultivar evaluated. However, under the water deficit condition (25% ETc), the grain yield of the cultivar TMG 132 increased 77.20%, indicating that there are different responses of interaction between Azospirillum brasilense, plant genotype and sowing dates.

A field experiment was conducted for three years under irrigated conditions for productivity enhancement of soybean through integrated nutrient and other agronomic interventions. Application of N, P, K and FYM significantly enhanced the yield of soybean over control. Maximum yield was observed in the treatment where FYM was applied with NPK and resulted in an increase of 15.1 per cent over NPK alone. Application of additional 30 kg N ha-1 at pre-flowering or at pod initiation did not significantly enhance the yield over the basal dose of NP applied at sowing. Application of 4 tonnes wheat straw mulch + 30 kg N +60 kg P2O5 and 30 kg N + 60 kg P2O5 ha-1 showed similar effect on seed yield of soybean. No statistical difference in soybean yield was obtained in the conventional flat and bed sowing treatments. Pre-emergence application of pendimethaline @ 1.5 l ha -1 along with one hand weeding at 40 days after sowing (DAS) and two hand weeding at 20 and 40 DAS were equally effective for weed control and in influencing the soybean yield. The application of N, P, K, FYM, in different treatments, treatment with Bradyrhizobium japonicum and sowing on beds all significantly improved the N, P and K uptake by soybean over control. Application of FYM to soybean resulted in maximum enhancement of nutrient uptake by soybean. After three years a significant improvement in soil OC, available N, P and K was observed in all treatments over control.

In lysimetric experiment with soybean, the effect of complex inoculants based on Bradyrhizobium japonicum and Azospirillum brasilense on the vertical migration of biogenic elements have been studied. When growing without application of mineral fertilizers, bacterization helped to reduce losses of nitrogen, phosphorus, potassium, calcium, magnesium compounds, as well as moisture and water-soluble humus. Also reduction in loss of biogenic elements compounds under the action of inoculants on the background of N30 was found, but bacterization not affect the loss of moisture and humus. It was shown that complex inoculants affect biometric parameters of soybean plants and enhances the productivity of this culture.

The paper presents the research results of pre-sowing seeds bacterization with nitrogen fixing bacteria Bradyrhizobium japonicum and Azospirillum brasilense influence on the loss of moisture, water soluble humus and nutrients. It was shown that seeds bacterization reduces the leaching intensity of nitrates, phosphorus, potassium, calcium and magnesium. Moreover, the least losses of nutrients were observed in a variants with joint application of both studied nitrogen fixing microorganisms. It was noted that seeds bacterization with B. japonicum and A. brasilense had promoted increase of chlorophyll content in the leaves of soybean plants. The highest yield was observed in the variant with the joint use of rhizobia and azospirillum.
