Agricultural practices such as the use of cover crops inoculated with microorganisms aim to transform productive systems into sustainable ecosystems, since it reduces negative impacts on the environment and production costs and at the same time, increases the productivity of the main crops by improving soil attributes. This study aimed to determine the effect of the application of beneficial rhizobacteria in cover crops grown in the off-season, the accumulation of nutrients by these plants and weed control. The experiments were conducted in an experimental area of Embrapa Arroz e Feijão, in the 2020, 2021 and 2022 seasons, with a randomized block design, in the 2x8 factorial scheme and four replications. The treatments consisted of the combination of 8 vegetable covers ((1. fallow/weeds), 2. Corn, 3. Mix 1 (White Lupin, Buckwheat, White Oats, Black Oats, C. ochroleuca, C. Juncea, Forage Turnip, Coram Cane); 4. 2 (Buckwheat, C. spectabiliis, turnip, black oat); 5. Mix 3 (Millet, C. ochroleuca, black aveite, white oat, buckwheat, Coracan grass); 6. Mix 4 (C. spectabilis, buckwheat, millet and C. breviflora); 7. Mix (Oats, Buckwheat, Millet, Piatã and C. Ocholeuca); and 8. Mix 6 (Oats black, Turnip Forage, White Lupine, Coracan Grass, Buckwheat)) with or without microorganisms (rhizobacteria Serratia marcencens (BRM 32114) + Bacillus sp. (BRM 63573)). The evaluations consisted of the content of nutrients and dry biomass of the aerial part, using the LSD statistical test (p <0.05). Vegetable toppings, especially corn, mix 4 and mix 5, treated with beneficial rhizobacteria increased the amount of phytomass at 60 days after planting, accumulation of macronutrients N, P, K, Ca and Mg and micronutrients Cu, Fe and Mn compared to the fallow treatment. Higher S content was found in the straws of mix 2 and mix 4 and Zn in corn straws, mix 4 and mix 5, regardless of microbial treatment. In addition, plant covers provided reductions in weed incidence. Therefore, plant cover and multifunctional microorganisms stand out as sustainable technologies, since the improvement of nutritional conditions and the amount of dry biomass of cover crops can directly reflect the availability of nutrients for the successor crop and greater protection and organic matter content for the soil.

RESUMO - Com o objetivo de estudar os efeitos da aplicação de nitrogênio e 2,4-D nos teores de nutrientes nas folhas e grãos, conduziu-se um experimento com a cultura do milho (Zea mays L.) na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul, no município de Guaíba, RS, no ano agrícola de 1981/82. Os tratamentos constaram de duas doses de nitrogênio (40 e 120 kg/ha de N) e quatro doses de 2,4-D (0, 80, 160 e 240 g e.a./ha). Os teores de N, P, K, Ca e Mg nas folhas foram determinados, onze dias após a aplicação de 2,4-D, evidenciou-se efeito significativo somente no teor de potássio, na amostragem realizada onze dias após a sua aplicação. Com 120 kg(ha de N, os teores de N nas folhas foram mais altos do que com 40 kg/ha de N, desde o espigamento ate 60 dias após o espigamento. A dose mais alta de nitrogênio elevou os teores desse nutriente na folha. Além disso, aumentou o teor de fósforo da folha no período do espigamento ate 60 dias após. As percentagens de nutrientes nos grãos não foram afetadas pelas aplicações de nitrogênio e 2,4-D. ABSTRACT - A field experiment was carried out at the Estação Experimental Agronômica/Universidade Federal do Rio Grande do Sul, in Guaíba, RS, Brazil, to evaluate the effects of nitrogen and 2,4-D applications on nutrient contents of com (Zea mays L.) leaves and grains. Treatrnents were composed by two nitrogen levels (40 and 120 kg/ha N) and four 2,4-D levels (0, 80. 160 and 240 g e.a./ha). Nitrogen, phosphorus, potassium, calcium, and magnesium contents in leaves were determined eleven days after 2,4-D appplication and, at twelve day intervals, from silking to 60 days after silking 2,4-D treatments affected significantly only potassium content in leaves, sampled eleven days after its application. With 120 kg/ha N, nitrogen and phosphorus contente in leaves were higher than with 40 kg/ha N, from silking to 60 days after silking. The highest dosis of N per ha increased the N content in the leaves. In addition, it increased the P content in the leaves, from silking to 60 days after silking.
