“…McVaugh) plants, foliar fertilization (200 mL per plant with 0.16 g of N; 0.18 g of P 2 O 5 ; 0.18 g of K 2 O; 0.02 g de Ca; 0.02 g of Cl; 0.02 g of S; 0.02 g of Fe; 0.01 g of Cu; 0.01 g of Zn; 0.004 g of Mn; 0.0001 g of Co and 0.0001 g of Mo) increased the contents of Fe, Zn and P in the leaves, compared to the treatments tested (Esashika;Oliveira;Moreira, 2011). Foliar fertilization affected only the contents of S in the shoots of papaya (Carica papaya L.) seedlings, and the other nutrients (N, P, K, Ca and Mg) were supplied through the organic substrates studied (Albano et al, 2017). According to meta-analysis studies, foliar fertilization with a specific nutrient caused an increase in the leaf content of this nutrient, but studies on its interactions are needed (Ostertag;Dimanno, 2016).…”

Foliar fertilization is an important agricultural technique that has stood out for its ease of use and can contribute to the production of high-quality and -vigor cashew seedlings. The objective of this study was to evaluate the effect of foliar fertilizer rates and time of application on ‘BRS 226’ dwarf cashew seedlings after grafting. The experiment was carried out in a completely randomized design, with five treatments and 24 replicates. Each experimental unit consisted of one plant. The commercial product (NPK 20-20-20) was used at the recommended rate for fruit crops in general, 2.5 g L-1. Foliar fertilizer applications at 45 and 60 days after grafting (DAG), with 50% of the recommended rate (1.25 g L-1), or at 80 DAG, with 100% of the recommended, promoted increments of 9% and 13% in the total dry mass, respectively, in comparison to unfertilized plants. Besides that, at 80 DAG the foliar fertilizer application caused significant difference in the B contents, allowed obtaining better quality ‘BRS 226’ grafted dwarf-cashew seedlings. In the production of grafted seedlings of ‘BRS 226’ dwarf-cashew, it’s recommended to foliar fertilization at 45 and 60 days after grafting, with 1.25 g L-1 of the product based on NPK 20-20-20; or a single dose application 2.5 g L-1 at 80 days after grafting.

“…Pesquisas sobre o desempenho de espécies de árvores pioneiras e a identificação de espécies importantes para a restauração são uteis para o plantio em larga escala (LU et al 2017). Alguns estudos já foram realizados sobre a produção de frutas e espécies madeireiras, por exemplo, considerando que o uso de componentes orgânicos na composição de substratos para mudas é uma alternativa viável para a manutenção dos nutrientes (ALBANO et al 2017).…”

O objetivo deste trabalho foi avaliar os aspectos fitotécnicos de mudas florestais cultivadas em blocos prensados com resíduos agroindustriais e o efeito da inoculação microbiológica sobre as mudas. Confeccionou-se quatro compostos com diferentes proporções de bagaço de cana, torta de filtro, fibra de coco e resíduos aviários. Nos blocos prensados do substrato selecionado foram plantadas sementes de Sesbania virgata, Eucalyptus grandi e Acacia mangium. As sementes de Sesbania virgata e Acacia mangium foram inoculadas com rizóbios e fungos micorrízicos específicos, as de Eucalyptus grandi foram inoculadas apenas com os fungos. Aos 70 dias após a semeadura, foram avaliados parâmetros de colonização micorrízica, nodulação, fitotécnicos e nutrição. O delineamento utilizado foi o de blocos completos casualizados em esquema fatorial 4 x 2. Os dados foram submetidos à análise de variância e teste de comparação de médias. Verificou-se que o sistema de produção de mudas em blocos prensados, confeccionados com resíduos agroindustriais, proporciona melhor desenvolvimento das mudas de Sesbania virgata em relação ao tubete convencional, porém não teve efeito no desenvolvimento de mudas de Acacia mangium em relação ao tubete convencional. A inoculação com rizóbio, isoladamente ou associada com fungos micorrízicos arbusculares na fase de produção de mudas, auxiliou no desenvolvimento da espécie Acacia mangium. A produção de Eucalyptus grandis em blocos prensados de resíduos agroindustriais não proporcionou vantagens sobre o desenvolvimento das mudas em tubetes.Palavras-chave: aproveitamento de resíduos; microrganismos benéficos; produção sustentável. PRODUCTION OF INOCULATED FOREST SHAPES WITH RHIZOBIUM AND MYCORRYZIC FUNGI IN AGRICULTURAL WASTE BLOCKS ABSTRACT: The objective of this work was to evaluate the phytotechnical aspects of plant seedlings in blocks pressed with agroindustrial residues and the effect of the microbiological inoculation on the seedlings. Four doses with different ratios of sugarcane bagasse, filter cake, coconut fiber and avian residues were made. In the pressed blocks of the selected substrate were planted seeds of Sesbania virgata, Eucalyptus grandi and Acacia Mangium. The seeds of Sesbania virgata and Acacia mangium were inoculated with rhizobia and specific mycorrhizal fungi. At 70 days after sowing, mycorrhizal colonization, nodulation, phytotechnical and nutrition parameters were evaluated. The design used was a randomized complete block in a 4 x 2 factorial scheme. It was verified that the system of production of seedlings in pressed blocks, made with agroindustrial residues provides better development of the seedlings of Sesbania virgata in relation to the conventional tube, but did not have effect in the development of seedlings of Acacia mangium in relation to the conventional tube. Inoculation with rhizobia alone or associated with arbuscular mycorrhizal fungi in the seedling production phase assisted the development of the Acacia mangium species. The production of Eucalyptus grandis in pressed blocks of agroindustrial residues did not provide advantages for the development of seedlings in tubes.Keywords: waste use; beneficial microorganisms; sustainable production.

There are many residues that can be used for agriculture, especially as a substrate. However, it is often necessary to fertilize the growing media so that the seedlings can be produced with quality. The objective of this study was to evaluate the use of alternative and commercial substrates associated with different controlled-release fertilizer levels in producing yellow passion fruit seedlings. The experiment was conducted at the Embrapa Acre seedling nursery, with 50% luminosity. We used a randomized block experimental design in a 5 x 3 factorial scheme with 15 treatments, 4 replicates, and 10 plants per plot. The treatments consisted of five controlled-release fertilizer levels (0 kg m-3, 3 kg m-3, 6 kg m-3, 9 kg m-3, and 12 kg m-3) combined with lumps of acerola fruits (LAF), Brazil nut peel (BNP), and commercial (CS) substrates. The evaluated variables were seed height, stem diameter, number of leaves, shoot dry mass (SDM), root dry mass (RDM), total dry mass (TDM), and seedling quality index (SQI). Use of the alternative lumps of acerola fruit (LAF) substrate associated with the 10 kg m-³ level of controlled-release fertilizer promoted the best results. BNP has potential for use as a substrate for passion fruit seedlings, however adjustments are necessary to achieve an adequate composition.
