الوصف: Little is known about the use of alternative substrates for the production of seedlings of species native to the Brazilian Cerrado. Thus, this study aimed to evaluate the effect of different substrate compositions (poultry litter and cattle manure) mixed with sandy soil on the development of Hymenaea stigonocarpa and Tabebuia heptaphylla seedlings. In a nursery in Nova Andradina, two experiments were carried out (one for each species), comparing two organic substrates (poultry litter and cattle manure). In addition to different types of substrates, ten proportions of cattle manure (BM), poultry litter (PL) mixed with sandy soil were tested: BM1 = 100% cattle manure; BM2 = 75% cattle manure + 25% soil; BM3 = 50% cattle manure + 50% soil; BM4 = 25% cattle manure + 75% soil; T5 = 100% soil; PL6 = 100% poultry litter; PL7 = 75% poultry litter + 25% soil; PL8 = 50% poultry litter + 50% soil; PL9 = 25% poultry litter + 75% soil; and Control = 100% commercial substrate. The design used was completely randomized with eight replicates for each treatment, comparing these substrates for each species evaluated. The variables evaluated were seedling emergence percentage; average emergence time; plant height; number of leaves; stem diameter; and dry mass accumulation in the roots and shoots of these plants. In addition to these variables, the concentration of macronutrients in plant shoot was also evaluated. Finally, the addition of cattle manure and poultry litter benefited the development of Tabebuia heptaphylla seedlings, in which substrates EB2, EB3, CF7 and CF8 showed excellent results compared to commercial substrate. On the other hand, Hymenaea stigonocarpa seedlings were not responsive to the use of poultry litter, with emphasis on the use of cattle manure, since substrate EB3 stood out in relation to the others. It is noteworthy that low-cost substrates demonstrated results similar to commercial substrate. ; Pouco se sabe sobre o uso de substratos alternativos para produção de mudas de espécies nativas do Cerrado. ...

مصطلحات موضوعية: Biometria, Esterco bovino e ovino, Palma resistente, Semiárido
الوصف: A palma forrageira é a cultura xerófila com maior potencial de exploração no Nordeste. Porém, a variedade mais produzida, a palma gigante (Opuntia fícus indica (Mill.)), mostrou-se vulnerável à praga cochonilha- -do-carmim, sendo necessários testes com variedades resistentes à referida praga. Objetivou-se, com este trabalho, caracterizar os cladódios da palma forrageira (Nopalea cochenilifera Salm Dyck), variedade miúda, plantada com cladódios de diferentes tamanhos e adubos orgânicos – o bovino e ovino –, irrigada com 2,5L.m-1 linear. O experimento foi conduzido no distrito de Santa Luzia do Seridó, município de Picuí-PB, entre maio e dezembro de 2013. Adotou-se o delineamento em blocos casualizados, com seis tratamentos e três repetições, em esquema fatorial 3x2: três tamanhos de cladódios – 15, 20 e 25 cm – e duas adubações orgânicas – esterco bovino e ovino. Procederam-se as seguintes avaliações: altura da planta, comprimento, largura, perímetro, espessura e área do cladódio a cada trinta dias entre 180 e 210 Dias Após o Plantio (DAP). O esterco ovino obteve maior desempenho para altura de planta. O esterco bovino incrementou as medidas dos cladódios primários. O esterco ovino obteve maior desempenho nas medidas dos cladódios secundários. O cladódio de 25 cm em função do esterco ovino obteve um índice biométrico superior.

الوصف: Soil and substrate solarization is an alternative as an efficient disinfestation method to eliminate pathogens, as it stimulates the development of antagonists, also acting in the control of pests and weeds, in addition to promoting plant growth. This work aimed to test the solarization of 4 substrates based on bovine manure, sheep manure, earthworm humus and commercial substrate, in 5 solarization times (0, 24, 48, 72 and 96h). The substrates were prepared by adding black earth and washed sand, and subjected to solarization on full sun days. After this procedure, the substrates were distributed in plastic trays suitable for the production of seedlings and pepper seeds were planted. The evaluation of the experiment was carried out when the seedlings presented about five definitive leaves. The indicators evaluated were: Plant Height (AP), Neck Diameter (DC), Number of Leaves (NF), Root Length (CR), % Leaf Dry Mass (MSF), % Stem Dry Mass (MSC) and % Dry Root Mass (MSR). The data obtained were submitted to analysis of variance and means compared by the Scott-Knott test and the Tukey test at 5% probability, using the statistical program Sisvar version 5.7. No seedlings with disease symptoms were found throughout the experiment. The commercial solarized substrate had significant differences between the indicators tested, showing greater efficiency in the solarization method. In the dry mass indicators, the tested substrates had significant results with solarization and can be used in family farming. ; La solarización de suelos y sustratos es una alternativa como método eficiente de desinfestación para eliminar patógenos, ya que estimula el desarrollo de antagonistas, actuando también en el control de plagas y malezas, además de promover el crecimiento de las plantas.

الوصف: The production of vegetables is characterized by the high intensity of soil use and its resources. The objective was to evaluate the growth, development, productivity and physicochemical characteristics of radish submitted to doses of organic fertilization. The experiment was conducted in the field under 70% shading conditions. A randomized block design with five repetitions and five treatments (0, 15, 30, 45 and 60 t ha-1 of bovine manure) was used. Plant height, stem diameter, number of leaves and leaf area index were evaluated 35 days after planting. Afterwards the plants were harvested and determinations of dry and fresh biomass of the aerial part and bulbs, bulb length and diameter, total soluble solids content (SS), total titratable acidity (TA), SS/TA ratio, pulp color and bulb skin color were performed. The data obtained were submitted to variance analysis (F test) at 5% significance level and presenting significant effect, regression analysis and Tukey test at 5% probability were performed. The doses 30, 45 and 60 t ha-1 did not differ and resulted in higher values for the variables yield, aboveground dry mass, fresh mass and bulb diameter. It was found that the dose of 30 t ha-1 provided higher aerial dry mass, bulb dry mass and SS/AT ratio. It was verified that fertilization with bovine manure, with dosages between 30 and 45 t ha-1 provided an increase in the culture of radish cv. Saxa cultivated under the conditions of the Brazilian semiarid region. ; La producción de hortalizas se caracteriza por la alta intensidad de uso del suelo y sus recursos.

الوصف: Organic certification in family farming companies, mainly in the Northeast region, currently presents, as an obstacle, the obtaining of fertilizers from organic sources, which make it possible, in addition to meeting the inherent needs of soil management and crops in production, not to compromise economic activity, due to the high costs of obtaining, which can compromise the rural enterprise. Thus, in organic production companies, fertilization must be well managed to enable excellent productive gains, providing nutrients in a rational way, in addition to maintaining the structure of the soil, enabling better water retention. In this sense, the objective was to evaluate doses of bovine manure associated with humic substances to promote nutrition, morphophysiological alterations and production in bell pepper. The experimental units consisted of 4 plants. 12 treatments were evaluated, in 4 cazualized blocks, arranged in a factorial scheme with 4 doses of bovine manure (8,0; 18,0; 28,0 and 38,0 t ha-1) and 3 doses of humic substances in proportion 1 :10 (m:v) corresponding to 0; 8 and 12 kg ha-1, totaling 48 experimental plots. The humic substances influenced the productive characteristics of the pepper, obtaining maximum values of average fruit weight (133,65 g) and fruit diameter (75,73 mm) applying 8 t ha-1 of manure associated with 8 kg ha-1 of humic substances, corresponding to an increase of 13,12 and 5,63% respectively, as well as the maximum value of fruit length (80,94 mm) was obtained by applying 8 t ha-1 of manure associated with 12 kg ha-1 of humic substances (7,03% increase). In terms of production, maximum production of 1,2 kg per plant and 43 t ha-1 was obtained by applying 38 t ha-1 of manure associated with 12 kg ha-1 of humic substances, resulting in a productive increase of 10 and 19,44%, respectively. The maximum nutritional levels of P (2,4 g kg-1) of the leaf were obtained by applying 38 t ha-1 of manure associated with 12 kg ha-1 of humic substances, the maximum levels of K (24,5 g kg-1) were ...

الوصف: Animal waste is widely used in organic production systems. However, these residues can increase antimicrobial determinants in the soil. In this perspective, this study was developed to evaluate the presence of sulfonamide resistance genes in soils from an organic production system that received animal waste as organic fertilizer. Soil samples were collected from four properties with different management practices to increase soil fertility. Three properties use the animal waste from the conventional system and the other use plant residues as soil cover and a legal reserve. The extraction of total DNA from soil was carried out followed by the amplification of genes encoding sulfonamide resistance (sul1 and sul2) by the PCR (polymerase chain reaction) technique. The sul1 and sul2 genes were detected only in soils treated with animal waste. The genes were not detected in soils from the legal reserve and the property that used plant residues as soil cover. These results indicate that the use of animal waste as agricultural fertilizer can increase genes for resistance to antimicrobials in the soil and the composting process may not be enough to eliminate them. This information reiterates the need to implement standards that establish quality parameters for animal waste, considering resistance to antimicrobials, as well as the development of management strategies that reduce the risk of spreading resistance to antimicrobials when these residues are applied to soils. ; Resíduos animais são amplamente utilizados em sistemas de produção orgânicos.

الوصف: The processing of coconut generates residues with a significant volume, whose disposal in the environment causes serious problems. One solution would be to use it after defibration in the production of substrate for seedling production. Based on this, the objective of this work was to identify the amount of coconut fiber associated with bovine dung in the substrate for the formation of papaya seedlings. The experiment was carried out in a randomized block design with 5 replications, with substrates being produced in five ratios of coconut fiber for cattle dung (0: 1; 1: 3; 1: 1; 3: 1; 1: 0 ), sown with papaya formosa and 50 days after sowing, evaluations of shoot length and root system, stem diameter, number of leaves, shoot dry mass, root system, total and water retention capacity in substrate. The data were subjected to analysis of variance and polynomial regression at 5% probability. There was significance only for the parameters of the aerial part of the seedlings. The use of up to 44.38% of the coconut fiber used with 55.62% of cattle dung is recommended for the production of papaya seedlings. ; – O processamento do coco gera resíduos com volumes bastante significativos, cujo descarte no ambiente provoca sérios problemas.

الوصف: The use of rock powders, pure our combined, associated or not with organic sources can be an interesting strategy to improve soil fertility and increase plant productivity. This study aimed to evaluate the productivity of soybean and barley plants subjected to treatments with rock powders siltstone, tephrite, and olivine melilitite, pure or combined, associated or not with cattle manure compared with the conventional treatment. Two experiments with pots were carried out in a greenhouse in Cambisol and Nitisol, where soybeans and barley were cultivated, in succession, in 2019, until seed production. Plant productivity of soybean in conventional treatment was higher than the obtained in most treatments. For this same treatment, barley had greater productivity than that obtained in the other treatments. Among the tested rock powders, the best response of plants, in terms of productivity, was verified in treatments with olivine melilitite and siltstone + olivine melilitite, and poor response in those submitted to pure siltstone and tephrite. The combination of manure with these powders provided an increase in plant productivity, especially in the treatment with manure + siltstone + olivine melilitite, in which plant productivity was close to and, in some cases, higher than the obtained in the conventional treatment. ; El uso de polvos de roca, puros o combinados, asociados o no a fuentes orgánicas, puede ser una estrategia interesante para mejorar la fertilidad del suelo y aumentar la productividad de las plantas.
