RESUMO: O rabanete é uma planta herbácea de porte reduzido da família brassicaceas, que apresenta ciclo rápido de crescimento. Devido essa característica, é uma planta exigente em nutrientes, devendo ser cultivada em solos férteis. Uma potencial alternativa na fertilização do rabanete é o lodo de curtume, um resíduo de origem animal rico em nutrientes minerais essenciais as plantas. Com intuito de aproveitar os nutrientes contidos nesse resíduo e de conferir uma destinação adequada a esse material, este trabalho objetivou avaliar o lodo de curtume desidratado como adubo alternativo na produção de rabanete. O experimento foi realizado no Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo, Campus Itapina. Utilizou-se um delineamento em blocos casualizados com quatro repetições e seis tratamentos, contendo diferentes proporções de lodo de curtume misturado ao substrato (10%, 25%, 50%, 75% e 100%). O experimento teve duração de 45 dias, onde as plantas atingiram tamanho comercial e foram avaliadas as características de crescimento, matéria seca e os teores de clorofila. O lodo de curtume apresentou potencial de utilização na produção de rabanete como fonte alternativa de fertilização. O intervalo de recomendação desse resíduo na produção de rabanete está situado entre 32,1 e 47,0%, apresentando ganho nas principais características.

CURTUME SLUDGE AS AN ALTERNATIVE FERTILIZER IN THE RADISH PRODUCTION ABSTRACT: Radish is a small herbaceous plant in the brassicaceas family, which has a rapid growth cycle. Due to this characteristic, it is a nutrient-demanding plant and should be cultivated in fertile soils. A potential alternative for fertilizing radish is tannery sludge, an animal residue rich in essential mineral nutrients for plants. In order to take advantage of the nutrients contained in this residue and to provide an appropriate destination for this material, this work aimed to evaluate the dehydrated tannery sludge as an alternative fertilizer in the production of radish. The experiment was carried out at the Federal Institute of Education, Science and Technology of Espírito Santo, Campus Itapina. A randomized block design with four replications and six treatments was used, containing different proportions of tannery sludge mixed with the substrate (10%, 25%, 50%, 75% and 100%). The experiment lasted 45 days, where the plants reached commercial size and the growth characteristics, dry matter and chlorophyll contents were evaluated. The tannery sludge showed potential for use in the production of radish as an alternative source of fertilization. The recommendation interval for this residue in the production of radish is between 32.1 and 47.0%, showing a gain in the main characteristics.

Agricultural Potential

There are many commercial substrates available in the market of vegetables nowadays. However, a growing pressure turned for sustainability in farming, promotes a line of utilization of waste with agricultural potential, such as the use of urban waste compost and tannery sludge, which, when available, can be used as sources of compost and alternative organic matter. The objective of this study was to evaluate the potential of tannery sludge associated with the urban waste compost in the substrate composition of sweet pepper seedlings, especially regarding emergence, development, and quality of seedlings. The experimental design was a randomized block design with six replications and eight treatments. The treatments consisted of mixtures of the residue of dehydrated tannery sludge and urban waste compost, varying in the proportions of 10%, 30%, 50%, 70%, 90% and 100% of each, as well as the use of a commercial substrate as a conventional treatment for the comparisons. Graphs were performed through linear regression analysis for the treatment of statistical data. The percentage of emergence, development, and quality of seedlings were evaluated 54 days after planting. The alternative substrates showed high potential in the production of seedlings, in which all the combinations used in the study were superior to the conventional treatment, except the germination, which did not present difference. The range for the use of tannery sludge in the preparation of substrates for sweet pepper seedlings is between 32.7 and 48.2% in a mixture with urban waste compost. The plants presented better quality with the use of 46.0% of tannery sludge and 54.0% of urban compost in the preparation of the substrate.

Biodiversitas 21: 3929-3937. Bambara groundnut (Vigna subterranea (L.) Verdc.) is a potential grain, which can be considered as an alternative source of protein and carbohydrate. Due to unavailability of commercial bambara groundut cultivar in Indonesia, the characterization of bambara groundnut landraces is an important step before developing cultivar with traits of interest. The objective of the research was to access genetic variability of Indonesian landraces of bambara groundnut with different seed coat colors based on morphological and molecular markers. The experiment was arranged as split-plot in a complete randomized block design with the main plot was cultivation methods and the sub plot was landraces. There were differences in leaf shape and pod shape among the landraces. There were two main clusters of Indonesian landraces of bambara groundnut with 88.28% similarity. The first cluster was Cream, Brown Sumedang, Black Sumedang and Black Tasikmalaya, and the second cluster was Black Sukabumi, Brown Gresik, Black Madura, and Black Gresik. The result based on SSR marker with capillary electrophoresis indicated Black Gresik and Black Madura landraces were different from other Indonesian landraces. Cream Sumedang or Brown Sumedang from the first cluster and Black Gresik or Brown Gresik from the second cluster have the farthest distances for developing improved variety of bambara groundnut.

[email protected] RESUMO: O aproveitamento de resíduos para produção de mudas pode ser uma solução acessível em áreas produtoras de mamão, como alternativa ao uso de substratos comerciais. Assim, este estudo avaliou o efeito do lodo de curtume na produção de mudas de mamão cv. Golden THB. Foram testadas as proporções 0, 15, 30, 45 e 60% de lodo de curtume em mistura com substrato comercial, avaliando as características de emergência, biométricas, gravimétricas e de qualidade de mudas. Os resultados foram submetidos ao teste F e Dunnett (p< 0,05). Os substratos com lodo tiveram desempenho similar ao comercial em todas as características de emergência, mas inferiores para altura da muda, área foliar, matéria fresca e seca da parte aérea e raiz e IQD. Para o número de folhas e diâmetro do caule, apenas a proporção de 15% foi semelhante ao substrato comercial. A análise de regressão apontou que o aumento das proporções de lodo de curtume reduziu gradualmente as médias das variáveis analisadas, exceto para percentagem de emergência. Isso pode estar relacionado a salinidade do lodo, além de desequilíbrios nutricionais. Portanto, a mistura de lodo de curtume ao substrato comercial limitou o desenvolvimento e a qualidade das mudas de mamoeiro cv. Golden THB.

GOLDEN THB ABSTRACT: The use of residues for the production of papaya seedlings can mention an accessible solution to the producing areas. Therefore, the objective was to evaluate the influence of portions of 0 to 60% of tannery sludge in a mixture with a commercial substrate, traditionally used in papaya propagation, to evaluate the emergence, biometric, gravimetric and quality characteristics of papaya seedlings. cv. Golden THB. The emergence characteristics had a similar performance between the proposed and commercial substrates. Overall, there were significant differences between treatments with more than 15% tannery sludge and the commercial substrate. Except for the percentage of emergence, significant results were found for regression, with the answer being the indication that gradually with the increase in the portion of the tannery sludge to the commercial substrate, there was a reduction in the characteristics analyzed. Possibly, the effects of high salinity provided this response pattern, in addition to the nutritional imbalance as a result. Despite the good results of the emergence characteristics, in general, the mixture of tannery sludge to the commercial substrate limited the development and quality of papaya seedlings cv. Golden THB, for use only in proportions up to 15% of sludge. Keywords: propagation, alternative waste, sustainability, cost reduction, Carica papaya.

ABSTRACT The objective of this work was to assess the pulp resistance, soluble solids and yield of watermelon fruits grown under different irrigation managements (determined by the ISAREG model) and mulches, and their interactions. After a survey carried out on local producers, two experiments were conducted, using a completely randomized block design in split-plot arrangement with four replications, in the Teaching, Research and Extension Unit (UEPE) of the Federal Institute of Ceara (IFCE), Jaguaribe-Apodi Irrigation District (DIJA), State of Ceara, Brazil. The treatments consisted of four irrigation managements in the plots, M1 (100% of the available-water capacity (AWC) of the soil), M2 (80%), M3 (60%) and M4 (average water depth used by local producers) and four mulch types in the sub-plots, without mulching (C0) with rice husk (C1), white plastic (C2) and black plastic (C3) as mulches. The results were subjected to analysis of variance, and significant results were subjected to regression (irrigation managements), average test (mulches) and trend graphs (interaction between the factors). The irrigation management practiced during the watermelon crop cycle by the local producers of the Irrigation District of Jaguaribe-Apodi (DIJA) in the State of Ceara, Brazil, is not appropriated, since they usually apply more water than the highest water depth determined by the ISAREG model (100% of the AWC). The plants grown under irrigation water depth of 365.20 mm (M1) and soils with mulches of rice husk or white plastic had the highest yields and fruits with better quality of soluble solids and pulp resistance.

Through lectures turned into meetings, the reading project of The hour of the star (1977), by Clarice Lispector, aimed to bring students closer to reading practices. The main points of interest in this paper are the literary reading, the reading mediation, the interaction with the school library, the reading portfolio production and the literature teaching. In order to do this, discussions are mainly based on Colomer (2007), Petit (2008, 2009, 2013), Jauss (1994), Rouxel (2013) e Rezende (2013). The experience resulted in the opening of new teaching and learning possibilities and provoked in the students a greater autonomy to express themselves, to express their opinions regarding the readings; in other words, it was a time when they recognized themselves as literature readers. Keywords: Literary reading. Reading mediation. Reading portfolio. The hour of the star. Clarice Lispector.

The measurement of leaf pigments using non-destructive methods can be influenced by water management conditions and the use of nutrients in cauliflower, not showing adequate correlations with chlorophyll contents. The objective of this study was to evaluate the correlation between the SPAD index and the pigment content in cauliflower leaves managed with different water conditions and the application of silicon (Si). The cultivation was carried out in a protected environment in the city of Maringá, Paraná State from October 2019 to March 2020. It was adopted a randomized block design, with treatments in a 3 x 4 factorial scheme, with three levels of water recharge (40; 70 and 100% of crop evapotranspiration (ETc)) and four doses of Si (0; 50; 100 and 150 kg ha-1), with four replications. Once plants showed developed inflorescence, the SPAD index was determined in the field and the levels of chlorophyll a, chlorophyll b, and carotenoids in the laboratory using leaves from the upper third. The correlation between water recharge and Si fertilization on the SPAD index was determined. The proportion of carotenoids in relation to total pigments was compared under different conditions. Correlation analysis was performed considering silicon fertilization, water recharge, leaf pigments, and the SPAD index. Silicon fertilization reduced the levels of carotenoids in addition to being related to chlorophyll a (100% of ETc) and chlorophyll b (70% of ETc). The correlation of the SPAD index with pigments is variable with the water condition of the crop, in a condition without water deficit, it is related to chlorophyll a and in a condition of 70% replacement of ETc, it is correlated with chlorophyll b.
