Natural biostimulants obtained by plants are intensively used nowadays to improve crop yield and quality. The current study aimed to evaluate the effects of leaf extract of moringa (Moringa oleifera Lam.) (MLE) in modifying baby leaf characteristics of two genotypes of Brassica. The trial was started in October 2020 in a greenhouse; a cultivar of kale ‘Cavolo Laciniato Nero di Toscana’ (CL) and a Sicilian landrace of sprouting broccoli ‘Broccoli Nero’ (BN) were used. The plants, after 15, 30 and 40 days from sowing, were treated with MLE, while the control plants (C) with distilled water. Treatment with MLE modified morphological and nutritional value, but with different behavior in the two genotypes. In fact, in BN the treatment reduced the antioxidant activity (2.2-diphenyl-1-picrylhydrazyl (DPPH)) by 54%, while in CL the treatment increased this parameter by 40%. For the phenolic concentration and the sugar content the values recorded were significantly increased by MLE compared to control plants in CL, where in BN a significant reduction was registered. The CL plants treated with MLE showed a significant reduction (−70%) in nitrate content compared to the control plants; a negative effect was, instead, observed in BN, where the plants treated with moringa showed an increase of 60%. Results of this study showed how the foliar application of MLE was effective in improving various nutraceutical parameters, in particular in kale, because it appears to be a species-specific response.

Comumente o sulfato de alumínio é o coagulante químico utilizado nas Estações de Tratamentos para a clarificação da água, embora produza um lodo tóxico de difícil deposição no ambiente. No entanto, os coagulantes naturais como sementes de Moringa oleífera Lam. têm demonstrado vantagens para tratamento em comparação aos químicos, pela simplicidade de uso e baixo custo. O estudo objetivou analisar a eficiência coagulante da semente de Moringa oleífera na clarificação de água com turbidez e comparar com os parâmetros do coagulante químico sulfato de alumínio. As amostras de água foram coletadas no Córrego Jacu Queimado e as sementes colhidas em um plantio da própria espécie. Foram realizados, em laboratório, etapas sequenciais do experimento: comparação da eficiência da semente verde e seca, determinação da concentração e tempo de exposição da semente à água, comparação de agitação manual e magnética entre elas e do coagulante biológico com o químico, sendo analisados os aspectos físico, químico e biológico antes e após a adição de ambos. Observou-se que apenas a semente seca realiza a clarificação da água em comparação com os resultados das análises da água clarificada com o sulfato, determinando-se que 5 sementes são eficazes para tratar 1 litro de água com turbidez de até 25,0 NTU, considerando-se mais relevante a agitação manual para o efeito de coagulação e o aguardo de 2 horas para o término da decantação. Conclui-se, que a semente de Moringa é um coagulante biológico que se apresenta como alternativa para o tratamento de água com turbidez, porém, ainda não é indicada para a potabilidade. É preciso dar continuidade ao tratamento em busca de processos que visam melhorar a qualidade da água para aproximar-se aos parâmetros aceitáveis para o consumo humano.   Moringa oleífera Lam SEEDS: EFFICIENT USE OF BIOLOGICAL COAGULANT FOR WATER TURBIDITY TREATMENT, COMPARED TO ALUMINUM SULFATE CHEMICAL COAGULANT   ABSTRACT Aluminum sulfate is a chemical coagulant commonly used at Water Treatment Plants for water clarification, although it produces a toxic sludge of difficult deposition in the environment. However, natural coagulants such as Moringa oleíferaLam seeds have evidenced the advantages for the treatment when compared to chemicals, due to either their simplicity in and low cost.  This research aims at reviewing the efficient use of   Moringa oleífera seeds as coagulants for turbid water clarification as well as comparing the parameters of aluminum sulfate chemical coagulants. The water samples were collected at Córrego Jacu Queimado and the seeds were harvested from a crop of its own species. Sequential steps were performed in the lab for this experiment: Comparison of green and dry seeds efficiency, concentration and time of exposition of the seed to water measurements, comparison of manual and magnetic stirring among them and among biological and chemical coagulants, being analyzed physical, chemical and biological aspects before and after adding both of them. It was observed that only the dry seed enables water clarification when comparing the analysis results to sulfate water clarification, it was ascertained that 5 seeds are efficient to treat a liter of 25,0 NTU turbidity in water, considering as more relevant manual stirring for coagulation effect after a two-hour rest for decantation completion. It was concluded that Moringa seed is a biological coagulant presented as an alternative for turbid water treatment, although it is not indicated for drinkability. Further treatment is necessary in order to keep searching for processes that target to improve the quality of water and meeting acceptable parameters for water consumption.   Keywords: Biological Coagulant.

Tobacco which still has a great economic importance in the world and Turkey provides extensive employment opportunities from growing to evaluation stage to a certain part of our people and is produced as a family enterprise for centuries in our various regions. The aim of the study was to determine in the effects of worm fertilizer on Aegean type tobacco yield and some quality parameters. The search was carried out in a farmer field in Saruhanli district of Manisa province in 2019. Saribaglar-407 type tobacco was used as a research material. Experimental design was Randomized Complete Parcel Design with three replications. In this research, plant height (cm), number of the leaves (per/plant), cured leaf yield (kg ha-1), tobacco visual quality, leaf priming position (%), total alkaloid (nicotine) (%), total reducing sugar (%) and chlorine (%) were determined. Plant height, number of the leaves, yield, nicotine, total reducing sugar and chlorine contents were found 126.7 cm, 48 per/plant, 141 kg ha-1, 1.02%, 9.08% and 0.48%, respectively. An increase in the middle stalk position of the plant was recorded with the application of fertilizer and the results were obtained among the appropriate values for tobacco of the Aegean region in terms of chemical composition. Keywords: tobacco, worm fertilizer, yield, nicotine.

The purpose of the study is to discover the best length and the diameter of Moringa oleifera Lam. stem cuttings to produce high quality of seedlings. The study was conducted during March-May 2017 located in the nursery field at Dasan Agung, Mataram, 16 m asl. This study was experimental research with Complete Randomized Design with three three replications, and each contains 5 serial experiment units. The treatment for stem cutting length (25 cm, 50 cm, and 75 cm) was then combined with different stem cutting diameters (3-4 cm, 4.1-5 cm, and 5.1-6 cm). The result shows that combination of 75 cm stem length with stem  diameter of 5.1-6 cm resulted to have the best seedling growth.The longer the cutting (up to 75 cm), the better the growth of the seedling. The thickest stem diameter (5.1-6 cm) resulted better seedling

O objetivo deste trabalho foi avaliar a qualidade química e microbiológica da água de cisternas antes e após o tratamento com sementes de Moringa ou leifera Lam. Como sementes de moringa usadas no trabalho foram compostas no município de Cajazeiras. O coagulante da moringa foi usado em meio aquoso. A água filtrada na obra veio de cisternas construídas no assentamento de Santo Antônio, município de Cajazeiras. A água utilizada foi analisada antes e após o tratamento.Uma análise dos parâmetros: pH, condutividade elétrica, alcalinidade total, provável resíduo e total de dissolvidos foi realizada no Laboratório de Água e Solo e no Laboratório de Microbiologia do Instituto Federal de Educação, Ciência e Tecnologia do Campus da Paraíba, análises de coliformes fecais e Escherichia coli foram mantidos. Todas as estatísticas de substâncias químicas mostram diferenças antes e depois do tratamento. Os controles C1 e C5 apresentam presença de Escherichia coli , os demais são causados pela E. coli .
