ABSTRACT: In semi-arid environments, irregular rains hamper the germinative process of seeds of endemic species, requiring the use of pre-germinative treatments that accelerate and standardize germination. Thus, this research work aimed to evaluate the physiological performance of diaspores of A. urundeuva when stored in different conditions (controlled environment - refrigerated and uncontrolled chamber - environment) and subsequently submitted to different pre-germinative physiological conditioning treatments. A completely randomized design was adopted with four replications of 25 diaspores, using two storage conditions (controlled - refrigerated and uncontrolled chamber - environment), four storage periods (0; 45; 90 and 180 days) and four treatments pre-germinative used after storage periods, establishing a 4 × 4 factorial scheme (storage periods × pre-germinative physiological conditioning treatments). Before storage and after each storage and conditioning period, moisture content, percentage and germination speed index (root protrusion), electrical conductivity and damage to diaspore membranes were evaluated. The storage of the diaspores of A.urundeuva for 180 days reduces the physiological potential, regardless of the temperature and RH of the air. Electrical conductivity and membrane damage are efficient biochemical tests to monitor the reduction in the physiological quality of diaspores stored for 180 days, regardless of air temperature and RH. The physiological conditioning carried out after the storage of the diaspores accelerates the germination process, and can be seen as an advantageous technique in the initial establishment of the seedlings.

ABSTRACT: Basil, an annual herbaceous plant with the scientific name Ocimum basilicum L. belonging to the Lamiaceae family is a plant that produces essential oils, which are widely used. In Brazil, the leaves are grown and sold, and can be used fresh, fresh or dried as a condiment or as a flavoring. Its cultivation is an alternative that generates jobs and income for small farmers. Since the cultivation of basil has grown proportionately on the market and the cultivation in different sources of fertilization in a protected environment provides significant gains in production, this research aimed to evaluate the efficiency of organic substrates in the development of basil (Ocimum basilicum L. ). The research was conducted during the period from April 2019 to June 2019, in a greenhouse belonging to the State University of Alagoas. The components used in the preparation of the substrates were: soil with goat manure, soil with bovine manure, soil with avian litter, soil with earthworm humus and sieved soil. Phenological monitoring was carried out weekly. The data obtained were subjected to analysis of variance by the F test, then the significant characters were subjected to the Tukey test at 5% probability using the SISVAR software 5,6. Among the tested sources, the poultry litter is the most suitable for the development of basil (Ocimum basilicum L.), as it showed a significant response to the variables analyzed in this study. The normal soil showed a significant result for the root length variable, which is probably related to the high natural fertility of the soil in the experimental area, thus meeting the needs of the crop.

The addition of probiotic culture confers potential bio functional to food because of the ability to promote health, and the biochemical and physiological effects in the body. The objective was to produce with lactose and lactose-free yogurt with Bacillus subtilis addition and to evaluate the antioxidant potential of water-soluble peptides during the storage period. For yogurt production, a simple factorial arrangement was used to evaluate two types of milk, adding probiotic culture containing B. subtilis UFPEDA 86. The fractions were evaluated (pre-digestion and post-digestion) concerning the antioxidant elimination potential of the radical’s acid 2,2'-azino-bis (3- ethylbenzothiazoline -6-sulfonic acid) (ABTS), 2,2'-diphenyl 1-picrylhydrazyl (DPPH), chelation of copper and iron. In the evaluation of the results, the fractions obtained from the different combinations of milk, probiotic culture and different days presented antioxidant potential and chelating capacity, activities showed a significant increase after the digestion process. In addition, the results demonstrated that the B. subtilis could support the production of bio-yogurt with antioxidant potential.

ABSTRACT: The gravimetric composition of solid wastes is essential for the identification of the best municipal waste management and management program. Therefore, data on the gravimetric composition allow the knowledge of the factors that determine the origin and formation of these residues. The present study aimed to analyze the gravimetric composition and the per capita generation rate of solid household waste. The methodology used consisted in the collection, separation and weighing of the organic and inorganic residue during 14 days in three Alagoan municipalities: Teotônio Vilela, São Sebastião and Arapiraca rural area. In Teotônio Vilela and São Sebastião, one residence per municipality, with 04 residents per household; and in the municipality of Arapiraca were two residences, one with 05 and the other with 04 residents. The calculation of the per capita generation rate was performed after obtaining the values of the weights of the residues, divided by the number of inhabitants of each locality. Regarding the results, in the gravimetric composition of the analyzed samples, half presented the percentage of the organic residue superior to that of the inorganic residue, average of 57,2%, above the national average; and the rate of per capita generation of household solid waste, the highest rate was 0,57kg/hab./day and the lowest was 0,1 kg/hab./day. It is concluded that the differences found are associated to the locality of the residence and habits of the residents. KEYWORDS: organic waste, inorganic residue, gravimetric composition.

ABSTRACT: Most Protium chemical studies mainly investigate essential oils extracted from the resin. However, there is no information regarding the chemical composition of the leaf extract, and when there are no chemical studies on the species, the phytochemical analysis can identify the relevant secondary metabolite groups. In this context, the aim of the study was to identify the secondary metabolites of the ethanolic extract, obtained from the leaves of Protium calendulinum and to investigate their allelopathic potential on Lactuca sativa. P. calendulinum leaves were collected in July 2019, in the vegetation area of ​​the Federal University of Amazonas - UFAM. To obtain the crude ethanolic extract (CEE), 3 liters of 96% ethyl alcohol on 3 kg of leaves were added. The solution was left to stand for 15 days and subjected to distillation in a rotary evaporator at 70° C. The phytochemical prospecting of the CEE as carried out in a qualitative way. CEE spectrophotometric analyzes were also performed, measured in the range of 240 nm to 700 nm. For the allelopathy test, EB was diluted in the following concentrations: 125 mg/L-1, 250 mg/L-1, 500 mg/L-1 and 1000 mg/L-1. The electrical conductivity of the extract concentrations was determined, and the values ​​used to determine the osmotic potential. The allelopathy bioassay was carried out on L. sativa seeds, 50 seeds were placed in Petri dishes and then added 04 mL of the concentrations. For the negative control, distilled water was used. The allelopathic potential was evaluated by means of the germination percentage, IVG (Germination Speed ​​Index), length of the hypocotyl and radicle. After the test, the chlorophyll and carotenoid assay were performed. To assess the effect of concentrations on percentage of germination; IVG; length of the hypocotyl and length of the radicle, linear regression was used, followed by analysis of variance (Test F). The results obtained in the phytochemical prospecting of the extract of P. calendulinum showed the presence of Flavones, Saponins, Catechins, Phenols and Anthocyanins. Coupled with the results of phytochemical prospecting, the spectrophotometric analysis data confirm the presence of a wide variety of metabolites in the range between 240 and 400 nm. For the osmotic potential, the results obtained varied between -0,0003 MPa and -0,0011 MPa, and are in accordance with the tolerance limit. The results demonstrate that the increased concentration of the extract had a significant effect on germination, IVG, hypocotyl and radicle (p <0.01). This effect corroborates the results of phytochemical prospecting, since flavones and saponins in high concentrations affect the germination percentage, delay the speed with which the seeds germinate and reduce the growth of the hypocotyl and radicle. The levels of chlorophyll b decreased as the CEE concentration increased. The results obtained reveal the presence of different classes of secondary metabolites present in the extract of the leaves of P. calendulinum. And, possibly, due to the presence of these compounds, the extract has a high allelopathic potential, affecting the germination and initial growth of L. sativa, even in low concentrations.

O semiárido alagoano se caracteriza por ter uma economia embasada na produção agropecuária. A criação de animais é predominantemente extensiva, entretanto, em função das chuvas escassas e irregulares, é comum o plantio de espécies forrageiras para silagem, fenação e fornecimento em cochos. Apesar do elevado potencial para a produção, as condições edafoclimáticas e a ausência ou uso de práticas incorretas para manutenção e conservação do solo são fatores que condicionam o bom resultado, e podem ocasionar um declínio na produção e a degradação do solo e da pastagem. A degradação de pastagens surte efeitos negativos na produção animal, afetando diretamente a quantidade e a qualidade das forrageiras. Alterações nos atributos químicos, físicos e biológicos do solo sob pastagens servem como indicativos da qualidade ambiental. A avaliação desses atributos, associada a indicadores visuais de campo (cobertura vegetal, erosão) fornecem indícios sobre a fertilidade do solo e a sustentabilidade do pasto. Nessa perspectiva, avaliou-se uma capineira cultivada com milho forrageiro irrigado no município de Santana do Ipanema – Al. O solo e a água usada para a irrigação foram coletados para análises laboratoriais, e em campo, procedeu-se o levantamento da cobertura vegetal através do método do quadrado. Um questionário foi aplicado para resgatar o histórico de uso e manejo da área. Esses parâmetros foram correlacionados, e, através do método de Spain & Gualdrón, (1991) avaliou-se o estádio de degradação da capineira. O uso de água salobra - C3S1 com características inapropriadas para irrigação, associada ao uso de insumos e de práticas de manejo do solo e da pastagem implementadas de forma incorreta comprometem a sustentabilidade da produção de forragem na área. Em um sistema vulnerável como o do semiárido, a adoção inadequada de tecnologias pelo produtor, reflexo da ausência de assistência técnica pode promover alterações com impactos ambientais irreversíveis. Os efeitos danosos provocados pelo excesso de sais podem ser vistos nos resultados das análises do solo que apresenta pH 13,8, PST 6,9 e saturação de bases de 100%. A cobertura vegetal total encontrada na área foi de 35%, sendo constituída 8% por milho forrageiro e 27% por ervas daninhas e capim nativo. Esses valores respondem pelo grau muito forte de degradação da capineira. Corroboram o alto índice de áreas descoberta no solo (65%), bem como o resultado negativo na produção do milho forrageiro.

ABSTRACT: Umburana (Commiphora leptophloeos (Mart.) J. B. Gillett) is a species that has wood, forage, ornamental, meliferous and medicinal value. The aim of this study was to identify the spectral pattern of umburana (Commiphora leptophloeos (Mart.) JB Gillett) through geotechnologies. The evaluation of changes in patterns was used the Normalized Difference Vegetation Index (NDVI) and the Moisture Stress Index - MSI in a preserved vegetation area at Municipality of Senador Rui Palmeira, state of Alagoas, Brazil. The research was carried out on a property located at Sítio Queimada Grande, rural country of Senador Rui Palmeira, AL. The area was mapped using images. The entire area was covered, with the identification of the Umburanas-de-Cambão found and with the use of GPS, their georeferencing. The determination of NDVI and MSI was obtained through Google Earth Engine, images from the Sentinel 2 Satellite. In the pedological coverage, 88.25% of the umburanas occurred in Luvissolos Crômicos Órticos Vertissolicos.  As for NDVI, the average values found during the year of the study ranged from 3 to 7. As for NDVI, the average values found during the year of the study ranged from 3 to 7. Of the 127 umburanas identified, 117 are in the preservation area and only 10 occur outside it. NDVI was variable, reaching peaks in the months of greatest amount of rain, between June and July.  As for the MSI averages, there was variation 2 and just over 12 throughout the year, with peaks at 100 days and between 150 and 220 days. The NDVI and SMI presented higher values in the month of February with indexes of 0.3 and 4.5, respectively. Based on the observed correlation between NDVI and temperature, the main mechanism that controls the photosynthetic activity of umburanas is temperature.   Keywords: Preservation, Caatinga, NDVI.

ABSTRACT: Free-range poultry has become an important source of income for small farmers in municipalities at backlands of Alagoas. Despite this, little is known about the real financial performance of the activity as well as its operating costs. In this scenario, the objective of the present study was to verify the effective operational cost of egg production in a hick system at municipalities of Santana do Ipanema and São José da Tapera, Alagoas/BR. Technical visits were make to poultry producers, and simplified field booklets were delivered for taking notes, contemplating productivity indicators such as feed consumption, expenses, investments, revenues, input prices, family consumption, losses, number of animals in production, selling price of the product, in which the research participants received the necessary guidance on filling in this material. The study showed that the producers involved in the research are divided between those who use commercial feed and those who manufacture the feed on the property to feed the chickens. The data obtained showed an average cost of R$ 3.26/dozen eggs produced, driven by the variation in the price of inputs, which are imported from other regions of the country. The collective purchase of inputs can help to reduce the cost of production. KEYWORDS: Effective Operating Cost; Egg Production in Caipira System; Alagoas.
