    A inquieta\ue7\ue3o com a prote\ue7\ue3o do meio ambiente e com a conserva\ue7\ue3o dos seus recursos \ue9 progressiva, majoritariamente por causa do cen\ue1rio futuro de insufici\ueancia dos mesmos. Surgiram ent\ue3o, no Brasil, os C\uf3digos Florestais, os quais se destinam ao anteparo dos recursos vegetais e h\ueddricos brasileiros. O atual C\uf3digo Florestal (Lei 12.651/12) instituiu o Cadastro Ambiental Rural, instrumento indispens\ue1vel na obten\ue7\ue3o e no registro dos elementos ambientais de todos os im\uf3veis rurais do pa\ueds. Diante desse quadro, o referido trabalho prop\uf4s-se a coletar e a utilizar os dados ambientais de 100 pequenos im\uf3veis rurais registrados na Secretaria de Desenvolvimento Rural do Munic\uedpio de Pelotas. Esses dados foram utilizados para analisar a conformidade dessas propriedades com o presente C\uf3digo Florestal, equiparando-o com os c\uf3digos precedentes. Avaliaram-se os dados das \uc1reas de Preserva\ue7\ue3o Permanente pela extens\ue3o dos cursos d\u2019\ue1gua e das nascentes e as informa\ue7\uf5es das \ue1reas de Reserva Legal. O desfecho demonstrou que boa parte das propriedades rurais mensuradas se encontra em conformidade com a legisla\ue7\ue3o Florestal vigente. Verificou-se, al\ue9m disso, que o atual C\uf3digo Florestal ocasiona uma preserva\ue7\ue3o dos recursos naturais inferior ao C\uf3digo anterior, tanto para as \uc1reas de Preserva\ue7\ue3o Permanente, quanto para a Reserva Legal. Isso ocorre porque grande parte das propriedades \ue9 classificada como \ue1rea consolidada, o que ocasiona uma redu\ue7\ue3o significativa das \ue1reas de vegeta\ue7\ue3o nativa determinada para a composi\ue7\ue3o dessas \ue1reas.The concern about the protection of the environment and the conservation of its resources is progressive, mainly because of the future scenario of its insufficiency. That is why Forest Codes were created in Brazil, destined to the protection of the Brazilian vegetation and the water resources. The current Forest Code (Law 12.651/12) created the Rural Environmental Registry, an indispensable instrument for obtaining the environmental elements of all rural properties in the country. In the view of this situation, this work proposed to collect and use the environmental data of 100 small rural properties registered in the Rural Development Bureau of the Municipality of Pelotas, obtained through the Rural Environmental Registry, to analyze the compliance of these properties with the present Forest Code, matching it with the predecessor code. The data of the Permanent Preservation Areas was evaluated by the extension of the water courses and springs and the information of the Areas of Legal Reserve. The conclusion showed that most of the rural properties measured are in compliance with the legislation of the current Forest Code. It was also verified that the current Forest Code causes a lower preservation of natural resources than the previous Code, both for the Permanent Preservation Areas and for the Legal Reserve. This event happens because most of the properties are classified as consolidated areas, which results in a significant reduction of the native vegetation ones determined for the composition of these areas

    Este estudo teve como objetivo caracterizar a estrutura do manguezal da Lagoa do Roteiro no estado de Alagoas, atrav\ue9s de par\ue2metros fitossociol\uf3gicos. Para isso, foram tra\ue7ados seis transectos, cada um dividido em tr\ueas parcelas de 400/m2, distanciadas 10 metros entre si. Para a verifica\ue7\ue3o dos fatores abi\uf3ticos foram utilizados term\uf4metro (temperatura) e refrat\uf4metro (salinidade). Foram coletadas ainda tr\ueas amostras de sedimento, a uma profundidade de 20 cm, para a an\ue1lise da granulometria e mat\ue9ria org\ue2nica. Foram mensuradas 449 \ue1rvores, apresentando \ue1rvores de Rhizophora mangle , Laguncularia racemosa e Avicennia schaueriana . A densidade m\ue9dia da vegeta\ue7\ue3o arb\uf3rea foi de 624 ind.ha-1, sendo a esp\ue9cie Rhizophora mangle a que apresentou os maiores \uedndices fitossociol\uf3gicos, com valor de import\ue2ncia de 220,59%. Os valores dos par\ue2metros fitossociol\uf3gicos apresentaram grande amplitude nas parcelas analisadas, ocorrendo desde pl\ue2ntulas at\ue9 \ue1rvores adultas. Os valores de temperatura n\ue3o apresentaram diferen\ue7as significativas entre as m\ue9dias das parcelas franja, intermedi\ue1ria e interior, por\ue9m a salinidade se destacou, apresentando um aumento em rela\ue7\ue3o ao interior do bosque. Houve predomin\ue2ncia de sedimento areno-lodoso no manguezal estudado. Dessa maneira, a an\ue1lise fitossociol\uf3gica revelou elevada diversidade estrutural, em um ambiente onde os fatores abi\uf3ticos contribuem para o estabelecimento das esp\ue9cies arb\uf3reas, e uma elevada contribui\ue7\ue3o da esp\ue9cie Rhizophora mangle em todos os par\ue2metros fitossociol\uf3gicos avaliados no ecossistema.This study aimed to characterize the phytosociological structure of the mangrove in Roteiro Lagoon in the state of Alagoas, through phytosociological parameters. For that purpose, six transects were traced, divided into three 400 m2 plots each, 10 meters apart each other. To check the abiotic factors, a thermometer (temperature) and a refractometer (salinity) were used. Three sediment samples were also collected, at a depth of 20 cm, for the granulometry and organic matter analyses. A total of 449 trees were measured, showing trees Rhizophora mangle , Laguncularia racemosa and Avicennia schaueriana . The average density of the arboreal vegetation was 624 ind.ha-1, with the Rhizophora mangle species showing the highest phytosociological indexes, with a value of 220.59%. The values of the phytosociological parameters showed great amplitude in the analyzed plots, occurring from seedlings to adult trees. The temperature values did not show significant differences between the average of the fringe, intermediate and interior portion, however, the salinity stood out, showing an increase in relation to the interior of the forest. There was a predominance of sandy silt in the studied mangrove forest. Thus, the phytosociological analysis revealed high structural diversity, in an environment where the abiotic factors contribute to the establishment of tree species and a high contribution of the Rhizophora mangle species in all phytosociological parameters assessed in the ecosystem

    Effect of manganese and nitrogen fertilization on the content of some essential micronutrients and composition of fatty acids in winter wheat grain

    Nitrogen fertilization combined with microelements is an effective way to provide nutrients to plants, which are essential for obtaining high-value crops. The aim of this study was to evaluate two N fertilizer rates (150 and 200 kg ha-1 and four Mn fertilizer rates (0.0, 0.5, 1.0, and 1.5 kg Mn ha-1) on the N, Mn, Zn, Cu, and Fe content and composition of fatty acids in winter wheat ( Triticum aestivum L.) grain. An increase in the N fertilizer rate increased (12.7%) the Mn content and decreased (10%) the Cu content of wheat grain. Regardless of N fertilization, foliar application of Mn at 1.5 kg ha-1 contributed to the highest Zn (28.4 mg kg-1) and Fe (58.4 mg kg-1) content in the grain. In an analysis of lipid fractions, the highest value of the coefficient of variation was recorded for C18:0 (16.3%-low variation). Nitrogen and Mn fertilization were most strongly correlated with the Mn content of grain (r = 0.356, r = 0.391, respectively). The 200 kg N ha-1 treatments combined with 1.0 kg ha-1 Mn and 150 kg ha-1 N without Mn were correlated with the content of C:18:0, C18:1c11, C18:1c9, and monounsaturated fatty acids in the grain. The application of 200 kg ha-1 N with 1.5 kg ha-1 Mn was correlated with the Fe, Zn, and Mn content of the grain. The remaining fertilization treatments were correlated with the content of C18:3, C18:2, polyunsaturated fatty acids (PUFA), and the C18:2/C18:3 ratio in the grain. Results indicated that the application of 200 kg ha-1 N beneficially affected the PUFA content in the winter wheat grain and can therefore be used to obtain raw material with increased nutritional value. The human organism does not synthesize PUFA, so they must be taken with food (or supplements); winter wheat grain can be a good source because it contains more than 60% PUFA

    Anthropogenic alteration of available, amorphous, and total iron in an Andisol from dairy slurry applications over a 12-year period

    Iron is one of the most abundant elements in agricultural soils, but it is mostly present in non-assimilable forms. The dynamics of Fe is determined by several factors, such as organic matter (OM). Dairy slurry is used to increase total OM content in soils. The objective of this study was to determine the effect of applying dairy slurry over a 12-yr period on the levels of available, amorphous, and total Fe in an Andisol soil as indicators of pedogenic alteration. The contents of available (Fed), amorphous (Feox), and total (Fet) Fe were evaluated by selective extractions. A completely randomized experimental design with repeated measures was used, which consisted of six treatments (2, 4, 6, 8, 10, 12 yr) of slurry application and four replicates. A control treatment (no slurry application) was also included with permanent Lolium perenne L. and Trifolium repens L. grasslands. Dairy slurries were applied at a maximum rate of 150/m3 ha-1. Slurry application in the soil significantly increased Fed and OM contents up to 8 yr in the A (8.2 g kg-1 and 15.7%) and B (7.49 g kg-1 and 10.3%) genetic horizons under study; there was a positive correlation between Fed and OM. This would indicate that increased OM would accelerate the pedogenesis of this soil. In general, Fed-ox values were low and there was a significant decrease (p 64 0.05) in the 2-, 4-, and 6-yr treatments with values ranging between 1.0 and 0.7 for the Feox:d ratio, indicating increased pedogenesis

    Weather variability and its effects on agricultural and food systems are burgeoning global concerns. This study examined the effects of weather variability in the derived savannah and rainforest agroecologies, on crop yields in Southwest Nigeria, and what it portends for food and nutrition security in the region. The trends in the distribution of rainfall and temperature were analysed using the Sens method. The effects of weather variability on crop yield and inferences on what it portends for food security were determined using a stepwise regression model. The results revealed that rainfall fluctuations decreased the yields of cassava ( Manihot esculenta ) and yam (Dioscorea spp.) in the derived savannah; while a decrease in temperature may support improved yields for maize ( Zea mays ), sorghum ( Sorghum bicolor ) and cowpea ( Vigna unguiculata ). The increase in yields of cocoa ( Theobroma cacao ) and cocoyam ( Colocasia esculenta ) would be hampered by increasing maximum temperatures in the rainforest agroecology. Increasing rainfall and temperature would impact warmer conditions that support rapid crop putrefaction, flooding, droughts, challenging postharvest crop management, pest and disease proliferation, and ultimately, reduced crop yields. On the other hand, perpetually low rainfall and temperature conditions will cause poor seedling emergence and growth, seed and total crop loss. It is, therefore, imperative that effective climate adaptation and mitigation mechanisms be put in place across the agroecologies in the region.La variabilit\ue9 m\ue9t\ue9orologique et ses effets sur les syst\ue8mes agricoles et alimentaires sont des pr\ue9occupations mondiales en plein essor. Cette \ue9tude a examin\ue9 les effets de la variabilit\ue9 m\ue9t\ue9orologique dans les agro\ue9cologies d\ue9riv\ue9es de la savane et de la for\ueat tropicale humide sur les rendements des cultures dans le sud-ouest du Nigeria, et ce qu\u2019elle pr\ue9sage pour la s\ue9curit\ue9 alimentaire et nutritionnelle dans la r\ue9gion. La tendance de la distribution des pr\ue9cipitations et de la temp\ue9rature a \ue9t\ue9 analys\ue9e \ue0 l\u2019aide de la m\ue9thode Sens. Les effets de la variabilit\ue9 m\ue9t\ue9orologique sur le rendement des cultures et les d\ue9ductions sur ce qu\u2019elle pr\ue9sage pour la s\ue9curit\ue9 alimentaire ont \ue9t\ue9 d\ue9termin\ue9s \ue0 l\u2019aide d\u2019un mod\ue8le de r\ue9gression progressive. Les r\ue9sultats ont r\ue9v\ue9l\ue9 que les fluctuations des pr\ue9cipitations diminuaient les rendements du manioc ( Manihot esculenta ) et de l\u2019igname (Dioscorea spp.) dans la savane d\ue9riv\ue9e ; tandis qu\u2019une diminution de la temp\ue9rature pourrait favoriser l\u2019am\ue9lioration des rendements du ma\uefs ( Zea mays ), du sorgho ( Sorghum bicolor ) et du ni\ue9b\ue9 ( Vigna unguiculata ). L\u2019augmentation des rendements du cacao ( Theobroma cacao ) et du cocoyam ( Colocasia esculenta ) serait entrav\ue9e par l\u2019augmentation des temp\ue9ratures maximales dans l\u2019agro\ue9cologie de la for\ueat tropicale. L\u2019augmentation des pr\ue9cipitations et de la temp\ue9rature aurait un impact sur des conditions plus chaudes qui favorisent la putr\ue9faction rapide des cultures, les inondations, les s\ue9cheresses, la gestion des cultures post-r\ue9colte difficile, la prolif\ue9ration des ravageurs et des maladies et, en fin de compte, la r\ue9duction des rendements des cultures. D\u2019autre part, les pr\ue9cipitations et les conditions de temp\ue9rature perp\ue9tuellement basses entra\ueeneront une mauvaise \ue9mergence et croissance des semis, des semis et une perte totale de r\ue9colte. Il est donc imp\ue9ratif que des m\ue9canismes efficaces d\u2019adaptation et d\u2019att\ue9nuation du climat soient mis en place dans les agro\ue9cologies de la r\ue9gion

    Tomato ( Solanum lycopersicum L.) yields have continued to plummet in Kenya due to biotic stresses and reliance on low yielding varieties. This study aimed at determining heterosis and combining ability for fruit yield and yield components among tomato genotypes and select F1 hybrids combining high fruit yield and other market demanded traits under Kenyan conditions. Ten parental genotypes and their 45 F1 hybrids were studied using 10 710 half diallel mating design, excluding the reciprocals and the self\u2019s. The experiment was set up in Kiambu and Kirinyaga Counties in Kenya. Out of 45 F1 hybrids evaluated, 89% had reduced (negative heterosis) days to 50% flowering and 11% days to maturity, compared to their better parents. Higher heterosis (-9%) was recorded on days to flowering in AVTO1429 x Cal J VF) and -5% for maturity in Roma VF x AVTO1314. All the F1 hybrids had positive heterosis for number of trusses per plant and fruit yield. F1 hybrid AVTO1429 x AVTO1314 had the highest positive heterosis of 114.39% for fruit weight per plant yield. The results showed high significant difference among the ten genotypes for general and specific combining ability effects (male x female) for all the traits evaluated. There was additive and non-additive gene action for the traits, which are important aspects in developing a tomato breeding programme.Les rendements de la tomate (Solanum lycopersicum L.) ont continu\ue9 de chuter au Kenya en raison des stress biotiques et de la d\ue9pendance aux vari\ue9t\ue9s qui donnent le faible rendement.

    This study assessed the concentration of selected heavy metals (Lead and Zinc) from surrounding soil of Royal Salt mining company, Enyigba in Abakaliki LGA, Ebonyi State. Soil samples were collected from nine (9) different locations at depths of 0-15 and 15-30cm. Two (2) samples were collected from each of the nine locations, making it total of eighteen (18) samples. Soil analysis carried out were particle size distribution, pH, available Phosphorus, total Nitrogen, Organic Carbon, organic matter, Calcium, Magnesium, Potassium, Sodium, exchangeable acidity, Aluminium, effective cation exchange capacity, base saturation and two selected heavy metals, Lead (Pb) and Zinc (Zn). Results shows that heavy metals were highest in soil around the disposal site of mine waste. The highest value of Pb and Zn was recorded on tailing down (TD) 14.82 and 25.33mg/kg at 0-15cm depth, 7.22 and 18.93mg/kg at 15-30cm depth respectively. The accumulation of Pb and Zn at the mining site (TD) may be due to mining activities, civil, industrial/anthropogenic activities going on around the site. This study recommends regular monitoring of heavy metal concentration in soil within the mining site and their disposal site in order to conform to international standards set by the WHO

    Open Source Automation Software: Stirring Automated to Integrated Library System

    Get PDF
    The explosion of the World Wide Web; dynamic nature of information technologies, such as open source; the increase in electronic resources; and the rising expectations of library users have contributed to the changing nature of the Automated Library System (ALS) since its inception in the 1970s. These changes are reflected in the conceptual differences between the ALS and the Integrated Library System (ILS). The ALS is identified as simply a database to house and retrieve a library\u2019s holdings while ILS is identified as robust clusters of systems involving every process and module related to library operations. This article presents a review on the evolving features of some commonly adopted Open-Source ILS Software (Koha, NewGenLib, Evergreen, PMB and OpenBiblio) which had stirred ALS to ILS, as well as justifications and barriers to the use of open source software in academic libraries

    Effect of Alum-treated Groundnut ( Arachis hypogea ) Shell Meal on Blood Chemistry and Carcass Characteristics of Broiler Chickens

    Effect of alum-treated groundnut (Arachis hypogea) shell (ATGNS) meal was studied on the blood chemistry and carcass characteristics of broiler chickens. Two hundred and forty (240) day-old broiler chicks of Anak strain were used for the study in a completely randomized design for eight weeks. The chicks were allotted into six groups of forty chicks each and further divided into four replicates of ten chicks each.Groundnut shell (GNS) was processed by soaking it in water containing alum in ratio 1kg of groundnut shell: 15 litre of water: 600g of alum for three, four, five and six days. Wheat offal was included at 10% in T1 as positive control, 4% wheat offal and 6% untreated groundnut shell (GNS) in T2 as negative control, and 4% wheat offal with 6% treated GNS in treatments 3, 4, 5 and 6 at three days, four day, five days and six days of processing respectively. Results on haematological parameters were not significantly (p>0.05) different except mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). Birds in T5 performed better than others in mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) with highest values of 123.83% and 41.93pg respectively, while birds in T3 had the lowest values of 115.28% and 39.05pg in the two parameters respectively. There were significant (p<0.05) differences in serum total protein, albumin and globulin, while other parameters measured showed no significant (p>0.05) differences in serum biochemical studies. Birds fed treatment 1 (T1) had the highest values of 3.95 and 2.72g/dl in total protein and globulin respectively, while the lowest values 2.55 and 0.97g/dl were obtained from birds in T6 respectively. Cut-up parts showed significant (p<0.05) differences in head, neck, back and thigh across treatment means with the exception of other parameters considered. The live weights of birds on processed groundnut shell meal, although not significantly (p>0.05) different, were better (p<0.05) than those on untreated groundnut shell meal (T2). Birds in T6 had the highest values (2.95, 4.60 and 12.53%) in head, neck and thigh respectively. The highest weight (18.02%) of back was recorded in T1. Birds in T4 had the highest values of 19.60 and 4.20% in breast muscle and shank respectively, while those in T3 recorded the lowest (14.65%) in breast muscle, and those in T2 had the lowest (3.56%) in shank. The results in conclusion, showed that alum-treated groundnut shell(ATGNS) could replace wheat offal at 6% level of inclusion by improving carcass yield as well as maintainingblood profile of broiler chickens

    Effect of Post-Dehulling Treatments on Anti-Nutritional and Functional Properties of Cowpea ( Vigna Unguiculata ) Flour

    Get PDF
    Recently, cowpea (Vigna unguiculata) has been cited for imparting specific positive health potentiating responses when properly positioned in the diet. However, inherent anti-nutritional factors in cowpea have long been recognized as concerns and require appropriate processing conditions to ameliorate adverse effects. The study focuses on effect of post-dehulling treatments on anti-nutritional and functional properties of cowpea flour. Three genotypes of cowpea (IT99K-573-2-1, IT96D-610, and IT07K-292-10) were dehulled. Dehulled cowpeas were boiled, roasted or autoclaved and prepared into flour. Raw (dehulled) cowpea genotype served as control. Anti-nutritional and functional properties of the products were determined using standard procedures. Antinutrient concentration of cowpeas differed significantly (p 640.05) among genotypes. Tannin, phytate and oxalate concentration ranged from 31.15 to 121.80g/kg, 22.31 to 48.04 g/kg and 0.01 to 0.026g/kg respectively. Coloured beans (IT96D-610), had significantly lower anti-nutritional content than those of white beans (IT99K-573-2-1 and IT07K-292-10). All heat treatments significantly reduced the levels of investigated anti-nutrients compared to their respective control. Water absorption capacity and oil absorption capacity were found in the range of 2.12\u20133.07 mL/g and 1.37-1.73 mL/g, respectively. Swelling power, starch solubility, loose bulk density and packed bulk density varied between 10.79 to 18.42g/g, 0.16 to 1.52g/g, 0.64 to 0.73g/mL and 0.84 to 0.94 g/mL respectively. Colour parameters (L*, a*, b*, hab, C*) showed significant variations among the genotypes. The combined varietal and processing variation induced significant modification in the inherent anti-nutrients and functional properties of dehulled cowpea as attested by the highly significant (p 640.05) correlations observed. Processing of cowpea seeds in these forms presents an opportunity for extending their use beyond the dehulled seeds in food system
