Full textAbstract:
Mango marketing will be profitable for farmers if they are free to determine one of the first buyers in the market and get the maximum profit. But in reality, most mango farmers have a high dependence on selling their crops to middlemen. This is due to farmers' limitations on market information and access to capital. This research aimed at describe variation of first buyers for mango farmers and farmer's behavior in selling mango crops to first buyer parties. This research was conducted by survey research method. Respondents in this study were 50 mango farmers in Sedong District, Cirebon Regency. The data was analyzed using descriptive statistics and crosstabulation analysis. The results show that the variation of first buyers for mango farmers in Sedong District were a) 1 direction: wholesalers, middlemen/traders b) 2 directions: wholesalers, traditional markets; middlemen/traders, traditional markets; middlemen/traders, wholesalers, dan c) 3 directions: wholesalers, exporters, retailers; middlemen/traders, wholesalers, traditional markets. There are mango farmers who have sold to modern retailers, but have stopped doing partnerships because they are unable to fulfill the quality requirements set by modern retailers. However, majority of mango farmers (72%) in Sedong District still sell mango crops to middleman/traders.

Mango has emerged as an important area for diversification and as an alternative cropping pattern due to higher returns and productivity. The study was conducted in three mango growing districts, namely Chapai Nawabganj, Natore, and Rajshahi during 2014-2015 to estimate the financial benefit of shifting cereal lands to mango production, factors influencing shifting decision, and explore related problems of mango cultivation in the study areas. A total of 180 farmers taking 60 farmers from each district were selected through using multistage stratified random sampling for the study. About 49% lands were shifted to mango cultivation from cereal crops which was higher in Chapai Nawabganj (55%) followed by Natore (48%) district. The main reason of this shifting was reported to be higher profit compared to other crops. The average total cost of mango cultivation was Tk. 1, 33,889 per hectare. Higher cost was observed in the 16th-20th year of garden (Tk. 1, 52,010) followed by 11th -15th year (Tk. 1, 48,952). The average yield of mango was found to be the highest in 16th 20th year (26.48 ton/ha) followed by 11-16th year (19.38 ton/ha). Per hectare net return from mango cultivation was Tk. 1, 75,244. Total cost of mango cultivation was 10% higher than Boro-Fallow-T.Aman cultivation. On the other hand, total cost was about 40% lower than Wheat- Jute- T.Aman, Wheat-Aus-T.Aman and Potato-Fallow-T.Aman. The net return from mango cultivation was 75% higher than other cropping patterns. The shifting of cereal lands to mango cultivation was found to be a profitable since the BCR (2.89), net present value (Tk. 33, 71,166) and internal rate of return (39%) were very high. Relative income, farm size and education turned out to be positively significant, whereas age was negatively significant for shifting decision from cereal crops to mango cultivation. Therefore, Farmers should be motivated to cultivate mango in the fallow lands or areas where other crops are not grown well.Bangladesh J. Agril. Res. 42(1): 137-158, March 2017

Full textAbstract:
Horticulture crops take a crucial part of the Indian economy by creating employment, supplying raw materials to different food processing industries. Mangoes are one of the major crops in horticulture. General Infections in Mango trees are common by various climatic and fungal infections, which became a cause for reducing the quality and quantity of the mangos. The most common diseases with bacterial infection are anthracnose and Powdery Mildew. In recent years, it has been perceived that different variants of deep learning architectures are proposed for detecting and classifying the problems in the agricultural domain. The Convolutional Neural Network (CNN) based architectures have performed amazingly well for disease detection in plants but at the same time lacks rotational or spatial invariance. A relatively new neural organization called Capsule Network (CapsNet) addresses these limitations of CNN architectures. Hence, in this work, a variant of CapsNet called Multilevel CapsNet is introduced to characterize the mango leaves tainted by the anthracnose and powdery mildew diseases. The proposed architecture of this work is validated on a dataset of mango leaves collected in the natural environment. The dataset comprises both healthy and contaminated leaf pictures. The test results approved the undeniable level of exactness of the proposed framework for the characterization of mango leaf diseases with an accuracy of 98.5%. The outcomes conceive the higher-order precision of the proposed Multi-level CapsNet model when contrasted with the other classification algorithms such as Support Vector Machine (SVM) and CNNs.

Usually, commodities shift occurs from food crops to commercial crops, such as horticulture with the aim of improving the welfare of farmer’s life. However, a different situation happened in Sedong Subdistrict, Cirebon Regency where mango farmers switched to paddy cultivation which is a non commercial crop. Most mango farmers began to abandon mango cultivation and made paddy cultivation as their main livelihood. Therefore this research aimed at analyzing the factors underlying the farmer’s decisions to abandon or continue mango cultivation and describing the potential and constraints of mango cultivation. Samples taken were 65 farmers in Sedong Subdistrict, Cirebon Regency consisting of 30 present-grower of mango who also experienced paddy cultivation and 35 past-grower of mango who switched to paddy cultivation. The research method used is the survey research method with data analysis using descriptive statistics and crosstabulation analysis with the fisher exact test. The results showed that the factors related to the farmer's decision to abandon or continue mango cultivation consisted of age, farmer's perception of mango cultivation, risk taking attitude, land tenure status, land area, and farmer group membership. Mango farming has easy transportation in the marketing activities provided by traders, as well as ease of access to credit bunt only for large scale farmers. The constraints felt by farmers in conducting mango farming consist of limited capital for small farmers,

Mango (Mangifera indica L.) is one of the most important tropical fruits in the world and currently ranked 5th in total world production among the major fruit crops. As mango is a seasonal fruit, about 20% of fruits are processed for products such as puree, nectar, leather, pickles, canned slices, and chutney. Mango fruit bar, an important product of commerce, is an excellent source of vitamin A and C, potassium fibre and β-carotene. They are very famous mainly because of it tastes like a mango which come handy and is available off season. Mango bars are generally prepared by drying mango pulp with proper amount of sugar and acid. Thus, to standardize the recipe for preparation of good quality mango bar from mango pulp along with cassava and flour.

Full textAbstract:
Mango (Mangifera indica L.) is one of the important commercial crops occupying a prominent place among various fruit crops. Mango malformation is a crucial malady in mango production leading to heavy economic loss. Malformation occurs in vegetative as well as floral tissue, later being virulent leading to loss of entire crop. Fusarium moniliforme is suggested as dominant causal agent of the disease although association of ‘stress ethylene’ with disease occurrence has also been studied. Fungal pathogens responsible for the malady are known to elevate the level of ‘stress ethylene’ in malformed plants. Various reports have been put forward to explain the etiology and control measures of the disease but nature and management of the disease is still a mystery. Hence, the present review aims at offering information regarding aspects of development and management of mango malformation.

Increasing domestic demand for mangoes in recent years has increased rapidly, not only in terms of quantity but also in terms of quality of mango, especially for modern markets. But only a small part of the mango which could entered the modern market. Understanding of farmers' access to markets is needed to increase farmers' capacity as an effort to improve farmers' welfare. The purpose of this research were to: 1) Analyze socioeconomic characteristics of mango farmers in Indramayu Regency; 2) Analyze the mango marketing channelin Indramayu District; 3) Analyze the factors that influence the decision of mango farmers in market selection in Indramayu District. This research is a quantitative research with 130 mango farmers who were taken by using multi stage random sampling. Data were analyzed descriptively as well as logistic regression analysis. The results showed that most of the farmers were in productive age, had completed primary school education, had <100 trees, never participated in the activity, did not join to farmers group and partnership in marketing. Most farmers market their crops to collecting traders. The level of education of farmers, frequency of extension activities, access to information about mango’s market, quality requirements, the percentage of mango of goodquality and the attachment of farmers to certain financing sources are the factors that significantly influence the farmer's decision in choosing the market. The role of farmer groups is needed to collect farmers in marketing their crops with profitable systems for farmers.

O objetivo principal deste estudo foi o desenvolvimento e validação de metodologia de análise de multiresíduos para quantificação de resíduos de pesticidas em manga. Foram analisados 32 pesticidas, sendo dos seguintes grupos: 9 Organofosforados, 17 Organoclorados e 6 triazois sendo que neste mesmo método foi analisado novamente o Organofosforado fention. Os organofosforados foram analisados em cromatógrafo a gás (CG) acoplado ao detector fotométrico de chamas e os organoclorados foram analisados em cromatógrafo a gás (CG) acoplado ao detector de captura de elétrons (ECD). Os triazois foram analisados em cromatógrafo a gás acoplado a espectrômetro de massa (CG/MS). A curva de linearidade para todos os padrões analíticos, foi realizada em triplicata e com 6 diferentes concentrações. As fortificações das amostras foram realizadas em dois níveis de concentração, no limite do método e 10 vezes o limite do método, sendo que a concentração do limite de quantificação do método (LOQ) foi realizada com sete repetições (N= 7) e a concentração de 10 vezes o LOQ foi realizada com N= 5, usando-se mangas tratadas no sistema orgânico (livres de pesticidas). Os métodos desenvolvidos e validados neste estudo apresentaram-se: a) Linear na faixa de: 0,1 - 4,0 µg/mL para o triclorfon e malation; 0,05 2,0 µg/mL para os demais organofosforados; 0,05 1,6 µg/mL para os organoclorados; 0,1 1,0 µg/mL para o paclobutrazol; 0,25 - 2,5 µg/mL para o fention e bromuconazol; 0,5 5,0 µg/mL para o tetraconazol e tebuconazol e 1,0 10 µg/mL para o procloraz e difenoconazol respectivamente, uma vez que o coeficiente de determinação foi maior que 0,99 para todos os ativos. b) Específicos, pois o nível de contaminação e/ou interferente na análise do branco dos reagentes e da amostra testemunha, foram inferiores a 30% do limite de quantificação. c) Exato, Preciso e Repetitivo, pois todos os ativos apresentaram recuperação dentro do intervalo de aceitabilidade de 70 a 120%, com coeficiente de variação porcentual (CV%) inferior a 15% em relação à média global de todos os níveis de fortificação. Foram também analisados os mesmos pesticidas em 15 amostras de mangas compradas nos supermercados de Piracicaba, procedentes do Nordeste do Brasil. Em nenhuma das amostras foram encontrados resíduos acima do limite estabelecido por lei ou acima do limite de quantificação deste método, no caso dos pesticidas não autorizados.The principal objective of this study was the development and validation of a multiresidue analytical methodology for the quantification of pesticide residues in mangos. Quantitative analyses were made for 32 pesticides, from the following classes: organophosphorus (9), organochlorine (17) and triazole (6). The results from the method include the first analysis for the organophosphorus pesticide fenthion. The organophosphorus pesticides were analyzed by a gas chromatograph (GC) coupled to a flame photometric detector, while the organochlorine pesticides were analyzed using a gas chromatograph (GC) coupled to an electron capture detector (ECD). The triazoles were analyzed with a gas chromatograph coupled to a mass spectrometer (GC/MS). For each of the analytes, calibration curves were constructed in triplicate using solutions with six different concentrations, prepared from the analytical standards. Recovery experiments were performed at two levels of fortification, the limit of quantification of the method (LOQ) and 10 times this limit. Seven repetitions (N = 7) were performed at the limit of quantification, and five (N = 5) at the 10 times higher level of fortification. Mangos raised by organic farming methods (free from pesticides) were used for the recovery experiments. The methods developed and validated in this study have the following characteristics: a) linear range: 0.1 4.0 µg/mL for trichlorfon and malathion; 0.05 2.0 µg/mL for the other organophosphorus pesticides; 0.05 1.6 µg/mL for the organochloro pesticides; 0.1 1.0 µg/mL for paclobutrazol; 0.25 2.5 µg/mL for fenthion and bromuconazole; 0.5 5.0 µg/mL for tetraconazole and tebuconazole; and 1.0 10.0 µg/mL for prochloraz and difenoconazole, in each case the coefficient of determination was greater than 0.99. b) Specific: thus the level of contamination and/or intereference in analysis from the reagent blank and the control sample amounted to less than 30% of the limit of quantification. c) Exact, Precise and Repeatable, for each of the analytes the recovery was found to be within the acceptable interval of 70 to 120%, and with a coefficient of variation, expressed as a percentage, of less than 15% in relation to the global average of the results obtained at the two levels of fortification. Analyses were made for the same pesticides in 15 samples of mangos bought from supermarkets in Piracicaba, which were raised in the Northeast of Brazil. None of these samples contained residue concentrations above the limit established by law or, in the case of non-authorized pesticides, above the limit of the quantification of the current methodology.

The oriental fruit fly, Bactrocera dorsalis Hendel, is an economic tephritid that invaded Senegal in 2004 (Vayssieres et al. 2011). This work determined 1) Impact of B. dorsalis on mango crop production and value, and marketing practices, 2) Effect of neem and kaolin on its behavior and development (laboratory and field), and 3) Effect of treated soil with neem seed cake (NSC) and neem seed powder (NSP) on the larval-pupal survival and development (laboratory and field). Results revealed crop value (price/kg) was associated with infestation levels. P<0.0001, crop value decreased in highly infested orchards. Southern Orchards were heavily infested than northern orchards. Early harvest, orchard sanitation, decreasing the purchase quantity, sorting infested mangoes and lowering prices were strategies used by growers and traders. Laboratory bioassays showed females landed and spent time on fruit identically on control and neem. On kaolin there were fewer landings and less time spent. P<0.0001, mean pupae was higher in control than in treated mangoes. In the field, percent of infested mangoes was higher in neem than in control and kaolin. However, the number of emerged flies was higher in the control than in either the neem or kaolin-treated fruit. Treated soil with NSC and with NSP did not have effect on pupation; all larvae pupated in the lab. However, treated soil decreased significantly the number of emerged flies. In the field, there were no significant differences between untreated and treated soil in number of emerged flies.Master of Science in Life Sciences

Full textAbstract:
The determination of crop coefficient (Kc) with adequate methodology is important to quantify regional water requirement. Jatropha (Jatropha curcas L.) Kc is still unknown and this information will be essential to provide reliable irrigation parameters, as well as for crop zoning. The objective of this study was to determine jatropha actual crop evapotranspiration (ETc) and Kc from 1st to 4th growing year, and correlate Kc with leaf area index (LAI) and cumulative thermal unit (CTU). The experiment was performed from March 2012 to August 2015 at \"Luiz de Queiroz\" College of Agriculture (ESALQ)/University of São Paulo (USP), at Piracicaba city, SP, Brazil. The experiment was divided into center pivot, drip, and rainfed treatments. Two large weighing lysimeters (12 m2 each lysimeter) per treatment were used to determine jatropha ETc (one plant per lysimeter). Reference evapotranspiration (ET0) was determined by Penman-Monteith method from a weather station data situated close to the treatments. Daily Kc was determined for the two irrigated treatments by the ration between ETc and ET0 (Kc=ETc/ET0). LAI was determined using the LAI-2200 plant canopy analyzer, which was previously calibrated for jatropha canopy type. In all growing years, LAI was almost zero at the beginning of vegetative stage, increasing until a maximum during productive stage, and decreasing to zero in the leaf senescence stage. Annual ETc trend during the three growing was very similar, which was explained by the different growing periods and the LAI variation. In the 1st year Kc was 0.47 for both treatments. In the 2nd, 3rd, and 4th years Kc ranged from 0.15 to 1.38 for center pivot treatment and from 0.15 to 1.25 for drip treatment. Kc average in 2nd, 3rd, and 4th years during vegetative and productive growing periods was 0.77, 0.93, and 0.82 for center pivot treatment, respectively, and 0.69, 0.79, and 0.74 for drip treatment, respectively. The relationship between Kc and LAI for the center pivot treatment was adjusted to a logarithmical equation with coefficient of determination (R2) and root mean square error (RMSE) of 0.7643 and 0.334, respectively. For the drip treatment R2 was 0.8443 and 0.2079, respectively. In all three years analyzed, Kc related to CTU by a 3rd degree polynomial equation for both treatments.A determinação de coeficiente de cultivo (Kc) com metodologia adequada é essencial para quantificar o consumo hídrico de cultivos em diferentes regiões. Valores de Kc do pinhão-manso (Jatropha curcas L.) ainda não foram determinados e essa informação é muito importante para auxiliar o manejo de irrigação de maneira adequada. O objetivo desse estudo foi determinar a evapotranspiração (ETc) e Kc do 1º ao 4º ano de cultivo do pinhão-manso, e correlacionar Kc com o índice de área foliar (IAF) e a soma da unidade térmica (SUT). O experimento foi realizado de março de 2012 à agosto de 2015 na Escola Superior de Agricultura \"Luiz de Queiroz\" (ESALQ)/Universidade de São Paulo (USP), na cidade de Piracicaba, SP, Brasil. O experimento foi divido nos tratamentos irrigados por pivô central, gotejamento e sem irrigação. Foram utilizados dois lisímetros de pesagem (12 m2 de superfície em cada lisímetro) por tratamento para realizar a determinação de ETc (uma planta por lisímetros). A evapotranspiração de referência (ET0) foi determinado pelo método de Penman-Monteith a partir de dados meteorológicos coletados na estação meteorológica localizada ao lado do experimento. Valores diários de Kc foram determinados nos tratamentos irrigados pela razão entre ETc e ET0 (Kc=ETc/ET0). IAF foi determinado utilizando o equipamento LAI-2200 Plant Canopy Analyzer, que foi previamente calibrado para adequar as características do dossel do pinhão-manso. Em todos os anos avaliados, o IAF foi quase zero durante o início do período vegetativo, aumentando os valores conforme a planta começou a se desenvolver até atingir valores máximos durante o período produtivo, decrescendo os valores até zero no estádio de desenvolvimento de senescência foliar. A variação anual de ETc no 2º, 3º e 4º ano foi muito similar, explicado pelos diferentes períodos de desenvolvimento da cultura e a variação de IAF no ano. No 1º ano, Kc foi 0,47 para os dois tratamentos irrigados. No 2º, 3º e 4º ano, Kc variou de 0,15 a 1,38 no tratamento irrigado por pivô central e de 0,15 a 1,15 no tratamento irrigado por gotejamento. A média dos valores de Kc no 2º, 3º e 4º ano durante os períodos vegetativos e produtivos foi de 0,77, 0,93 e 0,82 no tratamento irrigado por pivô central, respectivamente, e 0,69, 0,79 e 0,74 no tratamento irrigado por gotejamento, respectivamente. A relação entre Kc e IAF mostrou, para o tratamento irrigado por pivô central, um ajuste logaritmo com coeficiente de determinação (R2) e somatória do erro médio ao quadrado (SEMQ) de 0,7643 e 0,334, respectivamente, e 0,8443 e 0,2079 para o tratamento irrigado por gotejamento, respectivamente. Nos três anos analisados, Kc correlacionado com SUT mostrou o melhor ajuste à equação polinomial de 2ª ordem para os dois tratamentos.

The increased interest in biofuels in recent years, coupled with the problem of the need for environmental sanitation in different areas of the economy justify the proposal of this work, which is the reuse of wastewater from swine (SW) in the jatropha crop (Jatropha curcas L.) and its influence on oil acidity - short parameter importance in the production of biodiesel; culture stands out from oilseeds for its oil production capacity and high adaptability in different scenarios. The experiment featured a Jatropha plantation area of 900 m², which were used 216 m² for conducting the experiment, divided into eighteen installments, the research was conducted over three years; each year the plots received six treatments with different proportions of SW with three repetitions each, applications were performed in triplicate with an interval of three months between each application. Seed harvest was done by hand during the entire production plan period from the first application of each year, the oil was extracted with solvent (ethanol), justified because it is cheaper, less toxic and less harmful to the environment, when compared to other organic solvents such as hexane. The acidity was determined by titration process with sodium hydroxide (NaOH) at the end of each experimental cycle; further the composition was determined as the percentage of oils of fatty acids (FA) by gas chromatography. The results showed an inversely proportional reduction of acidity amount of SW applied during the three years analyzed; It was also observed a decrease in linolenic acid concentration due to the increase of the applied dose and in all cycles. Knowing FA unsaturated oils leave them more susceptible to oxidation, reduction FA that may be related to decreased acidity
O aumento do interesse por biocombustíveis nos últimos anos, somado à problemática da necessidade do saneamento ambiental em diferentes áreas da economia, justificam a proposta do presente trabalho, que é o reuso da água residuária da suinocultura (ARS) na cultura do pinhão manso (Jatropha curcas L.) e sua influência sobre a acidez do óleo - parâmetro de suma importância na produção de biodiesel; a cultura se destaca dentre as oleaginosas por sua capacidade de produção de óleo e a alta adaptabilidade em diferentes cenários. O experimento contou com uma área de plantio de pinhão manso de 900 m², da qual foram utilizados 216 m² para condução do experimento, divididos em dezoito parcelas, a pesquisa foi conduzida ao longo de três anos; em cada ano as parcelas receberam seis tratamentos com diferentes proporções de ARS com três repetições cada, as aplicações foram realizadas em triplicata com intervalo de três meses entre cada aplicação. A colheita das sementes foi feita manualmente durante todo o período produtivo da planta a partir da primeira aplicação de cada ano, o óleo foi extraído com solvente (etanol), justificado pelo fato de ser mais barato, menos tóxico e menos nocivo ao meio ambiente, quando comparado a outros solventes orgânicos, como o hexano. A acidez foi determinada pelo processo de titulação com hidróxido de sódio (NaOH) ao final de cada ciclo experimental; foi determinada ainda a composição dos óleos quanto a porcentagem de ácidos graxos (AG), por cromatografia gasosa. Os resultados mostraram uma redução da acidez inversamente proporcional a quantidade de ARS aplicada, nos três anos analisados; observou-se ainda um decréscimo na concentração do ácido linolênico em função do aumento das doses aplicadas e em todos os ciclos. Sabendo que AG insaturados deixam os óleos mais susceptíveis à oxidação, a redução desse AG pode estar relacionada à diminuição da acidez

Full textAbstract:
Uppsatsen syftar till att undersöka ungdomars reception av fenomenet manga/anime på ett etnografiskt arbetssätt, avgränsat med begreppet ungdomskultur. Fokus ligger på två mangayttringar som närmast berör ungdomar: shōjo för flickor och shōnen för pojkar. Resultatet redovisas i tre olika teman: Estetik/Stil, Makt/Könsroller och Berättelser/Myter,vilka tolkas med hjälp av ett raster på textuell, kontextuell och sociohistorisk nivå.Undersökningen är kvalitativ med sju ungdomar som informanter, och empirin består avfältanteckningar, fotodokumentation och intervjuer.Ungdomarnas fascination av mangaserier kan delvis förklaras med att de ritas i ett utstuderat ”filmiskt” maner, med snabba bildväxlingar och många olika bildvinklar, och delvis med att läsaren kan följa protagonistens utveckling under många år, parallellt med sin egen utveckling till ett vuxnare jag. Kulturyttringen uppmuntrar även till eget medskapande och egenamatörmanga-produktion, vilket medför att många ungdomar publicerar sitt eget material,både i pappersform och på internet. Detta gör fenomenet förhållandevis ohierarkiskt.Manga/anime-traditionen är ofta ironisk och lekfull, motiven i den tidiga sekventiellabildkonsten i Japan hämtades från nöjes- och teatervärlden, men under den flamsiga ytan döljsofta allvarliga resonemang. Berättartraditionen kan uppfattas utifrån tre olika modus: vardagligt, humoristiskt och poetiskt. Ungdomarna kan i postmodernistisk anda ta del av det främmande och egendomliga, men kan också; när de själva vill, stänga av och avskärma sigifrån det.Estetiken betecknas av eklekticism, brottstycken, lekfull inställning till form och konventionoch raserandet av hierarkiska traditionerna. Könsroller utmanas med crossdressing, och demanliga protagonisterna ritas ofta med påfallande feminina anletsdrag. Uppsatsen beskriverdetta med bakgrund av queerteoriska tankegångar, där en given norm ifrågasätts. Läsandet avserietidningar har nästan alltid betraktats nedlåtande, med någon form av moralpanik i sitt kölvatten. Detta kan betraktas som en reaktion mot en pågående modernisering. Resultatet av uppsatsen visar inte på någon större förändring i det traditionella könsrollstänkandet, men en viss omformulering pågår.

O conhecimento da demanda hídrica de uma cultura é fundamental para o planejamento da implantação de novas áreas, bem como para a análise da viabilidade econômica de uma cultura em determinada região. A utilização de culturas para fontes de matéria prima alternativa vem sendo altamente estudada nos últimos anos. Dentre muitas, vem se destacando no cenário nacional e mundial a cultura do pinhão-manso (Jatropha curcas L.) para a produção de biodiesel. O consumo de água por parte do pinhão-manso é pouco conhecida, necessitando ser estudada a fim de aprofundar os conhecimentos sobre a cultura e fornecer parâmetros confiáveis para a prática da irrigação. Os objetivos desse trabalho foram determinar a evapotranspiração (ET), a evaporação (E), a transpiração (T), o coeficiente de cultivo (Kc), coeficiente de evaporação (Ke) e coeficiente de cultivo basal (Kcb) do pinhão-manso na fase de formação irrigados por pivô central, gotejamento e sem irrigação na cidade de Piracicaba, SP. O experimento foi realizado na Fazenda Areão da Escola Superior de Agricultura \"Luiz de Queiroz\" da USP durante o período de março de 2012 a abril de 2013. O experimento foi dividido em três tratamentos, sendo: irrigado por pivô central, gotejamento e sem irrigação. A determinação de ET foi realizada por meio lisímetros de pesagem em cada tratamento, contabilizando a variação de massa em função das entradas saídas de água no sistema. A determinação do Kc foi realizada pela razão entre ET e ETo (estimado a partir de dados coletados na estação meteorológicos automática da Fazenda Areão). Por meio de microlisímetros de pesagem, foi determinado E. De posso dos dados de E, foram determinados os valores de T pela diferença de E (determinado no microlisímetro) e ET (determinado no lisímetro). Os valores de Ke e Kcb foram determinados pela razão de E e T por ETo, respectivamente. Os valores de ET variaram, principalmente, em função do método de irrigação. Foi observado uma superioridade dos valores de ET para o tratamento irrigado por pivô central, seguido do tratamento irrigado por gotejamento e sem irrigação. As médias dos tratamentos durante o primeiro ano foram 3,17, 2,82 e 2,82 mm dia-1 para os tratamentos irrigado por pivô central, irrigado por gotejamento e sem irrigação, respectivamente. Essa mesma proporção de ET entre os tratamentos irrigados foi observado nos valores de Kc. A média do período de Kc foi 0,69 e 0,63 para os tratamentos irrigados por pivô central e gotejamento. Essas maiores taxas de ET e Kc do tratamento irrigado por pivô central em relação ao tratamento irrigado por gotejamento foi devido ao método de irrigação por gotejamento ser mais eficiente na utilização de água pelas plantas em relação ao método por pivô central. Nesse método, a água é aplicada de maneira localizada as plantas, diferentemente do método por pivô central, em que a água é aplicada em toda a superfície do solo. Isso faz com que as taxas de E no método por gotejamento seja menor em relação ao pivô central, diminuindo as taxas de ET. De maneira geral, as taxas de E e Ke foram maiores em relação aos valores de T e Kcb durante o período analisado. Isso foi devido as plantas estarem com porte baixo e o solo estar quase por completo exposto as variações atmosféricas, fazendo com que as taxas de E e Ke sejam superiores as de T e Kcb. A média de E e Ke foram 1,85 mm dia-1 e 1,03, respectivamente, e as médias de T e Kcb foram 0,4 mm dia-1 e 0,2, respectivamente.The knowledge of the water demand of a culture is essential for planning of new areas, as well as for the economic viability analysis of a culture in a specific region. The use of crops for alternative feedstock sources has been extensively studied in the last years. Among many, jatropha (Jatropha curcas L.) has been highlighted for biodiesel production in the national and global scenarios. Water consumption by the jatropha is little known, which requires to be studied in order to increase the knowledge and provide reliable parameters for the irrigation practice. The objectives of this study were to determine the evapotranspiration (ET), evaporation (E), transpiration (T), crop coefficient (Kc), evaporation coefficient (Ke) and basal crop coefficient (Kcb) of jatropha in the formation phase irrigated by center pivot, drip and without irrigation in Piracicaba, SP. The experiment was conducted at Areão Farm of Escola Superior de Agricultura \"Luiz de Queiroz\" of USP during March 2012 to April 2013. The experiment included three treatments: center pivot irrigated, drip irrigated and dryland. The determination of ET was made by weighing lysimeters for each treatment, accounting the inputs and outputs of water in the lysimeter system. The determination of Kc was made by the ratio between ET and ETo (estimated from data collected at the automatic meteorological station of Areão Farm). The determination of E was made by microlysimeters and T was determined between the difference of ET and E. Ke and Kcb values were determined by the ratio of E and T by ETo, respectively. ET values varied, mainly, according to the irrigation method. It was observed superiority of ET values for the treatment irrigated by center pivot, followed by the treatment irrigated by drip and without irrigation. The average during the first year was 3.17, 2.82 and 2.82 mm day-1 for the treatment irrigated by center pivot, irrigated by drip irrigated and without irrigation, respectively. The same proportion of ET from irrigated treatments was observed in the values of Kc. In the period, the average of Kc was 0.69 and 0.63 for the treatments irrigated by center pivot and irrigated by drip. These higher rates of ET and Kc of the treatment irrigated by center pivot compared to the treatment irrigated by drip was due to the method of drip irrigation is more efficient in water use by plants in relation to the method irrigated by central pivot. In this method, the water application is made in a localized way, differently in relation to the center pivot method in which water is applied all over the soil surface. This makes E rates given by drip irrigation method lower than the center pivot irrigation method, decreasing its ET averages. In general, rates of E and Ke were higher compared T and Kcb values during the period analyzed. This was explained due the short plants stature and the soil was almost completely exposed to atmospheric variations, causing rates of E and Ke exceed from T and Kcb rates. The average of Ke and E were 1.85 mm day-1 and 1.03, respectively, and the average of T and Kcb were 0.4 mm day-1 and 0.2, respectively.

Full textAbstract:
Nos últimos anos tem aumentado o interesse no uso do pinhão-manso (Jatropha curcas L.) como fonte de óleo para a produção de biodiesel. No entanto, o conhecimento atualmente disponível sobre o consumo hídrico desta cultura é escasso e constitui um dos principais fatores limitantes no seu uso como alternativa agroenergética. Somado a isso, acredita-se que o aumento da produção de biodiesel no mundo irá aumentar a pressão sobre os recursos hídricos, o que torna necessário utilizar a água na agricultura da forma mais eficiente possível. Assim, este estudo teve como objetivo construir seis lisímetros de pesagem direta que serão utilizados para estudar o consumo hídrico do pinhão-manso irrigado por pivô central, gotejamento e sem irrigação. Esses lisímetros foram calibrados e testados quanto a sua sensibilidade a temperatura do ar e vento. Além disso, comparou-se a influência do uso de duas células de carga diferentes na qualidade dos mesmos. Na área de cada tratamento foram instalados dois lisímetros, sendo um utilizando células de carga ALFA® e outro HBM®. Cada lisímetro foi constituído por tanques de aço carbono de 1,955 m de raio interno (12 m2) e 1,3 m de profundidade útil. Estes foram circundados por paredes de concreto, possuíam sistema de drenagem e se encontravam diretamente apoiados sobre três células de carga. Ambos os modelos das células apresentavam capacidade nominal de 10.000 kg, sendo a capacidade combinada do lisímetro de 30.000 kg. Os lisímetros foram calibrados adicionando e, depois, retirando 1.000 kg de massa dos mesmos. Os dados foram usados para ajustar um modelo de regressão linear entre a massa acumulada e a média do sinal de saída das três células de carga. No teste de sensibilidade à temperatura, a massa dos lisímetros foi monitorada por até dois dias consecutivos, sob condição de massa constante e com proteção para não haver interferência do vento. Os dados foram comparados com a temperatura registrada na estação meteorológica e, também, com a temperatura medida pelo datalogger e um termohigrômetro, os quais foram instalados no fosso dos lisímetros. Para a avaliação da sensibilidade ao vento, foram construídos protótipos de árvores usando tubos de PVC e lonas de ráfia. Em cada lisímetro instalou-se uma árvore e, sob condição de massa constante, a massa dos mesmos foi monitorada por seis dias consecutivos. Os dados obtidos foram comparados com a velocidade do vento medida na estação meteorológica. Todos os lisímetros construídos neste estudo apresentaram qualidade suficiente para serem usados na determinação da evapotranspiração em escala horária e diária. Nos lisímetros ALFA®, a resolução final das medidas foi de 0,0013 mm, sendo realizadas com boa precisão, apresentando histerese e baixa acurácia (erro padrão entre 0,27 e 1,04 mm). Os lisímetros HBM® apresentaram resolução final de 0,00088 mm, boa precisão, pouca ou nenhuma histerese e alta acurácia (erro padrão entre 0,03 e 0,1 mm). Todos os lisímetros demonstraram não sofrer influência da temperatura e do vento na determinação da evapotranspiração, embora, em ambos, ALFA® e HBM®, a precisão das medidas foi reduzida linearmente com o aumento da velocidade do vento.Recently, there is an increasing interest in using physic nut (Jatropha curcas L.) as a source of oil for biodiesel production. However, currently knowledge regarding its crop water requirement is scarce and constitutes one of the main gaps that limit its use as an agroenergy alternative. In addition, there is a general agreement that an increase in biodiesel production worldwide will bring additional pressure to water resources, what provokes to use water in agriculture in a more efficient way. So, this study had as objective to construct six direct weighing lysimeter that will be used to study the water use of physic nut conducted under sprinkler and drip irrigation, and without irrigation. These lysimeters were calibrated and tested for its sensibility to air temperature and wind. Furthermore, there was also compared the influence of using two different load cells on their quality. Two lysimeters were installed for each treatment, one using ALFA® load cells and other using HBM®. Each lysimeter was constituted by a steel tank with 1.955 m inner radius (12 m2) and 1.3 m of usable depth. They were encompassed by concrete walls, have a drainage system and were directly supported by three load cells. Both load cell models has a nominal capacity of 10,000 kg, with a lysimeter summed capacity of 30,000 kg. Lysimeters calibration procedure was done by adding and, after it, removing 1,000 kg of mass from then. Data were used to fit a linear regression model between the accumulated mass and the mean output value of the three load cells. For testing the sensibility to temperature, lysimeters mass were monitored till two consecutive days, under constant mass and with a barrier for protecting against wind interference. Data were compared to the temperature measured by the weather station and, also, by that measured by a datalogger and a thermohygrometer, which were installed inside the lysimeters pit. For testing to wind sensibility, there were constructed some trees prototypes using PVC pipes and raffia tarpaulin. One tree was installed on each lysimeter and, under constant mass, lysimeters mass were monitored during six consecutive days. Data were compared to the wind velocity, as measured by the weather station. All the six lysimeters constructed in this study presented adequate quality to be used for the determination of evapotranspiration on hourly and daily basis. For ALFA® lysimeters, the final measurement resolution was 0.0013 mm, being obtained with good precision, hysteresis, and low accuracy (standard error of 0.27 to 1.04 mm). HBM® lysimeters presented a final resolution of 0.00088 mm, good precision, few or no hysteresis, and high accuracy (standard error between 0.03 and 0.1 mm). All lysimeters proved to be not influenced by air temperature and wind on the determination of evapotranspiration, in spite of, in both, ALFA® and HBM® lysimeters, their measurement precision was linearly reduced with an increase in wind velocity.

AbstractFruit crops are high-value agricultural crops and are mostly managed by individual farmers in India unlike in the West where large private corporations are involved in production and exports of fruit crops. India’s fruits production increased significantly from 28.6 million metric tonnes (MMT) in 1991–92 to 96.8 MMT in 2018–19. Among fruits, mango and bananas are the most important crops with 50% share in fruits acreage as well as value dominated by mango.

Full textAbstract:
Mango (Mangifera indica Linn) plays a central role as fruit crop among the horticultural fruits in Mali. Mali is among the largest mango producers in West Africa and among the fastest growing mango exporters in the world. The volume of mangoes produced is estimated at 575000 tons per year. Mango production is an important socio-economic activity in Mali, providing employment in rural areas and income through exportation. The study focused on marketing channels of mango famers in Mali. The secondary data were used to investigate marketing channels of mango in Mali. This paper consists of three parts. In the first part, the socio-economic characteristics of mango farmers in Mali were explained. In the second part, information about the development of Mango production and trade in Mali was given. In the third part, marketing channels of Mango farmers were examined. In general, it is difficult to say that Mango marketing channels operate effectively in Mali. The ineffectiveness of marketing channels occurs mostly at the local market level. It is important to strengthen the marketing infrastructure for Mango's marketing channels in Mali to be more effective. The government of Mali needs to implement a special incentive program, especially for wholesalers, who play an important role in increasing post-harvest losses. There is a need for financial support and training of wholesalers during the transportation, storage and processing of fresh mango. It is also important to extend these supports for mango producers.

Full textAbstract:
This essay presents the process of creating the artistic project at augmented reality “Wish Mango Tree” is configured as a specific site / public intervention for installing in the georeferenced mango trees of the city of Belém a technological device for electronic labeling and the creation of a hollow steel plate at mango tree. This process involves experimentation and creation related to Visual Arts, Design and programming, experienced through a mobile application, being a physical hybrid intervention. “Wish Mango Tree” is inspired by the work “Wish Tree” , a series of art installations in process, started in 1981, by the Japanese artist, and member of the Fluxus group, Yoko Ono. She chooses a tree native to a place, or plants one under her guidance. The public is invited to tie a wish in writing and hang it on the tree. Yoko has already installed this work in some cities in the world. “Wish Mango Tree” proposes an action similar to the public and passers-by of the mango trees in Belém. The project promotes interaction between individuals: humans and mango trees. Digital content can be viewed in the augmented reality app at the site specific where mango leaf wishes can be accessed by anyone. “Mangueira Desejo” seeks to fill a gap or lack identified: the invisibility of mango trees, seeking to use technology to give visibility to a social and ecological problem. The political dimension of the project is revealed in giving visibility to the mango trees, activating the collective memory and provoking questions and commitments from the individuals involved: trees, people, and institutions. This artistic project aimed at experimentation and creation related to Visual Arts and Design, experienced through a mobile application. And evokes the affective memory of its participants, seeking to enhance, strengthen and maintain the identity and cultural memory of Pará through digital media. The project fits into the artistic and cultural area: Visual Arts, with the creation of proposals in the Visual Arts area, through the areas: installation, intervention mechanisms, specific site, urban art, digital art, new media, photography , being a hybrid proposal between art and digital design. In addition to addressing the experience of the visual arts in their technical, formal and conceptual reflections, of creation, diffusion, training and memory. In this sense, the project promotes creation, experimentation and design associated with a historical, social, cultural, sustainable and / or technological context, which can be translated into propositional actions that address graphic design, interactive media, web design/applications, design of games. The mango trees themselves are objects of public interest, the app invites everyone to “hang” their desires on the “Wish Mango Trees ”, promoting the transformation of the mango trees into a receptacle for the aspirations of the people who cross it. The app will promote remotely a network experience that triggers a physical experience in the main mango trees of the square, when approaching a mango tree to start the action, which will give visibility to the cloud of annotations at mango leaves through mobile app.

Full textAbstract:
Chilling-sensitivity is an important agricultural problem in both the U.S. and Israel. Most research attention has focused so far on herbaceous crop plants, even though the problem is also acute in the fruit tree industry. Under BARD funding we made substantial progress in identifying the mechanisms involved in the disruption of photosynthesis following a chill in mango. Our investigation with fruit trees has been substantially accelerated by drawing on our knowledge and experience with herbaceous crops. The four original research objectives, focused or discovering the underlying mechanisms of chill-induced inhibition of photosynthesis in fruit trees, and the main achievements are listed below. [1] Separating stomatal from non-stomatal components of chilling on photosynthesis in fruit trees. We found evidence that the dark chill-induced inhibition of photosynthesis in mango was E combination of both stomatal and mesophyll components. [2] Differentiating photo damage from light-induced photo protection of photosystem II (PSII). Dark chilling exacerbate high light photoinhibition, as a result of primary inhibition in the carbor reduction cycle. Nevertheless, in Israeli orchards we observed chronic photoinhibition of PSII photochemistry in the winter. This photo damage was reversible over a few days if sunlight was attenuated with filters or night temperature rose. Practical implications of this finding deserve further investment. Additional achievement was the development of a new biophysical tool to study macro-structural changes of LHCII particles in intact, attached leaves. [3] Determine the role of oxidative stress in the dark-chilling-induced inhibition, with emphasis on oxygen radical scavenging, lipid peroxidation and redox-controlled carbon-cycle enzymes. We found an increase in lipid peroxidation following a dark chill, and partial protective effects or an antioxidant. However, the photoinhibition observed in mango orchards in Israel during the winter did not appear to be a general oxidative stress. [4] Investigate whether chilling interferes with the diurnal and circadian rhythm of gene expression of key photosynthetic proteins as has been shown for chilling-sensitive crop plants. The results indicated that most of the circadian rhythm in photosynthesis was due to reduced lea: internal CO2 concentrations during the subjective night, as a result of rhythmic stomatal closure Chilling-induced interference with circadian timing in mango, does not play the central role in chilling inhibition of photosynthesis that has previously been demonstrated in certain chilling sensitive herbaceous plants. Practical implications of the research achievements are feasible, but require few more years of research.

Full textAbstract:
Arabidopsis mutants that we have isolated, encode for fertilization-independent endosperm (fie), fertilization-independent seed2 (fis2) and medea (mea) genes, act in the female gametophyte and allow endosperm to develop without fertilization when mutated. We cloned the FIE and MEA genes and showed that they encode WD and SET domain polycomb (Pc G) proteins, respectively. Homologous proteins of FIE and MEA in other organisms are known to regulate gene transcription by modulating chromatin structure. Based on our results, we proposed a model whereby both FIE and MEA interact to suppress transcription of regulatory genes. These genes are transcribed only at proper developmental stages, as in the central cell of the female gametophyte after fertilization, thus activating endosperm development. To test our model, the following questions were addressed: What is the Composition and Function of the Polycomb Complex? Molecular, biochemical, genetic and genomic approaches were offered to identify members of the complex, analyze their interactions, and understand their function. What is the Temporal and Spatial Pattern of Polycomb Proteins Accumulation? The use of transgenic plants expressing tagged FIE and MEA polypeptides as well as specific antibodies were proposed to localize the endogenous polycomb complex. How is Polycomb Protein Activity Controlled? To understand the molecular mechanism controlling the accumulation of FIE protein, transgenic plants as well as molecular approaches were proposed to determine whether FIE is regulated at the translational or posttranslational levels. The objectives of our research program have been accomplished and the results obtained exceeded our expectation. Our results reveal that fie and mea mutations cause parent-of-origin effects on seed development by distinct mechanisms (Publication 1). Moreover our data show that FIE has additional functions besides controlling the development of the female gametophyte. Using transgenic lines in which FIE was not expressed or the protein level was reduced during different developmental stages enabled us for the first time to explore FIE function during sporophyte development (Publication 2 and 3). Our results are consistent with the hypothesis that FIE, a single copy gene in the Arabidopsis genome, represses multiple developmental pathways (i.e., endosperm, embryogenesis, shot formation and flowering). Furthermore, we identified FIE target genes, including key transcription factors known to promote flowering (AG and LFY) as well as shoot and leaf formation (KNAT1) (Publication 2 and 3), thus demonstrating that in plants, as in mammals and insects, PcG proteins control expression of homeobox genes. Using the Yeast two hybrid system and pull-down assays we demonstrated that FIE protein interact with MEA via the N-terminal region (Publication 1). Moreover, CURLY LEAF protein, an additional member of the SET domain family interacts with FIE as well. The overlapping expression patterns of FIE, with ether MEA or CLF and their common mutant phenotypes, demonstrate the versatility of FIE function. FIE association with different SET domain polycomb proteins, results in differential regulation of gene expression throughout the plant life cycle (Publication 3). In vitro interaction assays we have recently performed demonstrated that FIE interacts with the cell cycle regulatory component Retinobalsoma protein (pRb) (Publication 4). These results illuminate the potential mechanism by which FIE may restrain embryo sac central cell division, at least partly, through interaction with, and suppression of pRb-regulated genes. The results of this program generated new information about the initiation of reproductive development and expanded our understanding of how PcG proteins regulate developmental programs along the plant life cycle. The tools and information obtained in this program will lead to novel strategies which will allow to mange crop plants and to increase crop production.
