Maize is one of the most harvested cereals on the planet. In Brazil, it is the country’s second largest grain production after soybean, with a large portion of production destined for animal feed. During the 2019/2020 harvest, 35% of total maize production was exported, 9.5% was destined for industrial processing and only 1.1% for human consumption. Specialty maize are those grains that are not destined for the dry grain commodities market, but have various other uses and are destined exclusively for human consumption. Specialty maize are also considered as an alternative profit source for farmers. From a plant breeding standpoint, maize is greatest example of success when it comes to the exploitation of heterosis and therefore most of the investment in genetic breeding done by private companies is in the development of simple GMO single-cross hybrids. In today’s market, there are rarely any specialty maize cultivars available, creating a niche for public funded research and development centers to exploit with their conventional type cultivars. This article discusses the relevance of the specialty maize market niches and the role of the Maize Genetic Breeding Program of Instituto Agronomico (IAC) in the development of innovations in São Paulo through the launch of conventional cultivars aimed at small and medium producers and niches of specialty maize.

Abstrak: Saat ini kebutuhan jagung dunia semakin meningkat, dengan pemanfaatan yang luas seperti konsumsi manusia, pakan ternak, hingga kebutuhan industri. Menurut data Kementerian Pertanian, Kabupaten Malang merupakan salah satu sentra produksi tanaman palawija khususnya jagung di Indonesia. Namun saat ini berdasarkan data BPS, hasil produksi jagung di Kabupaten Malang mengalami penurunan. Hal ini terjadi karena kapasitas kerja pengolahan tanah yang dilakukan oleh petani Desa Pulungdowo tidak maksimal dikarenakan usia petani yang sudah tidak produktif untuk melakukan pengolahan tanah. Untuk meningkatkan hasil produksi jagung perlu dilakukan peningkatan SDM dan mekanisasi pertanian. Kebutuhan mekanisasi pertanian di Desa Pulungdowo merupakan sebuah alat pengolahan tanah cultivator yang dapat dimanfaatkan sebagai alat penyiang rumput yang juga dapat dimanfaatkan untuk menggemburkan tanah pada lahan kering. Dengan mekanisasi ini mutu pekerjaan pengolahan tanah menjadi lebih baik, selain itu lebih efisien dalam waktu dan biaya yang dikeluarkan. Kegiatan ini melibatkan petani jagung Desa Pulungdowo dan pemateri yang memberikan penyuluhan mengenai pembibitan tanaman jagung yang dilakukan secara persilangan. Metode yang digunakan pada kegiatan PKM ini adalah dengan melibatkan masyarakat dan memberikan solusi substitusi IPTEK berupa mekanisasi pertanian. Tahapan pelaksanaan kegiatan ini adalah rembug desa yang merupakan bentuk dari survei lapangan, pengadaan alat, penyuluhan mekanisasi pertanian dan pembibitan tanaman jagung, penyerahan alat dan pelatihan operasional perawatan mesin, serta evaluasi untuk mengetahui efektivitas alat. Kegiatan ini menghasilkan evaluasi yang menunjukkan bahwa petani jagung Desa Pulungdowo mampu mengoperasikan alat cultivator setelah dilakukan pelatihan penggunaan dan perawatan mesin, sehingga proses pengolahan tanah pertanian jagung yang dilakukan petani Desa Pulungdowo menjadi lebih efisien.Abstract: Currently, the world's need for corn is increasing, with wide use of such as human consumption, animal feed, to industrial needs. According to data from the Ministry of Agriculture, Malang Regency is one of the production centers for secondary crops, especially maize in Indonesia. However, currently based on BPS data, corn production in Malang Regency has decreased. This happens because the working capacity of land cultivation carried out by the farmers in Pulungdowo Village is not optimal due to the age of the farmers who are not productive enough to cultivate the land. To increase the yield of maize production, it is necessary to increase human resources and agricultural mechanization. The need for agricultural mechanization in Pulungdowo Village is a tool for cultivating land for cultivators that can be used as a tool for weeding which can also be used to loosen the soil on dry land. With this mechanization, the quality of soil processing work will be better, besides that it is more efficient in terms of time and costs. This activity involved corn farmers in Pulungdowo Village and presenters who provided counseling on the breeding of corn which was carried out by crosses. The method used in this PKM activity is to involve the community and provide solutions to substitute science and technology in the form of agricultural mechanization. The stages of the implementation of this activity are village consultations which are a form of field survey, procurement of tools, counseling on agricultural mechanization and corn plant nurseries, delivery of tools and training on machine maintenance operations, and evaluation to determine the effectiveness of the tools. This activity resulted in an evaluation showing that the corn farmers in Pulungdowo Village were able to operate the cultivators after training on the use and maintenance of the machines so that the processing of corn farmland carried out by the farmers in Pulungdowo Village became more efficient

Introduction: Daily and outbursts mortality composting have been identified as one of the finest methods for final disposal of animal corpses, but the probable threat of pathogens transmission truly limits its use. Materials and Methods:  In this study we evaluated the quality and microbiological biosafety of a compost produced in daily mortality experimental unit composting at the Universidade Estadual Paulista in the state of Sao Paulo, Brazil. Settled compost sample was evaluated in order to determine the presence and counting of coliforms and Salmonella sp. and the pathotypes of E. coli STEC, EPEC and EHEC using culture and molecular techniques.  The occurrence of frequent soil borne phytopathogenic fungi was also estimated using selective and differential microbiological culture media. Results and Discussion: The occurrence of pathogenic E. coli, Salmonella sp and phytopathogenic fungi were negative. Coliforms level was 3.05 log10/g. Concussions: The results showed that daily mortality composting method is effective to reduce pathogenic microorganisms, however, in order to add the product on crops or plants such as vegetables that are for direct human consumption, additional tests must be performed to assess the presence of viral pathogens and endospores forming bacteria.

Sabendo que a água é um recurso natural essencial para as atividades humanas, estudos relacionados com seu uso racional e sustentável tornam-se fundamentais. Destinada ao consumo humano, a água deve apresentar características físicas, químicas e microbiológicas não prejudiciais à saúde, as quais são delimitadas por órgãos de saúde pública e caracterizadas como padrões de potabilidade. Assim, esta pesquisa teve como objetivo caracterizar a qualidade da água, avaliando características físico-químicas e microbiológicas que merecem consideração para o monitoramento ao analisar amostras diárias em pontos sorteados da rede de distribuição e em final de tratamento de um município do estado de São Paulo, no período de 2007 a 2011. Foram avaliados os parâmetros: residuais de cloro, pH, turbidez, cor aparente, flúor, temperatura da água, ocorrência de coliformes totais e bactérias heterotróficas. Para comparar a qualidade da água na rede de distribuição com sua qualidade na saída dos reservatórios (final de tratamento), considerando simultaneamente todas as variáveis envolvidas, utilizou-se técnicas de análise multivariada, mais especificamente, o teste T2 de Hotelling. Pretendeu-se aprofundar e melhorar a qualidade das informações e, também oferecer um procedimento metodológico não usual na área envolvida. Os resultados apontaram que o padrão de qualidade da água não se alterou entre o final de tratamento até a rede de distribuição (cavaletes das residências), destacando-se também, que esse procedimento multivariado pode ser utilizado como uma técnica de avaliação do padrão de qualidade da água nos diversos municípios e empresas de saneamento.PALAVRAS-CHAVE: Estatística multivariada, características físico-químicas, características climáticas. WATER FOR CONSUMPTION QUALITY COMPARISON IN BOTH DISTRIBUTION NETWORK AND FINAL TREATMENT RESERVOIRS ABSTRACT: Knowing that water is a key natural resource for human activities, studies related to the rational and sustainable use become crucial. Intended for human consumption, the water must have physical, chemical and microbiological characteristics not prejudicial to health, which are defined by public health agencies and characterized as potability standards. Thus, this study aimed to characterize water quality, assessing physical, chemical and microbiological characteristics and monitor it by analyzing daily samples in randomly selected points in the distribution network and the end of treatment of a municipality of Sao Paulo state in the period of 2007 to 2011. We evaluated the following parameters: residual chlorine, pH, turbidity, apparent color, fluoride, water temperature, occurrence of total coliform, and heterotrophic bacteria. To compare water quality in the distribution network with its quality in the reservoirs (end of treatment), while considering all the variables involved, we used multivariate analysis techniques, more specifically, the Hotelling's T2 test. We intended to increase the knowledge on water wuality,improve the quality of information and also offer an unusual methodological procedure in this area. The results showed that the standard of water quality did not change from the end of treatment up until the distribution network (easels residences). The multivariate procedure tested in this study can be used as an evaluation technique towater quality pattern in various municipalities and sanitation companies.Keywords: multivariate procedure, phisicochemical characteristics, climatic characteristics

A total of 4,581 Salmonella strains isolated from nonhuman sources, including foodstuffs associated with foodborne Salmonella outbreaks, from January 1996 through December 2000 were serotyped at the Enteropathogens Laboratory, Instituto Adolfo Lutz, São Paulo, Brazil. Among the 123 different serotypes identified, Salmonella enterica subsp. enterica serotype Enteritidis (Salmonella Enteritidis) was the most prevalent (32.7%), ranking first for almost every kind of source. The next most common serotypes were Salmonella Senftenberg (10.3%), Salmonella Hadar (6.8%), Salmonella Agona (5.1%), and Salmonella Typhimurium (2.4%). Rough strains belonging to the subspecies S. enterica subsp. enterica (4.8%), S. enterica subsp. arizonae (<1%), S. enterica subsp. diarizonae (<1%), and S. enterica subsp. houtenae (<1%) were also detected. Foodstuffs (including poultry meat for consumption) contained 38.1% of the studied Salmonella strains, poultry flocks (from several farms under salmonellosis control by the owners) contained 21.7%, the environment contained 10.6%, sewage contained 9.4%, water contained 6.6%, animal feed contained 4.4%, chill water from poultry-processing operations contained 2.2%, and other sources contained 7.0%. Foodstuffs extensively contaminated with Salmonella strains were poultry meat (40%), cow meat (11%), desserts (8%), mayonnaise (6%), sausage (5%), and unpasteurized shell eggs (4%), and there were several other food sources (26%). Homemade mayonnaise was the most common vehicle for Salmonella foodborne outbreaks, and Salmonella Enteritidis was the serotype most isolated (95%) from that source. According to these data and previously published data concerning Salmonella strains isolated in São Paulo State, almost the same serotypes have predominated among nonhuman sources for the last decade.

Abstract This research presents the evolution of the world corn market during 2010-2016. Worldwide, corn crops are a very important agricultural crop, both for the population and for animal feed. In order to accomplish this research, a series of indicators specific to the world maize market were studied. The most representative indicators analyzed in this research are: the area cultivated with corn worldwide; total maize production worldwide; the total amount of fertilizer used for corn crops; yield per hectare for corn crop; the amount of Nitrogen used per hectare for maize crops; the amount of potassium used per hectare for maize crops; human consumption of corn worldwide; net export of corn and FOB export price. The statistical data used in this research was taken from specialized international sites for agriculture and food. In this research several references are made to the future evolution of the world maize market. The forecast period is 2019-2025. Changes that occur on the world corn market are due to several factors, the most representative of which are: the decisions of the main actors acting on this market and the natural conditions. Quantitative statistical methods have been used to carry out this research.
