Item Agronomic behavior of banana cultivars in the geographic microregion of Assis, São Paulo, Brazil(2022) Martins, Adriana Novais; Suguino, Eduardo; Araújo, Humberto Sampaio; Firetti, Ricardo; Turco, Patrícia Helena Nogueira; Amorim, Edson PeritoAbstract The characterization of banana cultivars is an important stage, which allows the identification of materials adapted to a particular region. The aim of this study was to evaluate the agronomic performance in the edaphoclimatic conditions of the geographic microregion of Assis, State of São Paulo, during the first three production cycles. The experiment was installed at São José Farm, Palmital, SP, where ten banana cultivars (Grande Naine, IAC 2001, FHIA 02, Bucaneiro, FHIA 17, Calypso, Ambrosia, Thap Maeo, BRS Princesa and Caipira) were evaluated during the three production cycles. The experimental design was in randomized blocks, with four replicates, each plot with 8.75 m2 and 5 plants per plot. The evaluated variables were plant height, pseudostem perimeter, number of leaves at flowering and harvesting, bunch mass, number of hands per bunch, fruit and pulp yield. Results were submitted to analysis of variance, means comparison tests and multivariate clustering or tree clustering analysis. ‘Grande Naine’ and ‘IAC 2001’ cultivars, as well as those of the Cavendish subgroup, are the most suitable for cultivation in the geographic microregion of Assis, SP, considering production performance in the evaluated production cycles. Resumo A caracterização de cultivares de bananeiras constitui etapa importante, que permite identificar materiais adaptados para determinada região. O objetivo foi avaliar o desempenho agronômico nas condições edafoclimáticas da microrregião geográfica de Assis-SP, durante os três primeiros ciclos de produção. O experimento foi instalado na Fazenda São José, Palmital-SP, sendo avaliadas 10 cultivares (Grande Naine, IAC 2001, FHIA 02, Bucaneiro, FHIA 17, Calypso, Ambrosia, Thap Maeo, BRS Princesa e Caipira), durante três ciclos produtivos. O delineamento experimental foi em blocos casualizados, com quatro repetições e parcelas de 8,75 m2, compostas por 5 plantas. As variáveis avaliadas foram: altura, perímetro do pseudocaule, número de folhas no florescimento e colheita, massa do cacho, número de pencas por cacho, produtividade de frutos e polpa. Os resultados foram submetidos à análise de variância, aos testes de comparação de médias e à análise multivariada de agrupamentos ou “tree clustering”. As cultivares Grande Naine e IAC 2001, do subgrupo Cavendish, são as mais indicadas para o cultivo na microrregião geográfica de Assis-SP, considerando o desempenho produtivo nos ciclos avaliados.Item Análise de variáveis estratégicas para o desenvolvimento da agropecuária da região do Pontal do Paranapanema(2012) Firetti, Ricardo; Capanema, Luiza Maria; Fachini, Cristina; Turco, Patrícia Helena Nogueira; Veiga Filho, Alceu de ArrudaThe objective of this study is to identify rural activities with greater capacity to generate employment and income, and the relationship between scientific development and rural training in the Pontal do Paranapanema region in a period of 10 years (2008-2018). We have used the Technological Foresight approach to structure the survey and prospective methods and techniques of multivariate statistical analysis of results. Information has been raised at a panel organized with the participation of 50 experts from the region, and the results showed that levels of technical expertise, supply of technologies and technical assistance are variables which are important to generate employment and future income. In addition, actions of technology transfer are essential in the short run and the R&D with technical training for farmers and workers, in the long run. Production activities related to agribusiness were highlighted for job creation to rural workers. New activities, such as rubber tree, eucalyptus, goats, sheep, crop-livestock integration and ornamental plants were considered important to generate income. O objetivo do trabalho é identificar as atividades rurais com maior capacidade de geração de emprego e renda e as relações existentes entre o desenvolvimento científico e capacitação rural no Pontal do Paranapanema em horizonte temporal de 10 anos (2008-2018). Utilizou-se a abordagem Technological Foresight para a estruturação do levantamento prospectivo e métodos e técnicas de estatística multivariada na análise dos resultados. As informações foram levantadas em um painel estruturado com a participação de 50 especialistas da região. Os resultados demonstram que níveis de capacitação técnica, oferta de tecnologias e assistência técnica são variáveis que têm grande importância para geração de emprego e renda futura. Além disso, ações de transferência de tecnologia são prioritárias no curto prazo e as de P&D com capacitação técnica de produtores e trabalhadores rurais, no longo prazo. Destacaram-se, para a geração de empregos ao trabalhador rural, as atividades de produção relacionadas à agroindústria. Novas atividades como a heveicultura, eucalipto, caprinos, ovinos, integração lavoura-pecuária e plantas ornamentais foram consideradas importantes para a geração de renda.Item Multivariate analysis of vegetative growth and productivity in cultivars of the Cavendish subgroup of the banana(2024) Firetti, Ricardo; Martins, Adriana Novais; Suguino, Eduardo; Turco, Patrícia Helena Nogueira; Araújo, Humberto SampaioABSTRACT The aim of this study was to evaluate agronomic performance in cultivars of the Cavendish banana under the soil and climate conditions of the microregion of Assis in the state of São Paulo over three production cycles. The experiment was set up at the Fazenda São José Farm, Água do Pau d´Alho, in Palmital, São Paulo. The Grande Naine, IAC2001 and FHIA02 cultivars were evaluated, considering the following variables: cultivar; plant height; pseudostem perimeter; number of leaves at flowering and harvest; number of days from planting to flowering, from planting to harvest, and from flowering to harvest; weight of the bunch, stalk and fruit per bunch; number of hands per bunch; productivity of the fruit and pulp; weight and number of fingers on the second hand; weight, length and diameter of the finger; pulp diameter; and weight and thickness of the peel. The data were subjected to multivariate statistical techniques (principal component factor analysis, tree clustering, two-way joining, and correspondence). The results showed the extraction of three principal factors that accounted for 89.63% of the total variance of the characteristics under analysis: banana production (Factor 1), vegetative development (Factor 2), and cultivars and fruit diameter (Factor 3). The productive performance of the FHIA02 cultivar was homogeneous and inferior to that of the other cultivars, as seen in the two-way joining cluster analysis. Only the Grande Naine and IAC2001 cultivars are recommended for cultivation in the micro-region of Assis, São Paulo, with Grande Naine showing the largest fruit and, especially, the largest pulp diameter.Item Multivariate analysis of vegetative growth and productivity in cultivars of the Cavendish subgroup of the banana(2024) Firetti, Ricardo; Martins, Adriana Novais; Suguino, Eduardo; Turco, Patrícia Helena Nogueira; Araújo, Humberto SampaioABSTRACT The aim of this study was to evaluate agronomic performance in cultivars of the Cavendish banana under the soil and climate conditions of the microregion of Assis in the state of São Paulo over three production cycles.
