Published: March 2022

O presente trabalho tem como objetivo analisar a relação da distribuição espacial dos indicadores de escolaridade em função da renda per capita dos setores censitários da Bacia Hidrográfica do Rio Una (BHRU), localizado no município de Ibiúna-SP. Para isso foram utilizadas técnicas de geoestatística, como estimação de Krigagem Ordinária, teste de Kernel, para avaliar a distribuição da renda e a densidade das escolas juntamente com dados do Censo Demográfico de 2010. De acordo com o teste de Pearson, houve correlação das taxas de escolaridade e renda apenas entre a população com mais de 20 anos. Demonstrando que, quanto menor a renda menor o nível de escolaridade da população, coincidindo a distribuição das áreas de menor renda e escolaridade com as áreas de maior vocação agrícola. Portanto, podemos concluir que conhecer o potencial da distribuição da educação em função da renda é uma ferramenta importante para políticas públicas e sociais.

Spatial analysis of education distribution concerning a watershed money income

ABSTRACT: The current study aims to analyze the spatial distribution relationship among schooling indexes, considering the money income of census tracts of the watershed Una river, which is located at Ibiuna, municipality of São Paulo state. The 2010 Population Census and the Ordinary Kriging were used as geostatistical analysis. Kernel test was applied to evaluate schools density. Pearson test demonstrated a correlation between schooling rates and money income on the population older than 20 years, showing that, the smaller the income, the smaller are the schooling levels. Associated with that, the area distribution of the smallest schooling levels are the same with the biggest agricultural vocation. Therefore, in conclusion, understanding the schooling distribution potential in relation to the income is an important management tool for public and social policies.

Published: March 2022

The objective of this research was to evaluate the nutritional status and yield of ‘Prata’ bananas fertilized with different sources for organic management applied to soils with improved fertility. Two cultivars (‘Prata-Anã’ and ‘BRS Platina’), five annual potassium rates (0, 200, 400, 600, and 800 kg ha-1 of K2O) supplied by bovine manure and rock powder, and six evaluation periods (210, 390, 570, 750, 930, and 1.110 days after transplanting – DAT) were laid out in a randomized block design, in a 2 x 5 x 6 factorial arrangement with three replicates. The yield was determined over three cycles. The levels of K and S in leaves increased with increasing rates of K2O interacting with the evaluation periods. The levels of N, P, and Cu increased with increasing rates of K2O. High soil fertility and manure and rock powder applications were not enough to maintain appropriate levels of leaf Mn in ‘Prata-Anã’. The levels of leaf K, S, Cu, and Zn in the cultivar Prata-Anã differed from those of the ‘BRS Platina’. Applying manure and rock powder as organic fertilizers did not increase the yield of ‘Prata-Anã’ and ‘BRS Platina’ banana plants grown on soils with improved fertility during four production cycles.
Keywords: Musa spp.; leaf tissue analysis; yield.

Estado nutricional e produção de bananeiras ‘Prata-anã’ (AAB) e ‘BRS Platina’ (AAAB) com fertilização orgânica

RESUMO: Objetivou-se esta pesquisa avaliar o estado nutricional e o rendimento de bananeiras 'Prata' com diferentes fontes de fertilização para manejo orgânico em solos com fertilidade melhorada. Duas cultivares ('Prata-Anã' e 'BRS Platina'), cinco doses anuais de potássio (0, 200, 400, 600 e 800 kg ha-1 de K2O) fornecidas por meio de esterco bovino e pó de rocha, e seis períodos (210, 390, 570, 750, 930 e 1.110 dias após o transplantio), distribuídos em delineamento de blocos ao acaso, em esquema fatorial 2 x 5 x 6 com três repetições. O rendimento foi determinado por três ciclos. Os teores de K e S nas folhas aumentaram com aumento das taxas de K2O em interação com os períodos de avaliação. Os níveis de N, P e Cu aumentaram com o aumento das doses de K2O. A alta fertilidade do solo e as aplicações de esterco e pó de rocha não são suficientes para manter os níveis adequados de Mn em ‘Prata-Anã’. Os teores de K, S, Cu e Zn na cultivar Prata-Anã diferem de ‘BRS Platina’. O esterco e o pó de rocha como fertilizantes orgânicos não aumentam o rendimento das bananeiras ‘Prata’ cultivadas em solos com fertilidade melhorada durante quatro ciclos de produção.

Published: March 2022

No cenário econômico, estudar o comportamento de preços de produtos, commodities ou indicadores torna possível a realização de previsões, permitindo elaboração de projeções de risco com maior precisão e, quando ocorrem eventos extremos desses preços, perdas, ou até mesmo falências podem ocorrer. Nesse sentido, a Teoria de Valores Extremos (TVE) trata de maneira adequada tais fenômenos. Foram utilizados os dados econômicos do CEPEA - ESALQ compreendida entre o período de 1997 a 2020, organizados em séries de máximos mensais e, para cada série, as distribuições Gumbel, Generalizada de Valores Extremos (GVE) e suas versões não-estacionárias foram consideradas. Pôde-se constatar que as distribuições Gumbel e GVE se ajustaram em todos os meses e os indicadores de qualidade de ajuste atestam que a distribuição Gumbel é a mais adequada em todos os meses. Nos meses de abril a outubro existe uma ligeira menor probabilidade dos preços serem superados e nos meses de novembro a fevereiro são os meses com maior probabilidade de ocorrência de altos preços de boi gordo. Pelo teste de Mann-Kendall constatou-se tendência em todas as séries, a qual foi incorporada na distribuição Gumbel não-estacionária, e o teste de razão de verossimilhanças e AIC mostraram-se favoráveis quanto à modelagem da tendência.

Probabilistic modeling of maximum commodity fat ox prices
for the state of São Paulo

ABSTRACT: In the economic scenario, studying the behavior of prices of products, commodities or indicators makes it possible to make forecasts, allowing the elaboration of risk projections with greater precision and, when extreme events of these prices occur, losses or even bankruptcies can occur. In this sense, the Extreme Value Theory (EVT) is more suitable such phenomena. Economic data from CEPEA - ESALQ covering the period from 1997 to 2020 were used, organized in series of monthly maximums and, for each series, the Gumbel, Generalized Extreme Values ​​(GVE) distributions and their non-stationary versions were considered. It could be seen that the Gumbel and GVE distributions fit in every month and the goodness-of-fit attest that the Gumbel distribution is the most suitable in every month. In the months of April to October there is a slight lower probability of prices being exceeded and in the months of November to February are the months with the highest probability of occurrence of high fat ox prices. The Mann-Kendall test was used for testing the trend in all series, which was incorporated into the non-stationary Gumbel distribution, and the likelihood ratio test and AIC were favorable in terms of trend modeling.
