Abstract
ABSTRACT: The present research aimed to map and estimate the spatial autocorrelation of agricultural crops of coffee, corn, soybeans, sugarcane and beans in the state of Minas Gerais and analyzed in the period from 2011 to 2015. The planted area data were obtained of the Systematic Survey of Agricultural Production - IBGE. The Exploratory Spatial Data Analysis model was used to calculate spatial autocorrelation using the Global and Local Moran Index. Significant spatial self-correction was reported in all studied cultures (P-value <0.05). The regions with the highest concentration of planted area are located in the western portion of the state. The least significant planting regions were the municipalities located in the Jequitinhonha and Vale do Mucuri regions. The results pointed to a micro and mesoregional inequality in the distribution of agricultural activities in the mining territory that seems to reflect the incomplete agricultural modernization process that occurred in the state in the 70 s and 80 s.

The development of the agricultural sector in Brazil can be considered recent when analyzing the country’s economic growth processes that were initiated in the 1950s and 1960s
According to the global Moran’s I, all cultures presented positive spatial autocorrelation, with p
The present study showed that the Triângulo Mineiro/Alto Paranaíba and northwestern mesoregions had the largest DACM values of 6.99% and 6.76% of territorial occupation with soybean cultivation, respectively
Summary
The development of the agricultural sector in Brazil can be considered recent when analyzing the country’s economic growth processes that were initiated in the 1950s and 1960s. From the 1970s onward, the growth of this sector started to become more evident with the spread of the movement known as the Green Revolution, which widely spread the use of agricultural technological packages to increase productivity (CHONCHOL, 2005). In Brazil, the Cerrado biome, which was previously considered unsuitable for agricultural development owing to the edaphic conditions of the soil, benefited from the technological packages in the 1970s, which resulted in soil correction, mechanical irrigation techniques, and the genetic improvement of seeds. The Cerrado Development Program (POLOCENTRO) initiated in 1975, and the Japan-Brazil Agricultural Cooperation Program for the Development of the Cerrado (PROCEDER) established in 1979, are noteworthy for having significantly increased the productivity
