Produtividade de laranja correlacionada com atributos químicos do solo visando a zonas específicas de manejo

Abstract: A agricultura de precisão determina o exato manejo da lavoura, tendo como base o mapeamento de zonas específicas de manejo do solo. Assim, tentou-se caracterizar o conceito de zona específica de manejo do solo, pelo emprego de correlações espaciais, usando a cokrigagem ordinária entre a produtividade de laranja Valência e atributos do solo, objetivando selecionar o atributo do solo que mais eficientemente fosse relacionado com o aumento da referida produtividade, em malha geoestatística com 120 pontos amostrai… Show more

“…The choice of attributes for the analyzed soil and plants, which are discussed below, was based on factors related to plant productivity (RODRIGUES; CORÁ; FERNANDES, 2012;ALVES et al, 2013;COSTA et al, 2014;BAZZI et al, 2015). Disturbed and undisturbed soil samples were collected, along with samples of plants during the phenological cycle of the crop.…”

“…Defining management zones requires various steps, from data collection to map evaluation, based on which the cultivation area is divided into subareas that have homogeneity with respect to the evaluated attributes (RODRIGUES; CORÁ; FERNANDES, 2012;ALVES et al, 2013;FARID et al, 2013;DALCHIAVON et al, 2013;BAZZI et al, 2015;SANTOS et al, 2015;SARAIVA, 2015). This allows the application of inputs at appropriate rates for improving the productivity of a crop (BREDEMEIER et al, 2013;BAGHERI et al, 2013;COSTA et al, 2014). However, it is common to see variations in sampling methods, laboratory analyses, statistics, and geostatistics, irrespective of their correlation with plant productivity (ALVES et al 2013;BREDEMEIER et al, 2013;URRETAVIZCAYA et al, 2014).…”

Contudo, tais relações aplicadas à cultura da cana-de-açúcar ainda são pouco exploradas.…”
