Abstract

With the objective of establishing DRIS norms for cotton culture – an agricultural product in frank expansion in Brazil and with a significant contribution to that country’s GDP – the present work studied commercial crops of cities in Mato Grosso and Mato Grosso do Sul State, Brazil. The results indicated that the choice of ratio (A/B or B/A) modifies the interpretation of the results, except when the methodology by Elwali e Gascho was used, because the nutritional index converge regardless of the ratio method chosen. The DRIS method optimizes the management of cotton nutritional data, identifying the limiting nutrients in this culture.
