Soares2,5 Valdemar Faquin2,6 ABSTRACT The Brazilian Savanna (Cerrado) ecosystem concentrates most of the area under cotton cultivation in the country, and is characterized, predominantly, by low fertility soils.
Nitrogen (N) is the most extracted nutrient from the soil by most crops, while sulfur (S) fertilization has been little explored in studies with cotton plants.
This study aimed to evaluate the effects of N and S fertilization on the N content of leaf, weight of 30 bolls, productivity, and agronomic efficiency of cotton plants grown in an Oxisol from the Brazilian Cerrado region.
Two independent field experiments were carried out simultaneously in a comple...
