Of the essential macronutrients to crops, sulfur (S) is the element less studied, which results in the lack of information for the establishment of critical levels in soils, or even response curves of crops to this nutrient. In fact, soybean cultivation occupies extensive areas in Brazil and the addition of fertilizers requires rational recommendations. The objetive of this paper was to study S response. In Bom Jesus, State of Piauí, from Cerrado vegetation, an experiment was carried out on dystrofic oxisol (latossolo vermelho-amarelo distrófico) soil with five levels of S (zero; 20; 40; 80 and 120 kg ha-1 of S) and three sources of S: Simple Superphosphate (SFS); Elementary Sulfur and Gypsum. In the thrid year of cultivation, great response of S application to soybean, was observed resulting in yields of 3701 kg ha-1 with 120 kg ha-1 of S applied as SFS, 3409 kg ha-1 with 100 kg ha-1 of S as elementary sulfur and 3430 kg ha-1 with 69 kg ha-1 of S as Gypsum. Using mean values, there was a response to soybean production up to 91 kg ha-1 of S, with maximum yield of 3419 kg ha-1. |
