Modalities for soil preparation and gypsum application in ultisol: stem productivity of sugarcane

Abstract: ABSTRACT:The study was conducted in an area of expansion of sugarcane at Vale do Paraná factory in Suzanápolis city -São Paulo (SP), in Brazil, in the northwestern region of the State of São Paulo. It was used the sugarcane variety RB92-5345, 1.5m of spacing between rows, in an Ultisol. The study aimed to evaluate the productivity of sugarcane and first ratoon and some soil chemical attributes in function of soil tillage and application or not of gypsum. The experimental design was randomized blocks with six t… Show more

“…In the mean, 0.37 kg of S is exported by the production of one ton of cane (Thangavelu and Rao, 2006) and continuous sugarcane cultivation results in a greater export of this nutrient, increasing the magnitude in the response of ratoon crops, compared to non-application of S in the treatment without gypsum. Another factor favoring the trend of increasing increments in sugarcane productivity is the increase in calcium levels in the deeper soil layers due to the movement of S-SO 4 -2 (Lima et al, 2013).…”
