The use of renewable residues as a source of nutrients, associated with chemical input, can provide better efficiency, greater amount of nutrients available to the plant and reduce its application. The objective of this study was to evaluate the influence of different organic residues associated with chemical fertilizer (NPK) on sugarcane rooting and yield. The experiment was conducted in a Typic Quartzipsamments soil, located in Campo Grande-MS, Brazil, from October 2010 to September 2013. The
more &raquo; ... plots were 4 x 5 m (20 m2), set in a randomized block design with four replicates. The treatments consisted of poultry litter (10 t ha-1), filter cake (10 t ha-1), vermicompost (10 t ha-1) and vinasse (300 m3 ha-1), all associated with basic NPK fertilizer, and control (only basic fertilization). All sources were applied in the furrows before planting, with the exception of vinasse, which was applied through fertigation. The results showed that treatment with filter cake obtained the highest amount of roots with yield gain in the 1st and 2nd harvests.
