The experiment aimed to assess the sugarcane productivity grow in different sources of
fertilization supplemented soil with or without use of the organic compost MICROGEO.
The work was installed and conducted in Faculdade de Ciências Agrárias e Veterinárias/UNESP,
Jaboticabal, São Paulo state, Brazil. The design was a randomized block design in a factorial 5x2
(5 forms of fertilization and 2 levels of application of organic fertilizer) with 3 replications.
The experiment cultivation was on April 4th, 2009, with supplementation of the first factor, composed
of the five sources of fertilization: T1 (liming); T2 (filter cake and vinasse); T3 (filter cake, vinasse
and half of the recommended phosphate fertilization); T4 (filter cake, vinasse and complete recommended
phosphate fertilizer); T5 (recommended mineral fertilization). The second factor studied was the use of
organic fertilizer, applied on January 31, 2013. At the harvest moment, on November 13, 2013, the
agricultural productivity (expressed in t ha-1) was determinated and calculated. The obtained results
were subjected to analysis of variance by F test, and when there was significance, the means were compared
by Tukey test at 5% probability. Higher results were found by treatment with filter cake, vinasse and
recommended phosphate fertilizer (T4) due to increased availability of nutrients in the soil, creating a
greater sugarcane growing season. The application of organic fertilizer showed positive effects on the
productivity, for all nutrient sources, since it can promote increased biological activity in the soil,
improving rooting and nutrients absorption by plants, increases the organic matter mineralization and
improves the soil physical structure.
