Abstract

CASTELLANOS-GONZALEZ, Leónides et al. Effect of the filter cake, phosphoric rock and biofertilizer addition to the soil on the phosphorous content and sugar cane seedlings. cultrop [online]. 2016, vol.37, n.4, pp.145-151. ISSN 0258-5936.  http://dx.doi.org/10.13140/RG.2.2.17308.08324.

The sugar cane crop has global importance scale and it can be affected productively by the phosphorous deficit. This work aims to evaluate the effect of filter cake, phosphoric rock, and the Azotofo^® and Ecomic^® biofertilizer addition to the soil on the phosphorous content and the development of sugar cane seedlings CP 5243 variety. The investigation was carried out in pots with a Luvisol soil where two vitroplants of 60 days were planted. The treatments were prepared in a completely randomized design with three repetitions. Nine treatments were evaluated by the addition to the soil of filter cake, phosphoric rock and the biofertilizers in different combinations. The morphometric, biological and agrochemical evaluations were carried out 60 days after planting. The obtained data were submitted to variance analysis. The media were compared by Tukey´s test using the statistical program ASISTAT. The simbiosis of mycorrhizae with sugarcane seedlings was verified both at treatments with Glomus cubense and in which was not applied. The combination of filter cake and phosphoric rock with the biofertilizers Ecomic^® and Azotofos^® increased the number of buds in the sugar cane seedlings. The application of  filter cake+Ecomic®, filter cake+Azotofos^®, phosphoric rock+Ecomic^®, phosphoric rock+Azotofos^® and rock+filter cake+Ecomic^® increases the soluble phosphorous in the studied soil
