SUMMARY:

- Sugarcane is one of the main crops produced in the country and with an average

productivity of 75t ha-1, managing its fertility becomes increasingly essential so that the

crop can increase its productive potential. And in order to seek new management alternatives

for fertility with the use of solubilizer bioinputs. The present work will be carried out in an

experimental area at UFSJ, Sete Lagoas campus, in a first ratoon cane field, implemented with

the RB 86-7515 cultivar, early-medium cycle, in the spring-summer of 2020. The objective of

this work was to evaluate the accumulation of dry matter, macro and micronutrients in

sugarcane regrowth as a function of the collection times of the plants, in areas with and

without the use of phosphorus solubilizer applied in the planting furrow. The experimental

design was in randomized blocks with treatments arranged in a factorial scheme 2

(fertilization strategies – with and without bioinputs) x 8 (plant collection times – 3 in the

tillering phase and 3 in the stalk growth and development phase and 2 in the maturation

phase), with 4 replications, with regression analysis being performed for the season and

average test for interaction and fertilization if it is significant through the Scoot Knoot

average test at 5%.We can observe that the presence of phosphorus solubilizing bioinputs

contributes significantly to the better development of the sugarcane field in relation to non

use, it showed an increase in productivity of 10 t ha-1 at the end of the cycle, we can also

observe that it contributed to the anticipation of the cut because the solubilizer contributes to

the availability of nutrients, making the sugarcane field better absorb nutrients from the soil,

accelerating its development.
