The application of K fertilizer on sugarcane ratoon
production under conservationist system increases the
soil K content promoting an increase in its availability,
reflected in higher stalk yield at the two evaluated ratoon,
improving crop quality with increase in theoretically
recoverable sugar (t ha-1).
After 2 yr evaluation it was not possible to reduce
the fertilizer recommendation for ratoon sugarcane
plants, since the maximum productivities were reached
with doses close to those recommended for the harvest
system in which residues are burned. However, with the
introduction of a conservationist system there was an
increase of stalk yield of 20 t ha-1 in the second ratoon
compared to the first using the same K rate (130 kg ha-1)
applied to soil.
