From: Improving potassium use efficiency of sugarcane through the use of polyhalite
Shoot dry matter yield (g shoot−1) of sugarcane as affected by K dosages applied at transplanting from two consecutive harvests (cane-plant and ratoon) and accumulated. Dosage comparison: regression analysis, the * in the R2 indicates differences between dosage at a level of significance of 10%. ns: non-significant. Error bars (T) represent the standard error of the means (n = 4)
