Table 3 Effect of the method of biostimulant application on sugarcane yield, total solid content in the juice (Brix), and N content of leaves in plant growth

	Plant growth
	Control	Furrow	Foliar spray
	Stalk yield (Mg ha⁻¹)
	72.0b	68.4b	92.7a
Increase in relation to the control (%)	–	–	28.8
C.V. (%)	4.5
	Brix (°Bx)
	22.2	22.0	22.5
C.V. (%)	3.6
	Total N content in leaves (kg ha⁻¹)
	208	202	211
C.V. (%)	6.3

The harvest was done at 18 months after planting
Average values followed by different letters are distinct by Fisher’s LSD test (p < 0.05). The increase in relation to the control was calculated by 100 * (x − y)/y, where x is the average of treatment and y is the average of control. C.V. (%) is the coefficient of variation of the experiment
