 The treatments consist of the application of water (control) and biostimulant at a rate of 450 L ha^{−1}, applied one time at 60 and 90 days after planting and two times (60 plus 90 days after planting, dap)
 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
