- 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
