In order to evaluate the effect of VIUSID agro on the yield response of a pak choi harvest,a randomised block experiment was designed with four treatments and three replications.The treatments were dosages of 0.1,0.2 and 0.3 L/ha and one control.The number of leaves per plant and the fresh and dry mass of the plant were measured.In addition,growth indexes were evaluated,such as relative growth rate,active growth rate,harvest index and agricultural yield.The number of leaves per plant was significantly greater at 35 days after sowing(das)for 0.2 L/ha and 0.3 L/ha treatments,with increases of 15.0%and 14.17%relative to the control.Regarding plant length and fresh mass at the final evaluation,the treatments using higher dosages produced the best results.Regarding the active growth rate,the 0.2 L/ha dosage produced the best effects,and regarding relative growth rate,the 0.2 L/ha and 0.3 L/ha dosages produced the best results relative to the control.The harvest index did not benefit from the used dosages,while a higher agricultural yield was achieved using the 0.2 L/ha and 0.3 L/ha dosages at 18.03%and 12.88%compared to the control.Therefore,VIUSID agro positively influenced the yield behaviour of pak choi.
