Productive Response of Brassica rapa L. subsp. chinensis to Application of VIUSID Agro

Abstract

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.

Growth Response of Hydroponic Lactuca sativa L. to Application of Fertilizer Organic VIUSID Agro®

“…The 0.4 mL L -1 concentration had a similar number of leaves (NL) and greater plant lengths (PL) than the control. These results are similar to others who observed a positive impact of VIUSID Agro ® on the aerial morphological characteristics for lettuce (Peña et al, 2017), radish (Raphanus sativus L.) (Peña et al, 2018) and turnip (Brassica rapa L.) (Calzada et al, 2019). Pinto et al (2017), conducting research with two American lettuce varieties with different organic fertilizer doses, determined that the varieties responded differently in the plant length.…”
