Abstract: 

There are references of the use of the growth promoter VIUSID agro in crops such as bean (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.) and anthuriums (Anthurium andreanum Lind.) in tropical conditions, however, in horticultural crops such as lettuce (Lactuca sativa L.), Swiss chard (Beta vulgaris var. cicla.), beetroot (Beta vulgaris L.) and radish (Raphanus sativus L.) there is no product use technology. Whereby the aim of this experiment was to evaluate the effect of VIUSID agro on the productive performance of these vegetables in terms of organoponics or urban agriculture. Four experiments were designed where an experimental design of randomized blocks with different doses and a control group were used. Variables related to productive performance of the crops were evaluated. Positive results were achieved, such as the increase of the dry mass of lettuce leaves, compared to control (52.67% vs. 55.87%) and the dry mass of the root roots was over 50%. Yields increased in the most favourable treatments by 30.66% in lettuce, 25.90% in chard and over 50% in beetroot and radish. In the Pearson correlation analyses it was determined that there is a significant linear relationship between the vegetative growth of crops and their final yield or production. VIUSID agro favoured the productive performance of the horticultural crops evaluated; dosages with the best effect were 0.2 L ha-1 in lettuce and 0.7 and 1.0 L ha-1 in the remaining crops.
