Bioorganic Nutritional Alternatives in Carrots (Daucus carota var. sativa), under Intensive Gardening

Abstract

Context: One oftoday´s challenges is to provide food to all inhabitants, taking into account the growth of global population, especially into the cities. Accordingly, the urban farming systems are important, as they offer a real solution in face of the people’s demands. Objective: To compare different bioorganic nutritional alternatives and their influence on growth and yield indicators in carrots (Daucus carota var. sativa). Methods: This research was done at Ernesto Che Guevara intensive green garden (UEB No. 2), from the Agricultural Company of Esmeralda municipality, between December 2016 and March 2017, on non-gley plastic dark soil with high fertility. A completely randomized experimental design was applied, with five treatments and three replicas, the indicators evaluated were plant height, root length, and yield. Results: The best agronomic indicators were achieved in the treatments based on fortified liquid humus enriched with boron, calcium, and zinc, which did not differ among them, but were different from the natural liquid humus, and the control. The fortified liquid humus produced the highest yields and the best economic results. Conclusions: A favorable response was observed to bioorganic alternatives in terms of plant growth and yields. The fortified liquid humus had the best economic effect, with a remarkable increase in revenues, compared to the control.
