SANTO DOMINGO.- The National Council for Agricultural and Forestry Research (Coniaf) and the Dominican Institute for Agricultural and Forestry Research (Idiaf) presented the results of the introduction to the area of three new varieties of cassava for fresh consumption and for production of cassava and starch and the advantages of applying technical recommendations to improve the productivity and competitiveness of the crop.
Both entities made the presentation on a field day at the farm of the producer Elpidio De Beras, in Piedra Blanca, Las Cuchillas Section, El Seibo municipality, where
The yucca researchers Juan Valdez and Ramón Hernández from Idiaf and the engineer José Nova del Coniaf presented the results of the project to the attending producers and motivated them to use the new varieties and carry out an adequate agronomic management of the crop, through good fertilization. , weed management and pest control, to guarantee high crop productivity and obtain quality cassava for fresh consumption and industrialization.
The cassava varieties introduced to El Seibo and shown to the producers were Lima 40 (dual purpose), Valencia Mejorada, Señorita and it was used as a control to compare the variety used by producers in the area, which is Pecho Rojo or Negrita, the latter both in agronomic management given by the producer and in recommended technical management.
The Lima 40 variety obtained a productivity of 53 quintals per task, followed by the Valencia Mejorada variety with 42 quintals per task and the control Negrita or Pecho Rojo control with 15 and 27.5 quintals per task, with producer management and recommended management, respectively.
Also, in the activity, the benefits of the application of production technology for the production of cassava were presented in an interactive way with the producers. The producers were shown that with the control variety, Negrita or Pecho Rojo, which is the one sown in the area by the producers, if the technical recommendations are applied, the productivity increases from 15 quintals per task to 27.5 quintals per task and the cost production is reduced from 5,800 pesos per task to 4,361 pesos per task.
The technical recommendations for agronomic management transferred were the efficient control of weeds or weeds both manually and with the use of chemical products, pest control and fertilization or supply of nutrients to the plant, based on knowing the availability of nutrients in soil and crop requirements to ensure that the crop gets the necessary nutrients to achieve high productivity and root quality.
At the end of the activity, the participants tasted the introduced varieties.
The activity counted with the participation of dozens of cassava producers from El Seibo and with the presence of Dr. Lissette Gómez from the executive board of Coniaf, engineer José Richard Ortiz, researcher and head of dissemination of Idiaf, engineer María Salomé Peña (Magnolia), in charge of the Regional Development Unit of the Ministry of Agriculture and the host of the activity is the engineer Elpidio de Beras, owner of the plot and collaborator of the project.
This activity is part of the project “Update for technological innovation and competitiveness of the agri-food sector in the Dominican Republic”, which is carried out by Coniaf with the support of researchers in roots and tubers from Idiaf and technicians from the Ministry of Agriculture.
