MIRANDA-CABALLERO, Alexander et al. Quality Assessment of Mechanized Rice Transplantation in Cuba. Rev Cie Téc Agr [online]. 2022, vol.31, n.2  Epub 13-Mayo-2022. ISSN 2071-0054.

Mechanized transplantation of rice is being imposed worldwide and it requires certain conditions to develop the process efficiently like the production of seedlings in trays. In Cuba, transplanting machines with the system to the filling of the trays are being acquired, so it is necessary to establish a technology that allows the transplanting machines to be put into operation. The objective of this research was to evaluate the quality of rice seedlings to be used in mechanized transplantation under sowing conditions, in Pinar del Río Province, Cuba, with the use of the ERP-60 transplanter. Among the main results obtained in the tray seedbed technology at the time of transplantation, an interaction was found between the factors under study. When the component elements of the substrate were mixed and left at rest, the plants found the appropriate conditions for growth, in the four-element substrate (ST + MOT + FCSM + CAC), with 30 or more days of rest. This made possible to achieve seedlings of 15.37 cm high and 2.19 mm thick, 19 days after the seed germinated, complying with the requirements for transplantation with the ERP-60 machine.
