Abstract

Rice production in Cuba is seriously affected, due to the occurrence of red rice (Oryza sativa L.). The damage levels are higher in the state sector, but other ways of production are affected as well. The present work was developed at �??Los Palacios�?� Rice Research Station, belonging to the National Institute of Agricultura Sciences (INCA), during 1999-2001 period, using a randomized block design with four repetitions, where two agroecological practices were carried out, in order to find alternative solutions for the chemical control of this crop species. Annual soybean-rice rotation, after its cultivation, was performed by means of two variants. In the first one, the soil was flooded for 30 days and, later, prepared by mudding. According to the second variant, after soybean cultivation, the soil was also prepared by means of a mudding process. The results of both technologies were compared using the productive practice method, which consists of chemical desinfection. Soybean-rice rotation, as well as soil farming by mudding, using the former two variants, enable to reduce more than 98 % of red rice mixures in two years and improve its physical and chemical conditions. This allows yield increment from 1.5 to more than 5 t.ha-1. The profits obtained by using both agroecological variants surpassed 1500 pesos.ha-1.
