Resumen
Descripción
The experimental work was developed in areas of «Los Palacios» Rice Research Station, belonging to the National Institute of Agricultural Sciences, with the objective of studying the influence of a brassinosteroid analogue synthesized in Cuba, commercially known as BIOBRAS 6, on rice yield and other variables. In the experiment six treatments were studied, the variety INCA LP-2 was used. The character number of panicle/m 2 was the component that most influenced yield response. In general, and taking into account the results of the work, the efficiency of BB 6 can be confirmed as stimulant of agricultural yield in rice crop. Results showed that the total dose of 50 mg.ha -1 was the most effective in both sowing seasons, the phases of active tillering and early stage of heading, in winter, and early stage of heading and filled of grain, in spring, being the best responses.
