Abstract

The experimental study was carried out in the areas of �??Los Palacios�?� Rice Research Station, which belongs to the National Institute of Agricultural Sciences (INCA), as well as in �??Cubanacán�?�, �??Caribe�?�, and �??Montoto�?� farms from �??Los Palacios�?� Rice Agroindustrial Complex, with the objective of studying the effects of BIOBRAS-16, a commercially known brassinosteroid analog synthesized in Cuba, on rice yield. For this purpose, five treatments were studied using INCA LP-2 variety, and knapsack sprinklings were performed by hand. Concerning land extensions, J-104 commercial variety was used and the applications were carried out by plane. The results showed that panicle number per square meter was the highest influencing component on yield response. Under experimental conditions, the best BIOBRAS-16 response was provided by the treatment in which the application was performed at the beginning of heading and during the grain-filling period, using a total rate of 20 mg.ha-1. There was a positive response of BIOBRAS-16 application to agricultural extensions, regardless the rates and application times used in each of them.
