Descripción
Two rice varieties (INCA LP-1 and INCA LP-6) obtained in Cuba at the National Institute of Agricultural Sciences (INCA) were evaluated in the Cesar Department, Colombia. The efficiency tests were developed in four experimental sites, Aguachica and Gamarra (Wet Caribbean), and Chiriguaná and Valledupar (Dry Caribbean), under a Randomized Block design with three repetitions, four treatments (varieties) and two Colombian varieties, Oryzica 1 and Oryzica Caribe-8 as checks. The best result was reached by the variety INCA LP-1 with 8.50 t.ha-1 yield. The Cuban varieties INCA LP-1 and INCA LP-6 showed an excellent agronomic behavior in Cesar soils and climate conditions. They were resistant to the main diseases, obtained excellent number of panicles per square meter, a high number of grains per panicle and good agricultural yields, a characteristic that was shown in the two agroclimatic zones studied.
