Identification of an economic alternative to promote production systems using this species is critical to reduce forage production costs, and indirectly feeding cost. The objective of this study was to identify the most economically feasible method for tithonia seed production using either vegetative planting materials or gamic seeds for plant propagation under Cuban conditions. Detailed gamic seeds production costs of tithonia from plots planted using either vegetative planting materials or gamic seeds were estimated. The cost of production per kilo of gamic seeds was US$ 15.07 and 11.04, when multiplication plots were established using either vegetative planting materials or sexual seeds, respectively. The investment for establishing one hectare of a tithonia multiplication plot was reduced to one third when gamic seeds were used, as compared to the use of vegetative planting materials (US$ 142.13 vs. 472.05, respectively).</p> ER -
