Sumario: The experiment was carried out at the ExperimentalStation “Alfredo Volio Mata” of the University ofCosta Rica. It is located to an altitude of 1542 m. We evaluatedgrowth and quality of the white corn hybrid 3002 W(Pioneer) recommended for the high elevation areas of theprovince of Cartago, Costa Rica. Dry matter yield per hectare,dry matter content, crude protein, ashes, neutral detergentfiber and its fractions as well as digestible energy were determinedfrom 70 to 154 days of growth. Corn ears started toappear at day 84. Crude protein and digestible energy werehigh until day 84 (>12% CP and >2,8 Mcal DE/kg DM) andbecame lower after day 112 (> 9% CP and >2,3 Mcal DE/kgDM), with less than 15% dry matter which is not recommendedfor ensiling. At 126 days of growth it yielded 17,9 t ofdry matter per hectare with 20% dry matter content, 7,9%crude protein, 2,2 Mcal ED/kg DM, 76% neutral detergent fiberand 4,8% lignin.
