Yield of 12 commercial hybrid carrot (Daucus carota L.) in the field and the packing facilities. Twelve commercial hybrids of carrot (Daucus carota L.) were evaluated in Cot, Oreamuno, Cartago, Costa Rica, with the goal of evaluating yield in the field and in the packing facilities, from June to October 2007. The hybrids evaluated were Bangor F1, Big Sur, Bolero F1, Concerto F1 (VAC 03 F1), XCR3688, Esperanza, Nandrin F1, Napoli F1, S-505, Spearhead, Trinity and Sirkana. Evaluations of the number and weight of total, commercial, first and second quality grade and rejected roots were conducted in the field and in the packing facilities. The materials with higher yield both in the field and in the packaging plant were Bangor F1, Esperanza, Concerto F1, Nandrin F1 and Sirkana. The materials with lowest rejection in the field were Nandrin F1, Sirkana and Bangor F1, and Big Sur, Sirkana, Napoli F1, Bolero F1 y XCR3688, in the packing facility. The most important causes of carrot in the field and in the packaging facilities were forked, cracked, jumbo and small roots.
