| Abstract:
A series of fertilization experiments were carried out in a subtropical environ-ment of northwestern Argentina (province of Tucuman, 27°04’S-65°25’E) to deter-mine optimum range of nitrogen fertilization for strawberries grown in a winter-spring production system. One study was conducted in 1999 on the cultivars ‘Cama-rosa’, ‘Cartuno’, ‘Chandler’, ‘Rosa Linda’, ‘Sweet Charlie’ and ‘Tudla-Milsei’. Two studies were conducted in 2000 on ‘Camarosa’, ‘Sweet Charlie’ and ‘Tudla-Milsei’. A fourth trial was run in 2001 on ‘Camarosa’ and ‘Tudla-Milsei’. Fresh-dug strawberry transplants were used in all the experiments. Cropping beds consisted of drip-irrigated raised beds covered with black polyethylene mulch. Data show that nitrogen fertilization in excess of 155 kg ha-1 is unnecessary. These results have both practical and environmental implications. | |
