INFLUENCE OF NITROGEN FERTILIZATION AND DIGGING DATE ON STRAWBERRY PLANT MATURITY
Mature nursery strawberry plants might be described as those that show uniform stands and good field performance, when planted inmediately after digging. When immature plants due to an early harvest are used, usually the result is a poor performance throughout the plant life. A National INIA Project was developed using plants from two nurseries located in Castilla-Leon (Spain). Three strawberry genotypes were treated with different nitrogen rates. Commercial daughter plants were sampled from mid-September until the second week of November. Significant differences among cultivars, nitrogen rates and harvest dates were established. Simultaneusly, in central sampling dates, runner plants of each location and treatment were harvested and planted in the strawberry production area (Huelva, south east coast of Spain) to evaluate different variables related to the yield and with quality fruit. Correlations between nursery and fruit experiments were found, showing that this methodology could be used to determine the optimal digging date of strawberry nursery runner plants early in the fall.
