Abstract Healthy, well‐rooted planting stocks are important for profitable fruit production of strawberry ( Fragaria × ananassa Duch.). Adequate nutrient inputs and crop‐rotation practices among the most measures to insure a successful, rapid development nursery plants. However, relationships between macronutrient use strawberry‐nursery‐plant formation in different rotation environments not well understood. Our objectives were assess plant P : N nutrition under various limited unlimited applied at growth stages examine how plants cope with inputs. The field studies conducted wheat–ryegrass–ryegrass–strawberry (WRRS) system 2008 another corn–ryegrass–ryegrass–strawberry (CRRS) 2009 Nova Scotia, Canada. crop was cv. Strawberry Festival experimental treatments consisted three mother‐stock (MSP) rates (0, 6.6, and13.2 kg ha –1 ) five daughter‐plant (DPP) 13.2, 26.4, 39.6, 52.8 ), representing 0%–125% regional recommendations nursery. arranged blocks split‐plot design each field. results showed that effects interactions MSP DPP significant < 5%) on whole‐plant acquisition productivity.
