“…Reported strawberry N uptake has ranged widely from 59 kg · ha -1 (Albregts and Howard, 1980) to 200 kg · ha -1 (Latet et al, 2002) with differences driven largely by the level of crop productivity. Nitrogen content of fruit averaged 1.2 Mg · kg -1 fresh weight in these seven fields, similar to that found by Tagliavini et al (2004) but substantially higher than reported by Black et al (2005).…”

The impact of strawberry production on nitrate contamination of groundwater is of major concern in the central coast region of California. Nitrogen (N) fertilization and irrigation management practices were monitored in a total of 26 fall-planted annual strawberry (Fragaria ×ananassa Duch.) fields in 2010 and 2011. Soil mineral N (SMN, top 30 cm depth) was determined monthly. Irrigation applied was monitored, and crop evapotranspiration (ETc) was estimated. Growers were surveyed regarding their N fertilization practices. Aboveground biomass N accumulation was estimated by monthly plant sampling in seven fields. The effect of preplant controlled-release fertilizer (CRF) rate on fruit yield was investigated in three fields. The growers’ CRF application rate (121 or 86 kg·ha−1 N as 18N–3.5P–10.8K, 7- to 9-month release rating) was compared with a half rate (all fields) and no CRF in one field. The rate of N release from this CRF product was evaluated using a buried bag technique. Median CRF N and total seasonal N application (CRF + in-season fertigation through drip irrigation) were 101 and 260 kg·ha−1, respectively, with total seasonal N application varying among fields from 141 to 485 kg·ha−1. Biomass N accumulation was slow through March (less than 25 kg·ha−1) and then increased by ≈1.1 kg·ha−1·d−1 from April through mid-September. Mean seasonal biomass N accumulation was estimated at 225 kg·ha−1 by 15 Sept. Approximately 70% of CRF N was released before 1 Apr. Biomass N accumulation between planting and April was much lower than the combined amount of CRF N release and SMN decline over that period, suggesting substantial winter N loss. Conversely, N loss during the summer harvest season (May through August) appeared limited in most fields. Median SMN was maintained below 10 mg·kg−1, and median irrigation was 113% of estimated ETc during this period. Reduction in CRF rate did not affect marketable fruit yield in two of three trials; an 8% yield reduction was observed in the remaining trial when the CRF rate was reduced, but the decline may have been affected by spring irrigation and fertigation practices.

“…These results reveal that the leaf nitrogen content in all treatments was optimal for growth and quality of strawberries and was not affected by irrigation or bio-stimulant application. Fruit nitrogen content at peak harvest provides a sufficiently representative estimate for calculating the nitrogen of the total strawberry crop, as the fresh weight nitrogen content is a function of dry matter content, and therefore fruit quality (Black et al, 2005). The fruit nitrogen concentrations reported here, (0.91% to 1.07%) are similar to values previously reported in winter production systems (0.9 to 1.34%) (Albreghts and Howard, 1978;Black et al, 2005).…”

In the Mediterranean region of Turkey, strawberry production is a vital part of the agricultural sector, providing high rates of employment and farm income. Optimizing water application and effective cultivation practices are of considerable importance in improving strawberry yield. In this study the response of strawberry a cultivar (Fragaria ananassa Duch. cv. Rubygem) to irrigation regimes and bio-stimulant (seaweed extract) use were investigated, by evaluating the yield and morpho-physiological parameters under high tunnel conditions in the Mediterranean environment. The amounts of irrigation water applied were 0.50, 0.75, 1.00 and 1.25 times the water surface evaporation, measured by a standard Class A pan, and the corresponding regimes were denoted as Ir 50 , Ir 75 , Ir 100 , and Ir 125 , respectively. There was a significant decrease in total berry yield and number of berries in the Ir 50 irrigation regime. The maximum total berry yield was attained at Ir 75 in both applications (585.7 g/plant and 521.9 g/plant under bio-stimulant and control applications, respectively). However, the results of Ir 75 , Ir 100 and Ir 125 did not reveal any significant yield benefit. The bio-stimulant application provided a significant, 17% increase, in berry yield. The stomatal conductance and leaf water potential were reduced as irrigation application rates decreased. Conversely, stomatal conductance and leaf water potential were statistically higher, 41 µmol•m-2 •s-1 and 0.5 bar, respectively, after the use of the bio-stimulant, as it alleviated the negative effects of water stress. Bio-stimulant application also significantly increased fruit nitrogen content by approximately 14%. In conclusion, considering the irrigation regimes of strawberries grown under high tunnels in the Mediterranean environment, water use is recommended at around 274 mm (Ir 75), along with bio-stimulant application for optimal yield.

“…Some amount of N in each of the three production systems was taken up by the fruit. Black et al (2005) reported 0.666 mg N/g fruit (fresh weight) for 'Allstar' in the AMR system. Fruit N uptake was not accounted for in this study as a result of the timing of destructive tissue harvest.…”

Additional index words. advanced matted row, Fragaria ·ananassa, erosion, pesticide, plastic mulch, nitrogen uptake, nitrogen use efficiency Abstract. The environmental effects of the three strawberry (Fragaria ·ananassa) coldclimate production systems were compared: the traditional method of conventional matted row (CMR) and the two more recently developed practices of advanced matted row (AMR) and cold-climate plasticulture (CCP). Side-by-side field plots were instrumented with automated flow meters and samplers to measure and collect runoff, which was filtered and analyzed to determine soil, pesticide, and nitrogen losses. Although annual mean runoff volumes were similar for all three production systems, the soil losses from CMR plots were two to three times greater than the CCP plots throughout the study and two to three times greater than the AMR plots only in the first year of the 3-year study. In general, decreases in erosion and runoff volumes were observed in plots that were disturbed less by machine operations and had less foot traffic as a result of decreased need for hand weeding and in the plots that used straw mulch in the furrows between the beds. Timing and intensity of precipitation events also influenced the amount of soil erosion. Pesticide residues and nitrogen losses were also greatest in the runoff from the CMR plots. The two systems that used drip fertigation, AMR and CCP, also had higher nitrogen uptake efficiencies. Overall, the CCP and AMR systems performed similarly for most criteria; however, considering the nonrenewable nature of the plastic mulch and the need to dispose of the plastic mulch in a landfill, the AMR system was more environmentally sustainable than the CCP system.Strawberries presently rank fifth in the United States behind bananas, apples,
