“…This suggests that the unfertilized strawberry plants took up more of the available N from the soil pool, especially in Spring 2001. A replacement of the N that could have come from soil sources with N from a fertilizer application is in agreement with observations of Blatt et al (1981), that no fertilizer N is necessary on high N soils.…”

“…The FN rates we evaluated, either as a broadcast granular or foliar application had no impact on the N concentration of plant parts throughout the season. The leaf percent N we observed during bloom (1.62) was similar to that reported by Blatt et al (1981) and the N concentration in the leaves after renovation for all treatments fell within recommended levels (Hart et al, 2000).…”

“…Responses to FN applied in the fruiting season have been variable with higher FN rates increasing yield in some studies (Albregts and Howard, 1973;Cutcliffe and Blatt, 1984;Latet et al, 2002), positive yield responses to FN in only some years of a multiyear study (Albregts and Sutton, 1971;Karp et al, 2002;Kirsch, 1959;Ullrich and Martin, 1987), to no effect of FN on yield compared to an unfertilized treatment (Blatt, 1981;Breen, 1979;Rodgers et al, 1985). In some studies, high rates of FN have decreased yield or quality (Albregts and Howard, 1973;Darrow and Waldo, 1932).…”

Fertilizer nitrogen (FN) recovery, and changes in nitrogen (N) and dry weight partitioning were studied over three fruiting seasons in June-bearing strawberry (Fragaria ×ananassa Duch. `Totem') grown in a matted row system. Fertilizer nitrogen treatments were initiated in 1999, the year after planting. The standard ammonium nitrate N application at renovation (55 kg·ha-1 of N) was compared to treatments where additional N was applied. Supplemental treatments included both ground-applied granular ammonium nitrate (28 kg·ha-1 of N) applied early in the season and foliar urea [5% (weight/volume); 16 kg·ha-1 of N] applied early in the season and after renovation. When labeled N was applied (eight of nine treatments) it was applied only once. The impact of no FN from the second through the third fruiting season was also evaluated. Fertilizer nitrogen treatment had no impact on total plant dry weight, total plant N, yield or fruit quality from the first through the third fruiting seasons. Net dry matter accumulation in the first fruiting season was 2 t·ha-1 not including the 4 t·ha-1 of dry matter removed when leaves were mowed during the renovation process. Seasonal plant dry weight and N accumulation decreased as the planting aged. Net nitrogen accumulation was estimated at 40 kg·ha-1 from spring growth to dormancy in the first fruiting season (including 30 kg·ha-1 in harvested fruit, but not including the 52 kg·ha-1 of N lost at renovation). Recovery of fertilizer N ranged from 42% to 63% for the broadcast granular applications and 15% to 52% for the foliar FN applications, depending on rate and timing. Fertilizer N from spring applications (granular or foliar) was predominantly partitioned to leaves and reproductive tissues. A large portion of the spring applied FN was lost when plants were mowed at renovation. Maximum fertilizer use efficiency was 42% for a granular 55 kg·ha-1 application at renovation, but declined to 42% just before plant growth the following spring, likely a result of FN loss in leaves that senesced. In June, ≈30% of the N in strawberry plants was derived from FN that was applied at renovation the previous season, depending on year. This stored FN was reallocated to reproductive tissues (22% to 35%) and leaves (43% to 53%), depending on year. Applying fertilizer after renovation increased the amount of remobilized N to new growth the following spring. The following June, 15% of plant nitrogen was derived from fertilizer applied at renovation 2 years prior.

The effects of two nitrogen sources and a row cover were studied for 2 day-neutral strawberry cultivars covered with different row covers and grown for 3 yr at two sites at Lavaltrie and L’Acadie. The nitrogen sources did not significantly (P ≤ 0.05) affect yield and fruit size at either site. However, the black polyethylene mulch combined with cultivar Tribute increased yield and fruit size at both sites. The use of a row cover in the fall did not prevent early frosts or lengthen the picking season. Despite a smaller fruit size and 5–8 d of earliness, good total yields appear possible from a second year crop of day-neutrals. Key words: Strawberry, nitrogen, NH4, sulphur-coated urea, mulching, yield, fruit size.
