A field trial showed that strawberries do not need large quantities of N and that N applied in spring had the biggest influence on yield. Plants receiving spring N yielded 43.1 t ha‐1compared with 26.0 t ha‐1by plants not receiving spring N. Although N applied in autumn did not influence yield to a marked extent, it caused a shift in production peaks. Plants that had received autumn N produced an early crop, while plants receiving no autumn N showed a delayed production peak. Highest yields were obtained with 36.5 kg N ha‐1in the spring, and 36.5 kg N ha‐1in autumn in split applications. For optimum yields, N should be applied from mid‐winter in small, regular amounts. Although yield was not greatly affected by K applications, it is essential to keep the soil K content at about 40 ppm Bray II extractable K in order to obtain better fruit size.
