Yields were recorded from a potato crop grown in the first year following a grazing trial comparing four strains of white clover, previously described in this journal (2 & 3). The Kent clover strain, which was the most persistent and which had produced the greatest live‐weight increase per acre, gave the highest yield of potatoes. The Dutch white clover, which had been the poorest in the grassland trial, gave the lowest yield of potatoes. A 2 × 2 × 2 N, P, K fertilizer design was superimposed in the form of split plots. Nitro‐chalk at 5 cwt. per acre and muriate of potash at 2 cwt. per acre both caused significant reductions in yield, and this was thought to be due to the exceptionally high soil fertility status of the field. The fertilizer × clover interactions were non‐significant, and contributed little towards an explanation of the fundamental basis of the soil fertility differences caused by these four clover strains.
