Extract

1. An account is given of Marsh Spot in the seeds of the green pea (Pisum sativum L.); its economic importance and its effect on the plant, including the germination of the seed, are discussed.

2. Hypotheses advanced by seedsmen and growers to account for the presence of Marsh Spot are discussed.

3. The soils of 165 fields upon which green peas were grown under contract for seed in east Kent during 1933 and 1934, were surveyed in detail and are classified under the American system. A brief description of each is given.

4. The occurrence of Marsh Spot is correlated with the presence of a water table in the soil. A high percentage of Marsh Spot was encountered only in crops grown on fields with a water table within 52 in. of the surface. Thus, in the presence of a water table, the intensity of Marsh Spot reached a maximum of 100 per cent. of the seeds of a sample affected, whereas in the absence of a water table the maximum was only 3 per cent.
