Abstract
SUMMARY Irrigation in 1970 at Gleadthorpe E.H.F. increased potato yields and, when given from the time of tuber initiation, controlled common scab on the susceptible cultivars King Edward, Majestic and Record. Pentland Crown had little scab with or without irrigation. It was the driest May and June since 1934 and there was already a soil moisture deficit (S.M.D.) of 1.8 in. (46 mm) at tuber initiation by King Edward and when water was first given. Subsequently irrigation at 0.6 in. (15 mm) or 0.8 in. (20 mm) S.M.D. was more effective than 1.5 in. (38 mm) or 2.25 in. (57 mm) S.M.D. in controlling scab, and more effective at 0.6 in. S.M.D. when maintained for 4 wk than for 2 wk. Irrigation at 0.6 in. S.M.D. for 4 wk increased the weight of premium (Table Grade) potatoes by respectively, 16, 12, 13 and 12 tons/acre (40, 30, 32.6 and 30 t/ha) for King Edward, Majestic, Record and Pentland Crown. Tubers developed slowly in unirrigated plots both in volume and in the rate that eyes separated. King Edwajd produced more tubers per plant than Majestic; irrigation did not increase tuber numbers.
