In 1945, every farm grew potatoes and Irish migrant workers were still being employed to gather the crop. The varieties grown at that time were Majestic and King Edward. From the 1960s Majestic, Redskin, Epicure and Maris Piper were the main varieties.
New factory markets for potatoes came into existence in the 1950s. The first was for crisps and, in the 1960s, chips. Suitable varieties were Maris Bard, Nadine and Lady Rosetta. Potatoes grown for the crisp manufacturers usually went to Golden Wonder at Bathgate. The 1960s also saw the introduction of artificial irrigation systems. Water was obtained from watercourses directly or via reservoirs, boreholes and wells, using various types of pumps and sprinkler systems. From the 1960s, some farmers co-operated with a commercial potato growing/buying organisation, guaranteeing a market for the crops; from the 1980s most let the ground allocated for potatoes to these organisations, which provided all the workers and equipment. Maincrop potato yields increased during the last 50 years, from 20/25 tonnes per hectare in 1950 to 40/50 tonnes per hectare by 2000.
