With the recent dry weather, where possible, growers should try to ensure they have sufficient water to undertake a targeted, effectively managed irrigation programme to meet the specification of their target market, advises Potato Council technical executive Chris Steel.
“If you can’t irrigate effectively, avoid light fields that are prone to drying out.
“When soils are dry, it’s best to start irrigation when the first plants initiate tubers, to allow time to complete irrigating the field before 50% have initiated.” explains Chris. “A repeat application may be needed within three to four days if ridges remain dry.”
Good irrigation management is vital, he adds. “It should be scheduled, using an accurate, validated system.”
“Whatever you do, do not do half a job – work has shown that ceasing irrigation after two weeks will still allow scab to infect tubers,” Chris warns.
