In the Central North Island, specifically around Ohakune, the agricultural sector has experienced disruptions due to a colder growing season. Steph and Bruce Rollison, who cultivate parsnips and Brussels sprouts, report that their crops have been adversely affected by severe frosts, occurring over a span of four days.
The cold weather induced early senescence in the crops, slowing their growth rate without compromising quality. Despite consistent nutrient management, the Brussels sprouts have not achieved their expected size. Bruce Rollison notes a predicted yield reduction of at least 15%, though the quality remains unaffected.
The colder climate, typically beneficial for winter crops like parsnips and Brussels sprouts, has presented challenges this season with late blossoms in spring, cooler ground temperatures, and higher-than-normal rainfall. The lack of sufficient heat units and sunshine has also impacted vegetable vibrancy. However, recent warmer weather may improve Brussels sprouts growth. Adapting to these conditions, the Rollisons are exploring new Brussels sprouts varieties and considering mechanical harvesting options due to labor shortages, particularly among younger workers. Despite these challenges, manual harvesting remains essential for some crops.
