In Hawke's Bay, the aftermath of Cyclone Gabrielle has left a significant challenge for horticulturalists with a thick layer of silt covering productive land. However, some vegetable crops are showing resilience by pushing through this barrier. Plant and Food Research is now assisting growers in identifying which crops can thrive under these conditions, aiming to sustain their businesses in the process.
Hamish Thomas, NH Packing operations manager, reports that their land in rural Hastings, located between the Ngaruroro and Tūtaekurī rivers, was severely affected when the rivers overflowed. Despite the substantial silt deposit, Thomas sees potential in utilizing the silt positively for future productivity. Plant and Food Research scientist Dr. Eduardo Dias de Oliveira is conducting experiments on the NH Packing land to explore effective strategies for cultivating crops on silt-laden soil.
Initial tests with maize, broccoli, peas, and carrots at various silt depths have shown that maize, with its larger seed size and root system, is particularly promising in the early stages of growth. Broccoli also shows potential, whereas peas and carrots struggle with the silt's coarse texture. This research aims to provide valuable insights for growers navigating the challenges of silt-affected land.
