Okawa Station is a 1000 ha property owned by Tom Lowry and located on the Napier-Taihape Road, 10 km northwest of Hastings. The property is summer dry with a rainfall of 750 mm and light silt loam soils. Arrowleaf clover has been grown as a annual crop for feeding lactating ewes and early weaned lambs for the past 3 years. In 2013, a total of 60 ha of Arrowleaf clover was established as pure species and mixes to provide greater spring flexibility. A 10 ha trial paddock is being used to examine differing methods of establishing Arrowleaf and Persian clover. Measurements will include dry matter production, seed yield and hard seededness. Further details and results are available in the Hub notes.
