Sod-seeding of rice in New South Wales

Abstract

In a series of five experiments in the irrigation areas of N.S.W., currently grown rice varieties were sod-seeded and compared under several rates of seeding and levels of applied nitrogen. There were no differences between varieties in their adaptability to the sod-seeding practice. Seedling survival was poor but higher seeding rates increased yields in only one of the four trials where they were tested. Responses to nitrogen fertilizer at seeding were small in the two experiments where it was included, but in one, 80 lb N per acre increased yield from 10,872 lb/acre to 12,292 lb/acre (P<0.05).
