Increasing yield and reducing risk through early sowing in South Western NSW

This trial addresses issues which may be a barrier to early sowing in the region. In particular; 1. What varieties preform well from early sowing? How do winter and long season spring varieties compare? 2.Can early sown crops be managed to avoid excessive vegetative growth and low harvest index, particularly in dry finish? 3. How do early sown yields compare with traditional mid-May sowing?本试验针对该地区早播可能存在的各类阻碍性问题展开研究，具体涵盖以下3项议题： 1. 哪些品种在早播条件下表现优异？冬性品种与长生育期春性品种的田间表现存在何种差异？ 2. 早播作物能否通过栽培管理规避营养生长过旺与收获指数（Harvest Index）偏低的问题，尤其在后期干旱环境下？ 3. 早播作物的产量与传统5月中旬播种的作物相比表现如何？
