Effect of Hill Density, Seedling Number/Hill, and Potassium on Late-Transplanted Sali (Rainfed Lowland Winter) Rice Yield in Assam, India

Abstract

Late planting of Sali (rainfed lowland winter) rice is common among many parts of the Barak Valley zone (Cacher, Karimganj, and Hailankandi districts) of Assam, India because of flooding during July and August, the normal planting time. Yields are usually low under late planting because of poor tillering and reduced panicle size, resulting from progressive drought and low soil K status. Managing the optimum plant population and K status seems to be imperative for stabilizing yield under those conditions.
