Effect of timing of nitrogen top-dressing on yield and yield components of direct-seeded wetland rice



Effect of timing of nitrogen top-dressing on yield and yield components of direct-seeded wetland rice



Surinaamse Landbouw 35(1-3): 3-13



Rice SML Eloni was given 120 kg N/ha in split dressings at mid-tillering, panicle primordium initiation, panicle differentiation and pollen mother cell differentiation. N at mid-tillering was a prerequisite for high grain yields. A second dressing early in the reproductive period was required for max. spikelet differentiation which was a major determinant of storage capacity and grain yield. Late top dressing only slightly increased grain wt.
