Summary
The rates of dry matter accumulation (g/plant/wk) and micronutrient (Zn, Cu, Mn, Fe) uptake (μg/plant/wk) were calculated for Starbonnet and Nato rice varieties. Rates of dry matter accumulation were greatest during the reproductive phase of growth. Rates of micronutrient uptake were largest near the particle initiation stage of growth irrespective of the micronutrient considered. The data suggested that maximum rates of micronutrient uptake were due to net increases in uptake as well as increases in dry matter addition. Cumulative uptake of Cu, Mn, and Fe was largest in Nato, while cumulative uptake of Zn was slightly larger in Starbonnet. re]19750915
