dc.description.abstractAn experiment was conducted at the College of Agriculture, Vellayani to study the effect of graded doses of nitrogen and phosphorus on the uptake of nitrogen and phosphorus at three growth stages of sunflower viz 20th day after planting, flowering and harvest. The effect of nitrogen up to 90 kg/ha resulted in significant linear increase in nitrogen uptake at all the stages except on the 20th day after planting. Phosphorus at 90 kg level showed significance in enhanced nitrogen uptake at the 20th day of planting but not later. While for the phosphorus uptake, significant effect was noticed due to increased levels of application of nitrogen at all the three stages, levels of applied phosphorus did not bring about significant changes in the uptake of this nutrient Increase in uptake of these nutrients showed a linear relationship with the magnitude of growth of the plants.en_US
