During the seasons under investigations (Kharif and summer), the amount of nutrients increased upto 45 days after sowing and thereafter declined as the crop advanced in age. The amount of calcium, however, appeared to increase upto 60 days of crop growth and thereafter declined at harvesting stage. The leaf was the richest in the total amount of nutrients upto the pod development stage, whereafter, the nutrients, especially, nitrogen accumulated more in the developing pods. The amount of nitrogen in the pedicel was more than stem, root and flower during both the seasons. Accumulation of phosphorus, during both the seasons; followed a sigmoid pattern in the leaf, stem and root, whereas in the pedicel and pod, the trend was found to be linear. Potassium accumulated more in the stem as compared to the other plant parts during both the seasons. Nutrient accumulation was influenced by higher dry matter production and better root growth in kharif crop, whereas in summer it was at the expense of energy.
