Field experiments were conducted in summer season of 1990 and 1991 at the Agricultural College and Research Institute, Madurai to study the uptake pattern and yield of groundnut. Application of 4.00 cm water through line source sprinkler significantly increased the nitrogen. phosphorus and potash uptake by groundnut. Among the seeding methods, ridges and furrows method of seeding recorded higher uptake of nutrients. Pre emergence application of fluchloralin followed by hand weeding on 30 days after sowing (DAS) significantly increased the uptake of nutrients. Improvement in the uptake of nutrients resulted in increased yield of groundnut.
