Weed the crop 10-15 days after germination by light hoeing. Carry second weeding around 40-45 days after sowing.
Apply lime @ 4-6 kg/cent at the time of flowering. This should be followed by earthing up operation. Earthing up provides medium for the peg development. It is an important operation in groundnut. Do not disturb the soil after 45 days of sowing.
Application of Sulphur @ 80 gram/cent and Boron @ 16 gram/cent is recommended in deficient areas.
Irrigation at weekly intervals is found to increase growth rate and yield. Irrigation just before harvesting is found to facilitate easy pod recovery.
