Abstract
In a field experiment during kharif 1992 and 1993 in New Delhi, India, groundnuts cv. ICGS 1 were given 1 hand weeding at 15 days after sowing (DAS) or 2 hand weedings, at 15 and 30 DAS or were not weeded. They were given 200 kg gypsum/ha at sowing (S) or flowering (F) or 200 or 400 kg in 2 equal splits at S and F, or 36 kg elemental S/ha at S. Weed dry weight and weed N and P uptake generally decreased with increasing weeding, while groundnut pod yield and N, P, Ca and S uptake increased. Gypsum and S treatments had no effect on weeds. Split application of 200 or 400 kg gypsum/ha significantly increased uptake of N, P, Ca and S by groundnuts
