e0“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”
e1“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”
