Experiments were conducted over 2 years during the dry season of 2002 (June-September) and wet season of 2002-2003 (December-March) at Regional Research Station, Tamil Nadu Agricultural University, Vridhachalam, India, to study the influence of two colors of polyethylene film mulch (black and white polyethylene film mulch), herbicides (Fluchloralin at 1.0 kg/ha and no herbicide application), and three plant geometries [30 x 10 cm, 20 x 20 cm (two seeds/hill), and 20 x 15 cm] on soil properties, growth, and yield of groundnut.

Control measures

1. The weeds can be controlled either manually or through the use of herbicides/weedicides. One hoeing after about a month would keep the weeds under control and provides aeration to the developing root. Closer planting and cross sowing was also found effective to reduce these weeds. Because wheat is grown on a very large acreage, it is not possible to control the weeds with manual labour
2. Use of herbicides/weedicides

(A) Broad leaf weeds: Bathua, Satyanashi, Krishnneel, Gazari, Piazi etc.
