Cogongrass is a difficult weed to control in small-scale farming systems and often causes significant crop yield reduction. Field experiments were conducted from 1996 to 1999 at three sites located in the forest/savanna transition zone of Nigeria to determine the influence of intercropping cover ...

Field studies were conducted in 2002 and 2003 at Ibadan, Nigeria, to evaluate the effects on weed control in maize of a new formulation of a mixture of atrazine and metolachlor. The treatments were the new formulation of the mixture at doses from 1.0 to 4.0 kg a.i. ha–1 and the old formulation of...

Cogongrass [Imperata cylindrica (L.) Raeusch.] is a major weed in the tropics where land is intensively cultivated and fallow duration is less than 5 yr. Field studies were conducted in 1999 and 2000 in Nigeria to evaluate cogongrass response to combinations of five weed control options. Treatmen...

The cassava value chain development approach was put into use in the last one year to transform the cassava productivity in some selected states of Nigeria by creating linkages between sustainable supply of raw materials and the large scale cassava processors. In this market-led model, farmers ar...

Various factors influencing the adoption of weed control technologies in Abia State were studied. A multi-stage random sampling procedure was used to select 510 cassava farmers in 2006. Results showed that 56.5% of the respondents were females, that are largely (90.2%) in their productive years. ...
