Agronomic and economic performance of maize (Zea mays L.) as influenced by seed bed configuration and weed control treatments

Poor method of weed control and indiscriminate use of herbicides led to low yields, economic returns, and increasing environmental pollution in the southern Guinea savanna of Nigeria. These prompted the conduct of field trials in the 2018 and 2019 cropping seasons to determine the effects of seed be...
