 In: Fertilizer Research v. 1, no. 2, p. 87-9381-663167Summary: Field trials were carried out on Apomu soil (Psammentic usthorthent) and Egbeda soil (Oxic paleustalf) in Southern Nigeria to investigate the effects of fertilizer and weeding on growth and yield of maize (Zea mays L.) under no-tillage and tilled land preparations. On the newly cleared Apomu soil, broadleaved weeds comprised the major portion of the weed flora, with the shrubs being more important under no-tillage. More grasses and sedges were present when the soil was tilled. Regardless of tillage method, there was a >38 per cent yield reduction due to weeds in the unfertilized plots, with yield in tilled plots being almost double
