Yam was intercropped with maize, okra, and sweet potato and subjected to various periods of weed interference and weed-free regimes. The field trials were conducted for two cropping seasons at the research farm of the National Root Crops Institute, Umudike, Nigeria, 5° 29' N latitude and 7° 32' E...

Alley cropping with Leucaena leucocephala (Lam.) de Wit, caused a shift in weed flora away from fast-growing annual weeds that are characteristic of frequently cultivated fields to shade-tolerant, less-competitive weeds. Alley cropping caused a greater decline in weed density over lime than was o...

Live mulch is a crop production technique in which a food crop is planted directly in a living cover of an established cover crop without tillage or destruction of the fallow vegetation. The effect of several established legume covers on weed competition, fertilizer requirement and yield of maize...

The effects of tropical weeds on the yield of while yam were studied outdoors in wooden boxes. When the foliage and roots of weeds were in physical contact with the crop until harvest (full interference), tuber yield of yam was reduced by 76–79% of that obtained under weed‐free conditions over 3 ...

Field studies were conducted in 1991 and 1992 on a sandy loam soil in the derived savanna zone of south-western Nigeria to assess the effect of the underground organs of Imperata cylindrica (L.) Raeuschel on maize grain yield. Total dry matter of I. cylindrica in abandoned arable land averaged 16...
