Abstract

Experiments were conducted at two locations during the 2010/2011 cropping season for early yam production at Owo in the forest-savanna transition zone of southwest Nigeria to study the effect of time [December (D), January (J), February (F) and March (M) and a Control – no mulch (O)] of siam weed (Chromolaena odorata) mulch application on soil physical and chemical properties, growth and tuber yield of white yam. Mulch material in form of siam weed reduced soil temperature, bulk density, days to 50% sprouting and increased soil moisture content, SOM, N, P, K, Ca and Mg, vine length, leaf area and tuber yield of yam compared with the control. Mulch application in December (D) significantly produced higher (p = 0.05) SOM, N, P, K, Ca and Mg, vine length, leaf area and tuber yield of yam compared with mulch application in March (M). Mulch application in December (D) increased tuber yield of yam by 44.4% at site 1 and 47.4% at site 2 compared with the control (O). Similarly mulch application in December increased tuber yield of yam by 26.7% at site 1 and 23.2% at site 2 compared with March (M) application. However, because mulch application in December is statistically similar to January (J) applications in term of tuber yield, therefore either of the two is recommended for yam production
