Effect of Planting Land Forms and Orientation of Stem Cuttings on Yield of Cassava

Abstract

To ascertain whether tillage land forms and orientation of cassava stem cuttings at planting affect yield, a factorial experiment comprising three landforms and three stem orientations were tested in 2010 and 2012 at Wenchi. The land forms were: (i) no till, (ii) mounds and (iii) ridges, while stem orientations comprised: (a) vertical, (b) horizontal and (c) inclined. The nine treatment combinations were replicated four times in a randomized complete block design (RCBD), and the test crop was the variety, Tekbankye. No till yielded a mean of 17.96 tonnes/ha in tuberous roots, while mounds gave 21.21 tonnes/ha and ridges yielded 23.35 tonnes/ha. Vertical cuttings averaged 21.06 tonnes/ha, horizontal ones gave 21.22 tonnes/ha and those inclined yielded 20.25 tonnes/ha.
