Abstract

A study was conducted to investigate the effects of three varieties of sweet potato (VitAto, Orange and Stone) by three cutting speeds of the mower (2300, 2500 and 2700 rpm) at three different moisture content for the plant (22.4, 30.39 and 41.06 %), wet base (wb %). The results indicate that all the treatments were significant at p ‹ 0.01 significance level for percentage of sweet potato vine pulverized passing through the sieve (< 28 mm). The best result was by the Stone type of sweet potato at 22.4 % moisture content of the plant and 2300 rpm speed of the mower with 89.16 % of the pulverized vine. Data were analyzed statistically using ANOVA and the least significant difference LSD calculated at 1 % to estimate the differences between the averages.
