Yield trial on cassava was conducted at the NOMIARC, Dalwangan, Malaybalay City on 2006-2007 to evaluate promising cassava cultivars for food, feed, starch and, alcohol; to identify high yielding cassava varieties with acceptable dry matter content; and to monitor pest incidence. Sixteen lines/varieties were evaluated for yield, processing. Hydrocyanic (HCN) content and pest resistance. The trial was laid out in Randomized Complete Block Design (RCBD) with four replicates. Results showed that KU50, (check for processing) out yielded all lines tested which exhibited highest total root tubers of 47.50 tons/ha followed by OMR 40-36-21 and Lakan 1 (check for food) with same total root yields of 44.14 tons/ha. Lakan 1 obtained the longest peduncle length of 3.34 centimeters and is identified as the best variety for food with longest HCN content of 1-4. Most of the entries evaluated obtained high DMC ranging from 38 percent to 46 percent of which the highest was obtained by CG-01-02-01 followed by MOP 43-34 and KU 50 with 46%, 44.55% and 44.25%, respectively. Lines/varieties with highest DMC consistently have highest sugar content of 38%, 36.3%, and 36%, respectively. It was also observed that lines/varieties tested were resistant to pests. Moreover, economic analysis showed that KU 50, OMR 40-36-21 and Lakan obtained the highest net returns of PhP 35,670.00/ha, PhP 29,810.00 and PhP 27,710.00. Recommended varieties for food and processing are Lakan 1 and KU 50.
