Abstract: CRISTAL, RAQUEL y GATDULA, "Effects of Topping Dates on Tuber Yield of Cassava." B.S. Thesis, Agro-nomy, Don Severino Agricultural College, Indang, Cavite, April 1989. Adviser: MR. CELSO S. CRUCIDO. The study was conducted in a 425 square meter land in Alulod, Indang, Cavite from June 1988 to January 1989 to determine the effects of topping dates on the tuber yield of cassava. Randomized Complete Block Design (RCBD) was used in the study. It was composed of four replications and four treatments. The treatments used were as follows: Treatment 1 (untopped), Treatment 2 (topped at 8 weeks after planting), Treatment 3 (topped at 16 weeks after planting) and Treatment 4 (topped at 24 weeks after planting). Based on the result of this study, plants in Treatment 4 (topped at 24 weeks after planting) produced the highest fresh weight of marketable tubers, number of marketable tubers and the longest tubers. TO highest computed yield and lowest fresh weight of non-market-able tubers per plant was also obtained in Treatment 4 (topped at 24 weeks after planting). The results showed that topping of cassava at 24 weeks after planting had an appropriate balance between top growth and tuber growth; thus, considerable increase in tuber yield. This implies that the source is concentrated more on the tuber after topping.
