บทคัดย่อ (EN): The investigation was conducted to determine the effects of paclobutrazol and mepiquate chloride on growth, yield and starch content of cassava at different harvesting dates. The experiment was conducted at Land Development Department Experimental Field, Khon Kaen, Thailand in 2009 under rainfed condition. A factorial in randomized complete block design was employed in this study. Factor one was plant growth regulator application included sole application of paclobutrazol (PBZ) or mapiquat chloride (MC), PBZ combining with MC and no application of growth regulator as control. The second factor consisted of four harvesting dates at 8, 9, 10 and 11 months after planting. The results found that sole application of PBZ or MC or PBZ combining with MC application adversely decreased plant height significantly, but significantly increased leaf area index as compared to control across all harvesting dates. Sole application of PBZ produced significantly higher storage root yield than those of sole application MC, but not significant difference with PBZ combining with MC and no application control across all harvesting dates. Cassava harvested for 9 months and 10 months were significantly higher storage root yield than those of harvesting at 8 and 11 months across all growth regulators application. The PBZ and MC application had no significant effect on the starch content in storage root of cassava across all harvesting dates. Cassava harvested for 8 months gave the highest starch content in the present study.
