Growth, Yield and Starch Content of Cassava Following Rainfed Lowland Rice in Northeast Thailand

A. Polthanee, C. Janthajam and A. Promkhambut

Abstract:
The objectives of this study were to investigate growth, yield, starch content and economic return of cassava cultivars grown following rice. Five cassava cultivars including Rayong-7, Rayong-11, Rayong-72, Kasetsart-50 and Huaybong-80 were tested in randomized complete block design with 4 replications. The results showed that at 6 months after growing. Rayong-11 gave the highest of leaf area index as well as leaves and stems dry weight. Rayong-7 produced the maximum fresh tuber roots yield, while Rayong-72 gave the highest dry roots yield. The starch content was not significantly affected by cassava cultivars. Kasetsart-50 tended to give the highest starch content. Cassava grown following rice as a bonus crop provided net income over materials cost 1,163-1,810 US dollars ha-1, depending on the cultivar.
