Evaluation of Potential Productivity Between Plant Cane and The First Ratoon of 16 Sugarcane Varieties Grown in The Sandy Soil Area in Phitsanulok Province

Abstract

Phitsanulok province has a landscape suitable for sugarcane production. The most of sugarcane production areas of this province set into sandy soil condition. Such this factor leads to comparative study of sugarcane varieties for adaptability to sandy soil condition. Therefore, the objectives of this study to achieve adaptable varieties to sandy soil conditions in Phitsanulok province by comparative study in both plant cane and the first ratoon stages.
The RCBD with 4 replications was set. Fourteen sugarcane varieties from Office of the Cane and Sugar Board, Kasetsart University Kamphaeng Saen Campus and Suphan Buri Field Crops Research Center were propagated and compared with the standard check varieties, KK3 and LK92-11.  Daily rainfall, yield and yield components were recorded in both plant cane and the first ratoon stages. The results showed that the cumulative rainfall in plant cane stage was higher than the first ratoon stage. Such rainfall content lead to yield and yield components of plant cane stage was higher than the first ratoon stage too. Water content in any source lead to cane growth and yields, especially in shooting stage. Thus, UT84-10 and TBy27-0590 were closely high yield to check varieties both in plant cane and the first ratoon stages.
