 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Constraint Factors and Mathematical Models for Forecasting Rice Production in Thailand) ผู้เขียน: ดร.สุดสายสิน แก้วเรือง, รองศาสตราจารย์ ,  Akira Goto สื่อสิ่งพิมพ์:pdf AbstractThe constraint factors in rice cultivation were analyzed with the producing variables such as planted area, quantity of product and actual farm yield. Constraint factors of water resources development, fertilizer usage, the previous season farm price, annual rainfall and the replacement of high yielding rice varieties were closely related to such variables. The mathematical models of the above variables were established respect to relationship of these factors. |
