 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Network Modeling for Forecasting Cassava Yield in Khao Hin Sorn Royal Development Study Center Area) ผู้เขียน: ธเนศ มณีกุล, Sophon Tanamai,  ดร.นิพนธ์ ตั้งธรรม, ศาสตราจารย์ , ดร.พีระศักดิ์ ศรีนิเวศน์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractIn this research, the authors aim to find out network modeling for forecasting cassava yield in Khao Hin Sorn Royal Development Study Center based on Principles of Environmental Systems. The research indicates that there are three structures: soil type, fertilizers used and damaging insects, relating to cassava production. When the authors used these three structures constructed network modeling, we found that the low level of cassava yield (1.8-3.5 tons per rai) consists of 13 models, the medium level of cassava yield (3.6-4.9 tons per rai) consists of 12 models and the high level of cassava yield (5.0-7.0 tons per rai) consists of 7 models. The model giving the highest yield of cassava (7 tons per rai) shows the component of sandy clay loam, fertilizer and organic fertilizer used with no damage from the insects |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Structures of the Agriculture Environmental System of Cassava in Khao Hin Sorn Royal Development Study Center Area) ผู้เขียน:ธเนศ มณีกุล, Sophon Tanamai, ดร.นิพนธ์ ตั้งธรรม, ศาสตราจารย์, ดร.พีระศักดิ์ ศรีนิเวศน์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThis research aims to find out the structures of the agriculture environmental system of cassava in Khao Hin Sorn Royal Development Study Center area, one of the important areas of cassava production in eastern based on Principles of Environmental Systems. The research indicates that there are 18 components of the agriculture environmental system of cassava in Khao Hin Sorn Royal Development Study Center area which consisting of 1) natural structure; precipitation, rainy day, hour of sunny, mean temperature, mean high temperature, mean low temperature, soil type, and area; 2) manmade structure; variety, plantation time, cultivation, rowing, spacing, fertilizers used, weeds control, damaging insects, age of harvest and harvesting method. The structures which have relation to the cassava production are soil types, fertilizers used and damaging insects. |
