การประมาณการขาดธาตุไนโตรเจนของถั่วเหลืองจากสีใบโดยใช้โครงข่ายประสาทเทียม / สุรศักดิ์ ทรัพยากร = Leaf color based approximation of nitrogen deficiency in soybean using neural networks / Surasak Subpayakorn
The nitrogen amount affects the change of the soybean leaf color and the yield amount. This thesis proposes a simulation of neural networks for predicting the needed nitrogen concentration of soybean. Input data are the difference between the unifoliate leaf color in 3 milimolar concentrated nitrogen and the unifoliate leaf color for examine in RGB color system and the age of soybean. Output data are the needed nitrogen concentration. The experimental result can be demonstrated in the color chart for examining the needed nitrogen concentration.
