Research Abstract

In order to develop a methodology to control citrus alternate bearing, observer measurements of the targeted dynamics were conducted and OGY based control method was established with employing ensemble reconstruction of the dynamics from very short but ensemble data set. The algorism was implemented on a conventional PC. The observer was also detected with hyperspectral imaging technique and Molan'sI and GStatics were identified as a measure of mechanistic process. Not only with the obtained number of fruits, the estimated yield of citrus by remote sensed data set was successfully used to forecasting the yield in individual level
