Abstract: There is provided a method comprising: computing state parameter(s) indicative of a state of a target crop at the target field based on output of crop physiological sensor(s), and classifying by a classifier(s), the state parameter(s) and the agricultural practice(s) into instructions for administration of the agricultural practice(s) to the target field, wherein yield and/or quality of the target crop at a future target event is predicted to be increased when the instructions are implemented relative to the yield and/or quality of the target crop that is predicted at the future target event when an alternative administration of the agricultural practice(s) is implemented, wherein the classifier(s) computes the instructions based on previously obtained instructions associated with respective reference fields associated with respective state parameter(s), and yield and/or quality of respective reference crops at respective reference fields at historical reference events corresponding to the future target event
