Abstract: A method of predicting fruit quality in a crop before harvesting the crop, comprises receiving a fruit quality threshold for the crop, and selecting a sub-seasonal time-window and a growth threshold, based on the fruit quality threshold. The method also comprises monitoring growth of the crop before a beginning of the time-window, and continuing the monitoring throughout the time-window. If the monitored growth is below the growth threshold during at least 80% of the time-window, then the method provides a prediction output that the fruit quality is above the fruit quality threshold for at least a first percentage of the crop.

Abstract: A method of managing treatment of crop is disclosed. The method comprises: monitoring a first parameter describing a daily shrinkage of a plant part of the crop, and a second parameter describing daily growth rate of a plant part of the crop. The method further comprises calculating a plant status function based on a value of the first parameter and a value of the second parameter, and operating a crop treatment system responsively to the plant status function.

Abstract: A method of managing treatment of crop is disclosed. The method comprises: monitoring at least one parameter describing growth and/or condition of a plant and calculating a plant status function based on a value of the at least one parameter. The method further comprises comparing the calculated plant status function to a plant status baseline corresponding to a predicted yield or a predicted yield change, and operating a crop treatment system responsively to the comparison.
