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.

Abstract: A system for remote monitoring of plants is provided. The system includes (a) at least one sensor positioned on, or in proximity to, a plant, the at least one sensor being for collecting data pertaining to at least one plant related parameter; (b) at least one user client being for receiving and optionally processing the data from the at least one sensor to thereby determine a state of the plant; and (c) a communication network being for communicating the data from the at least one sensor to the at least one user client.

Abstract: A method of assessing a state of a plant is provided. The method includes: (a) collecting data pertaining to at least one plant related parameter over a predetermined time period; and (b) analyzing the data collected over the predetermined time period to thereby identify a trend in the data over at least a portion of the predetermined time period, the trend being indicative of the state of the plant.

Abstract: A system for estimating evapo-transpiration from a plant is provided. The system includes (a) a first detector for detecting environmental radiation at a vicinity of the plant; (b) a second detector for detecting air humidity at a vicinity of the plant; (c) a third detector for detecting air temperature at a vicinity of the plant; (d) a fourth detector for detecting boundary diffusion layer resistance at a vicinity of the plant; and (e) a processor communicating with the first, second third and fourth detectors for retrieving data from the first, second third and fourth detectors and for calculating, based on the data a value corresponding to the evapo-transpiration from the plant.
