Abstract: A method of estimating amount of carbon fixation in a plant comprises receiving a set of temporal sequences, respectively corresponding to a set of consecutive days, each sequence describing a size of a part of the plant as measured repeatedly over one of the days. Morphologically equivalent pairs of sequences are identified in the set of sequences, and parameter subtraction is applied between parameters representing sequences in each pair of at least a portion of the pairs, to provide a size change of the plant part for the pair. The method estimates the amount of carbon fixation in the plant based on the size change.

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.
