RFID-based plant tracking and data management system for a greenhouse

1. A method for tracking the position and status of plants or plant parts in a greenhouse comprising:

pollinating a first individual parent plant with pollen from a second individual parent plant, each of the first individual parent and second individual parent plants having an associated identification;

associating an identification tag with a data record including the identifications of the first individual parent plant and the second individual parent plant;

attaching the identification tag to seeds produced from pollinating the first individual parent plant with the second individual parent plant;

harvesting the seeds from the first individual parent plant;

moving the harvested seeds and the attached identification tag to a harvest area;

detecting the presence of the identification tag in the harvest area with an interrogation system, the interrogation system receiving an identification signal generated by the identification tag in the harvest area, the presence of the identification tag in the harvest area indicating that the attached seeds have been harvested; and

updating the data record to indicate the seeds have been harvested.

2. The method of claim 1 , further comprising the steps of:

providing an expected date of harvest for each data record; and

issuing an alert if the identification tag is detected in the harvest area prior to the expected date of harvest.

3. The method of claim 1 , further comprising the steps of:

providing a last expected date of harvest for each data record; and

issuing an alert if the identification tag has not been detected in the harvest area prior to the last expected date of harvest.

4. The method of claim 1 , wherein the identification tag is an RFID tag.

5. The method of claim 4 , wherein the RFID tag further includes a power source.

6. The method of claim 1 , wherein the identification tag further includes a sensor and the method further comprising the step of measuring an environmental characteristic with the sensor.

7. The method of claim 1 , wherein the detecting step comprises providing an interrogation signal in the harvest area with a transmitter and receiving an identification signal from the identification tag in the harvest area in response to the interrogation signal.

8. The method of claim 1 , further comprising notifying a user that the identification tag is present in the harvest area.

9. The method of claim 1 , wherein the identification tags further includes a computer readable device containing information relating to the identification of the first individual parent plant or a portion of the first individual parent plant and the location of the first individual parent plant or the portion of the first individual parent plant.

10. The method claim 1 , further comprising providing an expected location for the seeds and alerting a user if the seeds are not detected in the expected location.

11. The method of claim 1 , wherein the step of attaching the identification tag to seeds produced from pollinating the first individual parent plant with the second individual parent plant includes the step of receiving the seeds of the first individual parent plant in a bag, the identification tag being fixedly coupled to the bag.

12. The method of claim 11 , wherein the seeds of the first individual parent plant are connected to the first individual parent plant when the seeds of the first individual parent plant are received in the bag.

13. The method of claim 12 , wherein the first individual parent plant is maize and the step of receiving the seeds of the first individual parent plant in the bag includes the step of placing the bag over an ear of the first individual parent plant, the ear including the seeds.

14. The method of claim 13 , further comprising the step of removing the bag containing the ear and the ear from the first individual parent plant.

15. The method of claim 14 , wherein the identification tag is an RFID tag.

16. The method of claim 1 , wherein the identification tag is attached to the seeds produced from pollinating the first individual parent plant with the second individual parent plant prior to the seeds being harvested.

17. The method of claim 1 , wherein the first and second individual parent plants are within a first greenhouse area and the harvest area is within a second greenhouse area.

18. The method of claim 1 , wherein the data record further includes at least one of a date of pollination, a date of harvest, an expected harvest date, a current location, a current status, a plant output quantity, and a plant output quality.

19. The method of claim 1 , wherein the interrogation system is located at an entrance location of the harvest area.

20. The method of claim 19 further comprising the step of determining when the seeds enter the harvest area through the entrance location.

21. The method of claim 1 , wherein the identification tag includes a unique identifier associated with the identification signal.

22. The method of claim 1 , wherein the data record further includes an identification of the seeds.
