A method for generating new varieties of Cannabis plants with modified growth and cannabinoid phytochemical profiles includes subjecting plant parts of one or more Cannabis plants to pectinase digestion to release plant cells, centrifuging the released plant cells to obtain pelleted cells, and providing the pelleted cells on culture media. The pelleted cells are plated on a first culture media, which is a Murashige and Skoog or Gamborg B5 callus culture media.

Described herein are systems and methods for capturing images of a field and performing agricultural data analysis of the images. In one embodiment, a computer system for monitoring field operations includes a database for storing agricultural image data including images of at least one stage of crop development that are captured with at least one of an apparatus and a remote sensor moving through a field. The computer includes at least one processing unit that is coupled to the database. The at least one processing unit is configured to execute instructions to analyze the captured images, to determine relevant images that indicate a change in at least one condition of the crop development, and to generate a localized view map layer for viewing the field at the at least one stage of crop development based on at least the relevant captured images.

Apparatus, systems and methods are provided for crop stand optimization. In some embodiments a field is planted at a first population prescription determined based on a first data set including forecasted weather. A subsequently determined second population prescription is determined based on a second data set determined after planting, and the planted crop is thinned according to the second population prescription. In some embodiments the crop is selectively thinned to remove plants having a plant removal index below a threshold.

A method of pollinating a plant: flying an unmanned aerial vehicle above the plant and generating a thrust that contacts the plant, that produces a sound pressure level of at least 610.sup.5 Pascal at the plant, and that produces a frequency that induces the plant to release pollen.
