A method of planting field seeds in a test plot field comprising a plurality of plots with a plurality of parallel seed rows wherein a plurality of plots are separated into parallel ranges comprised of a plurality of side by side plots, with the ranges being separated by parallel alleys extending at right angles to the seed rows, comprising, using a multi-row planter capable of simultaneously planting field seeds in a plurality of parallel rows, positioning the planter in a corner of a substantially rectangular field to be planted and heading the planter in a direction to plant a plurality of plots in a longitudinal direction along one side of the field, placing a GPS device on the planter and operatively connecting the same to a computer, predetermining the length of a longitudinal vector comprising the distance between centerlines of two adjacent alleys, providing a trigger mechanism on the planter to deposit field seeds in the soil of the field in the location of each of the rows, and to withhold the deposit of seeds in the alleys, taking a GPS reading on an end point of beginning on the end of a first set of vectors extending along the rows in a first plot, moving the planter longitudinally through the field in the direction of the rows to plant the first tier of plots, continuously gathering GPS data from the GPS device and feeding the same to the computer while the first plot is being planted, and causing the computer to automatically and intermittently cause the planter to plant seed and to stop planting seed as the planter progresses longitudinally through the field as the GPS data advises the computer that the planter has traveled a predetermined distance, with the GPS device providing data to the computer both as to the distance and the direction traveled by the planter, so that seeds will be planted in the rows of the plots of the first tier of plots without planting seeds in the alleys between those plots, and sequentially moving the planter longitudinally through the field to similarly plant additional tiers of plots parallel to the first tier of plots. view more

A method for triggering a seed planter to establish a plurality of field seed test plots, comprising,</claim-text> positioning the seed planter at a corner of the area to be planted, establishing the position of the planter when the planter is ed to start or stop planting seeds, recording the initial position of the planter and establishing the position of the planter when the planter is tripped to start or stop planting seeds, moving the planter across a field that is to be planted, switching the planter on or off to deposit or stop depositing seeds, reversing the direction of the planter such that the planter faces in the direction opposite to the initial path across the field such that the planter is disposed to a return path so that the edge of the first path is contiguous to the edge of the return path, calculating start locations and stop locations for the planter to start or stop planting seeds, moving the planter across the field on the return path, automatically tripping the planter to start planting seeds such that as the planter passes contiguous to an area planted on the previous path the seed planter is switched on, automatically tripping the planter to stop planting seeds such that as the planter passes contiguous to an area where no seeds were planted on the previous path the planter is switched off, and whereby on each consecutive pass across the field a pattern is created of plots with planted seeds and intervening alleys with no seeds. view more

The method in claim 3, wherein the location of said planter is established via a precision location means for precision location operatively associated with the planter.

The method in claim 4, wherein the precision location means utilizes signals is selected from the group consisting of GPS, radio, microwave, sonar, radar and laser.

The method in claim 3, wherein the location of said planter is established via a precision location device operatively associated with the planter.

The method in claim 3, wherein the position of said planter is recorded via a data recording means operatively connected to the precision location means.

The method in claim 3, wherein said planter is tripped to start or stop planting seeds while the planter is moving across the field.

The method of claim 3, wherein the start or stop planting seed locations of the planter are calculated.

The method of claim 3, wherein said planter is tripped to start or stop planting seed for automatically controlling the seed planter operatively connected to the computation means.
