This “indigo band” does not have to include indigo or blue or any particular “color” and does not have to include wavelengths in the preferred range of—wavelengths of 420-450 nm that are commonly assigned to indigo or near indigo as human perceptions. The addition of light for any reason, including for a trademark or appearance effect, e.g., aquamarine, shall not affect this definition. An Indigo Region Illumination Distribution IRID can include monochromatic, multi-chromatic frequency/wavelength lines or bands, continuous or non-continuous distributions, and distributions that comprise one of more emission lines, or distributions that are absent the general wavelength or frequency for which it is named, i.e., a distribution that is absent wavelengths generally given for indigo, that is, absent approximately 420-450 nm.

An IRID emitter and a MWIR emitter can be combined into one body or component, or device.
[0107] Medium Wavelength Infrared—MWIR—has been variously defined by different international organizational bodies, sometimes using different terms. For example In the CIE division scheme (International Commission on Illumination), CIE recommended the division of infrared radiation into the following three bands using letter abbreviations: IR-A, from 700 nm-1400 nm (0.7 μm-1.4 μm); IR-B, from 1400 nm-3000 nm (1.4 μm-3 μm); and IR-C from 3000 nm-1 mm (3 μm-1000 μm). ISO (International Organization for Standardization) established a standard, ISO20473 that defines the term mid-IR to mean radiation with wavelengths from 3-50 microns. In common literature infrared generally has been divided into near infrared (0.7 to 1.4 microns IRA, IR-A DIN), short wavelength infrared (SWIR or 1.4-3.0 microns IR-B DIN), mid-wavelength (or medium wavelength) infrared at 3-8 microns (MWIR or mid IR 3-8 microns IR-C DIN) to long wavelength infrared (LWIR, IR-C DIN) 8-15 microns to far infrared 15-1000 microns. In this disclosure, throughout the specification, drawings and in the appended claims, MWIR in particular shall have a meaning assigned, and the wavelengths for MWIR shall span from 2-20 microns, and with preferred embodiments in a range of 2-8 microns and sometimes more preferably in a range of 2-5 microns. Source emissions can include emissions from an MWIR emitter E that is formed from materials with known emissivity functions useful in service of the invention, such as known borosilicate glass.
[0108] MWIR Emitter (E)—shall denote any glass or material body that has the requisite optical properties or electromagnetic emissivity properties that allow service to the instant invention as described in the appended claims.

An IRID emitter and a MWIR emitter can be combined into one body or component.
[0109] Motion/in motion—shall include all generally moving states of a harvest, including [1] continuous motion; [2] stepwise motion that can include pauses, starts and stops, or even has reversals—in any combination; and motion induced by vibratory elements or supports that cause a harvest to generally progress, but not always progress, in space
[0110] Planter/Planter Process—shall denote any implement, machine or process which performs or helps perform the act of storing seeds, or depositing or sowing seeds, such as in rows throughout an agricultural field. A planter shall include all components used, such any storage bin, hopper, seed distribution tower, transfer hoses and mechanisms, accumulators, metering components, and deposition components for sowing into soil. A planter shall also include any seed drill or lister.
[0111] Powder coat—shall include any and all coverings, coatings, surface treatments, appliques, and depositions to a surface, including using materials as disclosed, such as borosilicate glass, Pyrex® Glass Code 7740, soda lime glass, aluminum oxide ceramic.
[0112] Process/method—such as referred to in the instant disclosure and appended claims, including referring to a processing theater, can be a process as taught herein that is continuous in time, or non-continuous, including piecewise, piecemeal, stepped, interrupted or delayed application of the methods of the instant invention, and shall also refer to any process for which at least portion of which occurs in real time.
[0113] Processing theater—shall comprise any physical area, surface or land surface, belt, auger, conveyor, panel, web, screen, mesh, volume or space which facilitates, provides for, or allows illumination according to the instant invention and as described in the specification and appended claims, including any wind tunneling region, auger passage, sorting area, staging area, table, accumulator or harvest flow manifold used for processing of a harvest. In this sense, a processing theater can, but does not have to, include a mechanical or physical belt. It can instead comprise an transport area, region, structure, or material body where sorting, collecting, threshing, reaping, parking, consolidating, separating, resting, or landing of a harvest or processing product treatable by the instant invention occurs. The processing theater can also be situated upon, or proximate to, any field as defined in this disclosure.
[0114] Seed—shall include all known seeds, such as outcrossed, inbred, or hybrid seeds; and any embryonic plants, or encased plant embryos; agricultural products; and any other biological material susceptible to, or treatable using the instant invention in the manner disclosed in the specification and appended claims.
[0115] Seed accumulator—shall include any belt, structure, material body or space that can serve to mechanically retain, support, or transport seeds, that forms a processing theater as defined in this section and throughout this disclosure illustratively. Seeds can be in motion across, upon or through a seed accumulator and can be retained by same in continuous, intermittent, paused or varied motion. It is contemplated that an air pressure differential or an air flow can help seeds be retained or supported by, and later expelled by, a seed accumulator.

For example, a wavelength distribution according to the claimed invention can comprise primarily only Medium Wavelength Infrared (MWIR) of wavelengths 2-8 microns, and Indigo Region Illumination Distribution (IRID) of wavelengths 350-500 nm.
DETAILED DESCRIPTION
[0117] Referring now to
[0118] Referring now to
[0119] This disclosure relates to seeds of all types, among them monocotyledons and dicotyledons. Monocotyledons (associated with one seed leaf, not shown) and dicotyledons (associated with two seed leaves, shown attached to the radicle) differ in early seedling development. In monocotyledons, a primary root is protected by a coating, a coleorhiza, which ejects itself to yield to allow seedling leaves to appear, which are in turn protected by another coating, a coleoptile. With dicotyledons a primary root radicle grows, anchoring the seedling to the ground, and further growth of leaves occurs. Either way, germination is marked by the growth and development of the radicle, and allowing the full development of a healthy plant.

[0123] Described very briefly and qualitatively, the method comprises programming said seed using said rapid pulse by delivering to the seed illumination of electromagnetic radiation of a wavelength ranging from 300 nm to 20 microns, and with the illumination so formed and arrayed and timed to deposit only a narrow specific preferred range of between ½ and 3 Joules/cm.sup.2 cumulative energy, but with a minimum average irradiance of 0.2 W/cm.sup.2. The maximum cumulative energy can be higher, depending on species, although the 3 Joules/cm.sup.2 is nearly universal. Though it is just a theory and is not meant to be limiting to this specification and appended claims, this appears to specifically engage and cause an irradiance-sensitive and energy-sensitive innate stimulative exposure response in the seed. The illumination is preferably tailored to avoid deposition of higher than 3 Joules/cm.sup.2 so as to avoid causing a different innate destructive exposure response, reduced germination viability, in the seed at higher deposited energy. So the illumination of the method is not sufficient to induce a change of state of the seed to having reduced germination viability; and nor is it sufficient to cause substantial high temperature burn of the seed.
[0124] As will be discussed below, one preferred illumination embodiment calls for an Indigo Region Illumination Distribution containing substantially wavelengths ranging from 300 to 550 nm, preferably 400 to 500 nm; and also Medium Wavelength Infrared radiation substantially composed of 2 to 20 micron wavelength radiation, preferably 2 to 8 microns. Preferred minimum average irradiance to engage the irradiance-sensitive and energy-sensitive innate stimulative exposure response in the seed can be 0.3 W/cm.sup.2, 0.4 W/cm.sup.2, 0.5 W/cm.sup.2, 0.6 W/cm.sup.2, 0.7 W/cm.sup.2, 0.8 W/cm.sup.2, 0.9 W/cm.sup.2, 1.0 W/cm.sup.2, 2.0 W/cm.sup.2, 3.0 W/cm.sup.2, 4.0 W/cm.sup.2, 5.0 W/cm.sup.2, or 6.0 W/cm.sup.2. The narrow specific range of cumulative illumination energy can be one of: ½ Joule/cm.sup.2 to 4 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 5 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 6 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 7 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 8 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 9 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 10 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 11 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 12 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 13 Joules/cm.sup.2; ½ Joule/cm.sup.2 to 14 Joules/cm.sup.2; and % Joule/cm.sup.2 to 15 Joules/cm.sup.2.

[0133] This is an auger-based conveyance system that can be used to pass seeds to deliver the high intensity short-term exposure of electromagnetic radiation required by the method of the instant invention. Although the electromagnetic radiation wavelength can range from 300 nm to 20 microns for the method, this is a preferred embodiment using Medium Wavelength Infrared and an Indigo Region Illumination Distribution. This AUGER FED TUBULAR EXPOSURE UNIT is a preferred embodiment which has demonstrated meaningful increases in crop seed germination rates, crop seed germination speed, and root mass after germination.

[0135] The auger and auger housing are a total of 5 feet in length, while the heated section of the auger housing is 3 feet. To generate Medium Wavelength Infrared, there is a known emissive coating on the inside of the auger housing (not explicitly shown, indicated by MWIR emitter E). When heated to a target temperature of 350° F. it generates Medium Wavelength Infrared radiation. The emissive coating can be known thermally sprayed borosilicate glass at a thickness necessary to provide/full coverage of the inside of the auger housing. The emissive coating (POWDER COAT of

Tests on Dent Corn Seeds
[0138] Tests were run on dent corn seed, to expose seeds to Medium Wavelength Infrared and an Indigo Region Illumination Distribution for the above cited irradiances and times, up to five separate runs each, with exposure time totals of about 2.1 seconds each run. The seeds were then germinated in soil in a greenhouse environment. Tracking the timing and quantify of seeds that germinated, it was found that dent corn that was run through the system 2 times or 3 times had substantially higher germination rates than a control with no irradiances. There also was found an increase in root biomass, as 1 or 3 runs through the system resulted in large increases in root biomass, from 12 grams (control) to 16 grams. Observed germination rates went from 74 percent in the no-radiation control group up to 92-94 percent for 1.6 and 2.4 Joules/cm.sup.2.
Tests on Rye Seeds
[0139] Tests were run on rye seed, using 0, 1, 2, 3 or 4 runs. The rye seeds were then planted in soil in trays at high density. Visually, it was clear that rye seeds ran through the auger fed tubular exposure unit one time generated a substantially more vigorous stand (denser seedlings with larger above ground biomass in total and per seedling) than the no-radiation control. This indicates efficacy of the method taught and claimed in the instant invention for 0.87 Joules/cm.sup.2.
Tests on Soybeans
[0140] Tests run 1 or 2 times (0.87 Joules/cm.sup.2 and 1.74 Joules/cm.sup.2) using 50 lb bags of seed for each case. Using a 16 row planter and planting during a normal planting schedule, filled two selected rows treated seeds, while filling the rest of the field no radiation control seeds. Early germination was detected, by counting periodically the number of germinated seedlings on random 1 meter lengths of control (non-treated) rows and treated (irradiated) rows. Seeds treated using the instant invention resulted in germination that was two days earlier, thereby establishing the stand approximately 2 days earlier.
Tests on Glycine Max (Soybeans)
[0141] Tests run using the Auger Fed Tubular Exposure Unit, illuminating with Medium Wavelength Infrared MWIR at 0.4 Watts/cm.sup.2 for two seconds, and Indigo Region Illumination Distribution IRID at 0.07 Watts/cm.sup.2 for ¼ second resulted in a 62% germination rate, compared to a 24% germination for an untreated control group. Similar tests on twenty-two 50 lb bags of Wensink™ 2.9 early mid-season soybeans yielded an average V stage (emergence) count of 3.87 for treated plants versus 3.25 for control (untreated) plants.

The second distribution s2 shows another possible distribution from 400 to 550 nn, not continuous and absent UV-A radiation. A third distribution s3 shows various spectral lines of output, with the highest energy radiation at about 480 nm, and consisting of only six emission lines as shown. This can arise from various light sources, such as lasers, and especially ion discharge lamps with no intervening phosphor, etc. A fourth distribution s4 is continuous in part like distribution s1, but is absent mid-wavelengths, and notably is absent wavelengths associated with indigo, for which the Indigo Region Illumination Distribution IRID is named. All these, and other similar distributions are possible as preferred embodiments in service of the instant invention.
[0148] Appearance of the Indigo Region Illumination Distribution IRID to the human eye shall not be indicative of suitability, A Indigo Region Illumination Distribution may not appear “blue” or ‘indigo” to the human eye because of the effect of constituent wavelength components—and response of the human eye to light distributions, including known effects of metamerism, shall not limit or narrow the scope of the appended claims, nor narrow the instant teachings. In the protocol taught and claimed in the instant disclosure, the preferred range of wavelengths for the Indigo Region Illumination Distribution is 400-500 nm, with a distribution centered at about 430-450 nm.
[0149] Known commercially available high output “blue” LEDs (light emitting diodes) can be used to provide necessary light for Indigo Region Illumination Distribution IRID, providing light generally in a wavelength range from 400 to 550 nm. For example, known SiC (silicon carbide) based LEDs with output from 430-505 nm (appearance blue) are available and have a Forward Voltage of 3.6 volts; GaN (Gallium Nitride) and InGaN (Indium Gallium Nitride) based diodes are also available. Mixture of GaN with In (InGaN) or Al (AlGaN) with a band gap dependent on alloy ratios allows manufacture of light-emitting diodes (LEDs) with varied output peaks. Some LED devices using Aluminium Gallium Nitride (AlGaN) produce ultraviolet (UV-A) light also suitable for a Indigo Region Illumination Distribution, and known phosphors can be used to extend spectral range or to serve another objective such as making a trademark color splash without departing from the scope of the invention and appended claims.
[0150] To construct a Indigo Region Illumination Distribution IRID source, commercially available high power UV/violet LED chips are thus available in varied peak distribution wavelengths such as 365 nm, 370 nm, 375 nm, 385 nm, 390 nm 395 nm, 400 nm, 405 nm, and 425 nm with input power ranging from 3 to 100 watts, such as available from Shenzhen Chanzon Technology Co., Ltd., ShenZhen, Guangdong, China. The embodiments shown in Figures which follow employ a 100 watt array, 450 nm peak output. Larger arrays can be built up from constituent chips to serve the requirements of the instant invention for larger scale applications.

[0152] MWIR emitter E is heated using a heater assisted by a heating ring Hr as shown, in thermal communication with illustrative glass (e.g., borosilicate glass) of MWIR emitter E. Borosilicate glass and other similar materials conduct heat across themselves, and this heated glass allows efficient coupling into MWIR wavelengths and allows a pass-through of Indigo Region Illumination Distribution IRID light as shown.

[0157] L1 depicts a spectral density for a clear halogen lamp with a pyrex outer jacket, operating temperature 2400K, with a peak output wavelength of 1.3 microns. This lamp is preferred to obtain high radiation output because of its high operating temperature, and the output can be used to excite borosilicate glass in proximity, as known by those of ordinary skill in the art of lamp design and heat sources.

This lamp is preferred when using as a direct light source to practice the instant invention, because the substantial share of the radiation output is at the preferred range of 2-8 microns.

If desired, underlying heated substrate E′ can itself be a MWIR emitter E as well. In addition, MWIR emitter E+ can be externally optically energized from a distance—or heated with an external lamp or source (not shown) as those of ordinary skill in the art can appreciate.

[0168] A prime mover for agriculture around the world for harvesting a cash crop is the harvester combine, or “combine,” for short. It is so named because it typically performs three functions: [0169] [1] reaping the crop (gathering and cutting); [2] threshing the grain, to remove it from the plant that is harvested; and [3] separating the grain from chaff, tailings, and confounding materials, including cleaning and materials handling. Combines are complex, expensive and have helped produce an economic and agricultural boon around the world. Manufacturers include John Deere, Case International Harvester, New Holland, Massey Ferguson, Claas, and others.
[0170] In older combine harvester designs, a turning cylinder threshes the crop, then reciprocating straw walkers takes grain from the crop. In newer designs that are more prevalent today, a specialized rotor or twin rotors both thresh and separate the grain from the plant. In hybrid designs, a cylinder threshes the grain, then the grain is passed to two specialized rotors that separate the grain from the plant. The grain is typically loaded using augers or other transport into a tank at the top of the combine, or off-loaded.
[0171] Specifically, a unit called a header (cutting platform) divides, gathers and cuts the crop and the harvest is augured or transported to the threshing unit. The threshing unit separates the grain or cash crop from the ears, husks, stems, and straw, and the separator separates grain from chaff, which itself can contain weed seeds. In threshing, impact, rubbing action, and centrifugal forces are used to urge grains or beans from the MOG (material other than grain). Tangential threshing cylinders or units with raspbars, or rotary separation are used, with axial or tangential harvest paths.

In addition, auger or flighting A9 can be fabricated from, or comprise, borosilicate glass, Pyrex® Glass Code 7740, soda lime glass, or aluminum oxide ceramic, and can also comprise a powder coat. This would allow heating the auger or flighting A9 to provide further Medium Wavelength Infrared radiation emissions as taught and claimed here.

The MWIR emitter E in radiant seed accumulator belt 3ZE can be composed using known techniques to comprise a powder coat, and that powder coat can, like the MWIR emitter E itself, comprise a glass selected from borosilicate glass, Pyrex® Glass Code 7740, and soda lime glass, or alternatively aluminum oxide ceramic.

Because of its chance nature, the statistical attribute associated with trying to get two sided illumination on seeds to increase effectiveness is improved using a continuously glowing belt. This can be supplemented with other direct sources MWIR emitters E and IRID emitters 88, and with reflectors, as well, to increase the number and directions of light impinging upon a seed.

[0190] The interiors (not explicitly shown) of MWIR emitters E can comprise heaters; or tubular lamps as previously described, such as a clear halogen heat lamp, which essentially acts as a cartridge heater with a glass or quartz exterior. Alternatively, a preferred embodiment can comprise the tubular MWIR emitters E as shown with an emissive coating, such as a known aluminum oxide ceramic, or MWIR emitters E can comprise copper pipes sprayed with glass, or with aluminum oxide thermal spray. Any high emissivity coating on a thermally heated tube could offer advantages so long as the emissions are as called for in the protocol for the invention, preferably Medium Wavelength Infrared in the range of 2 to 8 micron wavelengths.

[0193] The plurality of MWIR emitters E and associated curved reflectors C shown perform two functions: they illuminate directly the processing theater 4 and associated seeds, shown by the downward Medium Wavelength Infrared MWIR rays; and they heat up the radiant and transmissive seed accumulator belt 3ZE8 so it becomes a MWIR emitter itself, and this is shown by the upward Medium Wavelength Infrared MWIR rays.
[0194] Because the radiant and transmissive seed accumulator belt 3ZE8 is porous to air, and because the external wrap formed by the belt is somewhat hermetically sealed (provisions known to those skilled in the mechanical arts, but not shown), a plurality of expulsion fans Y (of known construction) at the belt underside (a second portion of the belt) as shown allow for a negative pressure or vacuum to be created within the interior of radiant and transmissive seed accumulator belt 3ZE8. This allows for material handling and transporting the seed to and from the processing theater, specifically radiant and transmissive seed accumulator belt 3ZE8. As shown in

[0197] With the growth of large farms utilizing precise seeding intervals in rows, typically 30 inches apart, advanced mechanized farm implements known as agricultural planters or planters are in wide use for sowing seeds. Planters are typically drawn by tractors and can possess a large number of modules or row units that individually deposit seeds at regular intervals. The soil is opened into generally a V-shape trench, using a cutting disc or other mechanism, a seed is dropped or thrown into that trench, and then the trenched is closed using another disc or traveling implement. The John Deere DB120, manufactured by John Deere (Moline, Ill., USA) is the largest in the world, possessing 48 row units. Traveling a 5-5.5 miles per hour ground speed, it can sow 90-100 acres per hour ( 4/10 km.sup.2/hour). Modern planters use planter speed-matching delivery and GPS (Global Positioning System) to assist in advantageous seed drop and aligning of multiple passes of the planter on a field. They also can perform fertilization, such as the ExactRate™ Fertilizer System manufactured by (John Deere, Moline, Ill., USA). The instant invention can be used to advantage to provide rapid pulse programming of seeds before or while they are planted or deposited onto a field, to obtain improved germination probability, increased root mass, and increased crop yield.

[0204] In practicing the invention, one can use intermittent sources, a flash or flashes, without departing from the scope of the appended claims, but overall, irradiances should be kept to less than 7 W/cm.sup.2 average to avoid flash ignition of seeds.
