    CROSS REFERENCE TO RELATED ORDERS
    [001] This application claims the benefit and priority of the co-pending Provisional Patent Application entitled "RIGS FOR ILLUMINATING FIELDS AND METHODS OF ILLUMINATING PLANTS", filed on August 27, 2013, and to which US 61 / 870,358, which is incorporated herein in its entirety by way of reference. BACKGROUND
    [002] The subject of photoperiodism concerns the influence of light and dark periods in the daily 24-hour cycles on life processes in plants. The photoperiod refers to the duration, that is, the length of time of exposure to light, in other words, the period of illumination in the daily 24-hour cycle. Generally speaking, photoperiodic response refers to any morphological, anatomical or physiological response produced in a plant by exposure to some particular photoperiodic cycles (eg, periods of darkness). Flowering is one of those photoperiodic responses that plants can exhibit. However, it is important to note that the photoperiodic response in a photoperiodically sensitive plant is largely dependent on the duration of darkness experienced by the plant during a 24-hour cycle.
    [003] In particular, qualitative short-day (ie, mandatory) plants are those plants that necessarily flower as the nights (ie, dark periods) exceed a certain critical length. In nature this happens when days become shorter as the seasons evolve and the year draws to a close, specifically when plants grow outside the equatorial zone (within which the days and nights have approximately the same length and the length of the night does not vary much). In contrast, long-day plants, and especially qualitative (ie, mandatory) long-day plants will flower only when nights are shorter than a certain critical length.
    [004] An irrigation equipment is a device employed in irrigation or farming in which the device provides plants and crops with water by means of sprinklers. Irrigation equipment can automatically move from a first location to a second location while irrigating plants and crops as the irrigation equipment moves. SUMMARY

    [012] The present disclosure relates to equipment and methods for illuminating short-day plants and, in some embodiments, qualitative short-day plants (ie, mandatory). According to various embodiments, the disclosure described herein can be used to control the photoperiodic response of other types of photoperiodically sensitive plants including quantitative short-day plants, qualitative long-day plants, etc. Before the present disclosure is described in more detail, it is to be understood that this disclosure is not limited to the particular described embodiments, as they may, of course, vary. It should further be understood that the terminology used herein is for the sole purpose of describing the specific modalities and is not intended to be limiting, as the scope of disclosure will be limited only by the appended claims.
    [013] When a range of values is provided, it is understood that each intervening value, up to the tenth of the assembly of the lower limit (unless the context clearly indicates otherwise), between the upper and lower limit of that range, and any other value mentioned or intervening in that mentioned range is considered to be part of the disclosure. The upper and lower limits of these minor ranges may be included in the minor ranges and are also covered within the disclosure, subject to any limits specifically excluded in the aforementioned range. When the mentioned range includes one or both of the limits, the ranges that exclude one or both of these included limits are also included in the disclosure.
    [014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by an individual of ordinary skill in the art to which this disclosure belongs. While any methods and materials similar or equivalent to those described herein may be used in the practice or testing of the present disclosure, preferred methods and materials will now be described.
    [015] As will be evident to those skilled in the art after reading this disclosure, each of the individual modalities described and illustrated in this document has distinct components and features that can be readily separated or combined with the features of any of the other various modalities without departing from the scope or spirit of the present disclosure. Any referred method can be performed in the order of the referred events or in any other order that is logically possible.
    [016] The modalities of the present disclosure will employ, unless otherwise indicated, the techniques of agriculture, botany, and the like, which are within the skill of the art. These techniques are fully explained in the literature.
    [017] The following examples are presented in order to provide elements of common skill in the art with a full disclosure and description of how to perform the methods and use the compositions and compounds disclosed and claimed herein. Efforts are made to ensure accuracy with respect to numbers (eg quantities, temperature, etc.), but some experimental errors and deviations must be taken into account. Unless otherwise noted, parts are parts by weight, temperature is in °C, and pressure is atmospheric or near atmospheric. The default temperature and pressure are set to 20 °C and 1 atmosphere.
    [018] Before the modalities of the present disclosure are described in detail, it is to be understood that, unless otherwise indicated, the present disclosure is not limited to particular materials, reagents, reaction materials, manufacturing processes, or similar, since they may vary. It should also be understood that the terminology used in this document is for the purposes of describing particular modalities only, and is not intended to be limiting. It is also possible, in the present disclosure, that steps may be carried out in different sequence where this is logically possible.
    [019] It should be noted that, as used in the specification and appended claims, the singular forms "a," "an" and "a/o" include multiple references, unless the context clearly states that other way. Thus, for example, reference to "a support" includes a plurality of supports. In this specification and in the claims that follow, reference will be made to a variety of terms which must be defined to have the following meanings, unless an intention to the contrary is evident.
    [020] During the description and claim of matter, the following terminology will be used in accordance with the definitions set forth below. The phrase "short day plant" refers to Stevia rebaudiana, Artemisia annua, Oryza (eg rice), Crocus sativus (saffron), Chrysanthemum (morpholium) (chrysanthemum), Dendranthema grandiflora, Kalanchoe blossfeldiana (flower of fortune), Euphorbia pulcherrima (poinsettia), Pharbitis nil, Cannabis sativa, Glycine max (soybean), Xanthium strumarium, Saccharum (eg, sugarcane), and other similar plants.
    [021] Qualitative short-day (ie, mandatory) plants are plants that necessarily flower as the night (ie, dark periods) exceeds a certain critical length. In nature this happens when days become shorter as the seasons evolve and the year draws to a close, specifically when plants grow outside the equatorial zone (within which the days and nights have approximately the same length and the length of the night does not vary much). In contrast, long-day plants, and especially qualitative (ie, mandatory) long-day plants will flower only when the nights are shorter than a certain critical length.
    [022] Photoperiodically sensitive plants can be freely manipulated (eg, triggered or delayed) by exposing such plants to artificially produced light signals of specific wavelengths during the nights. However, there is no reliable and commercially attractive method of handling different types of photosensitive plants grown in commercial open fields and most experiments were confined in greenhouses or other controller settings. The embodiments of the present disclosure can also solve this problem by using open field equipment to manipulate photoperiodically sensitive plants.
    [023] The embodiments of the present disclosure provide for equipment, systems, and methods for lighting short-day and/or long-day plants. These modalities can be advantageous as it is useful to control the flowering of plants (eg, keep them in a vegetative state or induce flowering, if that is more commercially desirable) while cultivating them in open fields.
    [024] For example, short-day plants flower when they are under nocturnal conditions for a period of time (eg greater than about 8, than about 9, than about 10, than about 11, or that about 12 hours or more). In various embodiments, the equipment (for example, a mobile irrigation equipment) can include a plurality of light sources that can be used to illuminate (also referred to as "light treatment") short day plants during the night hours (by low or no sunlight) so that short-day plants do not register night-light conditions, which might otherwise start a flowering cycle. As a result, short-day plants do not bloom and remain in a vegetative state for longer periods of time. Alternatively, the same mechanism can be used to induce flowering in some short-day plants simply by exposing them to different bands of red light. Furthermore, the same arrangements and approaches can be used to manipulate the flowering of long-day plants.
    [025] From the top-down view, the modalities described in this document allow control of the photoperiodic response (eg, flowering) of photosynthetically sensitive plants (eg, short-day mandatory plants, long-day mandatory plants, etc.) while cultivating in large-scale commercial open fields (eg tens of hectares or more), thus helping to optimize harvest times and yields. In other words, the established photoperiod control tools are taken to the open fields.
    [026] For example, it is desirable to delay the flowering of Stevia rebaudiana since the commercially valuable chemical components of the plant (eg, steviol glycosides) are reduced once the plant begins to flower. Keeping Stevia rebaudiana in a vegetative state allows steviol carbohydrates to accumulate and prevent the development of greater leaf mass. As a result, lighting short-day plants, such as Stevia rebaudiana, once or more during the night hours for short periods of time (eg, about 3 to 5 minutes) prevents or substantially prevents short-day plants. bloom, thus increasing the value of the short-day plant.
    [027] In the case of saffron it is desirable to manage its flowering time by forcing it to flower when it is physiologically ready, and it is commercially more suitable than waiting for the correct season to arrive.
    [028] In addition, some examples of long-day plants to which the disclosure in the present document can be applied to include Trifolium pratense (red clover), Rudbeckia bicolor (yellow daisy), Solanum tuberosum L. (potato), Beta vulgaris ( beets), Spinacia oleracea (spinach), Brassica napus L. (rapeseed, canola oil source) Avena sativa (oats).
    [029] Furthermore, using equipment equipped with a plurality of light sources is easily adapted to current outdoor cultivation methods. For example, equipment used in irrigation can also include a plurality of light sources so that the infrastructure currently used can be used to light plants on short days during the night hours.
    [030] In one modality, light can be polarized, plane polarized, circularly polarized, elliptically polarized or depolarized, or collimated (for example, in a laser beam).
    [031] In one embodiment, light treatment may involve one or more combinations of different light frequencies of polarized or depolarized light from distant violet, red and red spectral bands in a range of light intensities appropriate for the type of short day plant. In one embodiment, red light can be from about 600 nm to 800 nm and violet light can be from about 250 nm to 400 nm. In another embodiment, red light can be from about 600 nm to 700 nm. The final spectral combination required for the extension of the vegetative state or, conversely, for the induction of flowering is specific to a given species, but it is well defined and very narrow. In a particular embodiment, the light can be from about 630 nm to 660 nm or from about 730 to 780 nm. For example, Stevia may be illuminated by a light of around 660nm for a period of time to prevent flowering, while strawberry may also need some violet light treatment. The wavelength and intensity range used can be selected based on the type of short-day plant, environmental conditions, the required photoperiodic response or its absence, and the like.
    [032] As mentioned above, an equipment may include a plurality of light sources fixed to the equipment (for example, main equipment arm). The equipment can include linear equipment or pivoting equipment, both of which are mobile. In one modality, the equipment is irrigation equipment that includes a sprinkler system. In the following discussion, a general description of the system and its components is provided, followed by a discussion of its operation.
    [033] Referring to Figure 1, there is shown an illustration of an irrigation equipment 100, which may be part of a water irrigation system for a field of short-day plants, in accordance with various embodiments of the present disclosure. Irrigation equipment 100 includes a plurality of light sources 103a... 103d (collectively, light sources 106), a plurality of sprinklers 106a... 106c (collectively, sprinklers 106), a support structure 109 (e.g. , a main equipment arm) for the light sources 103 and for the sprinklers 106. In various embodiments, the irrigation equipment 100 may comprise a plurality of wheels 112a... 112b (collectively, wheels 112) for the irrigation system. may be a mobile system. In addition, irrigation equipment 100 may comprise, or may be communicatively coupled, a control circuit configured to control an operation of light sources 103, sprinklers 106, and/or an operation of wheels 112. As mentioned above, the specific design of irrigation equipment 100 may change or vary depending on various factors. For example, for short-day plant crops that use an alternative irrigation system, a mobile equipment, similar to an irrigation equipment without the sprinkler system, can be used to light the short-day plants.
    [034] The light sources 103 can be positioned on the equipment in order to maximize the light treatment of short-day plants. The spacing along the length of the irrigation equipment 100 and/or the height above the short-day plants can be adapted to the specific design of the irrigation equipment 100, the type(s) of crop of the short-day plant, to environmental conditions, and the like. In one embodiment, the light source 103 may include an LED, a solid state plasma lamp, a high intensity discharge (HID) lamp, a fluorescent lamp, an incandescent lamp, a sulfur lamp and/or a laser provided that the selected light source emits light at the desired wavelength (eg, from about 600 nm to 800 nm, from about 250 nm to 400 nm). In one embodiment, irrigation equipment 100 may include 1 to 100 s of light sources 103 depending on the size of irrigation equipment 100.
    [035] In a particular embodiment, the light source 103 is an LED, in which the wavelength of the emitted light can be selected based on the type of short-day plant. As mentioned above, Stevia must be lit at a light of about 660nm for a period of time to prevent flowering and keep the plant in a vegetative state, so an LED that emits light at about 660nm can be used. In one embodiment, more than one type of LED can be used in a light source so that the light source emits light at different wavelengths, which can be advantageous for situations where multiple wavelengths are needed to achieve the desired goal.
    [036] In another embodiment, one or more filters (not shown) can be used in combination with the 103 light sources that emit light in a wide range of wavelengths so that only the desired wavelengths reach the day plants short. As is evident from the above discussion, the specific design of irrigation equipment 100 can vary significantly based on the desired objectives to be achieved, and the various projects, although not specifically referred to, are intended to be covered by this discussion and by the claims of the present disclosure.
    [037] Moving on to Figure 2, a drawing is shown that illustrates a field to facilitate light computations, as described below. For example, it may be beneficial to compute a width of a beam from a light source 103 (Figure 1) and a speed at which a beam of light 203 (eg, emitted from a light source 103) needs to travel through. a field 206. Given the equation:
    where V is the speed of the light beam 203 (in meters per minute), t is the plant illumination time, and Z is the light beam width (in meters), where the width of a beam can be calculated. when V and T are known. Given the equation:
    where L is a length of field 206 (in meters) and T is the time it takes the beam of light 203 to travel through field 206, the speed at which the beam of light 203 needs to travel for all plants. in field 206 are lit with a stipulated time can be calculated.
    [038] In one embodiment, the method for lighting short-day plants includes periodically lighting the plants during night hours (or night light conditions). In one modality, the night hours can be around sunset to sunrise or when the short-day plant is said to experience nocturnal conditions (eg, which can occur when sunlight is less than a certain amount. (which varies from plant to plant), may be before sunset or after sunrise) . In one modality, illumination can occur one or more times during night hours for about 1 second to 10 minutes or more, which includes all time ranges in thirty second increments in it. Also, a flash of light can be added for more than a millisecond. In one modality, lighting is performed periodically during the night hours so that the short day plant is not subjected to night light conditions for more than about 12 hours, than about 10 hours, than about 8 hours, or about 6 hours. The amount of time a short-day plant can be subjected to night-light conditions to induce the flowering mechanism varies from plant to plant, so the method for lighting can be adjusted to match the short-day plant flowering / vegetative cycle.
    [039] In one embodiment, the method may include equipment that moves in a manner that exposes short-day plants in the field to an adequate amount of light from the light source(s) in the equipment to maintain short-day plants in the vegetative state. In one embodiment, the equipment can be moved at a constant rate to illuminate short-day plants with an adequate amount of light from the light source(s). The rate of movement can be determined based on equipment design, the light source used, the intensity of a light source, the type of short-day plant, current night conditions, and the like. In another mode, the equipment is not constantly moving, instead the equipment moves to a first position and is isolated for a period of time and then moves to another position and is isolated for a period of time, and this continues until areas across the field have been lit. In other words, the equipment can be moved a set distance to a certain position in the field to expose short-day plants in that area to an adequate amount of light from the light source(s). Subsequently, the equipment is moved from a defined distance to another position in the field to expose the short-day plants in that area to an adequate amount of light from the light source(s). The movement of the equipment can be conducted until the entire field has been exposed to an adequate amount of light. Exposure time and/or moved distance may depend on equipment design, light source used, light source intensity, short-day plant type, and the like.
    [040] An experiment to determine the extent to which flowering in a Stevia plant can be delayed by lighting the plant to a light of wavelength 660 (red light). The experiment was set up in a cubicle measuring 3 meters by 3 meters for 9 cubic individuals covered with a transparent sheet under which a light source was installed that can produce light with a wavelength of 660 nanometers. The plant cuttings were planted in pots and were lit at midnight every day for a duration of 0 minutes to 10 minutes as indicated in Table 1 below.
    Table 1: Flowering Response to Exposure Time
    [041] The power of the LED lights was also varied from 300 watts to 600 watts. The cubicle was observed on a daily basis and the first flower bloom was recorded. The results in Table 1 convincingly show that lighting plants with a red light of a wavelength of 660 nanometers has an impact by delaying flowering when compared to plants that were not lit.
    [042] It should be noted that ratios, concentrations, quantities, and other numerical data may be expressed herein in a range format. It should be understood that a range format is used for convenience and brevity and therefore should be flexibly interpreted to include not only numeric values explicitly reported as range boundaries, but also to include all individual numeric values or the subranges falling within that range as if each numerical value and subrange were explicitly reported. To illustrate, a concentration range of "about 0.1% to about 5%" should be interpreted to include not only the explicitly stated concentration of about 0.1% by weight to about 5% by weight , but also to include individual concentrations (eg 1%, 2%, 3%, and 4%) and subranges (eg 0.5%, 1.1%, 2.2%, 3.3%, and 4.4%) within the indicated range. In one modality, the term "about" can include traditional rounding according to significant figures of numerical values. Also, the phrase "about 'x' to 'y'" includes "about 'x' to about 'y'".
    [043] It should be emphasized that the modalities of the present disclosure described above are simply possible examples of deployments, and are presented simply for a clear understanding of the principles of this disclosure. Many variations and modifications can be made in the embodiment(s) of the disclosure described above without departing substantially from the spirit and principles of the disclosure. All modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
    [044] Disjunctive language, such as the phrase "at least one of X, Y, or Z," unless specifically stated otherwise, is otherwise understood with context as generally used to present that one. item, a term, etc., which can be either X, Y, or Z, or any combination thereof (e.g., X, Y, and/or Z) . Thus, such disjunctive language is not generally intended, and should not imply that certain modalities require at least one of X, at least one of Y, or at least one of Z for each to be presented.
    [045] It should be emphasized that the modalities of the present disclosure described above are simply possible examples of deployments, and are presented for a clear understanding of the principles of this disclosure. Many variations and modifications can be made to the modality(s) without departing substantially from the spirit and principles of the disclosure.
