The present technology relates to an information processing device capable of obtaining an index effective for a measurement target as an index related to light incident on the measurement target, an information processing method, and a program. The information processing device can obtain an index effective for a measurement target as an index regarding light incident on the measurement target by calculating an effective index representing the degree of light effectively utilized for the measurement target in incident light as an index regarding the light incident on the measurement target, on the basis of a measured value regarding the measurement target which is obtained by sensing performed by a sensor. The present technology can be applied to, for example, an apparatus calculating an index of plants.

The present invention relates to automatic and high throughput smart, robotic, autonomous or driver operated, self-propelled field crops harvester (SPFCH) device of row crops, characterized by the need of selecting harvesting ripen crop, during relative long period of time. Harvesting is done by one or more modular robotic harvesting arms hanged on modular booms. When harvesting orchards fruits the SPFCH comprise at least one hybrid robotic arms equipped with a grabbing hand aimed to grab one or more fruit of a an adjacent fruits and also cut its connecting stem, and arm transporting mechanism that gently collects the fruits and transport them to the SPFCH main accumulation area. When harvesting cotton, the SPFCH of the invention may further comprise vacuum sucking hoses and at least one ginning unit that gin the seed-cotton during harvesting and accumulate the seeds in a self-container, and the lint by bales processed, on board by self-press.

A system and method for selecting plants based on climate data and plant data. The system receives climate data and plant data and selects plants for a geographical division based on the climate data and plant data. The system generates durable plant tags with for the plants that have an icon that identifies the lighting level and watering level of the plants using a color and a number.

The present invention relates to a method for in situ sensing of water stress in a plant by contacting a plant with a biosensor, where the biosensor comprises a material capable of giving a detectable response to changes in local water potential in the plant and detecting the detectable response thereby sensing water stress in the plant. The invention further relates to a method for determining water potential in a substance, a biosensor, a system for determining water potential in a substance, a method for determining water potential in a substance, a water potential measurement computing device, and a non-transitory computer readable medium having stored thereon instructions for determining water potential in a substance.

Systems and methods for determining a mass of a crop by using at least one X-ray scanner is provided. The method includes obtaining at least two scan images of the crop, where a first of the at least two images is obtained along a first plane relative to the crop and a second of the at least two images is obtained along a second plane relative to the crop, and where the first plane is angularly displaced relative to the second plane, registering the first image and the second image, correcting the registered first and second images, and determining the mass of the crop from the corrected first and second images.

This disclosure provides liquid chromatography tandem mass spectrometer (LC-MS/MS) methods and systems for detecting low levels of pesticides and mycotoxins in a test sample. In the disclosed methods and systems, oxalic acid is added to a mobile phase composition of a reverse phase chromatographic separation column. This addition improves the signal for certain pesticides and mycotoxins by a factor of from 1.5 to 9, improving their detection limits in a variety of test samples.

A method for identifying converters from tobacco seedling population. The method includes: 1) sowing and cultivating tobacco seeds to be identified for 45-55 days; sampling a plurality of leaf disks from each of 45-55 days old seedlings; 2) incubating the plurality of leaf disks of each seedling in a sealed container at 37° C. for 10-12 hours, thereby obtaining a plurality of incubated tobacco leaves of each seedling; 3) immersing the plurality of incubated tobacco leaves of each seedling in an extractant, extracting alkaloids and obtaining an extract of each seedling; 4) analyzing the amounts of nicotine and nornicotine in the alkaloids extract of each seedling; and 5) automatically recognizing peaks of the alkaloids extract of each seedling, and calculating the percent nicotine conversion (PNC) and the pseudo percent nicotine conversion (PPNC).

An agricultural baler system includes: an agricultural baler including a bale chamber configured to form a bale from crop material, a crop conveyor configured to feed crop material into the bale chamber, a location sensor configured to output a location signal corresponding to a location of the agricultural baler, and a parameter sensor configured to output a parameter signal corresponding to a measured parameter; and a controller operably coupled to the travel sensor and the parameter sensor. The controller is configured to: determine an area based at least partially on a rake width of a rake and a defined length; determine a parameter distribution in a region of a field having the area based at least partially on the measured parameter and the location of the agricultural baler; and output a field map update signal to update a field map to indicate the determined parameter distribution.
