How to adjust the configuration of LI-6800 to measure in tomato?
Best insight from top research papers
The configuration of the LI-6800 can be adjusted to measure in tomato by following a simple, economical method using digital images obtained with a standard, commercial camera and free software . The method involves taking photographs of the tomato plants using a digital camera at a specific distance above the center of each area . The resulting digital images are then analyzed using free software such as GIMP 2.2 and IMAGE J . Different methods, such as area (SA), contour (SC), and reclassification (SR), can be used to quantify the percentage of groundcover (PGC) in the images . These methods can be compared with measurements of light interception (LI) obtained with a line quantum sensor at solar noon . The results show a close relationship between LI and estimated PGC, with a linear adjustment and significant correlation coefficients . Different equations may be needed to estimate LI under different soil cover conditions, such as bare soil and plastic mulch .

How to measure the color of tomato paste with a digital colorimeter?5 answersTo measure the color of tomato paste with a digital colorimeter, a colorimeter can be utilized to accurately quantify color and color uniformity. This tool allows for precise measurement of color parameters by analyzing electronic images. Additionally, a color calibration method for digital camera images can be employed to capture quantitative surface color information of agricultural products, including tomato paste. Moreover, the concept of optothermal window (OW) detection can be utilized to assess the color of tomato paste, providing a good correlation between the OW signal magnitude and color-related parameters like colorimetric index L* and tomato paste index (TPI). By combining these techniques, one can effectively measure the color of tomato paste using a digital colorimeter with accuracy and precision.

How to measure Total soluble solid of tomato?4 answersTotal soluble solids (TSS) of tomatoes can be measured using nondestructive near-infrared (NIR) spectroscopy techniques. Several studies have explored the use of NIR spectroscopy to evaluate the TSS of tomatoes. Dongyan Zhang et al. developed prediction models using Vis/NIR spectroscopy in the wavelength range of 900-1400 nm, achieving desirable results with Rp and RMSEP of 0.830 and 0.316 °Brix, respectively. M. Égei et al. also used Vis-NIR spectroscopy, comparing different preprocessing methods and multivariate data analysis techniques. They found that the best predictive ability for SSC was obtained using raw absorbance data and multiplicative scatter correction (MSC) in the Vis-NIR range. Additionally, Nafis Khuriyati et al. developed a nondestructive NIR instrument that successfully determined the SSC of tomato fruits with a correlation coefficient (r) of 0.91 and a standard error of performance (SEP) of 0.73%. These studies demonstrate the effectiveness of NIR spectroscopy for measuring the TSS of tomatoes.
How much cost does it take to run a greenhouse tomato production?5 answersThe cost of running a greenhouse tomato production can vary depending on various factors. In one study conducted in Portugal and Spain, it was found that heating costs for tomato greenhouse crops could range from 2.5 € m to more than 15 € m, depending on the heating system and temperature difference between inside and outside. Another study in Iran estimated a total specific input energy of 116,768.4 MJ ha-1 for tomato production, with diesel fuel and chemical fertilizers being among the highest input energies. In terms of economic analysis, the total cost of production for 1 ha greenhouse tomato production was around US$ 34,939, with a benefit-cost ratio of 2.74. A study in the Mediterranean region of Mersin province found that the total energy requirement for tomato cultivation in greenhouses was 245,246.78 MJ ha-1, with a cost-benefit ratio of 3.06. Overall, the cost of running a greenhouse tomato production can involve expenses related to heating, energy inputs, and other factors, which can vary depending on the location and specific conditions of the greenhouse.
How to simulate processing in tomato samples?5 answersProcessing tomato samples can be simulated using various methods. One approach is to use magnetic resonance (MR) imaging to predict peeling outcomes. By creating a multivariate data set from MR images of tomatoes, peeling outcomes such as "whole peel" or "some skin attached" can be accurately predicted. Another method involves a tomato preserved fruit processing technology, which includes steps such as scalding, peeling, mashing, boiling, and pulping. This process results in a tomato paste that can be spread on glass and dried to obtain a finished product. Additionally, a method of processing tomatoes involves crushing fresh tomatoes, concentrating the crushed tomato product, separating the peels and seeds, packaging the tomato puree, and pasteurizing it. These methods provide ways to simulate the processing of tomatoes and can be used in various applications such as fruit processing and scientific research experiments.
How long and which temperature heat stress application method in tomato experiment?5 answersHeat stress application methods and durations varied across the tomato experiments.
