| Near-Infrared (NIR) spectroscopy gives information about the chemical properties of objects, and it is of particular interest for agricultural and food science applications given its rapid and non-destructive nature. This paper presents a study on the prediction of protein content in whole wheat kernels by NIR, comparing two statistical discriminant analysis techniques, namely PLS-DA and LDA, to classify wheat varieties and protein levels at the farm’s site. Data were collected from 3 varieties collected from 9 farms located in the same region, with a total of 54 samples analyzed. The NIR spectrometer used had a range of 950-1650 nm and it was used to classify different wheat samples according to their varieties and protein level. The optimal spectral... |

| In countries that agricultural fields are small, most farmers sow pea seed by scattering them by hand, which causes to decrease the yield. Thus, the objective of this study was to investigate the performance of a cylinder-type vacuum precision seeder for sowing pea seed in small fields. The effects of vacuum pressure, speed of grease belt and diameter of seed hole were evaluated by examining the mean seed spacing, quality feed index, coefficient of seed distribution uniformity, and miss and multiple indices. The main variables were vacuum pressure (40, 60 and 80 mbar), grease belt speed (2.5, 5 and 7 km h-1) and seed hole diameter (3, 4 and 5 mm). The results indicated that the maximum performance of the metering device was founded at the vacuum... |
