Engineering properties are important in design and development of seed metering mechanism of planter which is responsible for uniform seed distribution so in this study engineering properties of the hybrid cotton seeds were determined. The conventional method to determine physical size seeds are time consuming and laborious process, whereas size determination using digital image analysis is a fast and time saving method, so in this study two methods were used to determine the physical size of hybrid cotton seeds (conventional and digital image analysis) and the outcomes of both methods were statistically analyzed. In the digital image analysis method, images of seeds were captured at 1258×1280 resolution and processed in Image J software for software estimation. The mean length, width, and thickness of cotton seeds measured with a vernier calliper were 8.55, 5.33, and 4.80 mm, respectively, and the mean length and width measured with digital image analysis were 8.76 and 5.63 mm. The spehericity of the seeds was the same for both methods, i.e., 0.70. In terms of length and width, there was a strong correlation between conventional method and digital image analysis method. The average values of moisture content, bulk density, true density, hundred seed weight, angle of repose of cotton seeds, and mild steel coefficient of friction ranged from 7.97 to 8.35 percent (w.b.), 586 to 591 kgm-3, 1000 to 1008 kgm-3, 10.43 to 10.9 g, 35.26° to 37.95°, and 0.46 to 0.65.
Vernier calliper, digital image analysis, angle of repose and coefficient of friction
In the study strong correlation was found between traditional vernier caliper method and digital image analysis method in terms of length and width of cotton seeds. The average length and width of cotton seeds in digital image analysis was slightly higher than conventional vernier caliper method. The mean value of length, width and thickness using vernier caliper were 8.55, 5.33 and 4.80 mm and the mean value of length and width using image analysis were 8.76 and 5.63 mm. The spehericity of the seeds was same i.e., 0.70 for both the methods. Moisture content, bulk density and true density varied between 7.97 to 8.35 per cent (d.b.), 586 to 591kg m-3, 1000 to 1008 kg m-3. The average weight of hundred seeds was 10.63 g. Angle of repose was varied between 35.26° to 37.95°. Average value of coefficient of friction of mild steel was 0.55.
