Digital image processing of coated perennial-soybean seeds and correlation with physiological atributes

Abstract

Perennial soybean (Neonotonia wightii) is a Fabaceae with potential to be used in consortium with Poaceae plants to improve pasture quality. In order to add value to perennial soybean seeds and improve their seed distribution, seeds coated with different materials in coating machine were characterized by digital image analysis and physical attributes related to physiological attributes in order to define the ideal amount and material to be used in the coating. Different material quantities were tested, 150 g, 200 g and 250 g, divided into layers, namely: sand, calcium silicate + sand and limestone + sand. Coating promoted maximum increments of approximately 350% in seed mass and significant increases of up to 230% in area, 154% in maximum diameter, 162% in minimum diameter, 167% in contained diameter and 152% in perimeter. The coating was also efficient in reducing the moisture of the pellets by increasing the layers that cover the seeds. The sand + limestone combination resulted in the largest pellets. The combination of sand + silicate did not interfere with plant speed and formation. Thus, it was considered the appropriate material for the coating of perennial soybean seeds.

Studying the Effects of Cold Plasma Phosphorus Using Physiological and Digital Image Processing Techniques

“…Many digital computer vision applications were developed in the early 1960s at Bell Laboratories [ 1 ], the Jet Engines Testing lab, the New England Technical University, the University of Maryland, and a few other research institutions, including satellite imagery, wire-photo specifications converting, diagnostic imaging, videoconferencing, character segmentation, and series of photos enhancement [ 2 , 3 ]. The goal of early image processing was to boost the image's quality.…”

Physical-physiological quality and early performance of sorghum plants under different boron doses via seed

“…Therefore, the technique used in this study was efficient to incorporate this micronutrient into seeds. These results corroborate Acha and Vieira (2020), who coated Brachiaria seeds with B and Zn doses and found an increase in their content as fertilizer doses were raised.…”

“…Table 1 shows that the averages of control treatment were, on average, 11, 10, and 18% lower than those of treatments for MAD, MID, and TSA, respectively. These parameters are related to seed geometry (Figure 1) and are responsible for describing the region occupied by the seed in the image plane (Acha & Vieira, 2020). In short, all treatments increased seed size during coating, which added filling material (dolomitic limestone) and B doses to their surface.…”

“…As coating thickness increases, seeds are more protected against pest attack, both in the field and in storage, delaying their deterioration (Gardarin, Durr, Mannino, Busset, & Colbach, 2010). Coating thickness is also a key factor to add fertilizers, fungicides, and other agricultural additives, which must be placed far from the embryo to avoid toxicity (Acha & Vieira, 2020).…”

Analysis of Arbuscular Mycorrhizal Fungal Inoculant Benchmarks

“…Treated or coated seeds often lack uniformity in the quantity of inoculant received and may be contaminated by other microbes. Thick coatings may also hinder seed germination [ 79 ]. Selection and maintenance of viable inoculants in coated seeds are important areas that need to be addressed [ 80 ], especially for long-term storage.…”
