“…Microelements, Zn and B are very important, whereby boron affects metabolic processes such as metabolism of nucleic acid, carbohydrates, proteins, indole-acetic acid, synthesis of cell walls, integrity and function of the membrane, and metabolism of phenols [Rehman et al 2015, Havier et al 2016. It is functionally associated with one or more processes of calcium utilisation, cell division, water relations, and it is a catalyst for certain reactions [Tanaka and Fujiwara 2008].…”

The aim of this study was to establish the effect of different seed treatments on germination, and the growth of the embryonic stem and the radicle of tomato and pepper varieties. Four treatments were used in the study: MIX (Coveron + zinc (Zn 0.5%) + boron (B 0.025%)); Coveron; zinc (ZnSO4, Zn 0.5%) and boron (B 0.025%). The treatments were applied on seeds of following four pepper varieties: Šorokšari, Somborka, Kraljica, and Mirtima and three tomato varieties: Rio Grande, Saint Pierre, and Tomato apple of Novi Sad (Novosadski jabučar). Germination and the growth increase of both the embryonic stem (cm) and the radicle (cm) were observed in the germination cabinets and pots containing soil in two laboratories – locations. After the treatment applied to the pepper seeds and testing in the laboratory germination cabinet the following was established: i) the maximum increase in germination of 90% was when the MIX and Zn treatment was applied to seeds, ii) the growth increase of embryonic stems of 2.7cm was recorded when the MIX treatment was applied, iii) the growth increase of radicles of 1.7cm was gained when the Coveron and MIX treatment was applied. Tests performed in pots showed that Coveron was the most efficient treatment. Treatments on tomato seeds during the seed testing in the germination cabinet provided: vi) the germination increase of 13% with the MIX treatment, vii) the growth increase of the embryonic stem of 2.6 cm with the same treatment, vii) the growth increase of 1.7 cm of radicles. Coveron was the most efficient treatment in tests in pots.

“…Scientific literature is scarce on nutrient coating. Most studies are related to the addition of micronutrients such as zinc, boron, and molybdenum to the coating (Albuquerque et al, 2010;Xavier et al, 2016;Acha;Vieira;Freitas, 2016). However, many other nutrients are essential for the development of plants and could be incorporated in the coating.…”

Fertilization is not a common management practice at pasture establishment in Brazil. Seed coating technology can be a useful approach to ensure the availability of nutrients to plants during the early stages of development. Thus, the objective of this work was to investigate the incorporation of liquid fertilizer in seeds of Stylosanthes and to evaluate the effect of this technology on seed quality. Mastermins® fertilizer was applied to the last layer of the binder material coating on the seed and Polyseed 76F polymer adhesive was thereafter applied onto the fertilizer. Physiological and biometric analyses of the seeds were carried out. Six fertilizer doses (0, 10, 20, 30, 40, and 50 mL.100 g seeds-1) were tested, with and without adhesive. The control group comprised of uncoated seeds. The method provided a significant increase in the concentration of mineral nutrients supplemented to the seeds, and the use of the adhesive polymer further increased the concentration of minerals. The liquid fertilizer had no effect on seed emergence and emergence speed but influenced germination and germination speed. The results also showed that fertilizer doses higher than 10 mL.100 g seeds-1 did not provide higher dry mass accumulation in Campo Grande Stylosanthes.

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.
