“…However, the treatments fungicide + insecticide and polymer + fungicide + insecticide showed phytotoxic effect, with lower percentage than both untreated and polymer coated seeds. To Tunes et al (2012) wheat seeds treated with different doses of Zinc sulfate associated with fungicide, polymer and water to a solution volume of 12 mL. kg -1 seed, did not reduce germination after treatment and storage for six months under uncontrolled conditions of air temperature and relative humidity.…”

-Seeds with high quality are one of the important factors to consider in the crops establishment on field. Therefore, the physical and physiological quality of wheat seeds treated with mixes of micronutrients including zinc and protective products were aimed. The wheat seeds were analyzed in a factorial scheme 5x3x4, with five storage time: 0, 60, 120, 180 and 240 days; three micronutrients: micronutrients 1 (1% Mn; 0.1% Mo; 10% Zn); micronutrients 2 (0.3% B; 0.3% Co; 3% Zn) and no micronutrients, and four protective products: untreated seeds, polymer (Colorseed He), fungicide carboxin + thiram (Vitavax® Thiram 200 SC) + insecticide thiamethoxam (Cruiser® 350 FS) and polymer + fungicide + insecticide. After treatment, the seeds were stored under uncontrolled conditions for 240 days and at intervals of 60 days, the germination, accelerated aging and moisture content were determined. Wheat seeds untreated and treated with polymer have the best physiological performance during storage, regardless micronutrients treatments. The wheat seeds treated with carboxin + thiram + thiamethoxam and polymer + carboxin + thiram + thiamethoxam can be storage up to 120 days, under uncontrolled conditions, regardless micronutrients treatments. The seed treatment does not alter the moisture content of wheat seeds.

“…The coating process is environmentally less aggressive technique, which favors the micronutrient contact with the first issued roots, during the germination and seedlings emergence (Tunes et al, 2012;Corlett et al, 2014). The nutrients, though, must be easily absorbed by the radicular system, in order to propitiate better conditions to a fast and vigorous growth.…”

“…The distribution uniformity, due to small amounts of nutrients applied during the seeds coating process, makes the element stay in direct contact with the emission of the first roots, meeting the demands during the crop initial development and indirectly aggregating value to the seeds (Tunes et al, 2012). The silicon (Si) is a mineral element that bestow several benefits to the plants and has shown positive results during the initial development of barley (Corlett et al, 2014), rice (Tunes et al, 2014;Oliveira et al 2016) and soybean (Rufino et al, 2017).…”

The objective of this study was to evaluate the effect of the of common bean seeds coating with different doses of Si, supplied by the carbonized rice hulls, in its physic, physiologic and sanitary attributes, as well determine the amount of this element absorbed in plants. The experiment was conducted in Laboratory of Seed Analysis belonging to the Universidade Federal de Pelotas-Brazil, during the crop season 2014/2015. For this, common bean seeds of cultivar BRS Expedito were treated at doses of 0, 45, 90, 135 and 180 grams of Si 100 kg-1 of seeds, using a completely randomized experimental design with four replicates The use of different doses of carbonized rice hulls in the seed coat does not alter the physical quality and does not negatively affect the physiological quality of the seeds. Crescent doses of carbonized rice hulls up to 101 g of Si 100 kg-1 of seeds increase the seedlings vigor evaluated by the total dry mass and length of shoot at 21 days after seeding, as well as the Si amount in roots. The root dry mass at 21 days after seeding presents growth reduction with the increase of doses until 104 g of Si 100 kg-1 of seeds, although, without compromising the shoot development and the element accumulation. The different Si doses supplied by the carbonized rice hulls do not control pathogens associated to seeds.

“…Efficiency of treating seeds with Zn depends on the translocation of Zn from seed to plant. Thus, reserves of this micronutrient in seeds are important sources for plant nutrition (Tunes et al, 2012). Some authors consider Zn immobile; while others believed on intermediate mobility of this element to plants, when there is a high supply of Zn.…”

This study was conducted in a laboratory with the aim of evaluating zinc absorption, transport, and use efficiencies in wheat from seeds coated with zinc sulfate. Two batches of wheat seeds (BRS 276) were used, one with high vigor and the other low vigor. The treatments consisted of using the commercial product in the form of zinc sulfate (ZnSO 4). The seeds were coated with levels of 0, 1, 2, 3, and 4 ZnSO 4 per kg of seeds. We also added 3 mL of fungicide (carboxin + thiram), 0.8 mL of polymer and enough water to make up 15 mL of syrup for 1 kg of seeds. The experimental design was entirely randomized with four repetitions. After the treatment, the following indices were calculated based on the plants dry material and nutrient content: Absorption Efficiency, Transport Efficiency, and Use Efficiency. The data showed a positive interaction between seed treatments and polymers, in which seed coatings had a good appearance, coloring, distribution, and product adherence to their surface. The results showed that applying the higher doses of the ZnSO 4 nutrient to seeds cause greater Zn absorption efficiency, lower Zn transport and use efficiencies.
