“…The same dose of rice hulls used by those authors promoted a 33% increase in the RL of rice cv. BRS Querência [34]. These findings corroborate ours, in which the coating with CS + PVA promoted an 18% increase in RL, which confirms this effectiveness of calcium silicate in RL.…”

The aim of this study was to evaluate the effect of different seed coatings on the physiological potential of perennial soybean cv. Comum. The following treatments were tested: control (no coating); limestone + polyvinyl acetate (PVA); limestone + sand + PVA; limestone + charcoal + PVA; calcium silicate + PVA; calcium silicate + sand + PVA; and calcium silicate + charcoal + PVA. Seeds were evaluated for water content (WC), maximum diameter (MAD), minimum diameter (MID), 1000-seed weight (TSW), germination test, germination speed index (GSI), average germination time (AGT), emergence, emergence speed index (ESI), average emergence time (AET), shoot length (SL), root length (RL), dry and fresh matter of shoots (SDM and SFM), and dry and fresh matter of root (RDM and RFM). Coatings influenced GSI, AGT, emergence, and ESI, but germination was unaffected. The use of silicate with or without charcoal led to the same AET as that observed in the uncoated seeds. Coatings did not affect SFM, SDM, or RFM. Coating with limestone + sand + PVA or limestone + charcoal + PVA led to increases in SL, SFM, SDM, RFM, and RDM.

“…Similar results were found in coated seeds of barley, wheat and rice (Tavares et al, 2012(Tavares et al, , 2014Corlett et al, 2014;Tunes et al, 2014). However, Oliveira et al (2016) verified that improved Si doses propitiate increase in the number of normal seedlings for FGC in rice.…”

“…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). Considered potentially benefic or utile to crops, it assists in the plants defense against biotic stresses (disease and pests) and abiotic (stresses by water and salt, toxicity to heavy metals, high radiation, high or low temperature and nutrient imbalance) (Barbosa et al, 2015;Debona, Rodrigues, & Datnoff, 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.

“…Based on the results found in Table 4, it was observed that the SDI in Ultra stood out among the others with an average of 0.21 cm in the ST CRU, which in turn was the ST that provided the highest averages among the STs in the studied cultivars. Silva et al (2018) and Oliveira et al (2015) found no statistical difference for the SDI, attributing this result to good quality seeds, a factor that standardizes this variable.…”

The objective of this work was to analyze the performance of soybean seedlings in different seed treatments, with multivariate profiles and canonical interrelationships. The experiment was conducted in the county of Mineiros-GO. The soil was classified as a Quartzarenic Neosol. The experimental design used was a randomized block in a 5x4 factorial, corresponding to the seed treatments (WAT, CRU, FIP, FOR and STA) in 4 soybean cultivars (Bônus, Ultra, Extra and BKS7830), in 4 repetitions. Before sowing, pre-plant burndown was performed. The fertilizer used was 450 kg ha -1 of fertilizer 05-25-15 applied in the furrow and in a single dose next to the seeding. During the conduct of the experiment, the control of pests, diseases and weeds were carried out as they became necessary, respecting good practices and integrated management. The data obtained were submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Uni and multivariate tools were applied. The analyzes were performed on Rbio from R and Genes interfaces. The interaction of soybean cultivars and types of seed treatment led to variations in all analyzes evaluated in soybean seedlings. The best performances were found among the BRS 7380RR cultivars that expressed the highest shoot fresh mass when subjected to seed treatment with Cruiser, whereas the greatest root length was expressed in cultivar Ultra in the Fortenza seed treatment.
