Soybean is the most produced oil crop in the world, with great increase in its annual production as well as great generation of waste from its industrialization. The soybean hulls can be used for the elaboration of products such as carboxymethyl cellulose (CMC), adding high value to this residue and it can be used as a coating polymer in seeds. The objective of this work was to analyze the physiological quality of soybean seeds treated with CMC and fungicide, recording images to verify the effectiveness of the coating in the seeds. The experiment was randomized into factorial scheme 2 × 4 with four replicates, two soybean cultivars M-7110 and M-7739 and four types of coating: without (control), CMC, fungicide and fungicide/CMC. The variables analyzed were: vigor (first count), germination test, accelerated aging, length and dry mass of the radicle and hypocotyl length. The images were made with a scanning electron microscope (SEM) with zoom of 50 and 200 times. The CMC used alone or with fungicide, provided good physiological quality of soybean seeds. In some analyzes there was difference between the cultivars M 7110 and M 7739. The combination of CMC and fungicide provided a better coating on the seeds.

“…For high vigor seeds the decrease according to the increase in spray volumes did not result in germination percentages below 80%, which is the minimum value required for commercialization (MAPA, 2013). Segalin et al (2013) obtained similar results working with soybean seeds treated with spray volumes up to 1400 mL. 100 kg -1 , classified in sieves with different diameters.…”

“…Thus, exploring studies indicate the possibility of using higher spray volumes without the occurrence of negative effects on the physiological performance of seeds (Krzyzanowski et al, 2007). Segalin et al (2013) verified that treating soybean seeds with spray volumes up to 1400 mL. kg -1 did not cause reductions in the physiological quality.…”

Spray volumes in the industrial treatment on the physiological quality of soybean seeds with different levels of vigor

et al. 2017

-The aim of this work was to evaluate the effect of different spray volumes, via industrial treatment, on the physiological quality of soybean seeds with different levels of vigor. The experimental design was completely randomized in a 2x5 factor scheme, with four replications. Factors consisted in two levels of seed vigor (high and low) and five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg -1 ). Products used to obtain the volumes were: fungicide (carbendazin + thiram); insecticide (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulants (kinetin + gibberellic acid) and inoculum (Bradyrhizobium japonicum). The used cultivars were BRS 360 RR and BRS 1010 IPRO. The physiological seed quality was determined by the following evaluations: germination, first count of the germination test, seedling emergence in sand, emergency speed index, total length of shoot and root of the seedlings. In the different spray volumes, high vigor soybean seeds have higher physiological quality than low vigor seeds. The increased spray volumes in seed treatments reduce the physiological quality of low vigor soybean seeds.

“…Such recommendation is based on studies with aqueous solutions; however, current seed-coating mixtures are composed of different products already formulated in a liquid medium, whose osmotic potential is thus different from the aqueous solutions evaluated in that study. Recently, Segalin et al (2013) affirmed that volumes of up to 1400 mL. 100 kg -1 of seeds have already been tested in the soybean crop and did not cause damage to seed quality.…”

The aim of this study was to evaluate the effect of industrial seed treatments on the physiological potential of soybean seeds over storage. Four mixtures of agrochemical products in association with two fertilizers were tested. The agrochemical product mixtures were carbendazim/thiram + imidacloprid/thiodicarb; pyraclostrobin, thiophanate-methyl, and fipronil; thiophanate-methyl/fluazinam + bifenthrin/imidacloprid; and metalaxyl-m/fludioxonil + thiamethoxam. The two fertilizers were 7% N, 16% P2O5, 0.6% Co, and 2.5% Mo; and 1% Co, 10% Mo, and 7% P2 O5. The experiment was carried out in a completely randomized design in a split-plot arrangement in time, with four replications. The treatments were allocated in the plots, while the storage periods (0, 30, 60, 90, and 120 days) constituted the split-plots. The following tests were carried out in each period: first count of germination, germination, accelerated aging, emergence speed index in sand substrate, and final seedling emergence in sand substrate. Seed germination and vigor declined over the storage period, especially after industrial treatment. Pesticide mixtures of a carbendazim/thiram fungicide base and an imidacloprid/thiodicarb insecticide base most impaired seed physiological potential throughout storage, regardless of fertilizer use in the industrial treatment.
