“…The results obtained in the present work corroborate in part with those obtained by Azevedo et al (2015), which evaluated the effect of hydrogel rates on rooting of mini-cutting of VM01 and AEC0144 clones (E. urophylla), (vermiculite, charcoal rice husk and coconut fiber (1: 1: 1)). These authors verified that, for the clone VM01, the traits SM, RM, NR, RSL, MRL and RSDM were influenced by different hydrogel rates incorporated into the substrate; for clone AEC0144, this effect was verified only for the SM, RM and MRL traits.…”

“…For each substrate, seedlings were produced with and without hydrogel incorporation. The hydrogel used was the Forth Gel  , at a rate of 2 g L -1 of the substrate (AZEVEDO et al, 2015), incorporated in its dehydrated form. The basis fertilization used was the same used in the nursery seedlings production system (29.16 g of Basacote  and 12.15 g of Yorin master  , for every 14 L of the substrate).…”

“…This product provides an improved water retention to the substrate, making it gradually available to the roots (VICENTE et al, 2015). It is a conditioner able to improve the chemical and physical substrate properties (NAVROSKI et al, 2016a), and its incorporation into the substrate have been used for producing forest seedlings (AZEVEDO et al, 2015;BERNARDI et al, 2012;LIU et al, 2013;MALDONADO-BENITEZ et al, 2011;MEWS, 2014;NAVROSKI et al, 2016bNAVROSKI et al, ,c, 2015SOUSA et al, 2013). The use of hydrogel incorporated to the substrate is a promising alternative for improving the rooting of eucalyptus mini-cuttings, mainly in low-rooting materials (AZEVEDO et al, 2015).…”

A propagação vegetativa exige maior controle sobre o substrato, tendo reflexo qualitativo e quantitativo dentro de toda cadeia produtiva de mudas até o plantio. Este trabalho teve como objetivo avaliar a rizogênese e qualidade de mudas clonais de eucalipto produzidas em três diferentes substratos comerciais com e sem incorporação do hidrogel. A pesquisa foi realizada no viveiro da empresa R&S Florestal, Planaltina, Distrito Federal. Para a produção das mudas foram utilizados os substratos comerciais: Vivatto Slim Plus  , Bioplant  e Tropstrato Florestal  , com e sem hidrogel (2 g L -1 ) da marca Forth Gel  , e o material genético (miniestacas) utilizado foi o clone VM01. Foi utilizado o delineamento inteiramente casualizado (DIC), com seis tratamentos em esquema fatorial 3x2 (três tipos de substrato x presença e ausência de hidrogel), com quatro repetições. Aos 35 dias após a emergência (DAE) avaliou-se a rizogênese das miniestacas e aos 101 DAE foi avaliado o desenvolvimento das mudas. A eficiência do hidrogel para a melhoria da qualidade da rizogênese das miniestacas e desenvolvimento das mudas depende das características físicas e químicas dos substratos.Palavras-chave: minisestaquia, hidrogel, análise de substratos. Abstract:Vegetative propagation requires greater control over the substrate, having a qualitative and quantitative reflection within the entire seedlings production chain until the planting. This work aimed to evaluate the rooting and quality of clonal eucalyptus seedlings grown on three different commercial substrates with and without hydrogel incorporation. The research was carried out at the nursery of the R&S Florestal company, Planaltina, Federal District. For producing the seedlings, the following commercial substrates were used: Vivatto Slim Plus  , Bioplant  and Tropstrato Florestal  , with and without hydrogel (2 g L -1 ), Forth Gel  , and the genetic material (mini-cuttings) used was the clone VM01. A completely randomized design was used, with six treatments in a 3x2 factorial scheme (three types of substrate x presence and absence of hydrogel), with four replications. At 35 days after cutting, the rooting of the mini-cuttings was evaluated, and the seedlings development was evaluated at 101 DAE. The hydrogel efficiency for improving the rooting quality of mini-cuttings and seedlings development depends on the physical and chemical properties of the substrates.

“…The same doses of this hydrogel were also tested by Azevedo et al (2015) on the rooting capacity of minicuttings of different eucalypt clones. The authors concluded that the efficiency of this hydrogel makes it a promising alternative for improving rooting of eucalyptus minicuttings, especially for those clones that naturally have low rooting rates.…”

Abstract:The rational use of water is essentual as it is a finite resource. Consequerntly, studies of methids that minimize water use water are essential. As a result, agricultural hydrogels have been extensively tested in as a means of promoting agriculture improvements because of their water-and nutriente-retention characteristics. However, even though hydrogels are used in several sectors of Brazilian agriculture, there are still very few studies on their applications, the best methods and the quantities to be used. Consequently, there is a need for research into the applicability of this technology in Brazil, so that future research needs can be identified and appropriate decisions made at the production level. Therefore, the aim of this study was to collate currently available information on the applicability of agricultural hydrogels in Brazilian agriculture. Over the last decade, forestry is the sector in Brazil that has most studied and used hydrogels, but others such as fruit-and coffeegrowing have also been involved. The method of applying the polymer in granules directly mixed-in with growth substrates is the most used in the production of seedlings. However, use of hydrated gel at planting sites has also been explored. While synthetic hydrogels are most commonly used, those made of natural materials have great potential due to the low preparation costs and their in-soil biodegradability. The quantities of hydrogel used vary according to the target species, application method and objective.Key words: Water sustainable use. Hydro absorvent polymer. Application. Agricultural cultures.Resumo: A utilização racional da água faz-se necessária uma vez que esse recurso é finito, assim, estudos sobre a produção e minimização do uso da água são essenciais. A partir disso, os hidrogéis agrícolas vêm sendo amplamente testados na agricultura por promoverem benfeitorias às plantas pelas suas características de retenção de água e nutrientes. No entanto, mesmo sendo utilizados em diversos ramos da agricultura brasileira, estudos quanto aos métodos de aplicação e às quantidades utilizadas ainda são escassos, justificando a necessidade de pesquisas que elucidem a aplicabilidade dessa tecnologia, para assim gerar informações que sustentem decisões precisas no nível produtivo e experimental. Portanto, objetivou-se com este trabalho compilar as principais informações atuais quanto à aplicabilidade dos hidrogéis agrícolas na agricultura brasileira. A silvicultura é o setor que mais vem estudando e utilizando o uso dos polímeros hidrorretentores nos últimos 10 anos no Brasil, porém, setores como a fruticultura e a cafeicultura também vêm se destacando. O método de aplicação do polímero em grânulos em mistura direta com substratos é o mais utilizado na produção de mudas, todavia, a utilização do gel hidratado no local de plantio apresenta-se como uma alternativa promissora à agricultura brasileira. Os hidrogéis sintéticos são os mais utilizados, no entanto, os constituídos por materiais naturais têm grande potencial em funçã...
