“…The most commonly reported effects of humic acids on plants are related to the root system and involve the formation of lateral roots (Trevisan, Francioso, Quaggiotti, & Nardi, 2010;Baldotto et al, 2011;Jindo et al, 2012;Mora, Baigorri, Bacaicoa, Zamarreño, & García-mina, 2012) and adventitious roots (Baldotto, Baldotto, Soares, Martinez, & Venegas, 2012), root elongation and the formation of root hairs Silva et al, 2011). All these factors increase root mass and surface area, contributing to a greater absorption of water and nutrients (Eyheraguibel, Silvestre, & Morard, 2008).…”

ABSTRACT. This study aimed to evaluate the effects of fertigation with humic substances, with and without the addition of plant extracts, on the root system of the 'BRS Princesa' banana cultivar. The banana crop was cultivated at a spacing of 2.0 x 2.5 m and fertigated using a drip system in a dystrocohesive Yellow Latosol. The experimental design was randomized blocks, in a split-split-plot scheme with five replicates, for the following factors: humic substance doses and presence of a plant extract formulation. The treatments consisted of five doses of humic substances, based on a reference dose of 14.14 L ha , in the presence and absence of plant extract. The variable root length (cm) was subjected to variance analyses to evaluate the effect of the humic substances, either isolated or in interaction with plant extract and soil depth. The use of the plant extract increased the effect of the humic substance on root length but overshadowed its effect for the different doses of humic substance. Root length was not sensitive to increasing humic substance dose with plant extract for doses of up to 42.42 L ha -1 at 0 -0.40 m depth.

“…According to Canellas & Façanha (2004), the mechanisms of action of HSs are difficult to explain, because of the nature and complexity of humic molecules. For Baldoto et al (2012), HSs may have auxin-like hormone effect; thus, at high doses, they may harm plant development. Therefore, this is probably one of the reasons for the negative effects on plant height, root and shoot dry matter and grain yield in the present study.…”

A B S T R A C TThis study evaluated the effect of an organomineral fertilizer enriched with humic substances on soybean grown under water stress. The experiment was performed in a greenhouse using a Red Latosol (Oxisol) with adequate fertility as substrate, in which soybean plants were cultivated with and without water stress. The experimental design was randomized blocks, in a 2 x 5 factorial scheme (two moisture levels and five fertilizer doses: 0, 1, 2, 4 and 8 mL dm -3 ), totaling 10 treatments, with four replicates. The organomineral fertilizer was applied in the soil 21 days after plant emergence and the water regimes were established one week thereafter. The fertilizer was not able to attenuate the effects of water stress, reducing soybean grain yield by more than 50% compared with plants cultivated under no stress. Fertilizer doses caused positive response on soybean nutrition and grain yield and, under water stress condition, the most efficient dose was 5.4 mL dm -3 . There were lower leaf concentrations of nitrogen, phosphorus and potassium and higher concentrations of sulfur in plants under stress. Humic substances favor the absorption of micronutrients.Fertilizante organomineral líquido contendo substâncias húmicas em soja cultivada sob estresse hídrico R E S U M O Avaliou-se, neste trabalho, o efeito de um fertilizante organomineral enriquecido com substâncias húmicas em soja submetida a estresse hídrico. Em casa de vegetação foi realizado um experimento utilizando-se, como substrato, um Latossolo Vermelho com nível de fertilidade adequado no qual foram cultivadas plantas de soja em duas condições, sem e com estresse hídrico. O delineamento foi em blocos casualizados em esquema fatorial 2 x 5 (dois níveis de umidade e cinco doses: 0, 1, 2, 4 e 8 mL dm -3 ) totalizando 10 tratamentos, com 4 repetições. O fertilizante organomineral foi aplicado ao solo 21 dias após a emergência das plantas estabelecendo-se, uma semana após sua aplicação, os níveis de umidade. O fertilizante organomineral não foi capaz de atenuar os efeitos adversos do estresse hídrico reduzindo a produtividade dos grãos de soja em mais de 50% quando comparado às plantas cultivadas sem estresse hídrico. Houve resposta positiva quanto às doses sobre a nutrição e produtividade de grãos sendo que, na condição de estresse hídrico, a mais eficiente foi 5,4 mL dm -3 ; foi menor a concentração foliar de nitrogênio, fósforo e potássio nas plantas com estresse e maior concentração de enxofre; as substâncias húmicas favorecem a absorção de micronutrientes.

The quality of the root system in stem cuttings of Piper nigrum is highly associated with the induction of adventitious roots by means of auxins and type of substrates. The objective of this study was to evaluate the rooting of P. nigrum cv. Bragantina cuttings treated or not with indole-3-butyric acid (IBA) in different substrates. The experiment was conducted in a randomized block design following a factorial 2 x 11 scheme (IBA -0 and 4000 mg kg -1 in talc and 11 substrates), with four repetitions of 16 cuttings each. The auxin increased rooting and improved the quality of the root system. The substrates evaluated presented diverse physical, chemical and microbiological characteristics, interfering significantly in the rooting responses. Substrates (d) -soil + limestone + single superphosphate + potassium chloride + chicken manure and (i) -soil + coffee straw + limestone + single superphosphate are the ones recommended for rooting of pepper cv. Bragantina.
