“…of HS to soil has been found to stimulate seed germination, and increase the growth 70 and yields of a variety of important agricultural species (Eyheraguibel et al, 2008, 71 Puglisi et al, 2009, Lee and Bartlett, 1976, Nardi et al, 2002, Arancon et al, 2006, 72 Piccolo et al, 1993. However, the effect of adding HS to plants and soils varies with 73 the origin and concentration of the HS applied, and the species of plant and soil type 74 to which it is applied (Rose et al, 2014).…”

“…involved in cell respiration, photosynthesis, protein synthesis, water and nutrient uptake, enzyme activities (NARDI et al, 2000;TAHIR et al, 2011) and hormones (TREVISAN et al, 2010), thus stimulating plant growth. Humic substances, when applied directly onto the soil or substrate, have been used for plant production because these substances improve soil fertility and nutrient availability, according to Eyheraguibel et al (2008). Studies on the use of humic substances on fruit species are rarely reported in the literature; however, some investigations have been conducted with papaya (CAVALCANTE et al, 2011b), grape (FERRARA;BRUNETTI, 2008) and watermelon (SALMAN et al, 2005), with promising results.…”

ABSTRACT. The custard apple (Annona squamosa L.), also known as the sugar apple, is a fruit species native to Brazil that has been poorly studied, especially in relation to the effect of humic substances on its fruit quality and yield. An experiment was conducted from December 2010 to November 2011 to evaluate the fruit quality and yield of the custard apple as a function of nitrogen fertilising and the use of humic substances. The experimental design consisted of randomised blocks, with treatments distributed in a factorial arrangement (4 x 2), using four nitrogen doses (0, 100, 175 and 250 g of N plant -1 ) and two humic substance applications (with and without humic substances), with four replications. The fruit yield and fruit characteristics, such as fruit mass, titratable acidity (TA), soluble solids (SS), pulp pH and SS/TA ratio, were recorded. The humic substances and the nitrogen levels significantly affected the soluble solids, titratable acidity and SS/TA ratio, while the pH pulp was only influenced by the humic substances. The humic substances promoted a quantitative increase in the fruit yield of 0.63 ton ha -1 . The fruit quality and yield of the custard apple depend on the nitrogen fertiliser and the interaction of the humic substances. Nitrogen fertilising of 100 g per plant, associated with humic substances, could be recommended for use in the production of custard apples.

“…Eyheraguibel et al (2008) also applied HSs via soil, in corn plants, and observed increase in shoot and root biomass. These authors attributed the benefits to the increment of up to 25% in water use efficiency by the plants that received HSs.…”

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.
