BACKGROUND Peanut (Arachis hypogaea L.) is an important economic food crop highly appreciated worldwide. Although peanut cultivation has been expanding to dry regions, with water stress during growth stages, current genotypes are not adapted to drought. This study aimed to identify and quantify the full range of polyphenols in five peanut genotypes with different degrees of drought tolerance developed by Embrapa (Brazil) using ultra‐high‐definition accurate‐mass liquid chromatography–electrospray ionization–LTQ‐Orbitrap–mass spectrometry. RESULTS Fifty‐eight polyphenols of the classes hydroxybenzoic acids, hydroxycinnamic acids, flavanols, flavonols and flavanones were identified and quantified using high mass accuracy data and confirmed by tandem mass spectrometric experiments. High‐definition mass spectrometric analyses revealed nine phenolic compounds that have never been reported in peanuts before. Polyphenol assessment using multivariate analysis allowed identification of the level of similarities among the five peanut genotypes studied. CONCLUSION Higher drought‐tolerant genotypes exhibited higher content of flavonoids, which suggests a relationship between these compounds and drought tolerance traits. © 2019 Society of Chemical Industry

“…Peanut is amongst the main oleaginous crops in Brazil, ranking fourth in importance worldwide (Santos et al, 2012). According to CONAB (2018), the national peanut production has increased by 46% from 267.6 thousand tons in the 2005/2006 harvest to 512.9 thousand tons in the 2017/2018 harvest.…”

Managment of sulphur fertilizer in forage sorghum crop cultivated in eutrophic Cambisol with alkaline pH

et al. 2019

View full text Add to dashboard Cite

The objective of this study was to analyze the effect of soil fertilization with sulfur-based fertilizers, sulfate and elemental sulfur forms on biomass production, nutrient characteristics of sorghum and soil chemical properties. The experiment was carried out in a 4 x 4 factorial scheme (four sulfur sources: single superphosphate, agricultural gypsum, elemental sulfur powder and elemental sulfur granulated with bentonite, and four sulfur doses: 0, 40, 80, 120 mgdm-3) using four replications in a completely randomized design, being cultivated in pots under greenhouse conditions. The sorghum was cultivated for a period of 51 days after emergence of the seedlings. The shoot dry mass, shoot macronutrients content, root and soil and pH of the soil were evaluated. There were interactions between sources and sulfur doses in the variables such as shoot dry mass, sulfur in the root, sulfur and calcium in the soil. Elemental sulfur (granulate) showed lower concentrations of phosphorus, sulfur and N:S ratio in the shoot. The concentrations of potassium, calcium and magnesium did not show significant differences, both for the shoot and the root. The pH of the soil was reduced depending on the sources and doses of elemental sulfur. The sources and doses of sulfur did not influence the levels of phosphorus, potassium, and magnesium in the soil. The elemental sulfur in the form of powder is the best source of sulfur for forage sorghum cultivated in soil with alkaline pH.

RESUMOGramíneas e leguminosas competem nos sistemas produtivos, sendo que esta competição depende de suas habilidades específicas para a sua sobrevivência. O objetivo desse trabalho foi avaliar o desenvolvimento inicial de amendoinzeiro sob diferentes densidades de matocompetição com Urochloa. Foi realizado um experimento com delineamento inteiramente casualizado, em esquema fatorial 4 x 5. O primeiro fator foi composto por quatro tipos de gramíneas, ou seja, Urochloa brizantha cv. Paiaguás, Marandu, Piatã e Urochloa ruziziensis; o segundo, por cinco densidades de matocompetição e cinco repetições, totalizando 100 parcelas ou vasos. Após 30 dias da semeadura, foram determinados os seguintes parâmetros: ISPADAíndice spad do amendoim; CEAcondutância estomática do amendoim; DCAdiâmetro de caule do amendoim; APA e APGaltura de planta do amendoim e gramínea; MSPAA e MSPAGmassa seca da parte aérea do amendoim e gramínea; e MSRA e MSRGmassa seca de raiz do amendoim e gramínea. O amendoinzeiro responde de maneira negativa quando submetido a altas densidades de matocompetição com gramíneas do gênero Urochloa. A Urochloa ruziziensis apresentou uma maior matocompetição no desenvolvimento inicial do amendoinzeiro. ABSTRACTGrasses and legumes compete in productive systems, and this competition depends on their specific survival skills. The objective of this work was to evaluate the initial development of peanut under different densities of competition with Urochloa. An experiment was carried out with a completely randomized design, in a 4 x 5 factorial scheme. The first factor was composed of four types of grasses, that is, Urochloa brizantha cv. Paiaguás; Marandu; Piatã and Urochloa ruziziensis, the second factor was composed of five densities of weed competition and five replications, totalizing 100 plots or vessels. After 30 days of sowing, the following parameters were determined: ISPADA -peanut spad index; CEA -stomatal peanut conductance; DCA -peanut stem diameter; APA and APG -plant height of peanut and grass; MSPAA and MSPAG -dry mass of aerial part of peanut and grass and MSRA and MSRG -dry mass of peanut root and grass. The peanut tree responds negatively when subjected to high weed competition densities with grasses of the genus Urochloa. Urochloa ruziziensis showed a greater weed competition in the initial development of the peanut tree.
