Guillermo Carnero, Jardín concluso (Obra poética 1999-2009)
No full textSe editan aquí los cuatro libros de poesía que Guillermo Carnero (Valencia 1947) fue publicando a lo largo de una década y que considera una segunda época dotada de entidad propia. Los reúne bajo el título inédito de Jardín concluso (Obra poética 1999-2009), una imagen simbólica que también atraviesa los libros recogidos en Dibujo de la muerte. Obra poética (1966-1990), al cuidado de Ignacio Javier López (Madrid, Cátedra, 1a ed. 1998, 2a ed. 2010). Inaugura esa época Verano inglés (1999), y la continúan Espejo de gran niebla (2002), Fuente de Médicis (2006) y Cuatro noches romanas (2009). El estilo del poeta es inconfundible, su trayecto creativo está plagado de fidelidades e indagaciones, que en este volumen único se manifiestan con una nitidez insospechada. En Jardín concluso la poética del autor se engarza en su propia vida, en una coherencia que se percibe desde el enfoque retrospectivo. Aunque sigan latiendo en lo que el poeta ha publicado después, los cuatro libros de Jardín concluso pertenecen al pasado, forman en sí mismos una historia de amor. La ilustran numerosas imágenes que Guillermo Carnero ha elegido, ampliando considerablemente el alcance de la comunicación. La confluencia de signos verbales y signos icónicos transforma al lector también en un espectador, alguien que puede confrontar su mirada con la del poeta y asombrarse ante la transformación de una vasta competencia cultural en versos emocionados que sobrecogen y deslumbran. En esta edición, junto con las imágenes, el autor añade también al final de sus textos las notas sobre el uso de términos poco comunes o sobre circunstancias que atañen a la creación del poema. A veces esos datos de autor acaban arrojando una paradójica luz sobre el prodigio de la creación poética, tanto más inexpugnable cuanto más abunden las noticias acerca de sus componentes
Guillermo Carnero, "Salvador Dalí y otros estudios sobre arte y vanguardia", Valencia 2007
No full textLa imagen superviviente en "Carta florentina" de Guillermo Carnero: una aproximación
No full textFigura destacada de los Novísimos, Guillermo Carnero (Valencia 1947) continúa con Carta florentina (2018) el trayecto emprendido desde la colecci’on de poemas Verano inglés (1999), cuyo tema es una experiencia amorosa crucial. Relacionado también con Espejo de gran niebla (2002), Fuente de Médicis (2006) y Cuatro noches romanas (2009), este libro vuelve desplegar la enunciación pronominal de la primera persona, tan rehuida en la producción del autor hasta 1990. Con un exquisito estilo culturalista, fundado en una densa red de nexos interartísticos, el yo lírico/empírico de Carta florentina afronta de manera inédita el alcance de la imagen anacrónica o superviviente, en la acepción acuñada por Aby Warburg y actualizada por los Visual Studies
"El cuento de nunca acabar" y "Visión de Nueva York" de Carmen Martín Gaite. Notas en forma de collages
No full textCarmen Martín Gaite made "Visión de Nueva York", a notebook of collages, in New York in the fall of 1980. There are some compositions which are a visual diary of the manuscript "El cuento de nunca acabar", a metanarrative essay that the author was trying to finish among many doubts. Based on the recent hermeneutics of image, the intersemiotic relationships between the visual texts of some collages and the verbal text of the manuscript will be analysed. The medium of the collage, which is mounted with images coming from destroyed surfaces, needs a metavisual language in order to interpret its syntax of the fragment. It is a syntax similar to the structure of the manuscript "El cuento de nunca acabar". There is an iconic analogy between these collages and the literary subject that the author was deeply meditating: the difficulty of communicating the wholeness of experience through the order of verbal representations, always incomplete
Allelopathic evaluation of agronomic crops using crushed mulch of crotalaria [Crotalaria juncea (L.) 'Tropic Sun'], jack bean [Canavalia ensiformis (L.)] and pigeon pea [Cajanus cafan 'Lázaro'] in greenhouses
No full textLos estudios de alelopatía se han incrementado durante las dos últimas décadas por
su importancia en la interacción entre las malezas y los cultivos, así como las rotaciones
de cultivos e interacciones entre los cultivos (Patterson, 1981). Medina y colaboradores
(2011) reportaron que los efectos de algunos abonos verdes están relacionados con la liberación
de sustancias alelopáticas durante la descomposición del residuo y pueden ocurrir
durante el ciclo del cultivo y el cultivo siguiente. De igual manera, Ramamoorthy y Paliwal
(1993) evaluaron el efecto alelopático de extractos del follaje de Gliricidia sepium
sobre la germinación del Sorghum sp. y demostraron que hubo inhibición en la germinación.
Por otra parte, Blanco (2006) y Skinner y colaboradores (2012) afirman que los residuos
de los cultivos de cobertura pueden suprimir o interferir en el establecimiento de los
cultivos comerciales. La cobertura muerta en suelo durante muchos años seguidos afecta
el desarrollo de determinados cultivos agrícolas, así mismo, suprime plantas indesables.Martinez Mera, Eliana Andrea-0000-0003-2094-8061-600Valencia, Elide-dc3b1cff-76cc-4c6a-854c-c1137e956435-0Cuevas, Hugo E.-fad8ed23-e444-4c7d-adc4-35f5661e42d6-

Establecimiento y efecto de intervalo de corte en producción y valor nutritivo de maní rizomatoso perenne en el noroeste de Puerto Rico
No full textTen accessions and two commercial varieties of rhizoma perennial peanut (RPP) (Arachis glabrata Benth.) were evaluated at the Isabela ARS farm in 1991-92 to determine percentage of ground cover (PGC), green forage yield (GFY), dry matter yield (DMY), rhizome fresh yield (RFY), and effects of 6- and 12-wk cutting intervals (CI) on DMY, crude protein concentration (CPC), and in vitro dry matter digestibility (IVDMD). After 36 weeks of growth, no significant differences (P = 0.05) were detected in PGC, GFY, DMY, and RFY among the eight, five, seven, and five most productive RPP, respectively. The DMY/harvest of 17095 and 17097 (2,712 and 2,859 kg/ha) was superior (P = 0.05) at the 6-wk CI; and that of \u27Florigraze\u27, 17095 and 17097 (4,052; 4,148 and 4,747 kg/ha) at the 12-wk CI, respectively. There were no differences in CPC among the six and nine RPP with higher values at the two CI and in IVDMD among the seven RPP with higher values at the 6-wk CI, while 17039 and 17044 were superior (P = 0.05) at the 12-wk CI. Accession 17097 showed the greatest overall potential with an extrapolated annual DMY of about 25 and 21 t/ha, CPC of 192 and 155 g/kg, and IVDMD of 587 and 544 g/kg at the two CI, respectively.Diez accesiones y dos cultivares comerciales de maní rizomatoso perenne (MRP) se evaluaron en la finca Isabela del ARS durante 1991-92 para determinar el porcentaje de cobertura de terreno (PCT), rendimiento de forraje verde (RFV), rendimiento de materia seca (RMS) y rendimiento de rizoma fresco (RRF) y los efectos de intervalos de corte de 6 y 12 semanas en el RMS, concentración de proteína cruda (CPC) y digestibilidad aparente in vitro (DAIV). A las 36 semanas de crecimiento no se detectaron diferencias significativas (P = 0.05) en el PCT, RFV, RWSS y RRF entre los ocho, cinco, siete y cinco mejores MRP, respectivamente. El RMS por corte de 17095 y 17097 (2,712 y 2,859 kg/ha) fue superior (P = 0.05) en el IC de 6 semanas; y el de Fiorigraze, 17095 y 17097 (4,052, 4,148 y 4,747 kg/ha) en el IC de 12 semanas, respectivamente. No se detectaron diferencias en CPC entre los seis y nueve WIRP superiores en el IC de 6 y 12 semanas, respectivamente, y en DAIV entre los mejores ocho MRP en el IC de 6 semanas, aunque las accesiones 17039 y 17044 fueron superiores (P = 0.05) en el IC de 12 semanas. La accesión 17097 mostró gran potencial como leguminosa forrajera con un valor anual extrapolado de 25 y 21 t/ha; CPC de 192 y 155 g/kg y DAIV de 587 y 544 g/kg a IC de 6 y 12 semanas, respectivamente
Efeitos da mistura soja-sorgo e da soja tratada com melaço na qualidade e fermentação da silagem
No full textSoybean [Glycine max (L.) Merr.] harvested at R6 phenological growth stage (PGS) and ensiled [treated with 6% molasses, and 50:50 soybean-sorghum mixture (SSOR)] were assessed. Treatments were ensiled in 15-L micro-silos and sampled after 30-d of fermentation. The soybean-sorghum mixture (SSOR) had highest DMY (4.0 Mg ha-1) and mean values of 32% dry matter (DM), 16% crude protein, 54% total digestible nutrients, 1.13 Mcal net energy for lactation (NEL) kg-1 DM and 103 RFV. These values were lower ((p0.05) than those obtained for soybean alone (S) and soybean with molasses (SM). Highest neutral detergent fiber was observed in SSOR (56%), but difference in acid detergent fiber (35%). The SSOR had mean values of 4.13, 7.82, 2.88, 0.03 and 8.25, pH, and percentage lactic, acetic, butyric and NH3-N, respectively. Silage pH, lactic acid, and NH3-N values of SSOR were different (p 0.05) from both soybean alone and soybean treated with molasses, but acetic acid and butyric acid content differed only relative to soybean (sole crop). As for aerobic stability, there were differences (p0.05) between treatments in pH, with values of 4.75, 4.35 and 4.04 for soybean, soybean-molasses, and SSOR, respectively. However, SSOR silage had the highest (p 0.05) temperature and loss of DM. There was a quadratic relationship (p0.05) between time of exposure and temperature of the silage. Adding molasses and a mixture with sorghum improved (p0.05) fermentation characteristics of soybean silage on pH, organic acids, ammonium equivalent protein (AEP) and NH3-N. From a nutritional standpoint, the addition of molasses appears to be the best option for soybean silage preparation, because it does not adversely affect CP, ADF, NDF nor energy level (TDN and NEL). However, if maximum forage yield is desired the SSOR mixture may be more advantageous
SCREENING COWPEA ACCESSIONS FOR THE SEASONALLY DRY HEAVY CLAY SOILS OF THE US VIRGIN ISLANDS
No full textCowpea [Vigna unguiculata (L) Walp] is adapted to well-drained soils and is also drought tolerant. It is primarily used as a pulse crop. It is such a versatile crop with multiple uses [i.e., vegetable crop (both for the green young leaves, shoots and the green peas)], cover crop, and also as forage. Little information is available on its adaptation to heavy clay soils. The objective of this research was to characterize 25 cowpea pure lines for seedling vigor (i.e., plant height), dry pod yield, forage dry matter (DM) and tolerance to high pH soils (pH>7.5). Replicated field studies were conducted on a mildly alkaline Fredensborg clay (fine carbonatic, isohyperthermic, Typic Rendolls, Mollisol) in 2000. Average plant height ranged from 24 to 62-cm at 56-d after planting. Days to floral initiation ranged from 36 to 62-d after planting, indicating a high variability among lines. Pod yield differed (P<0.05) among lines, with highest pod yield for line IT97K-437-8 (450 kg ha"1). Forage yield also differed among lines (P<0.05) with DM yields exceeding 3,500 kg ha"1 for line IT90K-277-2. Twelve lines exhibited high seedling vigor, excellent forage and seed yield, and low symptoms of iron deficiency. These were selected for further evaluation
Efeitos da frequência de corte na produção de matéria seca e no valor nutritivo das cultivares Camello e Cobra em dias curtos
No full textCultivars Camello and Cobra within the genus Urochloa are adapted to low infertile soils and drought tolerant. Litle is known on its adaptation and yield in the different ecosystems of Puerto Rico. Experiments were conducted at the Agricultural Experimental Station of Lajas and Isabela, University of Puerto Rico, Mayaguez from October 2022 to May 2024. At Lajas, two cutting frequencies (6 and 8 weeks) effects on yield (kg ha-1) and nutritive value [crude protein percentages (CP), acid and neutral detergent fibers (ADF; NDF), and in vitro digestibility (IVTD)] of cv. Camello and Cobra were evaluated. Design was a completely randomized design and data collected was analyzed using SAS statistical program. Means when significant were separated using Fisher LSD. Dry matter yield (DMY) was not affected by CF (p³0.05), but there was a cultivar effect (p£0.05) where cv. Camello (828 kg ha-1) was higher than Cobra. Crude protein, ADF, NDF and IVTD did not differ by CF, but there were differences among cultivars for ADF, NDF and IVTD indicating better fiber and digestibility values for Cobra. At Isabela, to improve DMY and nutritive value, perennial legume Stylosanthes (S. guianensis) and semi-annual Aeschynomene americana were tilled in Camello and Cobra stands. Dry matter yield, botanical composition, CP, ADF and NDF were determined by harvesting every 6-wks. Crude protein, NDF and FDA did not differ among associations. There was no difference between the cultivars regarding dry matter yield (DMY); however, for the legumes, the highest yield and proportion were observed with stylosanthes. A. americana did not persist by the fourth harvest
