AbstractThis work compares the physiological and yield characteristics of white yam (Dioscorea rotundata – Poir) under Arbuscular mycorrhizal fungi (AMF) inoculation, green manures of Gliricidia sepium, Leucaena leucocephala and other soil amendments. The experiment was conducted on the plot of land that had been overcropped, located at the back of the male Hostel, Federal College of Education, Abeokuta, Ogun State, Nigeria. The land was cleared and heaped at 1m x 1m apart. The experimental design employed was a complete randomized design in 5 replicates. The treatments were Glomus deserticola (GD), Glomus fasciculatum (GF), Gliricidia sepium (GS), Leucaena leucocephala (LL), Poultry manure (PM) and NPK fertilizers. Soils were dug from the heaps, 20 g of the inoculums of AMF (GD/ GF) were poured into the dug hole, seeds were laid on it and covered with soil (for GD & GF treatments). Others were applied at one week after sprouting. Growth and yield Parameters were determined at harvest while relative water and chlorophyll contents were measured forth nightly from 10 weeks after treatment. Data obtained were subjected to ANOVA while means were separated by Duncan multiple range test at P> 0.05. Results showed that growth, yield and physiological characters were enhanced in GD, GD+GF, GS and PM treated plants more than in inorganic fertilizers treated plants. There was a positive significant relationship between white yam’s growth, physiology and tuber yield. The study justifies the use of plant/animal manures and Arbuscular mycorrhizal fungi in place of inorganic fertilizers.

En este documento se destaca la importancia de las especies arbóreas empleadas en la alimentación de animales de interés zootécnico, y cómo las diferentes alternativas de conservación permiten suministrar un alimento de excelente calidad nutricional en periodo de escasez. Como es sabido, la alimentación eficiente es uno de los aspectos más importantes en la producción animal, puesto que de ésta depende no solo el rendimiento zootécnico de los animales, sino también la rentabilidad económica del productor. Para brindar una buena dieta, se deben suministrar alimentos con la cantidad necesaria de nutrientes en las condiciones físicas óptimas para qué los mismos sean utilizados metabólicamente de forma eficiente, y así poder obtener el máximo rendimiento en la producción. El suministro del alimento en forma no convencional permite explorar nuevas alternativas que brinden alimentos de buena calidad. En la búsqueda de fuentes alimenticias de bajo costo en el trópico, se ha incluido la evaluación de follajes arbóreos por su alta disponibilidad; la utilización de harinas de follajes de plantas se ha considerado como opción para la sustitución parcial o total de proteína proveniente principalmente de granos y cereales para la alimentación animal, siendo en la actualidad una de las estrategias de mayor investigación, en donde al facilitar su inclusión en las dietas balanceadas de los animales, se convierte en una alternativa económica que permitirá sustituir en parte el uso de alimento concentrado comercial. Especies arbóreas como el matarratón (Gliricidia sepium), leucaena (Leucaena leucocephala), guacimo (Guazuma ulmifolia), cayeno (Hibiscus rosa-sinensis) y morera (Morus alba) son de interés para el productor debido a su potencial de producción (21.93-30.6 ton/ha/MS).

Las selvas bajas caducifolias proveen recursos importantes a las comunidades, por lo que conocer la percepción de este recurso permite identificar cuáles son las especies más convenientes para iniciar la restauración de su cobertura arbórea y diversidad. A través de entrevistas se determinaron 98 especies útiles en la región costera de Actopan, Veracruz. Los usos más frecuentes fueron leña, construcción, postes, cerca viva, carbón, comestible y medicinal. Se eligieron a Gliricidia sepium y a Leucaena leucocephala para realizar experimentos de germinación y el establecimiento en una plantación en dunas costeras, ubicando plántulas debajo del dosel de los árboles (sombra) y en áreas cubiertas por vegetación herbácea (exposición al sol). La germinación de semillas recién colectadas de L. leucocephala fue de 50% en condiciones de sombra y de sol; sin embargo, conforme pasa el tiempo pierden viabilidad. Las semillas de G. sepium presentaron 75% de germinación en varios de los tratamientos aplicados, además no perdieron viabilidad después de ocho meses de almacenamiento. Para las plántulas la condición más benéfica para su establecimiento fue la de sombra con una supervivencia de 86% para L. leucocephala y de 38% para G. sepium. El uso de hidrogel contribuyó a obtener dicha respuesta durante la temporada de secas, al reducir la necesidad de riego.

Ensiled king grass (Cenchrus purpureus (Schumach.) Morrone) is commonly used as feed in tropical ruminant production. However, ruminant performance can be limited by low nitrogen (N) content in tropical grass silage. A mixed feed of legume–king grass silage may be an option to improve ruminant production. We investigated the effects of feeding an ensiled mixture of king grass forage and foliage of a browse tree legume, either leucaena (Leucaena leucocephala (Lam.) de Wit) or gliricidia (Gliricidia sepium (Jacq.) Walp), on dry matter (DM) intake, DM digestibility, organic matter (OM) digestibility and N balance of Pelibuey sheep. Twelve male lambs 9–11 months old were blocked by initial bodyweight (33 ± 3 kg, mean ± s.d.) into three groups of four lambs and randomly assigned to one of three feed treatments: king grass silage (KS); mixed king grass and leucaena silage (KLS); and mixed king grass and gliricidia silage (KGS). Results showed that DM and OM were similar among silages. The N content was higher (P < 0.001) in KLS and KGS than in KS. DM intake and DM digestibility were higher (P < 0.001) in KLS and KGS than in KS. OM digestibility was higher (P < 0.001) in KLS than in KS. Nitrogen intake, faecal N, urine volume, urinary N, digested N, N digestibility, N retention and retained N:N intake ratio from KLS and KGS treatments were higher (P < 0.05) than from KS. A lower (P < 0.01) urinary N:N intake ratio was detected from KGS and KLS than from KS. This study demonstrated that, compared with silage made from king grass alone, legume–king grass silage mixtures can improve intake and nutrient digestibility in Pelibuey lambs. Further, N retention can be enhanced when legume–king grass silages are used as feed compared with king grass silage alone.

Este trabalho teve como objetivo selecionar espécies arbóreas de uso madeireiro e forrageiro para a região semi-árida do Estado de Sergipe. Foram introduzidas quinze espécies procedentes da região semi-árida da América Central: Acacia farnesiana, Albizia caribaea, Albizia guachepele, Ateleia herbert-smithii, Caesalpinia coriaria, Caesalpinia eryostachys, Caesalpinia velutina, Entervlobium cyclocarpum, Gliricidia sepium, Leucaena diversifolia, Leucaena leucocephala, Leucaena shannoni, Parkinsonia aculeata, Pithecellobium dulce e Senna otomaria. As espécies estudadas foram plantadas no Campo Experimental de Glória, da Embrapa Semi-Árido, no município de Nossa Senhora da Glória, SE. O plantio foi feito em covas de 30x30cm, sem adubação, espaçadas em 3x2m, seguindo o delineamento estatístico de blocos ao acaso com três repetições, com 36 plantas por parcela. Foram avaliadas a sobrevivência, a altura e o diâmetro à altura de l,30m do solo aos 55 meses de idade após o plantio definitivo no campo.. Os resultados mostram que as espécies G. sepium e A. guachepele sobressaíram-se em relação às demais, apresentando, respectivamente, alturas médias (± desvio-padrão) de 4,0±0,4 e 4,3±0,2m, diâmetros médios (± desviopadrão) de 4,4±0,5 e 6,3±0,1cm, com taxas de sobrevivência de 100 e 98%. L leucocephala, embora tenha atingido altos valores médios de altura (5,0±0,3m) e de diâmetro (6,0±l,5cm), apresentou baixa taxa de sobrevivência (44%). Ressalta-se, ainda, a mortalidade de 100% dos indivíduos de L diversifolia e A. farnesiana. As espécies Gliricidia sepium e Albizia guachepele destacaram-se silviculturalmente, com grande potencialidade para áreas semi-áridas do Estado de Sergipe. Acacia farnesiana, Leucaena diversifolia e Senna otomaria não se adequaram às condições semi-áridas da região.

Randomized Block Design

The research compared biomass production and nutrient release in an alley cropping system in two collection methods, the litterbag method and the direct collection method (Morley, Bennett, & Clark, 1964). The system was implemented in 2015 at 2017, at the Maranhão Federal University, Maranhão, Brazil. The experiment was a randomized block design with four treatments, consisting of leucaena+sombreiro (Leucaena leucocephala and Clitoria fairchildiana), leucena+acacia (Leucaena leucocephala and Acacia mangium), gliricidia+sombreiro (Gliricidia sepium and Clitoria fairchildiana) and gliricidia+acacia (Gliricidia sepium and Acacia mangium). In order to determine the remaining dry matter, nutrient release (N, P, K, Ca, Mg and Mn), the decomposition constants and the half-lives times of plant residues, 100 g of fresh material were conditioned in litterbags (50 g of each species), arranged on the soil surface. The second method was done by randomly throwing a collector on each plot in the same dimensions of the litterbags (0.40 x 0.40 m) and collecting the litter. For the two methods samples were collected at 0, 30, 60, 90 and 120 days after the start of the experiment. The litterbags method showed a higher C/N ratio at day 30 up to 120 days, which implies that this method is providing a different environment from the litter, where it would be overestimating the C/N ratio and retarding the decomposition. The G+S and G+A combinations were more rapidly decomposed than the combinations of L+S and L+A. The following order of release was established for the litterbags method: P > N > K > Ca > Mn > Mg, and for the method of collecting the litter: N > P > Ca > Mg > K > Mn.
