Última Manejo bio-racional de plagas y enfermedades en crisantemo Dendranthema grandiflorum (Ramat.) Kitam. 'Harman'. Colegio de Postgraduados Valencia Luna, Jessica Berenice. El cultivo de crisantemo 'Harman' en la región de Texcoco se ve afectado por diversas plagas y enfermedades que demeritan su producción. En la zona, el uso indiscriminado de agroquímicos sintéticos ha ocasionando la aparición de plagas y enfermedades resistentes, fractura del control biológico natural y generado problemas ambientales y de salud humana. Con el objetivo de proporcionar alternativas para el control de plagas y enfermedades, que además contribuyan a la calidad de flor de corte, se evaluaron los tratamientos: miel de abeja al 2 % (M), nitrógeno + ácidos húmicos (N+AH), S. cerevisiae (SC) y testigo regional (T), bajo un diseño experimental de bloques completos al azar con tres repeticiones. Además, en los tratamientos M, N+AH y SC se...

En México, se riegan con aguas residuales aproximadamente 200,000 ha en diferentes valles intermontanos en la zona del Mezquital. Las aguas residuales utilizadas en el Valle del Mezquital no han recibido ningún tratamiento. Debido al tamaño del área de cultivo de 80,000 ha con antigüedad de 97 años en operación continua, la región es un ejemplo de uso de aguas residuales para riego, que derivan de la zona metropolitana del Valle de México. El Valle del Mezquital se localiza dentro del límite suroeste del estado de Hidalgo (latitud norte 20° 02 ́ y longitud oeste 99° 15 ́). Está situado en lo alto de la meseta mexicana, a 60 km de la ciudad de México con una altitud entre 1,640 m y 2,400 msnm. Está conformado por 27 municipios de los 84 que conforman el...

A total of 102 species and varieties of hydroids and three unidentifiable species are described or mentioned in the present report, which deals principally with hydroids collected in the IberoMoroccan Bay (and adjacent Atlantic), the Strait of Gibraltar, and the Alboran Sea; for revisionary purposes some additional, mainly Atlantic, material had to be included. The material described has been assigned to four families of athecate and 14 families of thecate hydroids. Nearly all species have been illustrated and a permanent slide collection has been made. Where necessary the material described has been compared with type material; ten new (sub)species are described, of which eight from the BALGIM material. Holotypes, and where necessary and/or possible...

Ano: 1992 URL: http://www.repository.naturalis.nl/record/317860 Relationship between Social Capital and Livelihood Enhancing Capitals among Smallholder Farmers in Uganda AgEcon Abenakyo, Annet; Sanginga, Pascal; Njuki, Jemimah M.; Kaaria, Susan; Delve, Robert J.. Social capital is an important characteristic of a community and is one of the components of the asset pentagon of the sustainable livelihood framework. The study aimed at assessing the levels and dimensions of social capital and how social capital influences other livelihood capitals. A Cross-sectional survey of a random sample of 208 households was conducted in Masindi and Hoima Districts in Uganda to assess the current livelihood conditions and strategies for improving rural livelihoods. An Index of social capital was generated using density of group membership and three levels of social capital where generated i.e. high, medium and low. Two dimensions of social capital (bonding and bridging) were considered. Results showed that households with high...

Study on diversity of arthropods in sweet corn was carried out at the National Corn and Sorghum Research Center to determine the diversity and abundance of arthropods in dry season during January-March 2009 and March-May 2009. 210 sample plants were observed by using stratified random sampling technique and data was recorded by visual count method. The species/families/groups and number of arthropods were recorded 4 times at vegetative stage and 3 times at reproductive stage on both crops. Diversity of arthropods was analyzed by Shannon-Wiener diversity index. The results revealed that in the first crop, 34 species/families/groups of arthropod were found and the highest number of arthropods (3,486) was found in at the 6th observation however it also showed...

The objective of this study was to evaluate correlations between production and economic variables of lactating cows on a tropical pasture. The experiment involved ten ¾ Holstein × ¼ Dairy Gyr cows in the middle third of lactation at an average age of 70 ± 4.6 months and an average body weight of 400 ± 55.2 kg. Cows were supplemented with a concentrate feed with different supplement compositions aiming to promote alterations in the animal performance and economic responses. Data were analyzed statistically by Pearson correlations at the 0.95 probability level. No correlations were observed for fat and total solids with economic variables (p > 0.05). Milk yield was positively correlated with (p < 0.05), but had no correlation with FC or MRR (p >...
