Small Plot

1. Two identical small plot experiments were done from 1961 to 1963, at the Hannah Dairy Research Institute, Ayr and at Boghall Farm, Midlothian to study the effects of applying nitrogen fertilizer at different times on total yield and its seasonal distribution.2. Two perennial rye-grass plus white clover swards, one containing S23 and the other S24, were used at each site. On both swards a total of 10 cwt. of ‘Nitro-Chalk’ (15·5% N)/acre, applied at varying dates over the growing season, and a control treatment which received no nitrogen fertilizer were tested.

Effect On Growth

AbstractA field trial in which four homœopathic sprays were applied to rye grass is reported. The aim of the trial was to determine whether any significant effect on growth could be achieved when compared with similar applications of nitrogen fertilizer, and a control. At the particular dosages and strengths chosen no such effect was perceived; however a method for testing homœopathic sprays were established. The results are presented and analyzed. Suggestions are made for further work.

Structural Preservation

Rapid freezing and freeze-substitution have been employed as alternatives to chemical fixation because of the improved structural preservation obtained in various cell types. This has been attributed to biomolecular immobilization derived from the extremely rapid arrest of cell function. These methods allow the elimination of conventionally used fixatives, which may have denaturing or “masking” effects on proteins. Thus, this makes them ideal techniques for immunocytochemistry, in which preservation of both ultrastructure and antigenicity are important. These procedures are also compatible with cold embedding acrylic resins which are known to increase sensitivity in immunolabelling.This study reveals how rapid freezing and freeze-substitution may prove to be useful in the study of the mobile allergenic proteins of rye grass and ragweed. Most studies have relied on the use of osmium tetroxide to achieve the necessary ultrastructural detail in pollen whereas those that omitted it have had to contend with poor overall preservation.

The use of nitrogen fertilizer is becoming a global problem; however continuous fertilization with nitrogen ensures large and constant harvests. An 8 year research (2006–2013) was conducted to evaluate the relationships between differently fertilized cultivated plant rotations. The research was conducted in Lipliunai (Lithuania) in the agroecosystem with nitrogen metabolism in fields with deeper carbonaceous soil, i.e. Endocalcari Endohypogleyic Cambisol (CMg-n-w-can). The research area covered three drained plots where crop rotation of differently fertilized cereals and perennial grasses was applied. Samples of soil, water and plants were investigated in the Chemical Analysis Laboratory of the Aleksandras Stulginskis University certified by the Environment Ministry of the Republic of Lithuania. The greatest productivity was found in a crop rotation with higher fertilization (N32-140). In crop rotation with lower fertilization (N24-90) productivity of cereals and perennial grasses (N0-80) was 11–35 % lower. The highest amount of mineral soil nitrogen was found in cereal crop rotation with higher fertilization. It was influenced by fertilization and crop productivity. The lowest Nmin and Ntotal concentrations in drainage water were found in grasses crop rotation. Crop rotations of differently fertilized cereals increased nitrogen concentration in drainage water. Nmin concentration in water depended on crop productivity, quantity of mineral soil nitrogen, fertilization, and nitrogen balance. The lowest nitrogen leaching was found in the crop rotation of grasses. Cereal crop rotation increased nitrogen leaching by 12–42 %. The usage of all crop rotations resulted in a negative nitrogen balance, which essentially depended on fertilization with nitrogen fertilizer.

El área de Producción del Altiplano de Quetzaltenango identificada como “cadena lechera” está ubicada al Norte del Departamento, incluyendo áreas colindantes de Totonicapán y San Marcos, en altitudes de 2200 hasta 2800m. Con condiciones variadas para tal producción, trabajan en la actividad más de 300 familias de pequeños productores(5 vacas promedio). La intervención institucional se ha dado por: Ministerio de Agricultura, Cooperativa XELAC, ICTA, AID e iniciativa privada en: organización, producción, transformación, mercadeo por las “Buenas Prácticas”.La integración de conocimientos y recursos de Productores y especialistas han producido “Tecnologías Apropiadas”encontradas al caracterizar la Cadena Lechera durante los años 2008-2017: a). Uso de ganado apropiado al medio:animales encastados hasta 3/4 Holstein x Jersey x criollo, en doble o triple cruce (chumeca), logrando adaptaciónal ambiente y alta productividad; b). Las mujeres se encargan en un 80% de casos de la actividad lechera: cuido,ordeña, elaboración de productos artesanales y comercialización; principalmente del “queso de sija” propio de la región;c). Una décima parte de leche cruda se destina a la Industria Lechera, principalmente a la Cooperativa XELAC que elabora productos naturales de alta calidad con tecnología Suiza desde hace 40 años. d). Con la introducción de pastos “europeos” por FAO/MAGA desde 1974 e ICTA/DIGESEPE con el asocio avena/vicia se han trabajado las pasturas en la zona; con la limitante que los pastos “europeos” no producían semilla sexual a 2500 m.s.n.m.; por efecto positivo del cambio climático con aumento de 4˚C en los últimos 40 años más otros factores (luz-lluvia) han posibilitado la producción de “semilla sexual” de Rye Grass (Lollium multiflorum), considerando un beneficio para productores del área desde el año 2010. e) La inocuidad de la leche y derivados es apoyada con equipo adecuado de ordeña, aplicación de BPMS, uso integrado de abono orgánico lombricompost y fertirriego del pasto con “aguas servidas” del establo. Orientando las construcciones al medio y cambio climático. El caracterizar los sistemas de producción conjuntamente: Productor-Beneficiario-Profesional ha sido la constante para lograr la sostenibilidad, utilizando herramientas de Etno-veterinaria y Etno-zootecnia.
