Efecto de siete densidades de siembra sobre el crecimiento y rendimiento del cultivo de Ajonjolí (Sesamum indicum L.) variedad Cuyumaqui

El presente trabajo se estableció con la finalidad de determinar el efecto de siete densidades de siembra (96 150; 104 163; 113 632; 119 043; 128 200; 138 884 y 151 510 plantas 1 ha) sobre el crecimiento y rendimiento del cultivo de ajonjolí (Sesamum indicum L.) variedad Cuyumaqui, bajo las condiciones ecológicas de la finca la Concepción, Nagarote, León. El ensayo se estableció en postrera de 1999, utilizándose un diseño de bloques completos al azar con cuatro repeticiones. Los tratamientos ejercieron efectos significativos sobre las variables plantas cosechadas, plantas acamadas y rendimiento de grano. El máximo potencial de rendimiento se logró con el tratamiento D (119 043 plantas 1 ha) cuyo arreglo de siembra fue de 0.70 m entre surco y 0.12 m entre planta. Cuando se disminuyó la distancia entre surco por debajo de 0.70 m, sin variar la distancia entre planta (0.12 m), la densidad de plantas se incrementó por encima de las 119 043 plantas 1 ha, lo que produjo disminución significativa del rendimiento.

Manejo de mosca blanca (Bemisia tabaci Gennadius.) y Geminivirus en semilleros de tomate (Lycopersicum esculentum Mill.) bajo protección física y química y su efecto en la producción

La mosca blanca (Bemisia tabaci Gennadium) (Hemiptera: Aleyrodidae) es la principal plaga que afecta al tomate (Lycopersicum esculemtumMill.) cultivado en el municipio de Tisma, Masaya. Este insecto transmite geminivirus al tomate y provoca severos daños al cultivo, reduciendo los rendimientos y aumentando los costos de producción. Con el objetivo de evaluar alternativas de protección físicas y químicas contra el ataque de este complejo mosca blanca–Geminivirus se realizó un estudio en semilleros de tomate en el municipio de Tisma, Masaya, en el período entre Noviembre del 2007 a Enero del 2008. Los tratamientos que se compararon fueron: Semillero de tomate sembrado en era y protegido con malla antivirus (Microtúnel), semillero de tomate sembrado en bandejas protegido con un microinvernadero, semillero de tomate sembrado en era al aire libre protegido con gauchoconfidor, semillero de tomate sembrado en era al aire libre protegido con aceite de Neem y semillero de tomate sembrado en era al aire libre y sin ningún tratamiento (Testigo). Las variables evaluadas fueron: número de adultos de mosca blanca por planta, porcentaje de incidencia y severidad de virosis y rendimiento en kg/ha, los muestreos se realizaron semanalmente. De acuerdo a los resultados obtenidos en este estudio, las plantas de tomate que fueron protegidas en etapa de semilleros con microtúnel y microinvernadero presentaron los menores porcentajes de incidencia y severidad de virosis, seguidos por los tratamientos gaucho-confidor y Neem. De la misma manera los tratamientos microtúnel y microinvernadero resultaron con los mejores rendimientos por hectárea, la mejor tasa de retorno marginal y mejores beneficios netos por hectárea.

A note on freshwater research in China, with some observations on the algae from Doupe Pool, Guizhou Province

This article provides insights into a particular aspect of freshwater research in China and its wider implications for western researchers. The senior author has collaborated with Professor Zhang Zhaohui from Guizhou Normal University to investigate the travertines of China. Travertines are freshwater carbonate deposits accumulating in hard-water springs and rivers. In some areas they develop rapidly, forming picturesque ascades and magnificent travertine-dammed lakes. Some of China's most famous tourist sites are the result of travertine formation. The travertine-depositing environment is a unique fast-flowing ecosystem inhabited by specialist plants and animals. The authors examine the freshwater algae of the Doupe Pool travertine situated on the Beishuihei River in Guizhou Province and compare their distribution on travertines elsewhere in the world.

The Political Economy of the 2014-2020 Common Agricultural Policy: An Imperfect Storm. CEPS Paperback, 17 August 2015

After five years of debates, consultations and negotiations, the European institutions reached an agreement in 2013 on the Common Agricultural Policy (CAP) for the 2014-2020 period. The outcome has major implications for the EU’s budget and farmers’ incomes but also for Europe’s environment, its contribution to global climate change and to food security in the EU and in the world. It was decided to spend more than €400 billion during the rest of the decade on the CAP.The official claims are that the new CAP will take better account of society's expectations and lead to far-reaching changes by making subsidies fairer and ‘greener’ and making the CAP more efficient. It is also asserted that the CAP will play a key part in achieving the overall objective of promoting smart, sustainable and inclusive growth. However, there is significant scepticism about these claims and disappointment with the outcome of the decision-making, the first in which the European Parliament was involved under the co-decision procedure. In contrast to earlier reforms where more substantive changes were made to the CAP, the factors that induced the policy discussions in 2008-13 and those that influenced the decision-making did not reinforce each other. On the contrary, they sometimes counteracted one another, yielding an ‘imperfect storm’ as it were, resulting in more status quo and fewer changes. This book discusses the outcome of the decision-making and the factors that influenced the policy choices and decisions. It brings together contributions from leading academics from various disciplines and policy-makers, and key participants in the process from the European Commission and the European Parliament.
