This study was designed to evaluate the role of growth regulator trinexapac and fungicides on growth, yield, and quality of winter rapeseed (Brassica napus L.). The experiment was conducted simultaneously at different locations in Germany using two cultivars of rapeseed. Five different fungicides belonging to the triazole and strobilurin groups, as well as a growth regulator trinexapac, were te...

Dada amplia variación ambientes, una alternativa para definir el ciclo madurez planta sido uso del tiempo térmico acumulado (TTA). Esta medida permite predicción y proporciona apoyo duración fenología, siendo útil manejo mejoramiento cultivos. Este estudio tuv...

Chestnuts (Castanea spp.) are ecologically and economically important forest fruit trees. They cultivated for their nutritious nuts. To select varieties to be in chestnut orchards, phenology needs considered. In this work, we adapt the international BBCH system chestnuts by building on an existing phenological scale used some European countries these species. The proposed uses eight of ten prin...

This study was conducted to examine effects of ensiling, toasting or ensiling plus in partial-crop field peas and faba beans harvested each with 375 g dry matter/kg (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale 79 81, respectively) on gas production post-ruminal crude protein (PRCP) concentration by vitro incubation ruminal fluid batch-cultures. The silages ma...

Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other i...

Although the nitrogen nutrition index (NNI) is a widely used indicator of plant nitrogenstatus, no model of NNI calculation for spring barley (Hordeum vulgare) reflecting also specificmalting requirements on grain has been published. The aim of this study was to determinean optimal range of the nitrogen nutrition index (ratio of nitrogen concentration in shootbiomass to critical nitrogen concen...
