Evaluación de Niveles de Nitrógeno y Densidades de Siembra en Cuatro Genotipos de Triticale por Moreira, David

“…Creado por fitogenetistas, más que por el proceso natural de evolución, el triticale es el primer cereal hecho por el hombre. Su importancia agronómica, además de botánica, se debe a que ofrece un potencial tremendo como fuente de grano para llenar la creciente necesidad de alimentos en el mundo (CIMMYT, 1976).…”

Vicia villosa ssp. villosa Roth field emergence model in a semiarid agroecosystem por Renzi Pugni, Juan Pablo, Chantre Balacca, Guillermo Ruben, Cantamutto, Miguel Angel

“…However, under rotations of 1–2 years of pasture followed by 1 year of crop (1:1–2:1), hairy vetch could become a problematic volunteer weed in the winter cereal crop phase. This study aimed to develop a mechanistic model for hairy vetch seedling emergence in order to (i) estimate the natural reseeding of hairy vetch in the pasture phase of the field rotation, or (ii) develop control strategies considering hairy vetch as a volunteer weed in the winter cereal phase. …”

Integrated economic modeling of global and regional micronutrient security por Msangi, Siwa, Sulser, Timothy B., Bouis, Andrew, Hawes, Daniel, Batka, Miroslav

“…The effectiveness of the various biofortification strategies is largely determined by the evolution of regional dietary patterns over time, which show continued reliance on staple food crops among the poor. It suggests that cereal grain-focused biofortification is likely to be most effective in South Asia, while targeting roots and tubers is most effective in Sub-Saharan Africa.…”
