Uso del atmómetro y coeficiente de cultivo en la programación del riego en maíz forrajero
La programación del riego es un factor clave para el manejo eficiente del agua en la agricultura. El objetivo del estudio fue programar los riegos con el uso del atmómetro y el coeficiente de cultivo (Kc) en maíz (Zea mays L.) forrajero para evaluar su ...

These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...

Our study emphasises that the long‐term fate of polyploids largely depends on water availability, with high polyploids having a competitive advantage in arid environments. This ultimately highlights the role of functional traits in shaping the competitive dynamics between cytotypes.

Biochar‐Amended Soils: A Water‐Saving Strategy for Quinoa Cultivation in the Andes
ABSTRACT Introduction Previous studies showed that biochar amended soils significantly enhanced the growth and yield of quinoa under water limitations. So it becomes an emerging agronomic strategy to consider for sustainable quinoa production. Biochar can specifically be considered for the area particularly receiving low annual rainfall and more ...

The objective of this research was to evaluate the current and future distribution and conservation status of Neltuma pallida in the Peruvian dry forest under climate change scenarios over the last few years. The findings indicated that the likely range of habitats for N. pallida was shaped by factors such as the average temperature of wettest quarter,

Blind shots: non‐natural mortality counteracts conservation efforts of a threatened waterbird
The assessment of the marbled teal population reinforcement programme in Spain carrying out releases of captive‐bred birds showed that 60% of the mortality is due to non‐natural causes, mostly illegal shooting. To establish a self‐sustaining population, non‐natural mortality should be reduced by 40% and management measures such as prosecution of ...

Aspectos socioeconómicos de la agricultura de riego en la Cuenca Lerma-Chapala
Entre 1990 y 2003, la cuenca Lerma-Chapala sobrellevó varios años de sequía severa que redujeron el lago de Chapala a 14% de su volumen total, lo que puso en riesgo el abasto de agua potable para Guadalajara y generó una gran tensión por su distribución ...
