Raymundo, R.Asseng, SentholdPrassad, R.Kleinwechter, U.Concha, J.Condori, B.Bowen, W.Woolf, W.Olesen, J.E.Dong, Q.Zotarelli, L.Gastelo, M.Alva, A.Travasso, MariaQuiróz, R.Arora, V.Graham, W.Porter, C.H.[Performance of the SUBSTOR-potato model across contrasting growing conditions.]Performance of the SUBSTOR-potato model across contrasting growing conditions.

Soil organic C (SOC), the largest terrestrial C pool, has been shown to be sensitive to agricultural disturbance. In the Andean Puna, agricultural expansion is thought to be jeopardizing the large SOC stock sequestered in its soils. In this paper, we assessed the impact changes in land use have o...


Rolando, J.L.Dubeux, J.C.Pérez, W.Ramírez, D.Turin, C.Ruiz Moreno, M.Comerford, N.Mares, V.García, S.Quiróz, R.[Soil organic carbon stocks and fractionation under different land uses in the Peruvian high-Andean Puna.]Soil organic carbon stocks and fractionation under different land uses in the Peruvian high-Andean Puna.

India aims to produce 125 million tonnes potatoes in 2050 for ensuring food security to its natives and for achieving this massive target the country needs to explore non-traditional areas. Rajasthan in general and Jodhpur district in particular are dominated by the arid climate. The state in gen...


Rana, R.K.Arya, S.Kumar, S.Singh, D.K.Turin, C.Mares, V.Quiróz, R.Kadian, M.S.[SWOT analysis of potato cultivation under arid conditions in western Rajasthan (India).]SWOT analysis of potato cultivation under arid conditions in western Rajasthan (India).

Austral summer frosts in the Andean highlands are ubiquitous throughout the crop cycle, causing yield losses. In spite of the existing warming trend, climate change models forecast high variability, including freezing temperatures. As the potato center of origin, the region has a rich biodiversit...

Quantifying rainfall at spatial and temporal scales in regions where meteorological stations are scarce is important for agriculture, natural resource management and land-atmosphere interactions science. We describe a new approach to reconstruct daily rainfall from rain gauge data and the normali...


Quiróz, R.Yarleque, C.Posadas, A.Mares, V.Immerzeel, W.W.[Improving daily rainfall estimation from NDVI using wavelet transform]Improving daily rainfall estimation from NDVI using wavelet transform

The potato processing industry has developed quickly during the past decade in India, and the demand for processing grade potato tubers has increased accordingly. As a consequence, potato market prices have dramatically risen, particularly in the southern states, where production is still limited...


Rana, R.K.Arya, S.Kadian, M.S.Singh, B.P.Quiróz, R.Monneveux, P.[Socio-economic feasibility of potato cultivation in Andhra Pradesh, India.]Socio-economic feasibility of potato cultivation in Andhra Pradesh, India.

Remotely sensed data are often used as proxies for indirect precipitation measures over data-scarce and complex-terrain areas such as the Peruvian Andes. Although this information might be appropriate for some research requirements, the extent at which local sites could be related to such informa...


Posadas, A.Duffaut Espinoza, L.A.Yarleque, C.Carbajal, M.Heidinger, HalineCarvalho, L.Jones, C.Quiróz, R.[Spatial random downscaling of rainfall signals in Andean heterogeneous terrain.]Spatial random downscaling of rainfall signals in Andean heterogeneous terrain.
Yactayo, W.Ramírez, D.Gutiérrez, R.Mares, V.Posadas, A.Quiróz, R.[Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency.]Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency.

Data acquisition for parameterization is one of the most important limitations for the use of potato crop growth models. Non destructive techniques such as remote sensing for gathering required data could circumvent this limitation. Our goal was to analyze the effects of incorporating ground-base...


Quiróz, R.Loayza, H.Barreda, CarolinaGavilán, C.Posadas, A.Ramírez, D.[Linking process-based potato models with light reflectance data: Does model complexity enhance yield prediction accuracy?]Linking process-based potato models with light reflectance data: Does model complexity enhance yield prediction accuracy?

Carbon accumulation and sequestration in Andean soils are scarcely documented. Carbon contents, carbon stocks, and stability were determined in five Peruvian agroecologies, along a 1,000 km (621 mi) transect covering the arid Pacific coast, the Andean high plateau, and the tropical highland rainf...
