The aim of present study was conducted was to increase productivity of exiting cropping systems and farmers income by expanding potato in non-traditional potato growing regions by adopting an innovative technology Double Transplanting (DT) of Rice and planting early maturing potato between two ri...


Arya, S.Ahmed, M.Bardhan Roy, S.K.Kadian, M.S.Quiróz, R.[Sustainable intensification of potato in rice based system for increased productivity and income of resource poor farmers in West Bengal, India]Sustainable intensification of potato in rice based system for increased productivity and income of resource poor farmers in West Bengal, India

India has experienced rapid growth in potato production during recent past and the country has almost doubled its potato production during 2003–2013. The potato productivity improved 31.4% over this period of time. However, potato production scenario in southern states of India is quite grim and ...


Rana, R.K.Arya, S.Kumar, S.Singh, B.P.Adinarayana, G.Kumar, S.Quiróz, R.Kadian, M.S.[Benchmarking farmers' economic and social status in Anantapuramu and Kurnool arid districts of Andhra Pradesh for probable introduction of potato crop.]Benchmarking farmers' economic and social status in Anantapuramu and Kurnool arid districts of Andhra Pradesh for probable introduction of potato crop.

The definition of irrigation schedules depends on the understanding of the response of key plant traits to different water restriction characteristics with the aim to avoid physiological impairment. In this study, different timings (at tuber initiation and bulking) and intensities (four soil mois...


Ramírez, D.Yactayo, W.Rens, L.R.Rolando, J.L.Palacios, S.Mendiburu, F. deMares, V.Barreda, CarolinaLoayza, H.Monneveux, P.Zotarelli, L.Khan, A.Quiróz, R.[Defining biological thresholds associated to plant water status for monitoring water restriction effects: Stomatal conductance and photosynthesis recovery as key indicators in potato.]Defining biological thresholds associated to plant water status for monitoring water restriction effects: Stomatal conductance and photosynthesis recovery as key indicators in potato.

In this paper, a multifractal downscaling technique is applied to adequately transformed and lag corrected normalized difference vegetation index (NDVI) in order to obtain daily estimates of rainfall in an area of the Peruvian Andean high plateau. This downscaling procedure is temporal in nature ...

Rolando, J.L.Ramírez, D.Yactayo, W.Monneveux, P.Quiróz, R.[Leaf greenness as a drought tolerance related trait in potato (Solanum tuberosum L.).]Leaf greenness as a drought tolerance related trait in potato (Solanum tuberosum L.).

LEDFLEX is a micro-lidar dedicated to the measurement of vegetation fluorescence. The light source consists of 4 blue Light-Emitting Diodes (LED) to illuminate part of the canopy in order to average the spatial variability of small crops. The fluorescence emitted in response to a 5-μs width pulse...

Agricultural UAV-based remote sensing tools to facilitate decision-making for increasing productivity in developing countries were developed and tested. Specifically, a high-quality multispectral sensor and sophisticated-yet-user-friendly data processing techniques (software) under an open-access...
