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.

Partial root-zone drying (PRD) is an irrigation technique which consists of alternating the water supply from one furrow to another, and keeping the other one dry during the weekly alternation period. Studies assessing PRD in potato have reported a 30-50% of water savings with no tuber yield redu...

Plant breeders and educators working with the International Potato Center (CIP) needed freely available statistical tools. In response, we created first a set of scripts for specific tasks using the open source statistical software R. Based on this we eventually compiled the R package agricolae a...

According to potato experts from ten Sub-Saharan Africa (SSA) countries working together in a community of practice (CoP) over a 3-years period, potato farmers across SSA can increase their current annual production of 10.8 million metric tons by 140% if they had access to high quality seed along...

Saravia, D.Farfán Vignolo, E.Gutiérrez, R.Mendiburu, F. deSchafleitner, R.Bonierbale, Merideth W.Khan, M.A.[Yield and physiological response of potatoes indicate different strategies to cope with drought stress and nitrogen fertilization.]Yield and physiological response of potatoes indicate different strategies to cope with drought stress and nitrogen fertilization.

Low radiation is one of the most important factors which limits potential yield in potato. Under humid conditions, the dominance of diffuse radiation not only imposes challenges for radiation use efficiency in crops but also limits the water status surveillance through non-invasive methods like i...
