Resumo: |
The experiment was carried out at the University José do Rosário Vellano in areas of the Department of Olericulture and Experimentation, in Alfenas, MG, Brazil, from March, 2, 2009 to June, 11, 2009. The purpose was to study the viability of potato fertirrigation techniques. The design was in randomized blocks in a 2 x 3 x 3 factorial scheme, with a total of 18 treatments and three replications. The factors studied were: fertirrigation (two types: surface and subsurface); nitrogen (three doses: 75, 150, and 225 kg ha-1); potassium (theree doses: 210, 310, and 410 kg ha-1). The characteristics studied were: Full Commercial Production in tha-1 and Average Weight per Tuber in grams. For average weight of tubers two significant interactions were observed only between the nitrogen and potassium factors. Significant effects were observed only for the treatments nitrogen plus potassium, without any interaction with fertirrigtation (surface and subsurface). For Commercial Production no significant interactions were observed between the factors nitrogen and potassium treatments. It was concluded that it is possible to produce potato fertirrigated with the of a localized system, reagardless of being surface or subsurface. |
