“…Critical levels of sap NO 3 -N declined as the season progressed. This corresponds with critical NO 3 -N recommendations based on standard tissue dry matter analysis (Gardner and Jones 1975;Sisson 1991, 1993;Johnson et al 1995). In many cases, the critical range for sap NO 3 -N widened as the season progressed.…”

“…Sap NO 3 -N levels at the first sampling date were consistently high, irrespective of the fertilizer treatments. A similar lack of early season response to fertilizer N has been observed in trials examining tissue dry matter N levels in potatoes (Gardner and Jones 1975;Porter and Sisson 1991;Lewis and Love 1994). Potatoes tend to accumulate N in the petioles during early growth and this N is later translocated to support tuber growth (Millard and MacKerron 1986).…”

“…Consequently, growers striving to meet the crop's N requirements frequently over-fertilize. Excessive application of nitrogen is uneconomical, environmentally unsound and potentially detrimental to the crop (Gardner and Jones 1975;Westermann and Kleinkopf 1985). Ideally, the grower must match N availability to the crop's needs at each growth stage.…”

Waterer, D. 1997. Petiole sap NO 3 -N testing as a method for monitoring nitrogen nutrition of potato crops. Can. J. Plant Sci. 77: 273-278. Petiole sap NO 3 -N concentrations were tested as a means for monitoring crop nitrogen (N) status and N fertilizer responses in potatoes. An ion specific electrode was used to monitor sap NO 3 -N concentrations of three varieties of potatoes grown with differing amounts of N fertilizer in 1993-1995. Plots provided with varying amounts of fertilizer N applied prior to planting or as a split application were sampled on six occasions through the growing season. Sap NO 3 -N levels were positively correlated with petiole dry matter NO 3 -N levels. Petiole sap NO 3 -N levels reflected rates and timing of N fertilizer application. Sap NO 3 -N levels in the three cultivars showed similar changes with time after planting and increasing N fertilizer rates. However, sap NO 3 -N levels measured under a particular set of conditions were unique for each cultivar. The correlation between yields and sap NO 3 -N levels varied with the sampling date and cultivar. Recommendations were developed for critical sap NO 3 -N concentrations at various stages in the development of the three cultivars.Key words: Ion specific electrode, nitrate, petiole, nitrogen, tissue testing, Solanum tuberosum Waterer, D. 1997. Mesure du N nitrique dans la sève du pétiole comme moyen de suivre l'alimentation azotée chez la pomme de terre. Can. H. Plant Sci. 77: 273-278. L'objet des recherches était d'utiliser la mesure des concentrations de N nitrique dans la sève pétiolaire comme moyen de suivre l'évolution de l'alimentation azotée chez la pomme de terre. Au moyen d'une électrode ionospécifique, nous avons surveillé les concentrations de N nitrique dans la sève chez trois variétés de pomme de terre cultivées de 1993 à 1995 sous divers niveaux de fumure azotée. Des échantillons de tissus étaient prélevés à six reprises durant la saison de végétation dans les parcelles recevant les diverses doses de N en préplantation ou en apports fractionnés. Les concentrations de N nitrique de la sève étaient positivement corrélées avec celles mesurées dans la matière sèche des pétioles. Elles traduisaient, par ailleurs, les doses et les modalités de fumure N. Chez les trois cultivars, elles évoluaient de la même façon selon l'âge de la culture à partir de la plantation ainsi qu'en fonction de l'accroissement de la fumure N. Toutefois, les concentrations de N nitrique mesurées dans un jeu de conditions données étaient propres à chaque cultivar. La corrélation entre les rendements en tubercules et les concentrations de N nitrique de la sève variaient selon le cultivar et selon la date de prélèvement des tissus. L'auteur élabore des recommandations de fumure à partir des concentrations critiques de N nitrique de la sève à divers stades de croissance des trois cultivars.

“…Potatoes that have not received current season nitrogen fertilization generally have lower petiole N values earlier in the season and these values decline rapidly after tuber set (Gardner & Jones, 1975;Porter & Sisson, 1991;Wescott et al, 1991). It has been suggested since the rate of petiole N change during the season so rapid establishing of critical petiole N would be difficult unless the precise age of the plant is known and since the soil NO 3 -N status less fluctuates it might could be the better indicator of the N status of the crop (Doll et al, 1971;Rodrigues, 2004).…”

An Hand von Düngungsversuchen wurde im Lößgebiet von Südniedersachen bei Wintergerste und Winterweizen geprüft, ob der Nitratgehalt in der Halmbasis ein geeignetes Maß ist, den N‐Düngerbedarf zwischen Schossen und Ährenschieben zu ermitteln. Im Hinblick auf die praktische Anwendung durch den Landwirt erfolgte die Nitratbestimmung mit Hilfe eines einfach durchzuführenden Nitratpflanzentestes. Folgende Ergebnisse wurden erzielt: Mit dem Reagenz Diphenylamin‐Schwefelsäure können Nitratkonzentrationen zwischen ca. 200 ‐ 2000 ppm in der FM hinreichend genau erfaßt werden. Diese Methode ist für die Anwendung in der landwirtschaftlichen Praxis geeignet, Im Untersuchungsgebiet enthielten Winterweizen und Wintergerste während des Schossens und Ährenschiebens zwischen 50 ‐ 4000 ppm NO3 in der Halmbasis, obwohl im Frühjahr das N‐Angebot (Nmin + N‐Düngung) einheitlich war. Diese Unterschiede hängen im wesentlichen von der Vorfrucht und der organischen Düngung ab. Zwischen dem Nitratgehalt in der Halmbasis der Pflanzen und der in der durchwurzelten Bodenschicht enthaltenen Nitratmenge besteht ein enger Zusammenhang. Der während des Schossens und des Ährenschiebens ermittelte Nitratgehalt in der Halmbasis steht in Beziehung zum N‐Düngerbedarf. Hieraus wurde eine Empfehlung für die N‐Spätdüngung zu Winterweizen und Wintergerste sowohl hinsichtlich des Zeitpunktes als auch der Höhe der Düngergabe abgeleitet.
