Abstract:
In this work, a brief review on nuclear reaction methods aimed at nitrogen assessment in organic matter is given, followed by a detailed application using a deuteron beam and (d,p) and (d,α) induced reactions on 14N to determine nitrogen content in single seeds This study covers the analysis of five wheat and four maize stable varieties, which showed up good (linear) correlation coefficients in comparison with corresponding Kjeldahl nitrogen analysis for each species. This method of analysis turns out to be a fast and non-destructive technique for protein determination in cereals, besides its extendibility to other plant products for human nutrition.
