Research on protein content and total nitrogen and a cob of maize strains by FT-NIR spectrometry.

Using Near Infrared Spectrometry has become lately quite a developed technique in the different physico-chemical parameters of the fe ed as a procedure is extremely elegant and precise use. This paper aims to highlight a way of direct a nalysis method undestructive protein and total nitrogen using near infrared spectrometry in conjun ction with reflected attenuated total. Tests were conducted on samples of maize cob and maize stalks from The Research - Agricultural Development Turda. Samples done at each variant separately. Eac h sample was subjected to destructive method calculations: Kjeldahl method for determinating the protein, and then collected with NIR spectrum. We have built mathematical models for both the cob and stalks, based on these techniques and multivariated analysis allows the determination of an error prediction for the best protein 0.5% and t he total nitrogen of 0.1%.
