Amino acid composition is an important feature in determining the nutritional value of wheatgrain for human and animal diets. The main objective of the research is to track how the localizedapplication with seeding, chemical fertilizers micro granulated, under the different type fertilizers,influence the variation in the raw protein and amino acid composition of the grain. The amino acids wereassayed using ion-exchange chromatography after hydrolyzing with 6 M HCl for 24h at 110°C. Rawprotein content from wheat grain was determined by Kjeldahl method, as Kjeldahl nitrogen multipliedwith 6.25. Methionine and cystine were analyzed by using formic acid protection prior to acid hydrolysis.The research takes place in experimental field from U.S.A.M.V.B. Didactic Station from Timisoara andafter that in the research lab of Soil Science and Plant Nutrition Department from Faculty of Agriculture.The experiments are stationary type, with wheat – maize rotation. Field experiences are stationary type,in which to practice wheat-corn rotation. Each plot is subdivided into four repetitions, four variants offertilization placed linearly, one still other, with dimensions 10 x 3.5 m (35m2) The variety used for thisexperiment is Alex wheat (Triticum aestivum L.).The fertilizers used are: 15.15.15 complex mineralfertilizers, N 28 liquid foliar fertilizers, Nitrophoska 13.42.0 micro granulated fertilizers.
