- Abstract
Amino acid composition is an important feature in determining the nutritional value of wheat grain for human and animal diets. The main objective of the research is to track how the localized application 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 were assayed using ion-exchange chromatography after hydrolyzing with 6 M HCl for 24h at 110°C. Raw protein content from wheat grain was determined by Kjeldahl method, as Kjeldahl nitrogen multiplied with 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 and after 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 of fertilization placed linearly, one still other, with dimensions 10 x 3.5 m (35m2) The variety used for this experiment is Alex wheat (Triticum aestivum L.).The fertilizers used are: 15.15.15 complex mineral fertilizers, N 28 liquid foliar fertilizers, Nitrophoska 13.42.0 micro granulated fertilizers.
