Chemical analysis of fenugreek plant Trigonlla foenum-graecum L. which spray by nitrogen and zinc

Abstract

Biology experiment was carried out during the winter season 2010/2011 in the greenhouse condition at Biology Department, College of Education for pure science, Baghdad University in order to determine the response fenugreek for foliar treatments of metals elements (nitrogen and zinc) and their impact on nutrients content N, P, K, Ca and Mg and carbohydrate concentration. The experiment study of the effect of three concentrations for nitrogen fertilizer are(0,1000,2000mg/l) and zinc sulfate fertilizer are(0,25,50mg/l). The experiment carried out within the system of testing the factorial experiment has been used according to random complete block design(R.C.B.D.) with three replicates . Considered statistically analyzed the data according to the design of experience compared to averages of treatments on the basis of test least significant difference 5% Level of moral study results showed that .The addition of nitrogen fertilizer to significantly increase and 2000 mg/l concentration give values of nutrients content above 54.54, 10.73, 46.86, 48.03 and 21.55mg/gm respectively and carbohydrate concentration 9.28%.The zinc sulfate fertilizer significantly increase and 50 mg/l concentration give values of nutrients content above 42.80, 8.63, 34.04, 39.52 and 18.64 mg/gm respectively and carbohydrate concentration 7.65%. Also interaction was significantly between the concentrations of nitrogen fertilizer and concentrations of zinc sulfate fertilizer and (2000Nmg/l and50Znmg/l) treatments was given best values compared with other treatments.
