Role of Nitrogen and Zinc in nutritional state of fenugreek plant (Trigonella foenum – graecum L .) .

Abstract

An experiment was carried out in the green house of Biology Department/ College of Education Ibn-Al-Haitham / University of Baghdad by using plastic pots with capacity of 4 Kg soil , the experiment was designed according to a completely randomized design(CRD) with three replications. The experiment was conducted to study the influence of foliar application of four concentrations of Urea(46%)as a source of nitrogen (zero ,500 , 1000 , 2000) ppm , and three concentrations of Zinc Sulphate as a source of zinc (zero,25, 50 ) ppm and their interaction on the elements concentrations (nitrogen , phosphorus , potassium , calcium and magnesium) in the vegetative part of Fenugreek plant cultivar(Indian). The aim was also to assess their effect on (No.of grains/plant)and (seeds yield /plant). Results indicated that foliar application of Urea and Zinc sulphate and their interactions gave significantly effect on the nutritional and the yield status of Fenugreek plant particularly in the case of the concentration 1000 ppm Urea and 50 ppm Zinc sulphate which gave the best values of characteristics studied .
