The experiment was carried out in the wooden canopy in the green garden of Biology Department ,College of Education for Pure Science – Ibn AL –Haitham, Baghdad University, during the growing season of 2012- 2013 , to study the influence offoliar application of three concentrations of zinc (0,50,75)mg. L ¯¹ with four concentrations of boron (0, 25, 50, 75) mg. L¯¹ and their interactions on some growth parameters of vegetative part of chickpea plant. The experiment was designed according to Randomized Completely BlockDesign(RCBD)with three replications, results indicated that:-
1- Foliar application of zinc and boron caused a significant increase in the averaye of dry weight for the first harvest, No. of branches. plant¯¹, No. of flowers . plant¯¹ , the relative efficiency of fertilizer for the first harvest , the secondary productivity , the content of each nitrogen , phosphorus andcalcium for the both harvests , percentage of protein for the both harvests and the content of total chlorophyll, compared with the control .
2- The interaction effect between the two elements was significant in the growth parametersand superiority of the treatment 75 mg . L¯¹ zinc and 75 mg. L¯¹ boron in giving the bestvalue. |
