The role of zinc and boron in growth of chickpea plant Cicer arietinum L.

Abstract

Pots experiment was conducted in the wooden canopy in the botanical garden of Biology Department , College of Education for pure Science, Baghdad University during the growing season 2013 to evaluate the effect of foliar spraying with zinc 0,50,75 mg. L-¹ and boron 0, 25, 50, 75 mg. L-¹ and their interactions on some growth parameters of chickpea plant as relative growth rate, No. of flowers.pot-¹, concentration of nitrogen, phosphrous and calcium. Means were compared by using (LSD) least significant difference test according to the design of the experiment, Completely Randomized Design (CRD) with three replications .Results revealed that foliar spraying with zinc and boron gave a significant effect on the growth parameters of the plant, The interaction between them was significant and the treatment 75 mg . L -¹ zinc and 75 mg .L-¹ boron gave the best values for the relative growth rate and No. of flowers. pot-¹ , but the treatment of 75 mg .L -¹ zinc and 50 mg 1.L-¹ boron gave the best values for the macronutrients.
