Abstract
The experiment was conducted in the wooden canopy in the botanical garden of Biology Department , College of Education for pure science – Ibn AL – Haitham , Baghdad University using clay pots to investigate the effect of foliar spraying with Gibberellic acid in three concentrations (0 ,50 and 100) mg. L¹ and three concentrations of Proline acid(0, 25 and 50)mg. L¹ and their interactions on some vegetative growth as (the content of nitrogen ,phosphorous, calcium and total chlorophyll) and some yield components as ( the lentght of pods , no. of pods . plant¹ , no. of seeds . Plant¹ , wt . of seeds . plant¹ )and the percentage of protein of the seeds of pea plant . The experiment was designed according to Completely Randomized Design(CRD) with three replications. Results indicated that, foliar spraying with Gibberellic and Proline acid caused a significant increase in all growth parameters , and the interaction caused a significant effect where the concentration 100 mg. L¹ Gibberellic acid and the concentration 50 mg. L ¹Proline acid gave the best values for the content of the elements , the length of pods . no. of pods . plant¹ but the concentration 50mg. L ¹ Gibberellic acid and the concentration 50mg. L ¹ Proline acid gave the best value for the content of total chlorophyll on the other hand, the treatment 50mg. L¹ Gibberellic acid and 25 mg. L¹ Proline acid gave the highest values for wt. of seeds . plant¹ , the best value for the seeds protein was in the concentration 100 mg. L ¹ Gibberellic acid and the concentration 25 mg. L¹ Proline acid.
