The Allelopathic Potential of Foliar Application of Aqueous Extracts of Chickpea on Growth and Yield of Chickpea

Abstract

A pot experiment was executed in the college of science, Salahaddin university glass house to investigate the allelopathic potentiality of aqueous chickpea Cicer arietinum L. seed extracts that was foliar sprayed on chickpea plants 45 days after sowing to estimate growth, yield, yield components, and seeds chemical characteristics. Results showed that the allelopathic effect was significant on chickpea plant height, number of pods per plant, seeds per pod, shoot dry weight, seed yield per plant, biological yield per plant, harvest index, hundred seeds weight, nitrogen, protein, and phosphorus content. The allelopathic effect was on its own species, and the effect was percentage dependent which, means increasing extract percentage elevated allelopathic impact. The allelopathic index was at the maximum level when the plants were sprayed with the highest extract percentage.
