Abstract
Two experiments were carried out in Biology department/College of Education for pure Science–University of Diyala, during agricultural season 2014–2015 to study the effect of allelopathy of some summer plants on growth and yield of wheat. The first experiment was conducted in the laboratory using a Completely Randomized Design (CRD), with three replications to investigate the effects of roots extracts of summer plants (maize, sorghum, sunflower and cotton) in percentage of germination and some characteristic of seedling growth. The second experiment was in pots to study the effects of roots residues of maize, sorghum, sunflower and cotton on growth, germination and yield of wheat which was planted after them, according to the Randomized Complete Block Design (R.C.B.D) with four replicates. The results showed a significant decrease in seed germination of wheat reached to (33.333, 86.667, 73.333 and 26.667%) respectively, as compared with control treatment 93.33% as well as length of leave and roots of the plant and weight of dry matter at transaction with warm water solutions to roots of the summer plants above mentioned with concentration 100%. The results of pots experiment also showed a significant decrease in seed germination of wheat. While, there was significant increase in the percent of fertile branches and plant height which was planted after sorghum, weight of 100 grain and yield of grains plant in wheat which was planted after sunflower.
