Abstract

In order to assess the above and below ground INTERFERENCE of Wild Oat on wheat, a pot experiment as factorial based on Randomized complete design with 4 replications was carried out. The treatments were including four INTERFERENCE level (no INTERFERENCE, full INTERFERENCE, root INTERFERENCE and Shoot INTERFERENCE) and four wild oat densities (2, 4, 6, and 8 Plant/Pot). The mean of relative yield total (RYT) at full INTERFERENCE and root INTERFERENCE were lower that I. Whereas, at shoot INTERFERENCE was higher than 1. It is showed that the root INTERFERENCE effects on RYT loss was higher than shoot. Based on relative crowding coefficient (RCC) results, the wild oat at full and root INTERFERENCEs was most competitor than wheat, but at shoot competition both species had the same RCC. The wheat plant height at root and shoot INTERFERENCE were lower and higher that control, respectively. At root and full INTERFERENCEs, the falg LEAF AREA, biomass, harvest index, length, volume and dry-wight of roots in wheat were significant decreased compared to control. The biomass, GRAIN YIELD and harvest index of wheat were reduced significantly at shoot INTERFERENCE treatment.
