Abstract
Pot experiment is carried out at the greenhouse belongs to the college of Education-university of Al-Anbar during Winter season 2013/2014 to investigate the effect of application of different levels of bat guano (0, 4 and 8gm) on some yield traits for two bread wheat Triticum aestivum L. Cvs, one is local cv. (Aliz) another one is imported from Australia (Eratom). The experimental treatments are distributed according factorial experiment arrangement using completely randomized blocks with three replicates. Some traits are measured as spikes no per plant, spike length, spike weight, grains nos. per spike and grains weight per pot. Results reveal that bat guano application of 8gm is significantly superior in the average of. It thus could be concluded that the application of bat guano at 8gm alone is the better than 4gm in some traits. However, the genetic affinity of local cv is dominated with 4gm application and of imported cv is to 8gm application. Therefore, it could be recommended to test the application of bat guano on the two cultivars across field environment.
