This study was conducted to estimate the response of some characters of such as

biological yield, grain yield, harvest index and Land equivalent ratio. chlorophyll and

protein content of Araz bread which, intercropped with two legume crops, chickpea and

pea with some different patterns namely [sole wheat, sole wheat + fertilizer, 1 wheat: 1

legume (chickpea or pea) , 2 wheat: 1 legume (chickpea or pea), 1 wheat: 2

legumes(chickpea or pea) and broadcast treatments]. This experiment was conducted at

two different locations Qlyasan and Kanipanka during the winter season 2008 – 2009,

and was designed according to Split Plot Design within factorial experiment with three

replications. As the average of both locations, the response of wheat characters to both

legume crops was significant for biological yield, grain yield and harvest index.

Chickpea had more effect on wheat characters than pea in biological yield, grain yield,

and harvest index. The intercropping systems significantly affected the wheat

characters, biological yield, grain yield, harvest index, LER, flag leaf area, chlorophyll

and protein content. It was found that the cropping system of 1wheat: 2 legumes ( pea ,

chickpea) were more effective on most important wheat characters compared to other

systems, whereas the systems of sole wheat and broadcast exhibited the lowest effect on

most characters. The effect of locations was significant on most important characters

and the Qlyasan location was superior in grain yield only.
