ارزیابی برخی ویژگی‌های مورفولوژیکی نخود (cicer arietinum L.) در کشت مخلوط با جو بهاره (hordeum vulgare L.)

Intercropping is considered for increasing and stability of yield in per unit. In order to evaluating the effect of barley/chickpea intercrop in different planting patterns, a field experiment was conducted at the Agricultural Research Station, University of Maragheh in 2013. Experimental design was randomized complete block design (RCBD) with five treatment and six replications. Treatments included intercropping different combinations (1:1,2:1, 3:1, 2:2 row ratios of barley: chickpea) and chickpea monoculture. Some traits including plant height, root lenght, shoot-root ratio, number of flower and branch were measured during growth season. The results showed that the effect of intercropping was significant on number of branch and flower chickpea. The root length, seedling height and shoot-root ratio were not observed significant differences under the barley-chick pea intercropping system as compared to the chick pea sole cropping system. But this traits with intercropping improved. The greatest value number of branch was obtained from 3:1 ratio. Also the greatest value number of flower was obtained from chickpea monoculture, followed by 2:2 ratio. Therefore, our research results suggest that changes in the quality and amount of light in a barley-chick pea intercropping system both directly affect the morphological characteristic of chick pea.
