Abstract: The burial straw layer wheat promoted physical soil and chemical properties. Intercropping may provide a framework to analyse the complexity of the energy flows among the components of agricultural systems and the cycling of nutrients. The aims were to evaluate the influence of wheat straw at ratios, and in addition to an intercropping system of common wheat Triticum aestivum and Lentil Lens culinaris Medic. and sole cultivation. A factorial field experiment was designed with RCBD (4X3) and was conducted with four replications. It was to evaluate the influence of wheat straw at ratios of 0, 5, 10 and 15% equivalent to (0.0, 10.550, 18.600 and 28.360 Kg/m) and in addition to an intercropping system of wheat and Lentil. The results showed that, the application of 5% straw caused significant increase in leaf area index (LAI) in wheat, and chlorophyll a and the total chlorophyll in Lentil. Intercropping between the two crops was found to increase the length of awn significantly, and also resulted in a significant decrease in apical internodes plant-1, neck length of the spike of wheat, number of tillers plant-1, and number of leaves plant-1in Lentil. The effects of the application treatment between wheat straw and intercropping was significant increasing in LAI, the length of awn, in the content of chlorophyll a, and total chlorophyll of wheat and also cause a significant decrease in LAI, in the number of branch plant-1, number of leaves plant-1of Lentil.
