Abstract

In order to research effect of DENSITY and row intercropping different ratios on yield two cultivars WHEAT, a factorial experiment based on randomized complete block design with three replications was conducted in Ardabil Agriculture Research station in 1999. Factors were: WHEAT cultivars (dwraf MV-17 almost 65 centimeters and tall Alvand almost 110 centimeters) with three densities (450 seeds m-2 or lower than standard, 500 seeds m-2 or standard and 550 seeds m-2 or higher than standard) and six levels of plating (0; 100, 20:80, 40:60, 60:40, 80:20, 100:0).Mean comparison of INTERCORPPING using LSD method showed that MV-17 and Alvand components were significantly decreased and increased from their pure planting respectively. The number of spikes per square meter had the highest correlation with yield among the evaluated parameters. The competition models of reverse productivity for Alvand and MV-17 in pure planting analyzed using cayera equation and in intercopping were shenozoki and cayera equations. The reverse productivity of single plant in pure planting system of both cultivars had to linear relationship. The productivity of Alvand single plant was equal with 1.21974 of MV-17 and the single plant productivity of MV-17 was equal 0.8732 of Alvand. The intracultivar competition in Alvand was more than inter cultivar competition, while in MV-17 cultivar was vice versa. The differences between inverse productivity of single plant of Alvand in pure cultivation and intercropping was very low. But in MV-17 this difference was relatively high, which showes that Alvand cultivar is more competitive than MV-17.
