Background & Objective: This research was carried out to investigate the growth characteristics, yield components and yield of lentil (Lens culinaris L.) in intercropping with barley.
Materials & Methods: The experiment was conducted in a complete block design with three replications and five treatments at research farm of faculty of agriculture, university of tabriz at 2017. Cropping patterns based on replacement series. Barley was considered the main crop and lentil as a sub-crop. The cropping pattern included: monoculture of barely and lentil and intercropping of these two species with the ratio of 1:1, 3:1 and 5:3.
Results: Plant height, number of tillers, grains per spike, 1000 grains weight, biological yield in barley and plant height, branches per plant and pods per plant in lentil plants were affected by intercropping. In all cropping patterns, the Land equivalent ratio (1:1 1.96, 2:1 1.94, 5:3 1.74), which indicates the relative benefit of intercropping compared to monoculture. The mean of relative crowded coefficient in the different intercropping patterns showed that lentil with a value of 1.054 is a stronger competitor than barley. The relative value for all three patterns of intercropping (1:1 5.44, 2:1 5.38T 5:3 5.30), which indicates the economic benefit of intercropping compared to the monoculture of barley and lentil.
Conclusion: According to the Land Equivalent Ratio and Total Relative Value, the 1:1 intercropping pattern was superior to other patterns and was more beneficial than other intercropping patterns. In this intercropping pattern, the lentil is a stronger competitor more than barley.
