Abstract

The field experiment to study the effects of intercropping on weed control, in the Agricultural Research Station of Lorestan University of 2014-15 and 2015-16 with two plants (legume and cereal: broad leaf vetch and abider cultivar of barley) in 4×5 factorial randomized complete block design with three replications, in two consecutive years in one place was carried out on dry land. In this experiment, two plants (legume and cereal or broad leaf vetch and barley cultivar Abidar) in the form of Additive Series Intercropping system with four levels of weed (weeding, once weeding, double weeding and non-weeding) and complementary components of intercropping in five levels, 40: 100 (vetch: barley), 70: 100, 100: 100, 0: 100 (Sole Cropping of barley) and 100: 0 (Sole Cropping of vetch), to determine the yield and the effect of intercropping on the population, dry weight of weeds (plants per square meter) test to determine dominance in the region's flora and species diversity and ecological index was investigated weed control efficiency of all interactions, yield was better in the second year than the first year and by increasing the number of time weeding (control weed) this have more yield. The lowest number of weeds (in square meters) of first and second year with a mixture of 100: 70 (barley: vetch) was equivalent to 21 and 21. 35, Sole Cropping of barley was the lowest greatest weight weed control (34. 54 g/m² ). The levels mix, combination of 100: 40 and 100: 70 most of the weeds dry weight, respectively (24. 56 and 23. 77 gr/m2). So, at the mentioned levels (intercropping balanced) efficiency of weed control in the second year was than the first year. Also, by reducing the share of vetch from 100 to 70 and 40 percent, the exploitation of the environment reduced and minimum LERt in the second year and different levels of weed was belonged to 40: 100 seed ratio.
