barley-against-skyThe competition function of different component crops under barley-based interropping system with different geometric arrangements was investigated in sandy-clay loam soil at University of Agriculture, Faisalabad for two consecutive years. The geometric arrangements were comprised 40 cm spaced single row, 60 cm spaced double row strips and 100 cm spaced four row strips, while the intercropping system were barley alone, barley + chickpea, barley+ lentil, barley + berseem, barley + linseed, barley + fennel, barley + garden cress (Haloon) and barley + garlic. The main crop barley was sown with different associated cultures and it appeared to be a dominant cropas indicated by its positive sign of aggressiveity, higher values of relative crowding coefficient and competitive ratio. this concluded that barley utilized the available resources more efficiently than respective intercrops.
