Competition of nine wheat (Triticum aestivum) cultivars against Melilotus alba
Abstract
Ranking of crop cultivars competitiveness against the weeds could be an effective strategy in weed management that resulted in increased our knowledge about the crop ability to suppression of weeds. A field experiment was conducted at Qrakhyl Agronomy Research Station, Iran, to evaluate 9 wheat cultivars competitiveness against Melitotus alba. Wheat cultivars including Morvarid, Darya, Nai 60, Milan, N-85-5, N-87-4, N-86-7, N-80-19 and Shanghai planted in both presence and absence of M. alba in split plot design with four replicates. Competition reduced height, tiller number, grain and biological yield of cultivars. Wheat cultivars showed variations in response to competition. Morvarid cultivar was more successful in reducing M. alba biomass. A significant correlation was found between wheat height and weed biomass. Morvarid and Nai60 had the maximum competition index that representing higher ability of the cultivars to inhibit M. alba than other ones. Grain yield of wheat cultivars positively correlated with the ability to withstand competition (AWC). The wheat cultivars revealed variations in tolerance to competition.
