Abstract:
Soil salinity is one of the most important problems in dry and semi-dry climate areas of the world. So, we investigated the effects of humic acid on visual quality and quantity parameters of native turfgrasses in compared to commercial one under salinity stress to explore can we reduce salinity effects by humic acid or not? So, an experiment was arranged in factorial experiment based on randomized complete design with three replications. The first factor was three grasses consist of two native accessions of Lolium perenne ҅Chadeganʼ and ҅Yarandʼ and its commercial variety, the second factor was four concentrations of humic acid (HA) (0, 5, 10, 15 g kg-1) and the third factor consisted of three levels of salinity (0, 150, 300 mM). Results of analysis of variance indicated that the interaction effects of cultivar × HA was significant in all traits (P
