This experiment was conducted to evaluate of two promising rainfed wheat cultivars as affected by different seeding rate in conventional and conservation tillage systems in the research field of the Dryland Agriculture Research Institute (DARI), Sararood branch, Kermanshah, Iran. The experiment layout designed as strip-split plot in a randomized complete block design with 3 replications during two consecutive growing seasons 2017-18 and 2018-19. The tillage systems were placed next to each other as a separate site at two levels: conventional tillage and conservation tillage (no tillage). Wheat cultivars were performed horizontally at two levels (Baran and Rijaw) and the seeding rate was carried out vertically with eight levels (75, 100, 125, 150, 175, 200,... |
