    Abstract: In order to investigate response of phonological traits and grain yield of rice genotypes under three cropping systems, an experiment was carried out as split plot in randomized complete blocks design based four replications at Neka, Mazandaran, Iran in 2011 and 2012. Planting systems were chosen as main plots (Conventional, Improved and SRI or System of Rice Intensification) and genotypes as sub plots (Tall plant: Sang Tarom and Hashemi Tarom; Short plant: Neda and Shiroodi).
