Abstract: A field experiment entitled “Response of rice (Oryza sativa L.) varieties to different planting dates” was conducted at Research Farm, Guru Kashi University, Talwandi Sabo during Kharif season 2017. The experiment comprised of different transplanting dates (27^th June, 11^th July, 26^th July) and three cultivars (PR-126, PR-124, PR-114) making three replications in split plot design with nine treatments. The soil of the experimental field was loamy sand, with neutral in reaction, low in organic carbon and available nitrogen, medium in available phosphorous and high in available potassium. Among the varieties (viz., PR-126, PR-124, PR-114), the variety PR-124 resulted in maximum growth parameters, yield attributes and grain yield (83.13 q/ha) and minimum (78.71 q/ha) from PR-126. The first date of planting (27^th June) gave maximum growth parameters, yield attributes and grain yield (89.97 q/ha) and minimum growth parameters, yield attributes and grain yield (70.06 q/ha) were recorded in third date of sowing (26^th July). Thus, variety PR-124 of rice grown on 27^th June was suitable to obtain the better grain yield.
