Phosphorus fertilization for getting higher paddy yields is quite necessary owing to its vital role in crop plant development, so a field experiment was conducted to evaluate the appropriate level of phosphorous fertilizer for rice (Super basmati) at Adaptive Research Farm, Sheikhupura during Kharif 2012, 2013 and 2014. Different levels of phosphorous (34, 45, 68, 90, 102 and 136 kg ha-1) were used as treatments in randomized complete block design (RCBD) with 3 replications. The crop was sown using traditional transplanting method during 1st week of July every year. All other agronomic practices were kept uniform for the entire growth season every year. Data related to agronomic parameters including plant height, number of productive tillers, number of grains per spike, 1000-grain weight and paddy yield was recorded using standard procedures. Results revealed that 90 kg ha-1 phosphorous was the most appropriate dose for getting maximum paddy yield under agro-ecological conditions of Sheikhupura.
