Abstract: Wheat (Triticum aestivum L.) is the main staple food of Pakistan. Our soils are phosphorus deficit. To study the effect of different levels of phosphorus on growth, yield and quality of wheat. Experiment was conducted at research area of College of Agriculture, University of Sargodha, Pakistan. The trial was laid out in randomized complete block design with three replications. Five phosphorus rates (0, 30, 60, 90 and 120 kg ha-1) were used. The data collected were analyzed statistically using Fishers analysis of variance technique. Results indicated that phosphorus level of 90 kg ha-1 produced the maximum plant height (84.34 cm), number of tillers m-2 (340.78), spike length (11.33 cm), number of grains per spike (72.54), 1000-grain weight (36.45 g), grain yield (3955 kg ha-1), biological yield (6554 kg ha-1), harvest index (60.30%), crude protein (12.22%.) and fat contents (2.55%). From these results it was concluded that phosphorus level of 90 kg ha-1 is best for maximizing productivity and quality of wheat crop under the climatic conditions of Sargodha, Pakistan.
