Water shortages and harmful effects of excessive fertilizer use are present in cotton production areas. This study was carried out in three replications in greenhouse conditions according to split plots in randomized parcels to examine some growth parameters (plant height, number of leaf, amount of chlorophyll, fresh weight and dry weight) of different phosphorus doses in cotton under full and restricted irrigation conditions. Flash cultivar of Gossypium hirsutum L. species was used as plant material. Phosphorus dose of 16, 24, 32 and 40 mg kg-1 was applied to the plants under 100%, 66% and 33% irrigation conditions. As a result, irrigation levels had a statistically significant effect on all parameters, whereas phosphorus doses had a statistically significant effect on all parameters except amount of chlorophyll. In terms of irrigation, it was determined that 33% water shortage did not cause significant decreases in plant height, number of leaves, chlorophyll amount, dry weight. In addition, it has been determined that irrigation levels are effective in phosphorus uptake and, water shortage conditions decrease the fresh and dry weights of cotton after P24 phosphorus level, and full irrigation conditions tend to increase these properties, albeit slightly
