Pamuk üretim alanlarında, su sıkıntısı ve aşırı gübre kullanımının zararlı etkileri söz konusudur. Bu çalışma, 2012 yılında, tam ve kısıntılı sulama koşullarında farklı fosfor dozlarının pamukta bazı gelişim parametrelerini (bitki boyu, yaprak sayısı, klorofil miktarı, yaş ağırlık ve kuru ağırlık) incelemek üzere tesadüf parsellerinde bölünmüş parseller deneme desenine göre sera koşullarında üç tekerrürlü yürütülmüştür. Bitki materyali olarak Gossypium hirsutum L. türüne ait Flash çeşidi kullanılmıştır. Bitkilere tam sulama ile %66 ve %33 su kısıtı koşullarında; 16, 24, 32 ve 40 mg kg-1 dozlarda fosfor uygulanmıştır. Araştırma sonucunda, sulama düzeylerinin tüm parametreler, fosfor dozlarının ise klorofil miktarı hariç incelenen diğer parametreler üzerinde istatistiki önemli olduğu gözlemlenmiştir. Sulama yönünden hafif su kısıtının (% 33) bitki boyu, yaprak sayısı, klorofil miktarı ve kuru ağırlıkta önemli oranda azalışlara neden olmadığı tespit edilmiştir. Ayrıca sulama düzeylerinin fosfor alımında etkili olduğu, su kısıtı koşullarının P24 fosfor düzeyinden sonra pamuğun yaş ve kuru ağırlıklarını azalttığı, tam sulama koşullarının ise bu özellikleri az da olsa artırma eğiliminde olduğu tespit edilmiştir.

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.
