Effect of Phosphorus on Growth, Yield and Mineral Composition of Wheat in Different Textured Saline-sodic Soils
Muhammad Abid, Fayyaz Ahmad , Niaz Ahmad and Iftikhar Ahmad

Abstract:
A pot experiment was conducted to study the effect of phosphorus rates on growth, yield and mineral composition of wheat in a saline-sodic silty clay loam [ECe 5.6 dS m-1; SAR 14.02 (mmol L-1)½] and silt loam [ECe 12.0 dS m-1; SAR 24.02 (mmol L-1)½] soils, respectively. Phosphorus was added @ 0, 50, 100, 150 and 200 kg ha-1, respectively along with a basal dose of 150 and 60 kg ha-1 nitrogen and potassium. The results revealed that growth and yield of wheat increased significantly with P rates over control in both the soils. However, the increase in growth and yield was more with similar levels of P in the case of silty clay loam than that in the silt loam soils. Results also indicated that maximum grain and straw yields were obtained when P was applied @ 100 kg ha-1 in both the soils. Nitrogen and P uptake by straw was recorded maximum at 150 kg P2O5 ha-1. The uptake of K+, Na+ and Cl¯ decreased with P application. It may be concluded that for wheat, phosphorus may be added @ 100 kg ha-1.
