Abstract:
The field experiment was carried out to investigate the “Effect of Organic Manures and Iron Application on Soil Properties, Nutrient Availability and Yield of Wheat (Triticum aestivum L.) Under Alkali Water irrigation” was carried out to assess the impact of different alkali water, organic manures and iron on soil properties (ECe, pHs, OC, ESP, CEC) and productivity of wheat. The experiment was set up in a split-plot design with three levels of alkali water (RSC mmol L^-1), (2.0, 6 and 10 mmol L^-1), organic manures (control (M₀), FYM@ 15 t ha^-1(M₁), and vermicompost @ 5 t ha^-1 (M₂) in the main plot and four levels of iron (control, 50, 100, and 150 kg FeSO₄.7H₂O ha^-1) in the sub-plot. The findings revealed that as alkali water irrigation levels increased, the ECe, OC, available N, P, and K, content of soil after harvest of crop, grain and stover yield decreased significantly, while pHs and ESP increased significantly. The use of FYM @15 t ha^-1 and vermicompost @ 5 t ha^-1 resulted in a significant decrease in soil pHs and ESP, while CEC, OC, available N, P and K content of soil, grain and stover yield increased significantly. The grain and stover yield increased significantly with increasing levels of iron.
