Study of Magnesium Status in Some Gypsiferous Soils and Response of Wheat Plant (Triticum aestivum L.) to Magnesium Fertilizer 1-Effect on Yield and Yield Components

Abstract

Pot experiment was conducted in greenhouse to study the effect of magnesium fertilizer and soils gypsum content on grain yield and yield components of wheat plant IP99 using CRD design. Mg-fertilizer added at four levels(0,40,80,120 mg.Kg-¹) as magnesium sulfate,While soils gypsum content was (G₁=5%,G₂=15% and G₃=25%). At harvest stage yield and yield components were calculated. The percentage increase in grain yield was as follow 31.94%,51.45% and 32.74 at Mg₁, Mg₂ and Mg₃ respectively compared with control Mg₀ treatment. The highest grain yield 9.91( gm. pot-¹)was at Mg₂G₃ treatment .The high of grain yield was mainly due to the number of grain .ear-¹ and the weight of 100 grain . Highest Mg uptake of Mg in grains was 52.18% mg.Mg(grain). pot-¹ Mg₂G₃ treatment .
