EFFECT OF EXCHANGEABLE MAGNESIUM SYPPLY OF SOD-PODZOLIC LIGHT LOAMY SOIL ON THE pea’s GRAIN YIELD

Abstract

The optimal range of exchangeable Mg content (125-150 mg/kg) in sod-podzolic light loamy soil for the high yield or pea’s grain had been found in the field experiments. The equivalent ratio of Ca: Mg should be around 5 and ratio K: Mg - around 0.6. Sufficient grain yield response up to 0.68-0.96 t/ha to foliar application of magnesium sulphate solution verified the deficit of Mg nutrition for pea plants at Mg content 46-92 mg/kg of soil.
