Yield and quality of pea’s grain in relation to the mineral nutrition by magnesium and sulfur on podzoluvisol loamy soils

Abstract

In a stationary field experiment four levels of exchangeable magnesium content were prepared, reflecting the differences in arable soils of Belarus (Mg 45–240 mg/kg of soil). The optimal range of exchangeable Mg 120–140 mg/kg of soil was found for the formation of a high yield of peas with good grain quality. The equivalent ratio of cations in the soil should be Ca2+: Mg2+ = 4–5 and K+: Mg2+ = 0,6–0,7. It was found the positive yield response to sulfur applied to soil and to foliar application of magnesium sulphate solution, that verified the deficit of S and Mg nutrition for pea plants at the range of exchangeable Mg content <120 mg/kg of soil. The parameters of soil and plant diagnostics of pea nutrition with sulfur and magnesium have been developed.
