Studies on the Effect of Manganese on the Nitrogen Fractions in Gingelly (Sesamum indicum L.)

Abstract

Biochemical changes due to Mn application were recorded at three stages of crop growth. Lower concentration of 2 ppm was more favourable for increasing the total nitrogen and protein contents. No relationship could be established between soluble nitrogen and Mn, but the non-protein nitrogen increased at 2 ppm and thereafter fluctuations were noted. The higher concentrations of Mn increased the ammoniacal and nitrate nitrogen,
