Nitrogen stress in chickpea (Cicer arietinum L.) as affected by Rhizobium inoculation, Zn, and Mo applications

Abstract

Summary Studies on the effect of Rhizobium inoculation, Zn levels at the rate of 0, 2, and 4 ppm and Mo at the rate of 0, 1, and 2 ppm on N stress in chickpea revealed that SNA and SNC (N stress based on leaf area and crop growth rate, respectively) was zero in 4 ppm Zn + 2 ppm Mo + Rhizobium inoculation treatment at 0–45 d and in 2 ppm Zn + 2 ppm Mo + Rhizobium inoculation at 45 to 67 d and 67–90 d of plant growth. Application of Zn and Mo depressed SNA and SNC values. Molybdenum depressed SNA and SNC more effectively when combined with Rhizobium inoculation.
