Relationship between P and Mn in chickpea (Cicer arietinum L.)

Summary Phosphorus and Mn relationship was studied in chickpea at two stages of growth in pot culture using 0, 7.5, 15 and 30 ppm P and 0, 5, 10 and 15 ppm Mn. The dry matter yield increased with P at both stages of growth. Manganese improved the yield only in the first stage. Initial levels of Mn enhanced while higher levels had a depressing effect on tissue P. Addition of 7.5 ppm P enhanced Mn concentration at first stage and at higher levels a marked reduction in Mn content was observed at both the stages.
