Litchi is one of the important subtropical fruit crops in the state of Jharkhand, occupying around 3.3 thousand hectare and production is about 16.5 thousand metric tonnes. Considering the importance of plant analysis in fruit crops, the present investigation was carried out in an established orchard (since, 1979) at ICAR Research Complex for Eastern Region, Ranchi Centre to study the nutrient concentration in leaves of Litchi orchard as well as interrelationship between available nutrients present in leaf with crop productivity for developing a sound fertilizer management programme. Collection of leaf samples from established orchard was done during the 2006-07; analysis of leaf samples for secondary nutrients (Ca, Mg and S) in plant (leaf) part was carried out. The concentration of secondary nutrients varied from 0.099 to 0.225, 0.050 to 0.114 and 0.070 to 0.076 percent for Ca, Mg and S, respectively. However, mean leaf nutrient concentration was 0.162, 0.082 and 0.073 percent for Ca, Mg and S, respectively. Highest concentration of Ca, Mg and S was observed for the 4th pair of leaves. Significant negative relationship between yield and concentration were observed in 2nd and 4th pair of leaves.
