The present project was initiated to find out level of various nutrient elements in leaves at various growing stages. It was noticed that leaves of bearing terminals showed less concentrations of nutrients at stage one (0.956% N, 0.057% P, 0.918% Ca) which gradually increased from stage 2nd (0.981% N, 0.062% P, 1.131% Ca) to stage three (1.626% N, 0.182% P, 2.482% Ca) with minor variation in case of K, Mg and Fe. In case of non-bearing terminals, highest level of nutrients was found at stage one (1.589% N, 0.203% P, 0.839% Mg) with a gradual decrease up to stage three (0.902% N, 0.063% P, 0.197% Mg) with minor variation in K and Cu. In Fe, sugars and starch, a reverse pattern was observed. Zn and Mn showed no variation from first to third stage.
