Seasonal variation in micronutrient contents of mulberry (Morus alba) leaves under temperate climatic conditions of Kashmir.

Mulberry, Micronutrients, Season, Phase, Sampling.

Foliar analysis conducted during 1st phase (prior to pruning on May 1, May 15 and June 1) and 2nd phase (after pruning on August 1, August 15, September 1, September 15 and October 1) on eight sampling dates revealed that zinc and copper contents in leaf decreased with advancement of age, while as iron and manganese accumulated in leaves with maturity. During 2nd phase the concentration of Zn, Fe, Cu was comparatively lesser than that of first phase on corresponding sampling dates, contrary was the case with Mn which recorded higher concentrations during 2nd phase, necessitating the augmentation of the deficit during respective phases.
