Micronutrient content and yield of spinach (Spinacea oleracea. L.) as influenced by different sources and levels of iodine fertilization

A pot experiment was undertaken to study of the effect of different sources (Iodine & Iodates) the levels (0.0. 1.0 .2.5 & 5.0 mg kg-1,) of iodine in combination of recommended dose of NPK and NPK + FYM on yield and micronutrient content in spinach (spinacea oleracea. L.)Yield of spinach leaf significantly influenced by various sources and levels of applied iodine at both statges of harvesting (45 and 60 Days after Sowing). Spinach yield was significantly higher with the application of recommended dose NPK +FYM as Compared with recommended dose of NPK alone at each levels of applied iodine Nutrients contents (Fe, Mn, Zn, & Cu).
