Effect of Different Nitrogen Fertilizers on Leaf Micronutrients in Apple (Malus domestica Borkh)

Aims: To evaluate the effect of different nitrogen sources on leaf micronutrients apple in pot culture studies and field studies.
 Study Design: The experiment was laid out a Completely Randomized Design factorial Block Place Duration Study: carried at experimental farm Department Soil Science Water Management, Dr. Y. S. Parmar University Horticulture Forestry, Nauni, Solan (H.P.) Krishi Vigyan Kendra, Rohru, Shimla Horticultural Research Station, Seobagh, Kullu 2016 2017.
 Methodology: Experiments were comprised fourteen treatments each treatment replicated three times, having one plant under replication. Calculated amount fertilizers added soil appropriate time samples collected for determination micronutrients. Copper (Cu), iron (Fe), manganese (Mn), zinc (Zn) contents determined by using atomic absorption spectrophotometer boron (B) estimated Azomethine- H method.
 Results: In studies, Cu 14.96 15.05 ppm, Fe 188.71 194.48 Zn 31.52 32.51 ppm 64.83 65.09 2017, respectively. highest B content recorded urea alone application (35.64 35.48 respectively).
