The present study was conducted at the Rajmata Vijyaraje Scindia Krishi Vishwavidhyalaya Krishi Vigyan Kendra, Farm Science Centre, Rajgarh M.P. During 2019-20 & 2020-21 under institutional research project. The experiment was laid out in randomized block design (RBD). Sixty uniform and healthy tree of mandarin (Citrus reticulata Blanco) planted at 6X6 m distance were selected under the experiment. The experiment consisted of 10 treatment combination of micro nutrients with control. Plants were subjected to foliar spray. The spray was applied twice: once at pea stage and gravel stage. The results of the experiment indicate that the foliar application individual and combination of micronutrients the maximum fruit weight (147.67 g.), fruit yield (71.16 kg/plant) and fruit retention (47.40%) was recorded with the spray of T₁₀ ZnSO₄ (0.4%) + CuSO₄ (0.4%) + MgSO₄ (2.0%) + MnSO₄ (0.5%) + Boron (0.1%) over control with application hence the combination of recommended dose of fertilizers i.e. 400:600:400 gm. NPK/Plant.
