A field experiment was conducted during Rabi 2017 at KVK K, Hassan to study the effect of soil and foliar application of zinc and boron on growth, yield and micronutrient uptake of chickpea with twelve treatments and replicated thrice using RCBD. Results revealed that significantly higher plant height ,number of branches,  total biomass 1944 (kg ha^-1) and seed yield (1262 Kg ha^-1) was recorded with POP + foliar application of Zn as ZnSO₄ @ 0.5 % + B as Solubor @ 0.2 % (T₁₁) and on par with POP + soil application of ZnSO4  @ 15  kg ha^-1 + Solubor @ 5 kg ha^-1 (T₁₂) and  POP (T₂). Higher zinc (15.14 mg/kg &14.07 mg/kg), boron (18.18 mg/kg& 15.39 mg/kg), copper(15.21 mg/kg &11.18 mg/kg), Manganese (42.43 mg/kg &35.58 mg/kg) and Iron (86.81 &70.89 mg/kg) in seed and haulm recorded in T₁₁ (POP+ foliar spray of Zn as ZnSO₄ @ 0.5 % + B as Solubor @ 0.2 %) and the lowest was found in  control (T₁). Significantly higher uptake of Zinc ,boron ,copper ,manganese and iron was recorded in T₁₁treatment and lowest uptake of nutrient recorded in control..
