Hi Subhadra. Normally in practice, citrus starts fruiting between 3 to 5 years depending upon seed and Seedlings used for cultivation. As per your sent image - I think, your citrus plant is still under developing stage. Lets check at your end. Apply good amount of Farm Yard manure or Vermicompost along with 19:19:19 complex fertilizers to get good growth. You can also use fertilizer calculater available here on home page of Plantix to get good growth. Also its showing initial stage of Citrus Butterfly , Citrus Leaf Miner and Magnesium Deficiency .
