Abstract: A pot experiment was conduct to assess the effect of various combination Zn, B and S application on growth and yield of hybrid rice. Treatments consist of T₁, absolute control; T₂, 100% RDF through inorganic source NPK; T₃, 100% RDF + Zn; T₄, 100% RDF + B; T₅, 100% RDF + S; T₆, 100% RDF + Zn + B; T₇, 100% RDF + Zn + S; T₈, 100% RDF + B + S; T₉, 100% RDF + Zn + B + S. Experimental results showed a significant increase in plant height, number of tiller, chlorophyll content, number of panicle, length of panicle, grain per panicle, straw yield, grain yield, harvest index and test weight of rice crop with combine application of Zn + B + S with RDF. Maximum chlorophyll content, plant height and number of tiller of rice were recorded in T₉ (RDF + Zn + B + S). Combination of Zn + B + S along with 100% RDF increased grain yield to the extent of 1.34 times over absolute control (no fertilizers) and 1.17 times over control (100% RDF).
