Abstract: A pot experiment was conducted in net house of the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during kharif 2014 and rabi 2014-15 to evaluate the direct effect of zinc (Zn) and boron (B) fertilizers on plant growth parameters of rice and their residual effect on subsequent wheat crop grown in red and alluvial soils. Four levels of Zn equivalent to 0, 1, 2 and 4 mg kg-1 soil and four levels of B equivalent to 0, 0.5, 1 and 2 mg kg-1 soil were applied in combinations as treatments in a factorial completely randomized design (FCRD) with three replications. The result showed that among the levels of zinc the direct application of 4 mg Zn kg-1 soil along with RDF to rice was most beneficial and brought highest improvement in growth parameters and similarly on succeeding wheat crop also in both the soils. Among the levels of boron the direct application of 1 mg B kg-1 soil along with RDF recorded highest improvement in growth parameters of rice and 2 mg B kg-1 soil in succeeding wheat crop. However the combined application of Zn and B was found non-significant of rice and succeeding wheat crops in red and alluvial soils of the study area.
