The present study was aimed to assess the effect of Fe and Zn enriched organics on growth, yield attributes and yield of cowpea crop. A field experiment was carried at the Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the effect of iron and zinc enriched organics on growth, yield and yield attributes of cowpea (Vigna unguiculata L.) in loamy sand during kharif season of 2019. The field trial was laid out with three replications and the treatments comprised of T1 (Control), T2 (5.0 t FYM ha-1), T3 (2.0 t vermicompost ha-1), T4 (2.0 kg Zn ha-1), T5 (3.0 kg Fe ha-1 ), T6 (2.5 t FYM ha-1 + 1.0 t vermicompost ha-1 ), T7 (2.5 t FYM ha-1 + 2.0 kg Zn and 3.0 kg Fe ha-1), T8 (1.0 t vermicompost ha-1 + 2.0 kg Zn and 3.0 kg Fe ha-1), T9 (0.5 t FYM ha-1 enriched with 2.0 kg Zn and 3.0 kg Fe ha-1), T10 (0.2 t vermicompost ha-1 enriched with 2.0 kg Zn and 3.0 kg Fe ha-1), T11 (0.5 t FYM ha-1 enriched with 1.0 kg Zn and 1.5 kg Fe ha-1), T12 (0.2 t vermicompost ha-1 enriched with 1.0 kg Zn and 1.5 kg Fe ha-1). The results revealed that an application of vermicompost @ 0.2 t ha-1 enriched with 2.00 kg Zn and 3.00 kg Fe in conjunction with recommended dose of fertilizer (RDF) significantly improved growth and yield attributes viz. plant height, number of branches per plant, number of nodules per plant, fresh and dry weight of nodules per plant, number of pods per plant, number of seed per pods, seed and stover yield of cowpea as compared to control (RDF).
