A field experiment was carried out in kharif season in 2018 and 2019 at Crop research farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P). The present study assessed “Effect of foliar applied micronutrients on growth and production of maize-cowpea intercropping system”. The experiment comprised of fifteen treatments consisting recommended dose of fertilizer of NPK and foliar application of micronutrients at 40 days after sowing. Foliar application of micronutrients along with Recommend dose of fertilizer recorded significantly higher grain yield of sole maize (4.92 t ha^-1 in treatment T₄ (Maize sole crop + Foliar application of Boron 1%) and sole cowpea in treatment T₉ (Cowpea sole crop + Foliar application of Boron 1%) 1.93 t ha^-1 as compared to other treatments. Yield attributes of maize viz., number of cob plant^-1, Number of grains cob^-1, test weight, grain yield were highest with the application of RDF + foliar application of Boron @ 1% (T₄). And Yield attributes of cowpea viz., number of pod^-1, number of grains pod^-1, test weight, grain yield were highest with the application of RDF + foliar application of Boron @ 1% in (T₉) was superior over recommended dose of fertilizers with other micronutrients and control. The treatment T₄ (Maize sole crop + Foliar application of Boron 1%) recorded the highest gross returns, net returns and B:C ratio.
