Abstract

                                The research study detailing the effect of the recommended dose offertilizers supplied along with humic acid at varied levels on the growth offodder maize (African Tall) and fodder cowpea (CO 9) based intercropping wascarried out at Agricultural College and Research Institute, Killikulam duringsummer season (March-May) of 2021. The experiments contains contain12 treatment combinations laid down with Randomized Block Design (RBD)having three replications. Experimental results concluded that the applicationof 125% RDF along with enriched farmyard manure and humic acid @ 20kg ha-1 and foliar spray of 1.0% Urea + 0.5% CaCl2 (T8) under fodder maizeand fodder cowpea intercropping recorded more plant height (237.4 & 181.4cm), number of leaves per plant in fodder maize (16.3), branches per plant infodder cowpea (23.3), dry matter production (71.4 & 47.06 g/plant) at harveststage which was followed by application of 100% RDF along with enrichedFYM and HA @ 20 kg ha-1 and foliar spray of 1.0% Urea + 0.5% CaCl2 (T7) whencompared with control treatments (T12).
