ABSTRACT Field experiment was conducted at the Experimental farm, Annamalai University, to study the effect of EM (effective microorganism) inoculated composts on yield and their influence on various nitrogen efficiencies indices in maize. There are ten treatments which treatments which includes – Without fertilizer and organic manure (Control), Recommended dose of fertilizer (RDF), RDF with three levels (12.5, 11.5 and 10.5 t ha-1) of EM inoculated pressmud compost, RDF with three levels (12.5,11.5 and 10.5 t ha-1) of EM inoculated Farm Yard Manure (FYM), RDF with pressmud compost(12.5 t ha-1) and RDF with FYM (12.5 t ha-1 ). The experiment was conducted in randomized block design and replicated thrice with ten treatments. The yield components of maize viz., cob length and number of grains cob-1 were favourably influenced by RDF with 12.5 t ha-1 of EM inoculated pressmud compost. It recorded maximun cob length, number of grains cob-1, grain yield and stover yield. Simalarily, Nitrogen use efficiency (NUE), Agronomic efficiency (AE), Apparent N recovery (ANR) and Internal efficiency (IE) were also found higher in this treatment. Hence application of RDF along with 12.5 t ha-1 of EM inoculated pressmud compost to maize crop can be recommended for the farmers for getting higher yields and better nitrogen utilization in coastal regions of tamil nadu. .
