Abstract

Bio-metric observations recorded in the field trial conducted at the Agricultural College and Research Institute. Madurai to study the effect of plant density and mode of nitrogen application on Deccan hybrid maize were subjected to a path coefficient analysis to study the cause and effect of the yield attributes on the grain yield. The three yield attributes viz.. grain number per cob. length of cob and 1000 grain weight exhibited posi tive and highly significant correlation with grain yield. Of these 1000 grain weight had the maximum direct effect while the length of cob. the grain number per cob had their influence on the yield through 1000 grain weight.
