Influence of effective microorganisms on Root-shoot ratio and harvest index of groundnut (Arachis hypogaea L.)

Abstract

Effective microorganisms (EM) solution was used in combination with different rates of cattle manure to study feasibility of EM in groundnut cultivation. This study determined the fraction of biomass partitioned to root vs. shoot in groundnut response to cattle manure and EM application. Significant reduction in root- shoot ratio was noted with manure application. Further, it was observed that EM application significantly improved harvest index (HI) of the crop. It suggests that cattle manure at the rate of 15 t/ha with EM would give better plant performance of groundnut.
