Abstract
A field experiment was conducted to study the “Impact of inoculation of different rhizobium strains on growth and yield of groundnut”. The experiment was designed with taking inoculation of different strains of rhizobium. Inoculation with rhizobium had significant impact on plant morphology, yield and yield attributing character over control. The inoculation of Rhizo5(DGR35) produced the maximum plant height/plant (48.1cm), highest number of branches/plant (5.80), numbers of leaves/plant (108.92) at harvest. Higher yield and yield attributing characters that is Hundred kernel weight (37.36 g/ha), Pod/plant (19.8), shelling percentage (73.13%), pod yield (1876 kg/ha), haulm yield (3706 kg/ha), with the harvest index (36.1) recorded in Rhizo5(DGR35) inoculation. Thus, kernel inoculation with Rhizo5(DGR35) recommended for higher productivity and profitability in kharif groundnut.
