Enhancement of growth and yield of Arachis hypogeae L. using different biofertilizers

The field experiment was conducted in split design with three replicates in Arunagirimangalam village, Thiruvanamalai District to study the effect of groundnut haulm compost of single and combined inoculation of FYM, different biofertilizers (Azotobacter, Azospirillum, Phosphobacteria, Rhizobium) on growth, photosynthetic pigments, biochemical properties and yield of Arachis hypogeae L. The results of this experiment revealed that groundnut haulm with combined inoculation of biofertilizers significantly increased growth, photosynthetic pigments, biochemical and yield parameters of the test crop. Among various combinations, single inoculums of groundnut haulm performed better than control while groundnut haulm with combined inoculation of Rhizobium found better over single inoculation treatments. In general, it could be concluded that groundnut haulm compost and mixed with Rhizobium may be a good tool to improve the crop yield productivity and quantity and soil health.
