Effect of Biofertilizers on Different Parameters of Ground Nut Varieties Arachis Hypogaea (L.)

Abstract

Chemical fertilizers applications to agricultural fields reduce the microbial composition in the fields, which results in decreased agronomic properties of the fields. To overcome this issue, researchers focused on the alternative and cost effective sources for this problem. Utilization of potent microbial inoculants for crop improvement gave unacceptable results in most studies; this necessitates looking for locally isolated and suitable inoculants. Therefore, this study was designed in eleven groups (T1-T11) to evaluate the efficiency of selected microbial inoculants, single or mixed cultures, on groundnut, Arachis hypogea L. Thus, using Rhizobium, Azetobacter, Azospirillium, AMF, and phosphobacteria inoculants at planting improves yields in many morphological and biochemical parameters of leguminous crops. Moreover, mixed inoculants showed improved root and shoot length, which resulted in increased root nodules for improved nitrogen fixation and productivity. Mixed culture improved biochemical parameters such as chl. a & b, Carotenoids, sugars (reducing & non-reducing) and proteins (amino acids) indicated the improved plant growth with significant changes in the plant productivity than compared to the control and single culture groups.
