Groundnut (Arachis hypogaea L.) most versatile legume and an important oilseed crop in the tropics and semi-arid tropics and its estimated annual production in India is around 6.0 million tones which contributes nearly 30% of the domestic edible oil production. Yield and quality of oil in groundnut is sizeable dependent on proper application of different nutrients that have a direct say on yield traits. Low productivity of groundnut in Karnataka could be attributed to several production constraints, which include poor or imbalanced nutrition and constant exposure to both biotic and abiotic stress factors. Therefore, it is most essential to pay a great attention towards the nutrition of groundnut to enhance its productivity. In this regard an experiment was conducted at Zonal Agricultural and Horticultural Research Station, Hiriyur, Chitradurga district, during Kharif 2015-16. Experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications and 7 treatments to understand the efficacy of antibiotic 2,4-diacetylphloroglucinol (DAPG), produced by some strains of Pseudomonas spp., which may be involved in suppression of several fungal root pathogens and play a beneficial role in plant growth and development along with bio-control activities. The results revealed that majority of the cultures inoculated resulted in enhancement yield attributing traits compare to control. DAPG-1 significantly enhanced the pod yield of 25% over control and DAPG-2 were on par with DAPG-1 (2587 kg/ha pod yield). There were 10 and 15% increase in pod yield of FP-86 and FP- 98 respectively as compared to control. Incidence of root rot was also recorded at 60 and 120 days periodically, After 60 days of sowing, significant differences were observed in the incidence among the treatments. The disease incidence in the treatments was below 6% (FP-98 and DAPG-1 & 2) as compared to control 8.4%. DAPG 2 recorded the lowest incidence (4.6 %). After 120 days fewer incidences was recorded in DAPG-2 (8.1%) as compared to control.
