Abstract
The experiment was conducted during rabi season in medium black soil at College Farm, College of
Agriculture, Rajendranagar, ANGRAU, Hyderabad, Andhra Pradesh to study the influence of biofertilizers,
vermicompost and chemical fertilizers on growth, nodulation, nutrient uptake, seed yield and economics of Black
gram. From the data, it was observed that 50%RDF + Vermicompost + Rhizobium + Pseudomonas significantly
increased the plant height, root length, leaf area index and leaf chlorophyll content at 25 and 50 DAS over the other
treatments including control. The same treatment recorded highest seed yield (707 kg ha-1) and haulm yield (7067
kg ha-1) as compared to the control. Nutrient uptake recorded significantly highest in the treatment supplied with
biofertilizers along with Vermicompost and 50%RDF. Treatment supplied with 50%RDF + Vermicompost +
Rhizobium + Pseudomonas recorded highest net return (17784 Rs ha-1) but highest B: C ratio (2.11) was recorded in
the treatment supplied with 50%RDF + Rhizobium + Pseudomonas.
