Description The experiment was conducted during 2012-13 at college farm, Department of
Agricultural Microbiology and Bioenergy, and Department of Soil Science & Agricultural
Chemistry, College of Agriculture, Rajendranagar, ANGRAU, Hyderabad.
The field experiment was conducted following randomized block design with 9
treatments and three replications. Treatments consisted of T1 - 100% RDF, T2 - Uninoculated
control, T3 - Only seed coating with inoculant, T4 - Only soil application with
inoculant, T5 - Seed coating + soil application of inoculant with FYM, T6 - Seed coating +
soil application of inoculant with FYM at 25 DAS, T7 - Soil application + soil application
of inoculant with FYM at 25 DAS, T8 - Seed coating + soil application with FYM + soil
application of inoculant with FYM at 25 DAS, T9 - Only soil application at 25 DAS. The
growth parameters viz., plant height, root length, nodule no. plant-1, nodule dry wt. (g plant-
1), dry matter accumulation (g plant-1), were recorded at different crop growth stages.
Likewise observation on yield attributes viz., number of seeds pod-1, weight of 100 Seeds,
seed yield were taken at harvest. The protein % in seed and nutrient uptake were estimated
at harvest stage. Also available soil nitrogen, phosphorus and potassium and microbial
population were recorded at initial, flowering and harvest stage.
At 25 DAS and 50 DAS, treatment T9 (only soil application at 25 DAS) recorded
significantly higher plant height, whereas treatment T8 (seed coating + soil application with
FYM + soil application of inoculant with FYM at 25 DAS) recorded significantly
maximum root length as compared to all other treatments. At flowering stage treatment T8
(seed coating + soil application with FYM + soil application of inoculant with FYM at 25
DAS) recorded significantly higher number of root nodule and nodule dry weight and also
total dry matter production and seed protein content at harvest stage compared to all other
treatments.
Multiple application of microbial inoculants i.e seed treatment + soil application of
inoculants with FYM + at 25 DAS soil application of inoculants with FYM recorded
maximum yield, number of seed per pod-1 and 100 seed weight than all other treatments.
Highest nitrogen, phosphorus and potassium content and uptake, and higher
available nitrogen, phosphorus, potassium in the soil were observed in the treatment
receiving seed treatment + soil application of inoculants with FYM + at 25 DAS soil
application of inoculants with FYM which was significantly higher than the inoculants
applied through only seed treatment or only soil application or seed treatment + soil
application only once. At harvest, treatment T8 (seed coating + soil application with FYM +
soil application of inoculant with FYM at 25 DAS) recorded significantly higher bacterial,
fungal, actinomycetes, Rhizobium and Pseudomonas population as compared to the other
treatments. The significantly lowest bacterial, fungal, actinomycetes, Rhizobium and
Pseudomonas population was found in the treatment T2 (un-inoculated control).
