Schofield. The recommended nutrient dose was N:P:K @ 20:80:30 kgha-1.
The experiment was laid out in Strip Plot Design with four replications.
The study revealed that co – inoculation of Stylosanthes with VAM and Rhizobium significantly increased the plant height. The nutrient dose, 50 percent of the recommended dose and 100 percent of the recommended dose were found to be at par.
A consistent increase in leaf : stem ratio and spread of plants was noticed due to dual inoculation with VAM and Rhizobium
There was significant increase in nodulation and nodule weight on inoculation with VAM + Rhizobium. The highest number of nodules (141.8 in first cut and 211.8 in second cut) was recorded by the dual inoculation treatment.
Significant response to dual inoculation was observed with respect to green matter yield (52% increase over control in the first cut and 34 % increase in the second cut). Similar results were obtained in the case of dry matter yield also.
The treatments 50 percent recommended dose and 100 percent recommended dose were at par for green matter and dry matter yields.
The phosphorus uptake values also showed significant increase with dual inoculation.
The treatment VAM + Rhizobium + 50 percent recommended dose recorded the highest B/C ratio of 2.01.
