Implication

Factorial experimental study demonstrates that microbial co-inoculation enhances nutrient uptake in Marandu grass, indicating potential to reduce chemical fertilizer use.

Key Points

To assess how mineral fertilizer doses combined with Bacillus subtilis and Trichoderma asperellum co-inoculation affect plant growth and nutrient use efficiency in Urochloa brizantha cv. Marandu.
Conducted a completely randomized 3 × 5 factorial experiment with five replications testing three inoculation conditions (uninoculated control, B. subtilis UFRA-92 alone, and co-inoculation of B. subtilis with four T. asperellum strains).
Tested inoculants across five omission levels (0%, 25%, 50%, 75%, and 100%) for nitrogen, phosphorus, and potassium, measuring biometric traits, nutrient content, and nutrient use efficiency.
Co-inoculation combined with 75% nitrogen, 50% phosphorus, and 50% potassium raised leaf nutrient concentrations by 256% for N, 280% for P, and 29% for K compared to uninoculated controls.
Agronomic efficiency increased significantly under co-inoculation at reduced fertilizer levels, showing gains of 462% for N, 544% for P, and 177% for K over controls.
