Bio-Priming with Compatible Rhizospheric Microbes Enhances Growth and Micronutrient Uptake of Red Cabbage

Red cabbage is known as the millennium’s functional food, which has a lot of importance in our diet because health-promoting ingredients present it. The current study investigated synergistic relationship rhizospheric-competent microbial agents (Trichoderma harzianum, Pseudomonas fluorescens, and Bacillus subtilis) modulating performance red under field conditions Middle Gangetic Plains, India. Growth parameters were studied at three developmental stages, viz., pre-cupping, early head formation, maturity. Our results suggested that dual application T. harzianum + P. fluorescens along with 75% recommended dose fertilizers (RDF) increased number leaves (24.6), leaf area (537.2 cm2), root length (19.8 cm), micronutrient uptake (Fe, Mn, Cu) by crop, whereas co-inoculation B. subtilis RDF enhanced plant spread (39.0 earliness (95.2 days), Zn uptake. Maximum height (28.7 cm) chlorophyll (SPAD, 77.3) recorded 100% (120:60:60 kg ha−1) combination RDF, respectively. Interestingly, consortium (T. fluorescens) bio-primed plants about 14% higher comparison to receiving sole fertilizers. regression analysis revealed significant Fe Mn (SPAD) between crop. indicated seedling bio-priming efficient bio-agents viable strategy lessen dependence on chemical for improving production.
