Effect of Pseudomonas Fluorescens and Humic Acid on Cabbage

Organic input as humic substances significantly increases the nutrients availability and consequently affects growth, yield and quality of crops. The bio-organic substances with chemical fertilizers have overall favourable effects on plant health. Humic acid is particularly used to decrease the negative effects of chemical fertilizers and reduces dependence on chemical fertilizers. Bio-organics have an ability to convert nutritionally important elements from unavailable to available form through biological processes. P. fluorescens stimulates growth and growth contributing characters of cabbage. Plant growth of vegetables like cabbage, cauliflower and tomato influenced well to the use of humic substances and P. fluorescens in minimizing the transplanting shock and encourage quick growth of crops. The combined use of humic acid and Pseudomonas fluorescens is better for vegetative growth, maximization of yield and improvement in quality of cabbage and soil health.
