چکیده مقاله:
After application of agrochemicals at 1, 30 DAS and at harvest the total number of fungi, bacteria, actynomycetes, pseudomonas, azatobactor, rhizobium were counted.The result with regard tobacterial population in soybean field were significantly influenced by bioinoculant viz., rhizobium. The bacterial populations were inhibitedby herbicides Alachlor in soybean and fungicides i.e. thiram and mancozeb in soybean. After 30 days of spraying of chemicals thebacterial populations were restored. With regard to rhizobium population, the bioinoculant were significantly influenced thepopulation soybean field. The herbicides and fungicides were significantly decreased bioinoculant population, maximum inhibition was observed in mancozeb treated plot at 30 DAS. The results withregards to pseudomonas, actinomycetes and fungi population were influenced by bioinoculant viz., rhizobium. While population wereinhibited by alachlor, thiram and mancozeb in soybean field. The Pseudomonas, actinomycetes and fungi population were restored after 30 days of spraying. With regard to yield of soybean were significantly influenced by bioinoculant in combination with herbicide and fungicide.
