Abstract

An attempt was made to study the effect of different native strains of Azospirillum inoculation on the paddy variety of ADT-36. To find out the best strain in terms of seedling characters such as seed germination, biomass and phytomass yield under controlled conditions. In the case of seed germination, the percentage of seed germination was higher in Azospirillum treated seed than in control. Similarly, shoot and root lengths and fresh and dry weights of paddy variety ADT-36 treated with Azospirillum inoculation showed better response than the untreated plants due to the secretion of plant growth hormones by Azospirillum. The biochemical parameters of total chlorophyll and carotenoid were also increased to varying level in Azospirillum treated plants. The overall studies indicated that the growth of Azospirillum treated paddy seedling excelled over the untreated ones due to biofertilizer effect upon nitrogen fixation. Among the 10 native Azospirillum strains (TNM01, TVM02, TKV03, TNM04, TVR05, TKC06, TMG07, TKR08, TTP09 and TMP10) treated the TMP10 and TNM5 strains showed good response.
