摘      要：Nursery practice using microbial inoculants was performed to find out the efficacy of the inoculants on seed germination and seedling growth of sissoo（Dalbergia sissoo Roxb.）.Microbial inoculants or effective microorganisms（EM） are a mixture of many different beneficial microorganisms in a *** seedlings were grown in a mixture of sandy soil and cowdung（3：1） kept in polybags with pouring EM solution at different concentrations（0.1%,0.5%,1%,2%,5% and 10%） before and after a week of sowing the *** germination rate and growth parameters of seedlings were measured,such as,shoot and root length,vigor index,fresh and dry weight of shoot and root and total biomass *** nodulation status influenced by EM was also observed along with the measurement of pigment contents in *** highest germination rate（69%） was observed in 2% EM treatment,followed by 67% and 65% in 1% and 5% *** highest shoot length（33.2 cm） was in 2% EM,whereas highest root length（26.3 cm） was in 1% *** fresh and dry weights from shoot and root,were maximum（4.16 g and 1.57 g;2.12 g and 0.83 g respectively） in 2% EM and were significantly（p ≤ 0.05） different from *** index was highest（4071） in 2% EM,which was significantly（p ≤ 0.05） different from *** dry weight increment was highest in 2% EM treatment,followed by 1% and 5% concentrations of *** number was higher at very low（0.1%） concentration of EM solution but it normally decreased with the increase of EM *** contents of chlorophyll a,chlorophyll b and carotenoid were highest（60.11,17.05 and 42.48 mg·L1respectively） in 2% EM treatment and lowest（39.35,13.55 and 27.29 mg·L-1 respectively） in control ***,low concentration of EM（up to 2%） can be used for getting maximum seed germination rate and seedling development of Dalbergia sissoo Roxb.
