Assessment of effect of Prosopis juliflora litter extract on seed germination and growth of rice

Santosh Kumar Mehar


It has been reported that mesquite (Prosopis juliflora (Sw.) DC.), which is widespread in Saudi Arabia, the United States of America and India, inhibits the germination or growth of many plant species growing in its vicinity, through by releasing allelopathic substances into the environment. Due to this Therefore, it has not been put to good use despite enormous biomass production. The present study was attempted to observed the effect of aqueous extract of mesquite on the growth of rice seedlings. For this To this end, two different concentrations of an aqueous extract (0.1 and 1%) of the aqueous extract was were added as treatments and various parameters of seedling growth like seed germination, root length, shoot length, length and total number of adventitious roots, fresh and dry weight of root and shoot were recorded. We did not eliminate the effect of microbial component in our treatments and during incubation (from lasting 1 day to one week): the phyllosphere microflora had sufficient opportunity to influence the allelopathic outcome after extract addition. The Our results indicated that except for some treatments, both at low concentrations; most of the treatments had led to comparable or better growth of seedlings than did the control treatment. Even when there was less reserve mobilization from seeds during germination; seedlings were able to make up the loss in due course of time and showed better growth than control. Copyright ©
