Abstract

In our study, we aimed to produce a plant biostimulant using sago bagasse, an abundant by- product of sago industry. One step enzymatic hydrolysis was carried out to produce sago bagasse hydrolysate (SBH) by amylase. The concentration of sugar in the SBH was much higher as compared to the native SB. Further, plant bio stimulating efficiency of SBH was investigated through germination study using six different field crops. Among the various concentrations of SBH, significant improvements in the shoot and root length were observed at 1.5% of SBH treated seedlings compared to the control. Similarly, all the tested field crops at SBH 1.5% registered increased biomass, IAA and lipid accumulation compared to the other treatments. Biostimulating efficiency of SBH might be brought by the presence of various sugars in the SBH. Hence, based on these findings it can be concluding that, SBH has the potential to enhance plant growth of various agricultural crops.
