Plant biostimulant applications have been proven to improve plant productivity in the field to meet its genetic potential. Protein hydrolisate is used as a plant biostimulant to increase crops productiviy and yield. Protein hydrolysate from organic waste or by-product is highly potential for plant biostimulant, since it efficiently turns the waste into high value product. Trash fish meal and chicken feather meal have high protein content and are potential as plant biostimulants. The aim of this study was to evaluate the activity of protein hydrolysates from chicken feather meal and trash fish meal on germination and early growth of mung bean (Vigna radiata). Hydrolysis was conducted under high temperature and pressure in acidic condition. Chemical analysis was performed to measure nitrogen content in the two materials. Protein hydrolysates under various concentrations: 5, 10, and 20 ppm were applied to determine their effect on seed germination rate, and fresh weights of root and colleoptile. The result showed that germination increased after 7 hours incubation of protein hydrolysate at 10 ppm from chicken feather meal and trash fish meal. Under chicken feather meal hydrolysate, the germination rate increased 99.5%, from 21.7% at blank solution to 43.3%, while under trash fish meal hydrolysate the germination rate increased 191.7%, from 21.7% at blank solution to 63.3% at the treatment, Activity of chicken feather meal hydrolysate on root and colleoptile growth was higher than that of trash fish meal hydrolysate. The effect of protein hydrolysate on root growth was higher than on coleoptile growth. Protein hydrolysates of chicken feather meal and trash fish meal could improve germination rate and early growth of mung bean thus are highly potential as plant biostimulants.
