Abstract
The up-scaling production of oligochitosan using a continuous gamma irradiation facility at Nuclear Malaysia has been established. Over 2 000 L of 20 000 ppm of oligochitosan at molecular weight of ≤ 10 000 D can be produced per cycle. Subsequently, the oligochitosan has been used in field trials at two different rice plantations during the wet and dry seasons. Both field trials showed remarkable effects on the growth of rice seedlings as well as rice yields. The use of oligochitosan has proven to shorten the period of the rice seedlings from 15 days to 10−12 days. In addition, the cost of this procedure has been greatly reduced since no additional nutrients were used. The growth of the rice seedlings increased by 22.8−23.3% on burned rice husk substrate and by 13.0% on commercial soil when sprayed with oligochitosan as compared to those sprayed with commercial nutrients. With the introduction of oligochitosan, the yield of rice also increased from 2.0-20.0%, depending on the seasons. (author)
