Methods of planting Crotalaria juncea (sunn hemp) to be used as a green manure plant in areas
with saline soil are as follows:
1 . The period of planting is during February to April whereby planting is conducted in
between after harvesting rice yields so that Crotalaria juncea ( Sunn hemp) can thrive and give out
high biomass.
2. Plough and ferment rice stubble together with using PD 2 bio-extracts to create bacterial
process in the soil accelerating decomposition taking about 2 weeks. Then, sunn hemp is sowed at
the rate of 31.25 kg/ha in the soil with appropriate moisture throughout the plot in order to bring
about regular germination.
3 . Plowing up and over to cover sunn hemp stubble at the age of 120 days after collecting
seeds of sunn hemp whereby the stem of sunn hemp is at the average of more than 1.2 meters
resulting in obtaining more biomass. After that, during the period of preparing the area for planting
rice, rice can be sowed in May or when there is enough amount of water.
