Sunnhemp

Seed of sunnhemp (Crotalaria juncea) is produced on the Bos Khnor Station (Chamcarleu district, Kampong Cham province). Sunnhemp is sown in association with others cover/relay crops as millet, sorghum, finger millet (Eleusine coracana) among others. As a legume, the sunnhemp develops a mutualistic relationship with rhizobacteria. This specie is also useful to decrease the abundance of plant-parasitic nematode and to decompact the soil through a strong and deep tap root system.

Millet and Sorghum

Millet (Pennisetum typhoides) and sorghum are used as relay crops before or after main upland crops (i.e., maize, soybean, rice). They bring a range of beneficial functions and contribute to the improvement of the soil fertility. Both species produce high amount of biomass and have strong ability to recycle high amount of potassium. This nutrient will be brought back into the soil during the decomposition and mineralization process.
