SRI + Conservation Agriculture (CA)
SRI can be combined with different agroecological practices such as Conservation Agriculture, Integrated Pest Management, water harvesting, aquaculture, and organic farming. Choosing the right combination for each farmer's specific needs and context is crucial for creating a sustainable and effective cultivation system.
SRI and CA integration is successful in Pakistan through PQNK (Paradoxical Agriculture), combining organic SRI with permanent no-till, mulched raised beds and furrow irrigation. PQNK increased average yields to 12.84 t/ha in 2009, three times the area norm, with 70% less water application and a 30% reduction of labour.
In China, Sichuan farmers with the Sichuan Academy of Agricultural Sciences developed a CA version of SRI where seedlings are transplanted into raised beds through thin plastic sheets to suppress weeds, while establishing a crop rotation with mustard in the off-season.A large-scale farmer implements a mechanized version of CA+SRI on its farm in Arkansas, US. He also utilizes no-till, mulched permanent raised beds and furrow irrigation, a system that helped increasing the profitability of his rice farming by reducing costs and stabilizing yields.
