ABSTRACT Small-scale farmers in South-East Asia face serious challenges in agricultural productivity, food security and environmental degradation. Complex Rice Systems (CRS) entail an integrated farming approach that combines new technologies with traditional practices and knowledge to sustainably increase agricultural productivity. A field experiment was conducted to evaluate the potential of CRS by adding rice, fish, ducks and border crops to rice fields in Lima Puluh Kota (West Sumatra, Indonesia) to improve rice productivity and dietary nutrient supply. The treatments were: conventional rice (CON), organic rice (ORR), organic rice with border crops (ORB), organic rice with fish (ORF), organic rice with ducks (ORD), and organic rice with ducks, fish, and border crops (CRS). The experiment resulted in improvements in growth, development and yield of rice in CRS and ORD compared to other treatments. Despite elevated costs, treatments with ducks also resulted in a higher gross margin than the other treatments. CRS produced the most diverse nutritional composition, and higher nutritional value compared to ORD. It was concluded that CRS can contribute to higher rice yields, improved farm income and more diversified diets, and thus providing a comprehensive approach to improve livelihoods and food security of small-scale farmers.

复杂水稻系统对印度尼西亚西苏门答腊小农的潜在经济和营养益处

摘要东南亚的小农在农业生产力、粮食安全和环境退化方面面临严峻挑战。复杂水稻系统 (CRS) 需要一种综合耕作方法，将新技术与传统做法和知识相结合，以可持续地提高农业生产力。进行了田间试验，通过在 Lima Puluh Kota（印度尼西亚西苏门答腊）的稻田中添加水稻、鱼、鸭和边境作物来评估 CRS 的潜力，以提高水稻生产力和膳食营养供应。处理分别为：常规水稻（CON）、有机水稻（ORR）、边缘作物有机水稻（ORB）、鱼有机水稻（ORF）、鸭有机水稻（ORD）和鸭、鱼和有机水稻。边境作物（CRS）。实验导致生长的改善，与其他处理相比，CRS 和 ORD 中水稻的发育和产量。尽管成本增加，鸭子治疗的毛利率也高于其他治疗方法。与 ORD 相比，CRS 生产的营养成分最多样化，营养价值更高。得出的结论是，CRS 有助于提高水稻产量、增加农场收入和实现更多样化的饮食，从而为改善小农的生计和粮食安全提供综合方法。
