The goal of Biologically Integrated Farming Systems (BIFS) in Rice is to demonstrate at the field level alternative rice production strategies that reduce inputs while maintaining high grain yields. The conventional water-seeded system that produces the highest yields in the world requires approximately 150 kg/ha of synthetic nitrogen fertilizer, several pesticide applications, and sophisticated cultural management. Rising input costs, strict pesticide regulations, the imminent ban on rice straw burning, and the implementation of the Food Quality Protection Act prompted researchers and growers to explore alternative farming practices. Alternative management practices used by some growers or those developed based on University of California research may potentially reduce chemical inputs (i.e., production costs) while maintaining high yields. These practices include: straw residue incorporation to conserve N. That also preserves air quality by eliminating straw burning, leguminous winter cover crops as an alternative N source, drill seeding, and water depth management as a means of weed control. Thus, the objective of this project is to demonstrate alternative rice production methods, promote sustainability, and distribute applicable information using a farmer-to-farmer extension model.
