Abstract: The multiple cropping system on the Haihe Plain serves as an important overall driver of socio-economic development in the region. In this study, several multiple cropping patterns were established with different combinations of cotton and Secale cereale sown on four dates at Ren Town, Hebei Province, during 2011 to 2014. The feasibility of a multiple cropping pattern of cotton/S. cereale was analyzed in terms of yield, economic benefit, water-use efficiency, nutrient-use efficiency, and soil improvement. The results indicated that cotton/S. cereale multiple cropping was feasible. To reduce the influence on cotton yield, the best sowing date for S. cereale is around 20 October in the current year, and its harvest time should be at the end of April in the next year. Under these conditions, the economic benefit increased by 5470.1 yuan·ha-1 according to our research. Compared with monoculture, the multiple cropping pattern improved water-use efficiency and water-economic-use efficiency by 16.49% and 56.54%, respectively. The multiple cropping pattern also improved soil quality; it increased soil organic matter by 5.71%, and decreased soil salinity by 23.72%, compared with monocropping. These results highlighted the importance of multiple cropping for socio-economic development in this region.
