Summary
Multiple cropping of paddy fields has now been widely adopted in East China, in order to increase annual grain yields. The management practices recommended for these multiple cropped fields include the use of mineral fertilizers in combination with organic manure, to sustain a better soil nutrient balance, the adoption of rice-straw manuring, and use of zero or minimum tillage. This paper presents the results of a series of longterm experiments in multiple cropping and discusses the problems associated with these techniques.
