Abstract:

Imminent water crisis, labour scarcity and climate change threaten the sustainability and profitability of traditional transplanted rice. Direct-seeded rice (DSR) technology has been proposed to reduce water requirement, save labour demand, mitigate greenhouse gas emission and improve environmental sustainability. It involves three principal methods viz., dry seeding, wet seeding, and water seeding, among which dry DSR is gaining momentum due to relatively high grain yield, less water consumption, reduced labour intensity, facilitating to mechanization during crop establishment, and less greenhouse gases emission. In China, DSR is mainly planted in Jiangsu, Anhui, Zhejiang, Guangdong, Yunnan, Hubei, and Xinjiang provinces. Based on the existing evidence, here we review the progress and constraints of dry direct-seeded rice in China. The major challenges confronting the development of dry DSR in China are poor crop establishment, weed infestation, lodging susceptibility, N₂O emission, weedy rice, yield decline under continuous cropping, and variety breeding; and the strategies which may help in mitigating the constraints to dry DSR. In spite of these constraints, we believe that it is a promising strategy to maintain the sustainability of rice production under future water shortage caused by global climate changes. Nonetheless, before the wide adoption of this technology, all the above constraints should be resolved.
