چکیده
Abstract The present study aimed to evaluate the effects of different planting and irrigation management strategies on growth, yield water productivity in rice. experiment was arranged as a split-plot randomized complete block design with three replications. experimental treatments included main plot assigned methods (transplanting at puddled bed [TPB], transplanting non-puddled [TNPB], direct-seeded rice [DSR]) sub-plot systems (continuous flooding (CFI), alternate wetting drying [AWD], drip [DI]). results showed that plants TPB produced highest (3,962.7 kg·ha–1), whereas reduced by 20% 27.2% TNPB DSR, respectively. DSR practice resulted total input (TWI) (8,682.4 m3·ha–1), treatment allowed 17.3% depletion TWI 39.3% enhancment compared DSR. grown under CFI AWD indicated 8.9% 7.6% higher DI-treated plants, DI system water-saving capacity CFI. Our highlight combined application method has great potential reduce without negatively affecting yield.
