Regulation effect of seed priming on sowing rate of direct seeding of rice under salt stress.

ABSTRACT: Direct seeding of rice (DSR) is a widely used method for its labor- and cost-saving advantages. However, the global intensification of soil salinization presents a significant challenge to food security. Increasing sowing rates is a common practice to enhance germination under salt stress, although it leads to higher seed costs. Recently, seed priming has emerged as an effective technique to improve seedling emergence under abiotic stress, but the regulation of seed priming treatment on the sowing rate of DSR under saline soil conditions has rarely been reported. Therefore, field experiments were conducted at two salinity levels of 1.5‰ (1.5 g kg^-1) (T2) and 3.0‰ (3 g kg^-1) (T3) and under one non-saline condition (0‰) (T1). The control (P1) consisted of non-primed see
