Abstract:

In a laboratory study, coarse and fine rice seeds were osmoprimed in fertilizer-based solutions. Priming was done in 5% aerated solution each of urea, nitrophos, DAP and SOP for 48 h. In fine rice, complete failure of germination and emergence was noted in seeds subjected to urea-based osmopriming. Electrical conductivity of seed leachates was also increased by all the seed treatments. In coarse rice, along with urea, nitrophos-based osmopriming treatments resulted in complete failure of germination and emergence. Urea and nitrophos-based osmopriming treatments also resulted in higher electrical conductivity of seed leachates than other treatments including. In both rice types, fertilizer-based osmopriming treatments resulted in lowering the germination and seedling growth.
