Abstract

Experiments were conducted in the field and laboratory during the 2011 wet and dry seasons to investigate the effect of hydro-priming and drying duration on the germination, emergence and growth of seedlings of upland rice. Treatments consisted of four hydro-primed durations of 12, 24, 36 and 48 hrs at two and four hours of drying and unprimed (control) laid out in a completely randomized design (CRD) replicated three times. Results show that there was significant effect (P<0.05) of hydro priming on all the growth parameters except the plant height at 1, 2 and 3 weeks after sowing. It was therefore concluded that upland rice variety, NERICA 2 can successfully be hydro-primed for 12 hrs in order to obtain greater establishment and growth performance under Sokoto conditions. Hydrated seeds can be re-dried for four hours without loss of physiological advancement obtained from hydration phase.
