Pot experiment was conducted at the Botanical
Garden of the Department of Biological Science, Usmanu Danfodiyo University, Sokoto
Nigeria, during the 2013 dry season. The main objective of this research was to
determine the effect of water stress and variety on productivity of rice (Oryza
sativa) at Sokoto. The treatment consisted of water stress at three growth
stages (Tillering, flowering, Grain filling) and unstress (control) and three
rice varieties (FARO 44, NERICA 2 and FARO 15) laid out in a Completely
Randomised Design (CRD) replicated three times. The result indicated that water
stress significantly (P < 0.05) resulted to decreased in plant height,
number of leaves per plant, total biomass, harvest index and grain yield. The
results indicated significant (P < 0.05) differences among genotypes. Faro
44 differed significant from in plant height, number of leaves per plant, total
biomass, harvest index and grain yield. FARO 44 differed significantly from
NERICA 2 and FARO 15 at all the parameters under study. Water is very vital as
far as rice production is concern should be applied at every stage of rice
production. FARO 44 is recommended for the area for higher yield.
