ABSTRACT: Cultivating
traditional upland rice cultivars on nutrient depleted soil causes poor and low
yield. Little attention is paid to performance of inter-specific NERICA
cultivars grown on nutrient deficient soil augmented with different types of
compost. Therefore, field trials were conducted during 2010 and 2011 planting
seasons in Ibadan to evaluate growth, dry matter, nutrient uptake efficiency
and grain yield of upland rice grown on nutrient deficient soil augmented with
different types of compost. There were nine treatments comprising of three
upland rice cultivars: NERICA I, NERICA II and Ofada, two compost types applied
at the rate of 8 t·ha-1: poultry dropping + maize stover (PDMC) and cattle dung + maize stover
(CDMC) and control. The treatments were laid out in randomized complete block
design and replicated three times. CDMC enhanced growth, nutrient use
efficiency, dry matter and grain yield of upland rice cultivars. Performance of
Ofada was better than NERICA cultivars. N (24.55 g), P (12.45 g) and K (35.41 g)
uptake concentration and grain yield (5.45 t/ha)
were highest in Ofada plots augmented with CDMC. Residual effect of compost on growth, yield and nutrient uptake efficiency of upland rice on nutrient
deficient soil was marginal.
