Field experiment was conducted to
evaluate the effect of agro organic wastes against NPK fertilizer on upland
rice performance in Port Harcourt, Rivers State, Nigeria. The experiment was
conducted at the Teaching and Research Farm of the University of Port
Harcourt. The experiment consisted of five (5) treatments namely: 0
(control), 300 kg/ha NPK (15 – 15- 15) Fertilizer, 10 t/ha poultry manure
(poultry droppings), 10 t/ha spent mushroom substrate, 5 t/ha poultry manure
+ 5 t/ha spent mushroom substrate. The treatments were laid out in a
randomized complete block design (RCBD) with four (4) replications. The
study showed that there were no significant differences among the treatments
on growth attributes (plant height and leaf area), yield and yield
components (number of tillers, fresh weight of tillers, dry weight of
tillers, dry weight of panicle, 1000 dry weight of grains and grain yield)
although 5 t/ha poultry manure + 5 t/ha spent mushroom substrate tended to
produce higher growth attributes, yield and yield components compared to
other treatments. The control (where no treatment was added) gave the lowest
growth attributes, yield and yield components. Therefore, the combination of
5 t/ha poultry manure +  5 t/ha spent
mushroom substrate is recommendable to upland rice farmers in the area of
study since they complement each other and served as a better alternative to
NPK (15: 15: 15) fertilizer, which is scarce and expensive.
