Abstract
Spinach (Spinacia oleracea) is a perennial vine food in the tropics where it is
widely used as a leafy vegetable. There has been inadequate information on organic
spinach production with the use of cattle and poultry manure thus the luck of suitable
organic fertilizer that could complement or supplement inorganic fertilizer. The objective
of this research was to evaluate the use of cattle and poultry manure in the production
of spinach. The experiment was set up in a randomized complete block design with three
treatments (triple super phosphate (TSP), poultry and cattle manure) replicated three times.
Data on number of leaves per plant, leaf fresh weight, length and width of fist leaf at 4-5 weeks
after planting. Data was subjected to analysis of variance (ANOVA). The key findings of
study revealed that poultry and cow manure had no significance difference in their influence
on plant growth. However, there was a significance difference in the weeks after application
with poultry manure being the best. The research recommends that farmers need to
supplement or compliment inorganic and organic fertilizers during spinach production.
Further research need to be undertaken so as to come up with the most suitable organic
fertilizer so as to cut cost of spinach production, for high production and high profit in
return.
