PERFORMANCE OF ONION (ALLIUM CEPA LINN) AS INFLUENCE BY NPK AND RABBIT DROPPINGS IN OGBOMOSO, OYO STATE, NIGERIA.
Abstract
The pot experiment was carried out at Crop production and soil science department Arable
Experimental Plot, Ladoke Akintola University of Technology, Ogbomoso, to assess the
performance of onion (Allium cepa linn) as influence by NPK and Rabbit droppings in
Ogbomosho Oyo state, Nigeria . The six (6) treatments introduced were, T0 = (Zero
application of fertilizer), T1 = (100% NPK) application, T2 = (75% NPK + 25% Rabbit
droppings) application, T3 = (50%NPK +50%Rabbit droppings) application, T4 =
(25%NPK +75% Rabbit droppings) application, T5 = (100%Rabbit droppings) application.
The trials were arranged in a Completely Randomized Design (CRD), replicated three
times. All fertilizer treatments were applied at recommended rate. All data collected on
growth and yield parameters were analyzed following the procedures of Analysis of
Variance (ANOVA) and Duncan Multiple Range Test (DMRT) was used to separate
treatment means, at 5% probability level. Soil sample was slightly acidic with pH value of
6.12. T2 (75%NPK +25% Rabbit droppings) significantly enhanced the harvested Onion,
while T0 (Zero application of fertilizer) had the least value across all the parameters
measured. Therefore T2 (75%NPK +25% Rabbit droppings) is recommended to improve
growth and yield of Onion (Allium cepa) and also boost the physical and chemical
properties of soil in the study area.
