An experiment was conducted in Yewa North Local Government
Area, Ogun State to evaluate the effect of four soil types
(loamy, sand, clay and silt) amended with poultry manure
(PM), plant manure (PLM), sheep/goat manure (SGM) and NPK on
performance of Cochorus olitorius. It was a factorial
experiment in completely randomized design. Pre-treated
seeds were planted and watered daily. Agronomic data
collected on days after planting were plant height, number
of leaves and stem girth. Data were analyzed using
generalized linear model of SAS version 9.1. Means were
separated by least significant difference at P < 0.05.
Results obtained indicated that loamy soil had significantly
higher plant height, number of leaves and stem girth than
other soil types. Silt had the least values for all the
parameters measured. Performance of the soil types were in
the order Loam > Sand > Clay > Silt. PLM had significantly
higher plant height and stem diameter than PM and NPK but
not significantly different from that of SGM. Loamy soil
amended with either PLM or SGM performed better for all the
parameters measured and therefore recommended in this study.
Key words:
Organic manure, plant manure, soil type, Cochorus
olitorius. |
