EFFECTS OF ORGANIC FERTILIZERS ON GROWTH AND YIELD ...

CHAPTER THREE
MATERIALS AND METHOD
3.0 Experimental location
The experiment was conducted at the Fadama end of Organic Skill Demonstration Plot
University of Agriculture, Abeokuta, Ogun state during the 2011 dry season.
3.1 Materials
Mint vines (obtained from FADAMA 2 vegetable growers in Iba Lasu Lagos State.), 15 pieces
of 40cm diameter perforated bowls, topsoil, Tithonia compost from Organic farm and
Organomineral fertilizer from Sunshine Organic Company Akure.
3.2 Methods
Soil and fertilizer analyses were carried out to determine the physical chemical properties Thirty
Core samples soil were taken from 0 -30 cm depth buked together, and representative sample
taken for analysis. Samples of both the Orgarnomineral and tithonia based compost fertilizer
were also analysed. The Mint vines were cut into bits of of 3cm, the pots were filled with 5kg
sieved soil and the fertilizers at the different rates homogenized with it. The mixture was watered
and allowed to stabilize for about a week. The cuttings were then planted into pots (40 cm in
diameter) and watered and growth and yield were monitored for 14 weeks. Fresh herbage yield
and dry weight were determined at the end of the 14 weeks. After the harvest, the fresh herbage
