Abstract
Bio-nutritional effects of Chromolaena odorata
leaf extracts and fungicide on soil and growth parameters of Telfaira
occidentalis was carried out at the Department of Plant Science and
Biotechnology demonstration site beside the screen house at the Faculty of
Science, Rivers State University. Three concentration (5mgl-1, 10
mgl-1 and 15 mgl-1) levels of C. odorata leaf
extract and fungicide, and C. odorata extract+fungicide
served as the treatments. Soil was treated 3 days before planting and 14 days
after planting for 8 weeks. Physicochemical properties of T. occidentalis soil
were determined before planting and 8 weeks after treatments. Growth parameters
of T. occidentalis were determined in centimeters by measuring the plant
height, leaf length, leaf area where the number of nodes was counted. One-way
t-test analysis was used to determine the impact of treatments on the diseases
of T. occidentalis. Means were separated using Duncan multiple range
tests at 5% probability level. C. odorata+fungicide had higher impact on
potassium (8.475mg/kg) than C. odorata (6.300mg/kg) and fungicide
(6.350mg/kg). C. odorata higher impact on phosphorus (0.851mg/kg) than
fungicide (0.844mg/kg) and C. odorata+fungicide (0.819mg/kg). Fungicide
had higher impact on nitrogen (5.036mg/kg) than C. odorata+fungicide
(3.035mg/kg) and C. odorata (0.367mg/kg) as compared to the control. The
treatments generally had significant positive impact on growth parameter of T.
occidentalis at the various levels of concentration when compared to the
control. However, C. odorata extract had better bio-nutritional
effect on growth parameters (plant height and leaf area) of T. occidentalis even
at 5ml (49.93±15.72 & 64.00±56.47) than fungicide (29.66±21.12 &
43.66±30.72). C. odorata extract possesses bio-nutritional
potential and should be used as biofertilizer for cultivation of crops.
