Fermented Cassava Processing Effluents as Soil Conditioners Modulate the Growth and Biochemical Compositions of Black Nightshade
Abstract
This experiment investigated the effects of varying levels of cassava processing effluents (25, 50, 75, and 100%) of Lafun effluent (LE), Gari effluent (GE) and Akpu effluent (AE) and distilled water (control) on growth and nutritional compositions of black nightshade. Sodium (128.75mg/100g), calcium (68.15mg/100g), potassium (56.50mg/100g) and magnesium (29.70mg/ 00g) were significantly higher (p<0.05) in GE compared with other levels of effluents. Plant height (48.17cm) was higher (p<0.05) in the black nightshade applied with 25% GE as well as the number of leaves (89.67) in control. Leaf area (228.05cm2), specific leaf area (116.25m2kg-1), leaf area index (16.90m2m-2), relative growth rate (0.214 mg-1day-1), net assimilation rate (0.009 gm-2day-1) and leaf area ratio (0.83 m2kg-1) showed significant increase in the vegetable applied with 100% GE. Also, 75% of AE produced higher fat (0.22%) ash (0.93%), crude fibre (1.83%), crude protein (2.21%) and carbohydrate (1.78%). Niacin (0.99 mg/100g), ascorbic acid(12.81mg/100g) and tocopherol (0.91 mg/100g), as well as sodium (11.89mg/100g), potassium (439.10mg/100g), calcium (45.07 mg/100g), magnesium (41.28 mg/100g) and phosphorus (106.91mg/100g), showed significant increase in the vegetable applied with 75% LE. In conclusion, 25 % GE and control improved morphological parameters while 75 % AE and LE enhanced the physiological and nutritional attributes of the vegetables.
