Growth Performance And Nutritional Composition Of Phaseolus Vulgaris Grown On Dump Site Soil

ABSTRACT

Two varieties of phaseolus vulgaris (black and brown) were evaluated for their growth performance, proximate composition and antinutrients presence in different percentage of dump site soil (0%, 25%, 50%, 75%, and 100%). Hundred percent (100%) dump site soil was found to give a greater height in black bean (231.00cm) and 7 5% had 226.333cm at the 71 st day after planting in brown bean. Hundred percent (100%) and 75% was found to give high number of pods (20) in black bean while 75% had the highest number of pods in brown beans (21). The proximate composition and antinutritional content in black bean with respect to the soil percentage are: carbohydrate content (mg/g) at 0%=13.5mg/g, at 100% = 17.03 mg/g. Protein content at 0%= 28.82 mg/g, at 100%= 26.83 mg/g, at 75%= 27.53 mg/g, at 50%= 27.53 mg/g and at 25%= 26.72 mg/g. For brown bean, carbohydrate content at 100%= 13.29 mg/g, at 75%= 14.04 mg/g, and at 50%= 18.17 mg/g. Protein content at 0%= 26.83 mg/g, at 100% = 28.81 mg/g, at 75% = 26.95 mg/g and at 50%= 18.17 mg/g. Fat content at 100% = 17.01 mg/g, at 75% = 13.05 mg/g, at 50% = 26.97 mg/g. The antinutritional composition for black bean- tannin content at 0% = 0.39mg/g, at 100% = 0.3mg/g, at 75% = 0.43mg/g and at 50% = 0.35mg/g. Trypsin inhibitor content at 0% = 1.90 mg/g, at 100%== 1.90 mg/g. Phytate content at 0% = 0.34 mg/g, at 100% = 0.41 mg/g, at 75%= 0.38 mg/g. Oxalate content at 100% = 0.23 mg/g, at 0% = 0.21 mg/g. HCN content at 0% = 26.03 mg/g and at 75%= 23.03 mg/g. For brown bean, trypsin inhibitor content at 0% = 2.3lmg/g, at 75% = l.81mg/g. Tannin content at 0% = 0.42 mg/g and at 75% = 0.38 mg/g. Phytate content at 0% = 0.38 mg/g, at 75% = 0.34 mg/g, and at 50% = 0.43 mg/g. Oxalate content at 0%= 0.16 mg/g, at 75% = 0.33 mg/g. HCN content at 0% = 25.0 mg/g, at 75% = 24.02 mg/g, and finally at 50% = 24.01 mg/g. Some plants died off before experiments were carried out.
