Abstract
Brewery waste water sludge (BWS) is produced as the result of aerobic biological treatment of brewery effluent. Analysis of this waste material revealed that it contained valuable nutrients for plant growth (total %N= 4.2, %P=2.5 K=106.4, and Zn 35.16 ppm), heavy metal content within acceptable range (Pb=0.62, Cd=0.04, Hg=0.22, Ni=34.09 and Co=0.77 ppm) and acceptable load of pathogenic microorganisms (5cfu/g for E coil). The brewery sludge can be directly applied to the soil for the agricultural purposes. The main objective of the present study is to compare the effects of BWS and urea fertilizer on the growth and yield of tomato (Lycopersicon esculentum Mill). BWS was applied at 10, 25, 50, 75 and 100 % ratio with soil and urea fertilizer at 50, 100, 150 and 200 mg/kg of soil. Results showed significance in leave height (17.67±0.58 cm) and shoot length (83.33±1.53 cm) were recorded at 25% ratio of BWS and lowest (No growth) at 75 and 100 % BWS ratio. In addition, 200mg urea /kg of soil recorded the highest shoot length (74.67±1.15cm) and 50 mg of urea /kg of soil lowest (64.67±0.58 cm), more number of tomato fruits (16.33±1.53) were produced at 25% BWS compared with (13.00±1) in 200 mg of urea/kg soil and differed significantly (p<0.05) with the control (7.67±1.53) and among treatments. The smallest (No growth) and highest (85.15±8.77g) weights of fruits recorded per plant at 75 and 100 % BWS and 25% BWS respectively, differed significantly (p<0.05) among treatments and control (65.59±1.38g). The smallest (57.05±2.07g) and highest (65.99±2.13g) weights recorded at 200 and 100 mg urea /kg of soil, respectively, also differed significantly (p<0.05). It was concluded that BWS at 25 % ratio and urea fertilizer at 50-200 mg of urea/kg of soil are sufficient for tomato plants but the former outweighs the latter.
