The Fertilizing Potential Of Breweries Waste Water Sludge Compared To Urea On The Growth And Yield Of Tomato Plant

waste water sludge (BWS) is produced as the result of aerobic biologicalrntreatment of brewery effluent. Analysis of this waste material revealed that it containedrnvaluable nutrients for plant growth (total %N= 4.2, %P=2.5 K=106.4, and Zn 35.16 ppm),rnheavy metal content within acceptable range (Pb=0.62, Cd=0.04, Hg=0.22, Ni=34.09 andrnCo=0.77 ppm) and acceptable load of pathogenic microorganisms (5cfu/g for E coil).rnThe brewery sludge can be directly applied to the soil for the agricultural purposes. Thernmain objective of the present study is to compare the effects of BWS and urea fertilizerrnon the growth and yield of tomato (Lycopersicon esculentum Mill). BWS was applied atrn10, 25, 50, 75 and 100 % ratio with soil and urea fertilizer at 50, 100, 150 and 200rnmg/kg of soil. Results showed significance in leave height (17.67±0.58 cm) and shootrnlength (83.33±1.53 cm) were recorded at 25% ratio of BWS and lowest (No growth)rnat 75 and 100 % BWS ratio. In addition, 200mg urea /kg of soil recorded the highestrnshoot length (74.67±1.15cm) and 50 mg of urea /kg of soil lowest (64.67±0.58 cm), morernnumber of tomato fruits (16.33±1.53) were produced at 25% BWS compared withrn(13.00±1) in 200 mg of urea/kg soil and differed significantly (p
