STUDIES ON EFFECT OF BREWERY WASTE WATER SLUDGE (BWS) ON MORPHOLOGY AND YIELD OF CHILLY (CAPSICUM ANNUM L.) PLANT.Abstract
In an effort to increase yields from a limited area, farmers tend to indiscriminately use more chemical fertilizers and pesticides. The brewery sludge can be directly applied to the soil for the agricultural purposes or it can be composted before utilizing for plant growth. The main objective of the present study is to test the efficacy of the bio-fertilizer in the growth and yield of Chilly Plant. A potted experiment was conducted to evaluate the potential of brewery sludge on different soil chemical properties and growth in chilly plant. The sun dried Brewery sludge was mixed with three different types of soils viz., clay loamy, river sand and red sandy loamy soil in different ratios. Chilly seeds pre incubated in water were sown in earthen pots. There was a significant increase in nitrogen and Potassium concentration in all the three amended soil samples (90%) where as decrease in Phosphate concentration in the amended soils. There was a realistic increase in plant growth in river sand as compared to red sandy loamy soils and clay loamy soils respectively. Heavy metal concentration was recorded below detectable levels which ensure brewery sludge for agricultural application.
