INFLUENCE OF BIO-METHANATED DISTILLERY EFFLUENT ON SOIL BIOLOGICAL PROPERTIES AND SUGARCANE YIELD IN CALCIORTHENTS OF BIHAR
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
A field experiment was established during 2011-12 in calcareous soil of Bihar to study the effect of bio-methanated distillery effluent on biological properties and yield of sugarcane crop. Seven treatment combinations of bio-methanated distillery effluent (BMDE) and graded dose of nutrients were tried in randomized block design. Results revealed that the integrated application of bio-methanated distillery effluent (150 m3/ha BMDE) and 100% of NPK nutrient significantly improved the biological properties viz., bacteria population (37.40%), fungi population (69.23%), azotobactor population (84.31%), Phosphatase activity (45.00 µg nitrophenol/g soil/h), Dehydrogenase activity (10.00 µg TPF/g soil/h) and urease activity (18.00 µg NH4-N/g soil/h) as compared to control. The improvement in soil biological properties in treatment consisting combinations of BMDE and 100% NPK were produced satisfactory cane yield (129.4%) over control. The positive polynomial correlations was observed between soil organic carbon and urease activities which is clearly demonstrate the important role of organic carbon on improving in biological properties of soil.
