To study the effect of coffee pulp effluent irrigation on yield and yield attributing characters of banana, a field investigation was carried out during 2006 and 2007 at Kollibylu, Mudigere, Chikmagalur District. Application of raw coffee pulp effluent without microbial culture recorded higher fungi population (7.03 CFU x 104g-1) followed by all the other effluent irrigated treatments. Alternate irrigation with lime treated coffee pulp effluent and fresh water with microbial culture recorded higher bacterial population (9.00 CFU x 107g-1). Lime treated coffee pulp effluent irrigation with microbial culture recorded higher actinomycetes population (6.43 CFU x 103g-1). Lime treated coffee pulp effluent irrigation with microbial culture recorded higher dehydrogenase activity (336.9 μg TPF g-1d-1), raw coffee pulp effluent irrigation without microbial culture recorded higher urease activity (141.4 μg NH4-Ng-1h-1) and 1:1 ratio irrigation with lime treated coffee pulp effluent and fresh water with microbial culture recorded higher phosphatase activity (65.00 μ mol p-NPg-1h-1) as compare to the other treatments.
