Conjunctive use of coffee effluent and pond water on the performance of robusta coffee and soil properties

A field experiment was conducted to study the influence of coffee effluent irrigation on performance of established robusta coffee, nutrient contribution and microbial activities in the soil. The results revealed that the field irrigated with coffee effluent from aerobic tank having COD of 1009 ppm, did not affect the yield of clean coffee (1309 kg ha-1) and it was on par with the plots irrigated with pond water (1310 kg ha-1).
