The bioorganic fertilizer obtained through anaerobic fermentation comprises number of growth substances, vitamins, antibiotics, amino acids and useful micro-organisms. Bioorganic liquid fertilizer not only increases bioorganic fertility of crops (in comparison to the control and prototype fertilizer), but also accelerates their maturation and nutrient quality. Thus, the present study was aimed to produce bioorganic liquid fertilizer from cow manure and groundnut husks through aerobic fermentation in open containers. The result indicated that macronutrient composition of bioorganic fertilizer and compost tea solutions indicated that Potassium (K), Calcium (Ca), Magnesium (Mg) and also sodium (Na) were found to be significant between bioorganic liquid fertilizer and compost tea (used as a control) solutions. The quality of biorganic liquid fertilizer solution produced in the present study with respect to PH, EC and C:N ratio indicated that both compost tea and bioorganic liquid fertilizer solutions fulfill the basic requirements of plant macronutrients with respect to electrical conductivity and C:N ratio. However the PH needs adjustment to the neutral range between 6.0 to 8.0 which is optimum for most crop plants. It was indicated that the performance of lettuce irrigated with bioorganic fertilizer solution was performing better than compost tea solution and without any fertilizer (control) plant. Above ground biomass per plant (BMW) and Head weight per plant (HWP) was found to be significant among all treatments: lettuce irrigated with bioorganic liquid fertilizer; with compost tea, and without any fertilizer. It can be concluded from the present study that bioogranic liquid fertilizer can be produced from locally available substrates like cow manure and groundnut husks.
