PRODUCTION OF BIOORGANIC LIQUID FERTILIZER FROM CAMEL MANURE AND ONION BULBS THROUGH HYDROPONIC

ABSTRACT The bioorganic fertilizer obtained through aerobic fermentation comprises a 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 camel manure and groundnut husks through aerobic fermentation in open containers. The results indicated that Potassium (K), Calcium (Ca) and sodium (Na) were found to be significant between bioorganic liquid fertilizer and compost tea (used as a control) solutions. However, there were differences with respect to Carbon(C), Nitrogen (N), phosphorus (P) and Magnesium (Mg) contents .Comparison of mineral composition of bioorganic liquid fertilizer and compost tea solutions with the standard for some macronutrients requirement of plants indicated that the composition of both fertilizer solutions in the present study satisfies the standard with bioorganic liquid fertilizer being higher in mean values for most of the studied mineral plant nutrients. The bioorganic liquid fertilizer produced was evaluated by growing lettuce in pot experiment and result indicated that the performance of lettuce with bioorganic fertilizer was better than that of compost tea solution and soil grown plants. It can be concluded from the present study that bioorganic liquid fertilizer can be produced from locally available bioorganic fertilizer. Small holder farmers can get economic relief, because by using this technology, they can minimize the use of chemical fertilizer which is being expensive and not environmentally friendly.
