The paper approaches the problem of efficient utilization in agriculture of dehydrated sludge in geotubes - waste from urban wastewater treatment. The influence of three sludge doses of 23 t/ha, 46 t/ha and 92 t/ha on the crop yields was studied. The results have shown that administration of urban sludge has favored a significant increase in crop yields. The application of sludge over a period of six years in dose of 23-46 t/ha provided a specific crop yield of 174-92 in cereal units, in average - 133 kg/t. The sludge dose of 92 t/ha provided a specific increase on average for three years - 39.6 kg/t. The protein content, gluten in wheat grains and crude fat content in sunflower seeds increased in proportion to the applied dose of sludge. The increase in protein content was 1.5-2.5%, gluten 2.0-3.6% and oil 2.9-3.1%. Calculated on the incorporated sludge unit, it was found that the 23 t/ha sludge dose was recovered with higher yields and better quality indices compared to dose of 46 t/ha and 92 t/ha.
