Abstract

This study aimed at spreading of water purification sludge from Lukaya and the determination of the optimal proportion improving the growth of market gardening crops. The sludge from the purification of the Lukaya water treatment plant has been analyzed. The results indicate the presence of iron (9.8%), phosphorus (0.5%), nitrogen (0.5%), potassium (1.1%), magnesium (0.99%), carbon (0. 5%), aluminum (18.55%) and organic materials (1.2%).
Its spreading on Amaranthus hybridus cultivation soil has improved productivity. The optimal proportion is at the dose of 40% mud and 60% soil. In excess, this sludge reduces plant growth.
The variances analysis indicated that the F test is significant at the height of the plant due to the presence of iron which plays an important role in photosynthesis and chlorophyll, magnesium and phosphorus and not significant for the number of leaves and the weight of the plant.
