Use of slaughterhouse waste and tannery-based organic compost for management of reniform nematode

A greenhouse experiment was carried out with the objective of evaluating the effect of increasing soil amendments (1, 3, 9, 15 and 30%, v/v) of organic compost produced from slaughterhouse waste and tannery residues on the reproduction of reniform nematodes and cotton development. The addition of organic composts to soil proportionately reduced the number of nematodes per gram of root and the reproduction factor. However, depending on the concentration of the compost, there was a reduction of height and dry mass of cotton shoots. We concluded that the organic compost produced with slaughterhouse and tannery waste has potential for controlling reniform nematodes, but requires dose adjustments or improvements in its composition to reduce the risk of phytotoxicity
