ROLE OF SPENT MUSHROOM AND COMPOST TO CONTROL ROOT-KNOT NEMATODES ON EGGPLANT

Abstract

Eggplant (Solanum Melongena L.) are considered one of the most important economic vegetable crops in Egypt. It is a herbaceous plant that follows family Solanaceae. Nowadays it is widely grown in different seasons throughout the year in opened field and under greenhouse conditions. It contains proportions of dietary fiber, vitamins, and micronutrients. Results obtained from this present investigation can be summarized as follows: Adding organic wastes (plant compost, animal compost, maize wood compost, straw rice compost) resulted in soil cultivated with infectious eggplant plants with root-knot nematode to reducing the numbers of nematodes and egg and egg sacs and larval phases, adding the animal compost residue at a concentration of 10g proved to be the best in reducing the nematode clan compared to the treatment of nematodes only. The addition of both the plant compost tea and the animal compost tea to the soil cultivated with infested eggplant plants with root-knot nematode reduced the numbers of nematodes galls, egg masses and larval stages, and demonstrated the addition of the animal compost tea in a concentration 100g is the best in reducing the nematode compared to treatment with nematodes only. The addition of mushroom residue to soil cultivated with infectious eggplant plants with root-knot nematode reduced the numbers of nematodes and egg masses and larval stages, and the addition of mushroom residue with a concentration of 10% demonstrated that the best in reducing the nematode compared to treatment with nematodes only.
